Cross-Chain Solutions

Braavos integrates cross-chain bridging from 21 source networks — including Solana, Ethereum, Arbitrum, Base, Polygon, zkSync Era, Optimism, and BSC — into its smart contract wallet interface through partners including rhino.fi, Owlto, Orbiter, and Starkgate. This positions it as a seamless entry point for users moving assets from Solana into Starknet's DeFi ecosystem without managing separate bridge applications. On the destination side, Braavos manages Starknet positions including native staking for ETH, STRK, and Bitcoin, along with yield products and DEX swaps routed through AVNU. Its account abstraction model adds programmable security rules to cross-chain inflows, letting users set spending limits and multi-factor requirements that apply regardless of the asset's origin chain.

BridgeEye, ChainEye's flagship tool, is a cross-chain bridge comparison engine connected to over 24 bridging protocols including Across, Allbridge, Stargate, cBridge, and Connext, as well as centralized exchange withdrawal routes from Binance, OKX, KuCoin, and Bybit. When users want to transfer assets across chains, BridgeEye fetches live quotes from every supported route and presents them sorted by total cost, collapsing swap fees, bridge fees, and gas into a single comparable figure. Users can re-sort results by speed or bridge TVL sourced from DefiLlama to optimize for different goals, while hovering over any bridge name surfaces its audit status and financing details as a quick due-diligence check. A No Token filter helps airdrop hunters identify bridges that have not yet issued a native token, and the inclusion of CEX routes alongside DeFi bridges acknowledges that centralized exchange hops are sometimes the most cost-effective cross-chain path.

rhino.fi is a cross-chain stablecoin infrastructure platform that enables USDC and USDT to move seamlessly across 30+ blockchains including Ethereum, Solana, Tron, Base, Arbitrum, Optimism, BNB Chain, TON, Polygon, zkSync, Starknet, Stellar, and others. Its core routing engine accepts stablecoin deposits from any supported chain and settles them to the integrator-specified destination in under ten seconds, with a reported 99.99% transaction success rate. Originally launched as Ethfinex in 2019 before evolving through the DeversiFi brand into rhino.fi, the platform processed over $15 billion in stablecoin volume by mid-2026. Built on StarkEx Validium — a zero-knowledge Layer 2 architecture that anchors user funds to Ethereum security — rhino.fi Smart Deposit Addresses accept any-chain inbound stablecoin flows and route them automatically, eliminating manual bridging steps for enterprise integrators and supporting configurations that trigger smart contract calls immediately after funds arrive.

SimpleSwap functions as a cross-chain exchange aggregator, enabling users to convert assets between Bitcoin, Ethereum, Solana, and dozens of other networks through a single interface without registering an account. Each swap routes through a network of more than 20 liquidity providers spanning both centralized exchanges and decentralized protocols, handling the multi-hop complexity that would otherwise require users to manually coordinate across bridges and exchanges. For Solana users, cross-chain conversion is a primary use case: BTC-to-SOL and ETH-to-SOL rank among the platform's highest-volume pairs, and the service supports SPL tokens and Solana-based stablecoins. In 2025 and 2026, SimpleSwap added more than 450 assets across newer ecosystems including Solana, Sui, Base, and Ronin. Solana's fast block times mean swap confirmations for SOL-based pairs often complete within a minute on SimpleSwap's end, compared with the 10–30 minutes typical of Bitcoin or Ethereum network confirmations.

Wombat Exchange supports cross-chain liquidity pools using Wormhole as the bridging layer, allowing liquidity providers to deposit on one chain and deploy capital across multiple networks within a single LP position. The Wombat 2.0 roadmap extends the protocol beyond BNB Chain to Ethereum, Arbitrum, Solana, and additional networks. This architecture lets LPs consolidate yield from multiple networks without managing separate positions on each chain. When deployed on Solana, Wombat's cross-chain pools would allow liquidity providers to unify BNB Chain and Solana stablecoin liquidity, bringing a protocol with more than $3.9 billion in cumulative trading volume and 140-plus supported assets to Solana's DeFi ecosystem.

Chainspot is a non-custodial, omnichain protocol that integrates 14+ bridge protocols and Asterizm's cryptographic cross-chain messaging infrastructure, enabling asset transfers across 36+ blockchain networks through a single interface. Its routing engine calculates the optimal cross-chain path in real time, and a gas refuel feature allows users to top up zero-balance wallets on destination chains, removing a common barrier to cross-chain operations. Solana was added as a supported network in November 2024 via an updated Wanchain API integration, enabling routing into and out of Solana. The platform supports 10,000+ tokens and 176 wallets via WalletConnect, and claims fee savings of up to 80% compared to standard bridging. Smart contracts were audited by HashEx in Q4 2022 and Decurity in Q3 2024, and yield management contracts are non-upgradable.

HOT Protocol is a chain abstraction infrastructure layer built around a decentralized Multi-Party Computation (MPC) network and OmniBridge, enabling native asset transfers between 140+ blockchains—including Solana—in approximately 30 seconds, with zero bridge fees between supported omni-balance chains. Assets deposited from Solana are locked in chain-specific locker contracts and represented as omni-tokens on NEAR Protocol, the canonical state layer, with burns triggering native asset release on destination chains. Solana is a first-class supported chain within HOT Protocol, with native Ed25519 signature support enabling seamless integration without EVM proxy infrastructure. HOT Wallet, the end-user product built on the protocol, routes Solana swaps through Jupiter aggregation, supports direct SOL staking without lock-up periods, and extends Solana DeFi access across Ethereum, Bitcoin, TON, and other ecosystems through a single non-custodial interface.

Houdini Swap operates as a cross-chain routing layer that aggregates liquidity across 32 exchange partners and bridges covering more than 100 blockchain networks. Rather than pooling funds, it evaluates available liquidity paths and executes the optimal route for each swap. Its private mode routes transactions through two off-chain exchange partners and three separate blockchains, using Monero as a tunneling asset to sever the on-chain link between input and output wallets. The platform provides a developer API and partner portal for wallets, dApps, and exchanges to integrate its cross-chain routing. Partnership arrangements include Mayan Finance, Bungee Exchange, and leading Solana wallets. Newly deployed Solana tokens become available for cross-chain swaps immediately upon deployment. Houdini was acquired by SOL Strategies Inc. (NASDAQ: STKE) in June 2026 for $18 million, adding a transactional revenue layer to that firm's Solana validator and liquid staking platform.

Meson Finance is a cross-chain stablecoin swap protocol enabling transfers of USDT and USDC across more than 60 blockchain networks, including Solana, with settlements completing in one to two minutes. The protocol uses Hash Time Lock Contracts and a pre-funded liquidity provider model, where LPs deposit stablecoins on each supported chain so user swaps settle without waiting for cross-chain message confirmation. Liquidity providers cover gas costs on both source and destination chains through meta-transactions, so users need not hold native gas tokens on any chain involved. Unlike wrapped-token bridges, Meson delivers native USDC for native USDC and native USDT for native USDT, eliminating synthetic intermediaries and the slippage or depeg exposure they introduce. Four completed security audits — three from Trail of Bits — back the protocol's design, and its HTLC mechanism guarantees that failed swaps return funds to the sender automatically. Adding a new chain requires only deploying contracts on that chain, giving Meson a linear rather than quadratic scaling model as the multi-chain ecosystem expands.

Oraichain delivers cross-chain infrastructure through the Inter-Blockchain Communication (IBC) protocol, enabling direct asset transfers and messaging between Oraichain and other Cosmos-compatible chains. Its Verifiable Random Function (VRF) 2.0 service is live across six external networks — BNB Chain, Ethereum, Polygon, Solana, Avalanche, and Fantom — giving smart contracts on those chains access to provably fair, on-chain-verifiable randomness generated by Oraichain validators using threshold cryptography. OWallet, the ecosystem's multi-chain wallet, added native Solana network support and token management in January 2025, unifying Cosmos, EVM, and Solana asset management in a single interface. OraiDEX uses IBC for cross-chain liquidity and has roadmapped native Solana and Sui trading pairs for H2 2025. Layer 2 subnetworks built on Optimistic and Zero-Knowledge Rollups extend Oraichain's compute capacity cross-chain, with the VRF subnetwork operational and an AI Execution subnetwork in active development.

Router Protocol is a cross-chain swap network built on the Open Graph Architecture (OGA), a chain-agnostic execution layer that unifies liquidity from bridges, DEXs, and solver nodes across more than 30 blockchains. The platform discovers optimized routes in real time and splits large orders across up to 30 bridges simultaneously, targeting sub-10 basis point execution costs on trades up to $50 million and 99.5% settlement reliability. Solana is a supported non-EVM chain within the OGA network, with Jupiter serving as the native Solana liquidity source. Router Nitro, the cross-chain bridge component, supports deposits from over 30 chains including Solana and had processed more than 1.5 million transactions and $1 billion in volume by early 2025. Hyperliquid integrated Router Nitro in January 2025 to support cross-chain deposits from Ethereum, Solana, Sui, Tron, and Base.

Rubic is a cross-chain aggregator routing swaps across more than 70 blockchains through 340+ integrated DEXs, bridges, and intent protocols — packaged into a single non-custodial transaction the user signs once. Its routing engine queries available liquidity paths in real time and selects the optimal route, supporting EVM chains, Layer 2 networks, and non-EVM chains including Solana, Bitcoin, and TON without requiring separate wallet sessions or manual bridge steps. For Solana users, Rubic integrates the network as both source and destination for cross-chain swaps, routing Solana-native assets through aggregated DEX liquidity including Raydium and handling cross-chain transfers via its integrated bridge providers. Users on other chains can access Solana-based assets in a single interface operation, while Solana users can move into liquidity on any of the 70+ supported networks.

SwapSpace facilitates cross-chain transfers involving Solana by aggregating live quotes from 40+ instant-swap partners, allowing users to move SOL and Solana-based tokens across Bitcoin, Ethereum, BNB Chain, Avalanche, and other networks without a centralized exchange account. It returns a ranked comparison of fixed and floating-rate offers from its full partner network simultaneously, so users can evaluate rates and execution speed before committing. The platform is non-custodial throughout: funds route directly through the chosen partner's deposit infrastructure and arrive in the user's own wallet, typically within 10 to 30 minutes. Partners include Changelly, ChangeNOW, SimpleSwap, StealthEX, Exolix, and SideShift, among others. A fiat on-ramp via Mercuryo supports entry into Solana assets from 90+ traditional currencies, rounding out SwapSpace's cross-chain utility for Solana holders.

Symbiosis Finance is a decentralized cross-chain AMM enabling token swaps across 51 blockchain networks — including Ethereum, Arbitrum, Solana, Bitcoin, TON, and BNB Chain — in a single transaction without centralized bridges or wrapped token intermediaries. Routing is handled automatically using one of three transit tokens (USDC, WETH, or WBTC), with Octopools serving as the liquidity reservoir connecting chains through synthetic sToken representations. For Solana users, Symbiosis enables direct swaps to and from any of its 51 supported networks, with cross-chain routing utilizing the Chainflip bridge on Arbitrum. A Zap feature extends this to one-click cross-chain deployment into third-party DeFi protocols, allowing Solana users to move liquidity into yield positions on other chains without executing multiple manual steps.

Transit Swap integrates four dedicated bridge protocols, enabling users to transfer assets between sixteen supported blockchains within a single interface and without interacting with standalone bridge frontends. Supported networks include Solana, Ethereum, Binance Smart Chain, Polygon, Avalanche, Arbitrum, and Optimism, among others. Cross-chain swaps route through the same aggregation engine used for same-chain trading, consolidating both functions into one transaction flow. The cross-chain capability sits alongside same-chain DEX aggregation across 122 protocols, fiat on/off ramps through seven providers, and market analytics tools. Transit Finance was incubated by TokenPocket and launched in 2021. Its dedicated Solana Mainnet program settles the Solana side of cross-chain transactions, positioning Transit Swap as an option for Solana users who hold or trade assets across multiple blockchain ecosystems.

Tria's BestPath AVS is a decentralized settlements marketplace routing transactions across 200+ blockchains — including Ethereum, Solana, Arbitrum, Base, Polygon, Cosmos, and Bitcoin — through competing solvers, routers, and relayers that select the Pareto-optimal path for each transaction. Operating as an Actively Validated Service on EigenLayer, BestPath delivers gasless cross-chain execution so users never need to bridge assets manually or hold native gas tokens on destination chains. By October 2025, BestPath had served 250,000+ users and integrated with 70+ protocols. Tria pairs BestPath with ERC-4337 account abstraction and MPC custody, enabling single-login access to any supported chain without seed phrases. The TriAI layer translates natural-language commands into multi-step cross-chain transactions, while the Unchained Layer 2 provides a unified settlement layer with IBC compatibility. Solana is treated as a first-class execution environment on par with EVM chains, allowing SOL holders to swap and spend cross-chain without switching wallets.

Polymer Hub enables trustless cross-chain asset transfers across Ethereum's rollup landscape using ICS-20, the IBC standard for fungible token transfers already battle-tested in the Cosmos ecosystem. Lock-and-mint patterns allow assets to move between connected rollups—Base, OP Mainnet, Mode, and World Chain among them—with standard accounting guarantees and no reliance on custodial bridge operators. Zero-knowledge proofs verify source chain state directly on-chain, reducing trust assumptions to the soundness of the proof system and Ethereum L1 security rather than committee attestation. A live integration with LI.FI and Jumper Exchange delivers zero-slippage USDC bridging using Circle's Cross-Chain Transfer Protocol with Polymer's Execute API as the relayer layer. The Standard route provides 1:1 USDC transfers with complete price certainty, while a Fast route settles in six to ten seconds with approximately 0.02% slippage for time-sensitive flows. In July 2026 the integration expanded to Injective, extending Polymer's cross-chain asset footprint from OP Stack rollups into the broader Cosmos ecosystem.

iMe Wallet 2.0 operates across 17 blockchain networks including Ethereum, BNB Chain, Polygon, Solana, Base, Arbitrum, Bitcoin, Blast, Celo, Fantom, Optimism, TON, and zkSync. The wallet is embedded in both the iMe messenger app and a Telegram Mini App, allowing cross-chain access without additional software downloads. Fiat on-ramps and off-ramps, QR code transfers, NFT management, and portfolio analytics round out the multi-chain interface built directly into a messaging environment. The wallet's broad chain support reflects iMe's positioning as a blockchain-neutral platform at the infrastructure level, even as the LIME token itself migrated from Solana to BNB Chain and Ethereum. Solana remains a supported network within the wallet, allowing users to manage Solana-based assets from within the app. Multi-seed security with advanced encryption and a non-custodial architecture ensure users retain control of private keys across all connected chains.

Exolix routes cryptocurrency exchanges across more than 200 blockchains, aggregating liquidity to enable asset movement between disparate networks without requiring users to manage bridge contracts or multi-step transfer processes. A one-time deposit address is generated per transaction, and funds are delivered to the destination wallet after on-chain confirmation on the source network. The platform handles routing, settlement, and delivery internally, functioning as infrastructure for cross-chain asset flows with an average processing time under five minutes. Solana is integrated as a supported chain, enabling direct swaps between SOL and assets on Bitcoin, Ethereum, Monero, Zcash, and thousands of other networks. Exolix is included in cross-chain aggregators such as Beam, OrangeFren, and Trocador, and as of mid-2026 reports more than 130 active API integration partners that embed its swap backend within their own applications. No upper bound on transaction size is set, supporting both retail and higher-volume cross-chain transfers. The platform's inclusion in multiple aggregator directories reflects its established position within cross-chain routing infrastructure on Solana and beyond.

0xProcessing operates across 18 blockchain networks, positioning itself as a multi-chain payment infrastructure layer for businesses. Supported chains include Bitcoin, Litecoin, Dogecoin, Bitcoin Cash, Ethereum, BNB Chain, TRON, Avalanche, Polygon, TON, Base, and Solana, giving merchants a single API integration point that spans the major public blockchain ecosystems. The platform routes payments through its own proprietary blockchain infrastructure rather than third-party aggregators, a design the team describes as reducing counterparty exposure and improving security in the transaction path. Merchants receive a unified settlement experience regardless of which chain a customer pays on, with automatic cross-chain stablecoin conversion available through the Volatility Risk Control System. Over 16 Web3 wallet integrations are supported across chains, including Phantom for Solana, MetaMask, WalletConnect, Trust Wallet, Coinbase Wallet, and Rabby. Minimum transaction amounts begin at two dollars, with maximums varying by currency and method up to sixty thousand dollars. Customers can complete payments by connecting a browser wallet directly to the merchant checkout page, with the platform handling cross-chain address generation and payment confirmation tracking. The breadth of supported networks allows merchants in iGaming, e-commerce, and forex to serve customers regardless of which blockchain network they prefer to pay from.

FixedFloat operates as a cross-chain exchange supporting more than 100 cryptocurrencies across multiple blockchain networks, handling the complexity of multi-chain settlement within a single automated swap interface. Supported assets span Bitcoin with Lightning Network compatibility, Ethereum, Solana, TRON, Cardano, Polkadot, Ripple (XRP), Monero, Litecoin, Dogecoin, and Zcash, as well as stablecoins such as USDT and USDC deployed across Ethereum ERC-20, TRON TRC-20, and additional networks. Users specify a source asset and a destination asset, send funds to a generated deposit address, and receive the converted amount at the destination address once confirmations clear, without needing to manually bridge, wrap tokens, or interact with separate protocol interfaces. For Solana participants specifically, FixedFloat provides a route to move SOL and SPL tokens to Bitcoin, Ethereum-based assets, privacy coins like Monero, or stablecoins on other networks without connecting a wallet to an on-chain protocol or submitting to a centralized exchange. The platform also exposes a documented REST API supporting real-time exchange rate queries, order creation and tracking, QR code generation, and edge-case handling for expired deposit windows. Authentication uses HMAC SHA256 signing and the rate limit is 250 weighted request units per minute, with order creation costing 50 units. Developers building Solana-adjacent products that require cross-chain conversion can integrate FixedFloat's swap functionality and affiliate program parameters directly through this API.

Crystal Trade supports more than 1,500 exchange directions spanning Bitcoin, Ethereum (ERC-20), Arbitrum, Optimism, Tron (TRC-20), BNB Chain (BEP-20), Polygon, and Solana, functioning as a cross-chain bridge-adjacent service for users moving value between networks. Solana (SOL) is available as both a source and a destination asset, enabling single-step conversions from Bitcoin, USDT, ETH, and other assets into SOL — or exits from SOL positions into stablecoins on other chains — without routing through multiple DEXes or bridges. A REST API allows developers and businesses to embed this multi-chain exchange functionality into their own products, with seventeen endpoints covering the full order lifecycle from currency-pair queries to settlement confirmation. A partner program with referral tracking and earnings-withdrawal endpoints makes the service suitable for affiliate-style cross-chain integrations.

Uniwire supports a broad set of blockchains within a single payment gateway, covering Bitcoin, Ethereum, Solana, Litecoin, Dogecoin, Ripple, and Tron as Layer-1 native assets alongside tokens on Binance Smart Chain, Polygon, Arbitrum, Base, Celo, and the Liquid Network Bitcoin sidechain. Bitcoin Lightning Network support is a core offering that predates the platform's multi-chain expansion and was central to its original identity under the CryptoChill name. The modular architecture explicitly allows liquidity providers, on-ramps, and off-ramps to be swapped independently without rearchitecting existing client integrations, insulating businesses from provider-level disruptions. Solana integration arrived in July 2024, with Uniwire supporting native SOL, USDT, USDC, Wrapped Solana, Bonk, and Official Trump tokens at the native network layer rather than through bridges or wrapped representations. This direct integration avoids the custody risks associated with cross-chain intermediaries while giving merchants access to Solana's sub-second finality and sub-cent transaction fees. Additional SPL tokens can be enabled on a per-client basis, extending multi-chain coverage within the Solana ecosystem beyond the default supported assets.

Ave.ai supports more than 190 blockchain networks, including Ethereum, BNB Smart Chain, Solana, Arbitrum, Base, Avalanche, Tron, and TON, making broad multi-chain coverage a defining element of its platform strategy. The roster expands regularly; a recent addition was the Stable chain, a Layer 1 designed for stablecoin payments and meme token trading. This coverage targets the long tail of active blockchain ecosystems rather than concentrating solely on the largest networks. Aggregating data from over 300 decentralized exchanges across this scope gives Ave.ai a cross-chain footprint that few comparable platforms match. Cross-chain bridging between EVM-compatible networks and Solana lets users move assets and act on opportunities across ecosystems without leaving the platform. The meme coin dashboard surfaces trending tokens from multiple chains in a single view, enabling direct cross-chain comparison. Ave.ai made specific performance investments in Solana support, overhauling its execution system for millisecond-level trading on the network. This architecture positions it as a trading layer built for users who routinely operate across blockchain boundaries.

3xpl provides a cross-chain blockchain data layer that normalizes raw chain data into a universal internal format, returning identically structured responses whether developers query Solana, Ethereum, Bitcoin, or any of the 45 other supported networks. This abstraction means a developer building a multi-chain application can use the same ClickHouse schema for Solana data as for Ethereum or Bitcoin, reducing integration complexity for cross-chain analytics and compliance workflows. Multiple programmatic access modes support cross-chain use cases: a JSON API, WebSocket API, ClickHouse API for analytical SQL queries, an LLM API for AI-integrated workflows, and downloadable database dumps for offline research. The open-source indexing modules allow external developers to contribute chain integrations that conform to the same universal data format, accelerating coverage of new networks while maintaining the consistent cross-chain interface that makes multi-chain development practical.

Xgram provides chain-agnostic cross-chain swap infrastructure that routes between more than 40 blockchains — including Solana, Bitcoin, Ethereum, TRON, Arbitrum, BNB Chain, Polygon, and Optimism — without requiring users to rely on traditional bridges or wrapped tokens. The platform's hybrid liquidity engine handles the cross-chain leg internally, enabling direct swaps between assets on different networks in a single user-facing flow. A multi-output swap feature allows a single deposit to be routed to multiple destination wallets simultaneously, supporting batch payout and portfolio distribution workflows across chains. An open API and embeddable widget extend this cross-chain capability to third-party wallets, applications, and automated trading systems.

Explace functions as a multi-chain access layer connecting dozens of blockchain networks through a unified swap interface. Rather than operating natively on any single chain, it aggregates liquidity providers across networks, enabling users to move assets between Solana, Bitcoin, and dozens of other chains without an account or KYC process. Its cross-chain architecture relies on third-party provider integrations, and the platform surfaces competing provider quotes so users can comparison-shop before committing to a swap. Solana is supported as both a source and destination network, giving SOL and SPL-token holders access to cross-chain liquidity without using a Solana-native DEX. Developers and businesses can integrate via API or embed the exchange widget to offer cross-chain swap functionality in their own products. Aggregation partnerships with services including ScanBit, MarketExchangers, and TrocadorApp further extend the platform's reach across the multi-chain exchange landscape.

QuickEx is a cross-chain swap router that enables users to move value between Solana and dozens of other blockchain networks — including Bitcoin, Ethereum, and Tron — without creating an account or passing through identity verification. The platform supports native SOL and Solana-native tokens such as JUP (Jupiter), allowing users to acquire or exit Solana positions from BTC, ETH, USDT, and other major assets. With over 100 supported cryptocurrencies spanning ERC-20, TRC-20, BEP-20, and native chains, and more than 100,000 trading pairs exposed via its developer API, QuickEx covers a wide range of cross-chain routes. Settlement is handled off-chain by QuickEx acting as a centralized exchange router: once the user sends funds to the platform's deposit address, the converted asset is credited directly to the specified destination wallet on the target chain, with an average processing time of approximately two minutes. No smart contracts are deployed on Solana — the cross-chain conversion is managed entirely by the platform's infrastructure. The non-custodial model ensures user funds are only held during the active trade window, limiting exposure to platform-level risk. A white-label API and embeddable widget extend this cross-chain capability to third-party developers and business integrations.

xRocket's custodial wallet enables deposits and withdrawals across six blockchains — TON, Bitcoin, Ethereum, BNB Chain, TRON, and Solana — making it one of the broader multi-chain platforms accessible entirely through Telegram. SOL and Solana-based tokens can be deposited, held, traded, and transferred within the platform, giving Solana holders direct access to the xRocket exchange ecosystem. The platform maintains the majority of user assets in cold wallets, providing a security layer for cross-chain holdings under custodial management. New token listings, including those from non-TON chains, are governed by DAO community vote rather than a centralized committee. Internal transfers between xRocket users are fee-free across all supported chains, lowering the cost of moving assets within the platform's ecosystem. The trading engine runs a centralized order book with market and limit orders, supporting cross-chain asset participation in more than 90 trading pairs. Tiered trading fees reward active users, and the XROCK native token provides additional fee discounts for holders. The 2026 roadmap outlines further blockchain integrations, signaling continued expansion of xRocket's multi-chain reach beyond the current six networks.

LetsExchange operates as a cross-chain swap aggregator spanning more than 300 blockchain networks, with a 2024 partnership with Swing.xyz that extended routing to over 100 additional blockchains, bridges, and DEXes. This infrastructure enables multi-hop swap paths that connect the Solana ecosystem to non-EVM chains that most Solana-native bridges do not directly serve. Supported cross-chain pairs include SOL-to-BTC, SOL-to-ETH, and SOL-to-USDT across multiple networks, alongside bridging of Solana-native tokens to other ecosystems via the platform's aggregation layer. The routing engine queries 20+ liquidity providers simultaneously and selects the best executable path at execution time, covering both CeFi and DeFi swap types. Users retain full self-custody throughout: funds move directly from their wallet to the destination address without passing through LetsExchange accounts, removing the custody risk that often accompanies cross-chain bridging via centralized intermediaries. The Exchange API exposes this same cross-chain routing to third-party wallets and aggregators — recent integrations include Unstoppable Wallet and Console Wallet — making LetsExchange a backend infrastructure layer for the broader cross-chain ecosystem.

Pontem Network builds cross-chain infrastructure through its Lumio L2 framework, the first VM abstraction system allowing transactions to execute on one virtual machine and settle on a different Layer 1. Lumio supports the Move VM, EVM, and the Solana Virtual Machine as execution environments, settling on Ethereum, Solana, and other L1s. This enables composability across runtime environments that would otherwise be siloed, with active deployments including an Ethereum Mainnet canary and a Solana Devnet. Beyond Lumio, Pontem's multichain wallet supports assets across Ethereum, Solana, Aptos, and Sui in a single interface. The May 2025 acquisition of Martian Wallet, which had over 2 million installs across Aptos and Sui, further expanded the cross-ecosystem footprint. Liquidswap, Pontem's DEX, is also extending its deployment to Solana and TON beyond its native Aptos base.

CoinoSwap is a multi-chain exchange aggregator that pulls real-time rate quotes from 9+ partner exchanges and presents users with ranked options for swapping across more than 1,500 cryptocurrencies spanning dozens of blockchain networks. Solana (SOL) is a supported asset, available for cross-chain swaps into and out of non-EVM assets, privacy coins, stablecoins, and major chains like Bitcoin and Ethereum through partners such as StealthEX and ChangeNOW. The three-step interface — select assets, choose a quote, submit a wallet address — requires no account and enables wallet-to-wallet settlement across chains with no custody transfer to the aggregator. CoinoSwap operates as an off-chain routing and rate-comparison layer rather than a native on-chain bridge, aggregating both fixed-rate and floating-rate offers simultaneously so users can weigh price certainty against potential output. The platform earns through affiliate partnerships, keeping displayed quotes aligned with actual partner pricing. For SOL holders, CoinoSwap provides a no-KYC path to move value across blockchains without using a centralized exchange account, serving as lightweight cross-chain infrastructure for users prioritizing speed and privacy over on-chain trustlessness.

OxaPay routes payments across six networks—Ethereum, Tron, BNB Chain, Polygon, Bitcoin, and Solana—through a single merchant integration supporting more than 20 digital assets. Its Web3 Pay wallet-connect flow handles Solana, EVM chains, Bitcoin, Tron, and TON, letting customers pay directly from their native wallet without copying addresses or scanning QR codes. Mixed Payment support allows customers to split a single invoice across multiple currencies, removing the barrier of acquiring a specific coin before checkout. Multi-chain confirmation and settlement are abstracted into a consistent webhook notification model, so merchants receive the same event format regardless of which network the customer uses. For Solana specifically, OxaPay highlights fast finality and low fees as advantages during congestion periods on other chains. Auto Convert can settle any incoming cross-chain payment—including SOL—to USDT automatically, giving merchants stable, fiat-denominated revenue across all supported networks.

CryptoCloud operates as a multi-chain payment infrastructure platform supporting 40+ cryptocurrencies across Bitcoin, Litecoin, Ethereum, Tron, BNB Smart Chain, The Open Network (TON), Solana, and Ethereum Layer 2 networks Base, Arbitrum, and Optimism. The platform abstracts cross-chain complexity behind a unified API and merchant dashboard, so a single integration allows simultaneous acceptance of payments across all supported blockchains. Automatic stablecoin conversion can settle any incoming payment as USDT regardless of the network or asset the customer sends, providing consistent accounting across fragmented blockchain ecosystems. A unified withdrawal flow handles all chains, with funds reaching external wallets within 30 minutes and bulk payouts available via API. On Solana, CryptoCloud supports SOL, USDT, USDC, PYUSD, and TRUMP, leveraging Solana's low transaction costs and fast confirmation speeds for payment-grade settlement. The platform manages wallet address generation, on-chain monitoring, and cross-network settlement centrally, shielding merchants from the operational complexity of running payment infrastructure across multiple chains. By presenting one dashboard for all supported networks, CryptoCloud allows online businesses to offer Solana payments alongside higher-fee networks without engineering separate confirmation logic per chain — a key infrastructure consideration for merchants targeting global, multi-currency customer bases.

CryptAPI operates across 11 blockchain networks from a single API integration, allowing merchants and developers to accept payments in over 90 cryptocurrencies without maintaining separate payment processor relationships for each chain. Supported networks include Solana, Bitcoin, Litecoin, Dogecoin, Zcash, Ethereum, Tron, and several EVM-compatible chains — Arbitrum One, Polygon, Avalanche-C, Base, Optimism, Linea, Berachain, and Monad. This broad cross-chain coverage enables a single checkout integration to serve buyers transacting across the major blockchain ecosystems simultaneously. The platform's forwarding model handles network-specific complexity transparently: regardless of which supported chain a buyer uses, CryptAPI generates an appropriate deposit address, monitors on-chain confirmations for that network, and forwards the settled funds to the merchant's wallet on the same chain. Solana is included as one of the 11 supported networks, with native SOL and Solana-based tokens accessible through the same REST API and e-commerce plugins used for all other chains. The same tiered fee schedule — ranging from 1% at low volumes down to 0.25% at $10 million monthly throughput — applies uniformly across networks, simplifying cost modeling for multi-chain payment acceptance.

Mesh operates as a chain-agnostic payments infrastructure layer that unifies 24+ blockchain networks — including Solana, Ethereum, Polygon, Base, Stellar, Tron, and Tempo — into a single payments experience. Its SmartFunding technology allows a single checkout transaction to draw on up to five separate funding sources across multiple chains, converting assets on the back end and settling in the merchant's preferred currency without requiring the consumer to manually bridge or swap assets beforehand. This architecture abstracts cross-chain complexity into a single API integration for merchants, functioning as a high-level settlement layer rather than a traditional bridge. For the Solana ecosystem specifically, Mesh supports SOL as an accepted payment input and USDC on Solana as a settlement output, giving it a dual role in cross-chain value flows. Integration partnerships spanning MetaMask (Consensys), Bitget Wallet, Revolut, World App, Shift4, Paxos, and Ripple — alongside a network of 300+ connected wallets and exchanges — give Mesh one of the broadest multi-chain asset connectivity footprints in crypto payments infrastructure. With over $200 million raised from Paradigm, Dragonfly Capital, Coinbase Ventures, and PayPal Ventures, and a unicorn valuation confirmed in January 2026, Mesh has the institutional backing to continue expanding its cross-chain settlement rails globally.

Echo Protocol functions as a cross-chain Bitcoin infrastructure layer with active vault products spanning Solana, Aptos, Movement, Morph, and Hemi, making it one of the few Bitcoin staking protocols simultaneously serving both Solana and Move ecosystem chains. Users can deposit native BTC or supported BTC variants including fBTC, wBTC, uBTC, and multiple LSTs and have their unified BTC token minted on whichever target chain they select, enabling seamless capital deployment across ecosystems without manually bridging multiple assets. The protocol architecture aggregates fragmented BTC liquidity from dozens of wrapped standards into a single cross-chain asset backed by real-time Proof-of-Reserve attestation. For Solana users specifically, Echo provides a connectivity layer between Bitcoin deep capital reserves and Solana high-throughput DeFi environment, allowing BTC holders to earn both base-layer Bitcoin restaking yield and Solana-native DeFi returns in a single vault position. Cross-chain integrity is maintained by Chainlink and Redstone oracle providers ensuring unified BTC 1:1 peg holds regardless of which network the token is deployed on. With total protocol TVL exceeding 641 million and backing from The Spartan Group, ABCDE Capital, and Maelstrom, Echo has established itself as a credible multi-chain infrastructure layer connecting Bitcoin capital to high-throughput DeFi ecosystems.

NEAR Intents enables cross-chain asset transfers across 31 or more networks — including Solana, Ethereum, Bitcoin, Arbitrum, Base, TRON, and Starknet — using a threshold signature scheme called Chain Signatures instead of traditional bridge infrastructure. When a user initiates a transfer, NEAR validators co-sign the required transactions on external blockchains, allowing final settlement to span multiple chains without a trusted bridge operator or wrapped asset intermediary. New chains can be added to the routing set without requiring users or integrators to make changes to their implementations. The protocol has processed over 25 million cross-chain swaps and crossed $20 billion in cumulative volume by mid-2026. Major infrastructure providers including LI.FI, Brave Wallet, Starknet, and SimpleSwap have integrated NEAR Intents to give their users access to chain-abstracted liquidity flows. For Solana applications, NEAR Intents provides an inbound liquidity channel that does not rely on bridged token wrappers, enabling one-step cross-chain swaps such as ETH on Ethereum directly to USDC on Solana.

Talisman is built explicitly for cross-chain asset management, supporting more than 900 blockchain networks from a single browser extension — spanning EVM-compatible chains, Solana, and the full Polkadot and Substrate ecosystem. Rather than isolating users within a single network, Talisman creates and manages separate account types for each chain family (EVM, Substrate, and Solana) while surfacing all holdings in one unified portfolio view, removing the need to context-switch between network-specific wallets. Cross-chain swapping is available directly through the Talisman DeFi Portal, with curated routes handling the underlying bridging and wrapping complexity so users do not need to manually manage those steps. For Solana users who also hold EVM or Polkadot assets, Talisman provides consolidated visibility and movement of funds across ecosystems without requiring separate tools for each chain, making it a practical choice for multichain participants.

Xyra Labs is architected around multi-chain interoperability, operating natively across nine or more blockchains — including Solana, Aptos, Sui, Ethereum, Polygon, BNB Chain, Arbitrum, and Avalanche — through a single unified interface that eliminates the need for users to juggle separate wallets, bridges, or platforms. Its cross-chain infrastructure aggregates liquidity from diverse sources and routes transactions using split-routing algorithms designed to achieve CEX-comparable prices, serving as a practical bridge between Solana-native assets and the broader DeFi liquidity across EVM and Move-VM chains. The platform's developer APIs expose swap routing, liquidity aggregation, and cross-chain bridging capabilities, enabling other teams to embed multi-chain functionality in their own applications. The Kana Paymaster service sponsors gas fees on behalf of users on Move-VM chains, removing the requirement to hold native tokens — a key friction point in cross-chain UX. At its peak, the Paymaster reached 3.7 million monthly active users and processed 396 million sponsored transactions in total, representing approximately 30% of total Aptos network activity. Over $10 billion in cumulative cross-chain trading volume across all products reflects the scale of activity the platform has enabled.

ICPay provides a unified payment API spanning three blockchain ecosystems: Solana, Base (EVM), and Internet Computer Protocol. A single REST endpoint abstracts chain-specific transaction construction, allowing developers to accept payments across all three networks through one integration and one SDK. Supported wallets reflect each native ecosystem: Phantom and Backpack for Solana, MetaMask and Coinbase Wallet for EVM, and Plug, Internet Identity, Oisy, and NFID for Internet Computer. The cross-chain scope extends to agentic payment standards. ICPay X402 implementation allows AI agents to pay for resources across Internet Computer, EVM, and Solana using a unified sign-and-settle flow triggered by HTTP 402 responses. Token identifiers use chain-prefixed shortcodes such as sol_usdc, base_usdc, and ic_icp, and the token list is fetched dynamically from the API so new assets can be added across any supported chain without SDK changes.

Myaza's B2B infrastructure API is a production-grade multi-chain payment layer that lets African businesses and fintechs accept stablecoin payments across Solana, Ethereum, Polygon, TRON, and Stellar from a single unified platform. The API supports programmatic wallet generation and management, real-time address monitoring via webhook notifications, and cross-chain asset bridging via Wormhole — giving developers the tools to build financial applications that span multiple blockchain ecosystems without requiring deep expertise in each network's mechanics. For Solana-focused builders, Myaza leverages the network's high throughput, sub-second finality, and low transaction costs to handle the high-frequency, small-value transfers typical of African remittances and micro-merchant commerce. Solana is explicitly listed among the supported chains for wallet creation, payment acceptance, and stablecoin receipt, and as USDC adoption on Solana continues to grow — making it one of the highest-volume stablecoin settlement networks globally — Myaza's multi-chain architecture positions developers to route African financial corridors through whichever network best serves a given use case at any moment.

Unhosted abstracts cross-chain complexity into a single self-custodial wallet interface, supporting over 100 blockchains — including Solana, Ethereum, Bitcoin, Arbitrum, Polygon, Optimism, Avalanche, and Polkadot. The platform handles bridging automatically behind the scenes through LI.FI routing, eliminating the need for users to manually select bridges or manage native gas on each network. Gas payments are abstracted further, allowing users to pay transaction fees in any token they hold rather than sourcing the native asset for each chain. The wallet covers more than 10 million cryptocurrencies and 600 million NFTs across its supported networks, consolidating multi-chain portfolios into one interface. For Solana users holding assets across multiple ecosystems, Unhosted aggregates Solana balances alongside EVM portfolios without requiring separate chain-specific tooling or manual bridge coordination, making it a practical hub for multi-chain asset management from a single self-custodial account.

SwapBee's cross-chain capability is built on integrations with LI.FI and Bungee, two bridge aggregators that compare multiple bridging protocols to find efficient routes between networks. LI.FI connects more than 20 bridges and DEX aggregators — including Uniswap, 1inch, Stargate, and Across — across 60+ blockchains and has processed over $80 billion in volume across 100 million transactions, while Bungee, powered by Socket, adds an additional layer of bridge comparison. Together these integrations allow users to swap assets between Solana and EVM-compatible networks without manually operating a bridge or interacting with any individual bridging protocol. Solana is supported natively on SwapBee, with users able to swap SOL, USDC on Solana, USDT on Solana, and other Solana-based tokens into assets on other networks, or receive Solana assets as the output of cross-chain swaps originating elsewhere. The LI.FI and Bungee integrations are the primary mechanisms enabling Solana-to-EVM and EVM-to-Solana routing, surfaced as example pairs on SwapBee's main interface. Because SwapBee never holds user funds, cross-chain counterparty risk is concentrated in the bridge and DEX aggregator layer rather than in the aggregator itself, providing users with a clear picture of where risks lie across each transaction.

reply.cash aggregates liquidity across 31 blockchains and supports 181 tokens, making it one of the broadest multichain platforms available for stablecoin-based cross-border payments. The platform handles cross-chain bridging natively: a user holding assets on Base can route through Solana before disbursing to an African mobile money recipient — all within a single flow that completes in under 60 seconds. Supported chains span Solana, Ethereum, Polygon, Arbitrum, Base, Optimism, and Bitcoin, covering virtually the full landscape of active stablecoin liquidity. Cross-chain transfers are managed non-custodially: wallet connections through Phantom, Solflare, MetaMask, Brave, or other supported wallets remain user-controlled throughout, and no account or login is required to initiate a transfer. The platform's primary innovation lies in completing the last-mile step that most cross-chain bridges leave unfinished — converting arrived assets into local fiat and disbursing directly to mobile money operators or bank accounts. This end-to-end design collapses what would otherwise require multiple separate services into a single seamless flow.

Fuse Bridge enables asset transfers across Ethereum, BNB Chain, Arbitrum, and Polygon, keeping the Fuse network liquid within the broader EVM ecosystem. The full EVM compatibility means that smart contracts and decentralized applications built for other major EVM chains can be deployed on Fuse without modification, lowering friction for cross-chain migration. Wrapped versions of FUSE (wFUSE) are available on BNB Chain, Arbitrum, and Polygon, extending the native token reach across the EVM landscape. The cross-chain infrastructure supports the payments-first mission by allowing users and businesses to move assets into the network from established chains while maintaining access to liquidity elsewhere. The FUSE token is listed on Binance, Huobi, and KuCoin, and the combination of bridge infrastructure and exchange listings makes the network accessible to a broad user base. This interoperability layer is foundational to the strategy of positioning Fuse as a consumer-facing chain within the wider EVM ecosystem rather than an isolated network.

FxWallet supports more than 80 public blockchains from a single mobile interface, covering Solana, Bitcoin, Ethereum, BNB Chain, Tron, XRP, and Ethereum Layer 2 networks including Arbitrum, Optimism, Base, Polygon, Linea, and Mantle, along with newer chains such as Berachain and Aleo. Token standard coverage spans ERC-20, ERC-721, TRC-20, and BRC-20, giving users access to fungible tokens, NFTs, and Bitcoin Ordinals across supported chains. The wallet offers single-chain and cross-chain swap functionality from within the mobile app. Cross-chain swaps route through MEV-protected paths to reduce sandwich-attack and frontrunning exposure. An integrated DApp browser covering more than 200 decentralized applications lets users interact with protocols on any supported chain without leaving the wallet interface.

Baltex bridges Solana with other blockchain networks, enabling users to move assets across chains as part of its cross-chain transfer infrastructure. The platform supports users who need to convert or transfer tokens between ecosystems, removing the need to interact with multiple bridge protocols independently and providing a more streamlined approach to managing assets across different blockchain environments. This cross-chain capability is integrated into Baltex's broader trading interface, allowing participants on Solana to access liquidity and assets from other networks in a single workflow. The platform's approach focuses on reducing friction for users navigating a multi-chain environment, supporting the interoperability that underpins Solana's growing role as a hub for cross-ecosystem DeFi activity.

Nabox allows one cryptographic key pair to manage assets and sign transactions across more than 100 blockchains simultaneously, spanning Ethereum, BNB Chain, Polygon, Arbitrum, Optimism, zkSync, Solana, TRON, and others. The NerveNetwork cross-chain relay layer, developed by the NULS ecosystem, underpins these capabilities, with NerveBridge enabling cross-chain transfers exposed directly through the wallet. On Solana, Nabox handles SOL balances and SPL token queries, with Solana NFT display support in active development. SwapBox routes trades across chains touching Solana liquidity pools, and WalletConnect plus MetaMask injection ensure broad DApp compatibility across the EVM and multi-chain ecosystem.

Cosmostation offers non-custodial wallet software spanning mobile and browser platforms, supporting more than 80 blockchain networks from a single interface. The Cosmostation Wallet for iOS and Android and the Cosmostation Extension for Chrome both give users full self-custody of private keys while enabling staking management, IBC token transfers, and interactions with decentralized applications across supported chains. The breadth of network support is a direct response to the fragmented nature of the Cosmos IBC ecosystem, where managing assets across dozens of interconnected zones has historically required multiple tools. Governance participation is a prominent feature of the wallet products: Cosmostation surfaces active on-chain proposals from networks where the user holds delegated stake, enabling delegators to vote directly without leaving the wallet. This positions Cosmostation's wallet offering as a cross-chain interface for both asset management and network participation, reflecting the company's dual role as both a validator and a retail-facing infrastructure provider across the interchain.
