Cross-Chain Solutions

Cross-chain execution is central to Azura's architecture, with the platform supporting token swaps across Solana, Ethereum, Base, Arbitrum, and additional EVM networks through a single non-custodial interface. The intent-based engine handles bridging and routing automatically, eliminating the need for users to manage wrapped tokens or navigate separate bridge interfaces for each supported network. From the user's perspective, a cross-chain swap is a single transaction with no intermediate steps requiring additional wallet confirmations or protocol-specific knowledge. The architecture is designed to extend to additional chains without altering the user-facing workflow, treating cross-chain movement as a standard feature of any trade rather than a specialized operation that demands separate tooling.

Codex FX includes a multi-chain bridge connecting Solana to Ethereum and Tron, enabling institutions to move USDC, USDT, and PYUSD across chains without leaving stablecoin rails. This bridge is embedded within a B2B payments and FX settlement product rather than operating as a standalone protocol, giving it an institutional focus on compliant cross-border transfer rather than speculative bridging. The underlying Codex Chain is EVM-equivalent and settles on Ethereum L1, accepting USDC as its native gas token to eliminate ETH-holding requirements for stablecoin operators. Base-layer compliance primitives including sanctions screening, account-level freezing, and audit-ready transaction memos apply across all chain activity, making Codex FX one of the few institutionally focused cross-chain stablecoin corridors with a direct Solana integration.

Mayan is a cross-chain swap and bridge protocol built on Solana that uses competitive on-chain auctions to route assets between blockchains at optimized prices. Rather than relying on shared liquidity pools with fixed pricing, Mayan's intent-based architecture lets competing solvers fill user orders, delivering market-rate pricing at execution. The protocol connects Solana, Ethereum, BNB Chain, Base, Arbitrum, Optimism, Sui, Monad, HyperEVM, and additional networks. Since launching in February 2022, Mayan has processed over $18 billion in cumulative volume across more than 8 million swaps and served more than 3 million unique wallets. Its routing infrastructure is embedded in Phantom, MetaMask, OKX Wallet, and Trust Wallet. Solana serves as the auction and coordination layer for all cross-chain order matching, making Mayan a foundational piece of Solana's multi-chain transfer infrastructure.

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.

Orbiter Finance is a decentralized cross-chain bridge that transfers native assets across more than 80 blockchain networks—including Solana—without issuing wrapped tokens, completing transfers in 10 to 20 seconds. The bridge operates through a maker/taker liquidity model where users send funds to whitelisted liquidity providers called Makers, who hold pre-positioned assets on destination chains and immediately release matching funds from their own addresses. Since launching on mainnet in 2021, Orbiter has processed more than 35 million transactions representing over $28 billion in cumulative volume. The bridge supports Ethereum L2s, Bitcoin-native chains, SolanaVM networks, StarkNet, Sui, TON, Tron, and others, with ETH, USDC, USDT, DAI, and WBTC as core bridgeable assets. An open REST API and a JavaScript SDK with native Solana transaction support allow DeFi protocols and wallet interfaces to integrate Orbiter as a programmable cross-chain liquidity layer.

Rango functions as a cross-chain aggregation and routing layer, connecting more than 80 blockchains spanning every major virtual machine type. Supported ecosystems include EVM networks such as Ethereum, Arbitrum, and Base, as well as Solana, Bitcoin via UTXO-native routing, 15+ Cosmos chains, and non-EVM L1s including Aptos, Sui, TON, and XRPL. An intent protocol layer coordinates a solver network for cross-chain transfers, improving settlement times on routes that support it. Cross-chain routes on Rango may combine a DEX swap on the source chain, a bridge transfer through one of 120+ integrated bridge adapters, and a DEX swap on the destination chain, all managed as a single user action. Settlement times vary by bridge type: intent-based bridges settle in 30 seconds to 2 minutes, wrapped-asset bridges in 2–7 minutes, and canonical chain bridges in 10–30 minutes, with expected completion time surfaced at the quoting stage. Gasless execution is available on Solana and EVM chains, enabling users to bridge assets to a new chain without holding native gas tokens.

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.

1inch operates across 13 or more chains, with its 1inch Business developer API suite supporting 16 or more networks under a single integration covering swaps, order books, token pricing, balances, and cross-chain operations. Cross-chain swaps connecting Solana to ten additional blockchains are on the product roadmap, which would position Solana as a routing hub for multi-chain users rather than a silo. Pay-per-call billing for the Business API is available via the x402 protocol using USDC on Base. The platform's cross-chain scope is a key differentiator on Solana, where 1inch competes against native aggregators by offering connectivity to EVM chains through the same interface and API used elsewhere. The Fusion protocol's resolver network extends across all supported chains, giving users consistent gasless swap execution whether routing through Solana, Ethereum, or other supported networks.

PayGrid's chain-abstracted API supports stablecoin payment clearing across Solana and five EVM-compatible chains from a single interface. The corridor concept abstracts away the underlying settlement network, so a USDC payment routes through whichever chain offers the best execution at a given moment. PSPs and liquidity providers avoid managing separate per-chain integrations or holding native gas tokens, since gas abstraction is built into the protocol. The technical stack includes Grid, an open-source payment intent protocol written in Solidity under AGPL-3.0, and the Paygrid SDK, a TypeScript library under Apache-2.0 providing the chain-abstracted payment stack for developers. The developer-facing API covers four sequential stages: corridor routing and price discovery, payment intent authorization, submission through the Clearing Gateway, and reconciliation status tracking. Delegated payment intent signing means the system works with deposit accounts, self-custodial wallets, smart contracts, and embedded wallets.

Blockend builds cross-chain liquidity infrastructure that lets dApp developers embed multi-chain swap capabilities with a single npm package. Its COMPASS aggregator consolidates DEXs, bridges, RFQ systems, and intent protocols across 80-plus chains—EVM networks, Solana, Cosmos, and Tron—into one routing interface. The engine scores each available path by output, gas cost, speed, and provider reliability to select the best route automatically. In development, LEX (Liquidity Exchange) brings an intent settlement protocol to the Solana Virtual Machine. Rather than deploying contracts on each supported chain, LEX centralizes escrow, validation, and settlement on a purpose-built SVM chain. New chains integrate without per-chain contracts, and the SVM's 50-millisecond block times allow settlement in minutes compared to the 24–48 hours typical of optimistic bridge designs.

Omnity Network is a cross-chain infrastructure platform that routes Bitcoin native assets — BTC, Runes, and BRC20 tokens — across more than 18 blockchains including Solana, Ethereum, TON, Sui, and Osmosis. Its core product, Omnity Hub, is a canister deployed on the Internet Computer Protocol that uses chain-key cryptography to hold and transmit native BTC on the Bitcoin mainnet without wrapping assets or relying on custodial bridges. Omnity Hub operates a hub-and-spoke model distinguishing settlement chains, where finality is anchored, from execution chains, where applications consume routed assets. Threshold signature schemes managed by ICP subnets replace third-party bridge contracts, and verifiable light clients provide state proofs across connected networks. Solana participates as both a settlement and execution chain, enabling Solana applications to receive BTC, Runes, and BRC20 assets as native SPL tokens backed on-chain Bitcoin. Projects including odin.fun have integrated Omnity Hub to route Bitcoin Runes and BTC cross-chain as of early 2025.

Zynta builds cross-border payment infrastructure that uses Solana, Ethereum, and Stellar as settlement rails to route value between Africa and Europe, replacing correspondent banking intermediaries with blockchain confirmation speeds. Rather than locking clients into a single network, Zynta's multi-chain approach accommodates counterparties across different chain preferences, with Solana serving as the primary high-velocity rail due to its throughput and low transaction costs. The platform handles the full settlement stack: fiat-to-stablecoin conversion, on-chain routing through the network of choice, and fiat conversion on the receiving end. USDC via Circle is the primary stablecoin instrument, and Zynta's Solana integration benefits from the network's role as the dominant platform for USDC liquidity at scale. Settlement completes in under 30 minutes with fees capped at a flat 0.5% on external transfers—contrasting sharply with the multi-day clearing cycles and 5% spreads typical of correspondent banking across the EU-Africa corridor.

Wirex Pay Chain is a modular ZK app chain built on Polygon infrastructure, enabling any non-custodial wallet or DeFi application to issue its own payment card. The chain combines ZK Rollups and Validium for high throughput at low cost, while Account Abstraction allows gasless transactions across EVM-compatible chains. WPAY, the chain native token, governs the network and incentivizes node operators with 20% of total supply and 40% of fee revenue. Wirex multi-chain reach extends to Solana, TRON, and Stellar alongside its Polygon-based Pay Chain. The Solana integration via Crossmint migrated seven million-plus customer wallets to smart wallet infrastructure for regulated fiat-to-stablecoin flows. Separate partnerships with TRON DAO and Ultra Stellar on Soroban deploy native payment rails on each chain, supporting stablecoin accounts, card issuance, and cross-border payouts without relying on bridge-based interoperability.

Terrace connects 13 blockchain networks including Solana, Ethereum, Arbitrum, Optimism, Polygon, Base, BNB Chain, Avalanche, Blast, Bitcoin, Litecoin, and Dogecoin in a single trading and portfolio management interface. Its Pathfinder routing engine can combine liquidity from a Solana DEX pool and a centralized exchange order book within one atomic trade execution, without the user managing bridges or cross-chain transfers separately. Gas costs for on-chain transactions across all supported networks are bundled automatically into each trade. Portfolio tracking spans 12 blockchains and five major centralized exchanges, with balances refreshing every 60 seconds or immediately on trading activity. Solana is supported as a first-class chain, with integrations covering Raydium, Jupiter, and Pump.fun alongside the broader EVM and Bitcoin ecosystem. A synthetic pairs engine handles trades between tokens that lack native pairs on any single venue, routing through intermediate assets across chain boundaries when needed.

MetaMask's 2025 multichain expansion positioned it as a unified gateway for users operating across Ethereum, EVM-compatible networks, Solana, Bitcoin, Monad, and Sei — all within a single wallet interface. Solana support launched on July 8, 2025, as a native integration in both the browser extension and mobile app, bringing MetaMask's 100 million-plus user base into contact with the Solana ecosystem without requiring them to adopt a separate wallet. Multichain account views allow connected applications to interact across multiple networks in a single session, and the same security features that protect Ethereum interactions apply to Solana activity. Cross-chain bridging is built directly into the MetaMask interface, letting users move assets between Solana and other supported networks without relying on third-party bridge interfaces. MetaMask has stated that Solana is "just the start," with additional non-EVM network integrations planned. For Solana projects and developers, MetaMask's cross-chain architecture creates a practical onboarding path that does not require EVM-native users to abandon familiar tools — reducing friction for one of the largest existing audiences in crypto to discover and use Solana-based protocols.

Xverse is a self-custodial Bitcoin wallet that enables Solana users to swap SOL or Solana-based assets directly into BTC through a Changelly-powered integration launched in December 2024. The converted BTC lands in the user's Xverse wallet without a separate bridging step, making the platform a direct off-ramp from Solana onto Bitcoin rails. The Xverse platform covers Bitcoin Layer 1, Lightning, Stacks, Starknet, and Spark, with non-custodial features including stablecoin yield, onchain lending, and privacy-preserving transactions via Starknet zero-knowledge infrastructure. Secret Key Labs raised $9 million from investors including Jump Crypto and Franklin Templeton, and Xverse reported roughly two million users as of mid-2025.

Garden Finance is one of the few protocols enabling trustless native Bitcoin transfers to and from Solana without wrapping. Using Hash Time Locked Contracts and a competitive solver network, swaps settle in under 30 seconds with no custodian ever holding user funds. The protocol supports native BTC swaps across Ethereum, Solana, Base, Arbitrum, BNB Chain, Hyperliquid, Litecoin, Sui, Monad, Starknet, and Tron, covering more than 20 documented conversion routes. Founded in 2023 by former RenBTC core contributors, Garden has facilitated over two billion dollars in total cross-chain swap volume. Garden's architecture eliminates the trust assumptions common in conventional bridge designs — it does not mint wrapped tokens, does not rely on external validator sets, and operates no custodial infrastructure. Smart contracts are deployed as permissionless, immutable code across EVM, Solana, Cairo, Move, and Rust environments. The February 2026 Code4rena competitive audit explicitly covered Garden's Solana smart contracts alongside EVM, Starknet, and Move implementations. Direct wallet integration with Phantom and aggregator partnerships with SwapKit confirm Garden's active role in the Solana cross-chain ecosystem.

Socket Protocol is a chain abstraction and smart-routing layer that connects 50+ blockchains through a single unified API, making it one of the broadest cross-chain asset transfer platforms with active Solana support. Rather than operating its own bridge, Socket aggregates routes above providers such as Across, Stargate, and Hop, evaluating each path in real time based on cost, speed, and security to return the optimal transfer for a given transaction. The protocol has processed over $20 billion in cumulative volume since 2021 and powers integrations for more than 100 protocols, including MetaMask and Coinbase Wallet. Socket's Q1 2026 Solana integration extends the routing network into the largest non-EVM ecosystem, giving Solana-based dApps direct access to EVM liquidity and enabling EVM-native users to route assets to Solana without managing individual bridge integrations. The technical foundation, Modular Order Flow Auctions (MOFA), broadcasts user intents to a competitive marketplace of fulfillment agents who bid to execute transfers, reducing dependence on any single bridge operator and enabling dynamic optimization by price, settlement speed, or risk profile. Socket currently serves over 1 million users and supports 10,000+ tradeable assets alongside 50+ payment methods spanning crypto wallets, credit cards, and local payment rails across 100+ countries.

OneBalance was a chain abstraction settlement layer designed to eliminate the friction of multi-chain crypto by giving users a single unified balance they could spend across 50+ supported blockchains without manual bridging or per-chain gas management. Its architecture centered on Resource Locks — a mechanism that temporarily escrows assets with defined fulfillment conditions and an expiry time, allowing third-party solvers to instantly execute cross-chain transactions on the destination chain without waiting for source-chain finality. This design achieved an average transaction speed of 250ms while preserving self-custody and eliminating double-spend risk for the solvers who fulfilled transactions. The platform described its model as "chain-free Web3," handling all inter-chain complexity invisibly behind a unified user experience. Supported EVM chains included Ethereum, Arbitrum, Optimism, Base, Polygon, Linea, Avalanche, and BNB Chain. Solana support launched in Q3 2025 and was integrated natively without the ERC-4337 proxy account layer required on EVM networks. Bitcoin was also added, with Resource Locks enabling near-instant BTC-to-EVM swaps despite Bitcoin's slow block finality. At its operational peak, OneBalance processed over $3 billion in settled cross-chain volume with reported 99.99% uptime. Founded by former Flashbots co-founders and backed by Blockchain Capital, Cyber Fund, and Binance Labs, the project raised $25 million before deprecating its API in May 2026 and shutting down entirely by June 2026.

KyberSwap enables cross-chain asset transfers across 26 blockchain networks in a single interface, including Solana, Bitcoin, Near, Ethereum, BNB Chain, Arbitrum, Base, Polygon, Avalanche, Berachain, and Mantle. Solana support was added in July 2025, extending cross-chain routing into the non-EVM ecosystem. Users can move assets such as SOL and USDC to other networks — or bring EVM assets onto Solana — without leaving the KyberSwap dashboard. A proprietary cross-chain solution, KyberCross, is planned as a future release that will use KyberSwap's native aggregator for each swap leg. The protocol's aggregator-first architecture means cross-chain flows leverage the best available liquidity on each leg of the route rather than relying on a single bridge mechanism. With over 420 liquidity sources integrated across the 26 supported networks, KyberSwap connects Solana's DEX ecosystem to the broader multi-chain DeFi landscape. The Smart Settlement upgrade (May 2026) further improves cross-chain execution quality through smarter on-chain path selection at the execution layer.

AEON's settlement architecture spans BNB Chain, Solana, TON, TRON, Stellar, Algorand, and EVM-compatible networks through a three-layer design. The network layer routes payment requests through master nodes that verify off-chain information and match it with on-chain activity. The execution layer uses a Delegated Proof of Stake mechanism, with cross-chain verification handled via light clients on each supported blockchain. The protocol's adaptive finality model adjusts confirmation requirements to each network's individual security profile rather than applying a single rule. Node access is staked: master nodes require a minimum of 1 million AEON tokens; execution validators require 100,000. AEON's $8 million pre-seed round, led by YZi Labs with IDG Capital and HashKey Capital, is targeted at expanding this multi-chain settlement layer specifically for agentic commerce use cases.

SpaceGate is Coin98's dedicated cross-chain bridge, handling asset transfers across Ethereum, BNB Chain, Solana, Polygon, and Viction. The SwapX feature builds on this by consolidating DEX aggregation and cross-chain bridging in one interface, routing across ten blockchains including Solana, BNB Chain, Sui, and Base through 17 connected DEX aggregators. Coin98 has onboarded 26 new blockchains through 2025, bringing total supported networks to more than 140 accessible from a single wallet. The Coin98 Adapter npm library packages this multi-chain engine for developers, supporting 33 EVM-compatible chains alongside non-EVM networks with a built-in connection modal. Recent chain integrations include Concordium, an ID-integrated L1 blockchain, and ADI Chain for payment and real-world asset applications. Coin98 Perps extends the cross-chain reach further by allowing self-custodial perpetual futures trading across crypto assets, tokenized equities, and commodities with up to 10x leverage without leaving the wallet. The March 2026 Perps Arena 2 trading competition drew 562 participants and 3.23 million dollars in trading volume, placing Coin98 in Hyperliquid's top 12 by user count. By June 2026 the platform had listed 16 additional markets covering stocks such as ASML, IBM, DELL, and QCOM.

ShapeShift provides native cross-chain asset transfers as a core feature of its multichain interface, supporting movement across 48-plus blockchains without requiring users to leave the platform or interact with multiple separate bridges. Its integration with THORChain enables direct swaps of native Bitcoin, Ethereum, Avalanche, and other assets without relying on wrapped token representations, preserving true asset ownership throughout the transfer. THORChain Streaming Swaps reduce price impact on large cross-chain trades by splitting them into smaller sequential segments executed at optimal intervals. The platform's Jupiter integration extends this cross-chain reach to Solana, letting users move assets between Solana and 15 other chains through a single non-custodial interface. A dedicated self-custodial Solana wallet and a MetaMask Snap that adds multichain account management across 11 networks further lower the barrier for users in different wallet ecosystems to access ShapeShift's cross-chain routing and bridging capabilities.

Mesh supports payment and settlement flows across 24+ blockchain networks, including Solana, Ethereum, Base, Polygon, Stellar, Tron, WorldChain, and Tempo, functioning as a chain-agnostic connectivity layer. The platform connects over 300 wallets and exchanges into a single integration point, handling chain routing and asset conversion internally so businesses do not manage per-chain infrastructure. Strategic infrastructure partnerships include Paxos (December 2025), Ripple (August 2025), and Tempo, a payments-native Layer 1 incubated by Stripe and Paradigm added to the supported chain set in 2026. SmartFunding, Mesh's proprietary orchestration engine, enables cross-chain payment flows where a buyer pays in any supported asset from any originating chain while the merchant receives settlement in a preferred stablecoin regardless of which network processed the source transaction. This cross-chain abstraction extends to wallet and exchange integrations with MetaMask, Coinbase, Binance, and Revolut, reaching over 900 million users across those platforms. Solana is a supported payment source and settlement destination for USDC within the network.

Tatum supports more than 130 blockchain networks through a single unified API layer, encompassing established chains such as Solana, Ethereum, Bitcoin, Polygon, Arbitrum, Base, BNB Smart Chain, and Celo alongside dozens of emerging L1s and L2s. Its Blockchain Data API normalizes chain data into a consistent schema, so developers can query wallet balances, token holdings, transaction histories, and DeFi positions using a single interface regardless of the underlying chain. This cross-chain design allows small development teams to build multi-chain applications without maintaining separate integrations, indexers, or RPC connections for each supported network. Tatum holds AICPA SOC 2 and ISO 27001 security certifications and counts Binance, Celo, and Zengo among its enterprise customers, positioning it as production-grade infrastructure for applications that span multiple blockchain ecosystems.

Plume's cross-chain deployment infrastructure, SkyLink, extends the platform's yield vault framework to 16 blockchain networks including Solana, Avalanche, BNB Chain, Injective, Movement, and Zircuit. Rather than requiring users to bridge assets to the Plume network, SkyLink surfaces yield-bearing vault tokens as native assets on destination chains, making institutional RWA yields accessible within those ecosystems' existing DeFi tooling without a chain migration. The most developed cross-chain implementation is Nest Vaults on Solana, where five products — nBASIS, nOPAL, nTBILL, nWisdom, and nAlpha — launched in December 2025. Solana users deposit stablecoins and receive liquid vault tokens that remain usable across Solana DeFi applications or are redeemable at any time. This made Plume one of the first RWA protocols to deliver compliant institutional yields directly to Solana users at the distribution layer, with Plume handling tokenization, compliance, and asset custody on its own chain while surfacing yield outputs as composable Solana-native tokens.

Transfero deploys BRZ, ARZ, and CLZ across more than a dozen blockchains using Wormhole's Native Token Transfers as its exclusive interoperability layer. Unlike wrapped bridges, NTT preserves each token's native supply controls, upgrade authority, and access lists on every chain. Supported networks include Ethereum, BNB Chain, Polygon, Avalanche, Algorand, Stellar, Base, Arbitrum, Optimism, Celo, and Solana. Solana hosts roughly 200 million BRZ, the largest single-chain share of 276.9 million total. Beyond stablecoins, Transfero's unified API connects Pix payments, fiat on-ramps and off-ramps, OTC liquidity, and multi-currency accounts in one integration. This lets fintechs access cross-chain settlement without managing separate per-network connections. On Solana, this infrastructure underpins the first BRL-denominated credit market, launched by Loopscale in March 2026 using BRZ and tokenized Brazilian treasury bonds.

Uniramp's Hybrid-Ramp Engine incorporates decentralized routes alongside centralized providers, tapping DEX aggregators and cross-chain bridge protocols to find the most efficient path for each transaction. Protocols in the decentralized routing layer include Uniswap, 0x, cBridge, Aave, Balancer, Apeswap, Bakeryswap, and Bancor, among others. This cross-chain reach means users can access on-chain assets on Solana without being limited to routes that any single centralized provider supports. The engine evaluates centralized and decentralized paths simultaneously for every transaction, selecting the combination with the lowest all-inclusive cost rather than the lowest stated fee percentage. Spread and network fees are factored into the calculation before a route is committed. This multi-network architecture allows Uniramp to serve markets where centralized providers are unavailable or uncompetitive, filling gaps through DeFi liquidity that would otherwise block fiat access in those regions.

BoomFi abstracts multi-chain settlement complexity behind a single commercial-grade API, supporting merchant payments across Ethereum, Polygon, BNB Chain, Solana, Arbitrum, and Tron. Its non-custodial architecture routes transactions through trustless smart contracts and automated payment processors, handling real-time conversion and settlement into the merchant's preferred currency — fiat or stablecoin — without BoomFi ever holding customer or merchant funds. Solana is highlighted for its low transaction costs and fast finality, making it particularly well-suited to consumer payment contexts where confirmation speed and per-transaction fees affect end-user experience. Merchants need no individual chain integrations; BoomFi manages chain-side mechanics, fiat conversion, AML screening, and bank settlement as a unified cross-chain managed service.

Squid Router is cross-chain routing infrastructure connecting more than 100 blockchains, enabling single-transaction token swaps across the full multi-chain landscape. The platform has processed over $6 billion in cumulative volume, serving one million users and embedding its routing engine into 1,000-plus applications including MetaMask, Ledger, and Keplr. Solana is a first-class destination, supported through a Chainflip integration delivering native SOL routing rather than wrapped equivalents. Rather than relying on a single bridge, Squid orchestrates across multiple transport protocols including Axelar GMP, Circle's CCTP, IBC, Chainflip, and LayerZero. Its intent-based Squid Intents engine runs real-time solver auctions where professional market makers compete on price, with Trusted Execution Environments coordinating offchain computation and settlement completing in under five seconds.

The Wallet as a Service module supports deposit address generation and blockchain transfers across 14 networks, making multi-chain crypto balances accessible for card spend without bridging to a single chain first. Supported assets include native USDC and USDT on Solana, Ethereum, Avalanche, Base, Arbitrum, Polygon, Optimism, TRON, and TON. This network coverage lets Web3 businesses serve users regardless of which chain holds their stablecoin balances. The cross-chain layer feeds directly into the card issuance pipeline: deposits arrive on-chain, pass through KYT screening, convert to spendable fiat via CryptoConnect, and route to the card layer within a single API integration. For Solana-based applications, native USDC and USDT can flow directly to physical or virtual cards accepted wherever Visa and Mastercard are honored, without an intermediate bridging step.

Flexa is a multi-chain payments infrastructure layer that accepts assets from more than a dozen blockchains at physical retail points of sale, including a broad range of Solana-native tokens such as SOL, USDC on Solana, BONK, WIF (dogwifhat), DRIFT, ORCA, and RENDER. The platform manages cross-chain complexity through Flexa Capacity, an onchain collateral system denominated in AMP that locks collateral in real time when a payment processes and releases it once the underlying transaction settles on its native blockchain. Capacity v3, deployed in July 2025, stores collateral in an audited Anvil Vault contract with predictable 12-to-24-hour unlock windows. By treating multi-chain token acceptance as a native design principle, Flexa allows merchants to accept any supported asset through a single integration, and Solana token holders to spend at participating retailers without routing through an exchange first.

Particle Network is built specifically to solve Web3 chain fragmentation through its Universal Accounts system, giving users a single address, an aggregated balance, and unified gas across more than 65 blockchains including Solana and all major EVM networks. The ERC-4337 standard underpins Universal Accounts, coordinated by Particle Network's own settlement chain — the Particle Chain — which launched in September 2025 with more than 20 validators using Celestia, Avail, and NEAR DA for data availability. Universal Liquidity routes funds atomically across chains via a Decentralized Messaging Network, while Universal Gas enables fee payment in any token settled in PARTI on the Particle Chain. EIP-7702 support added in 2026 allows existing wallets to upgrade without changing their address. As of Q1 2025, the network had reached 110,900 Universal Accounts with 557.6 percent quarter-over-quarter growth and 27,100 daily transactions representing 806.5 percent QoQ growth.

Portal wallet infrastructure is deliberately chain-neutral, built on TSS MPC with both ECDSA and EdDSA signature support so the same platform can serve blockchains with fundamentally different cryptographic requirements from a single codebase. The platform currently covers more than 100 networks including Solana, Bitcoin, Ethereum, and EVM-compatible chains, meaning a developer integrating Portal SDK gains wallet and signing functionality across all supported networks through a single integration. This architecture means businesses do not need to maintain separate wallet providers for each blockchain they operate on, and users hold assets across chains within a unified embedded wallet experience. Stablecoin transfers, SPL token transactions on Solana, and EVM-based interactions all route through the same underlying MPC infrastructure, giving multi-chain applications a consistent security and compliance baseline.

Borderless operates as a pure orchestration and data layer across multiple blockchain networks, supporting settlement in USDC, USDT, and RLUSD on Ethereum, Solana, Polygon, Base, Tron, and XRPL. The platform abstracts the complexity of multi-chain settlement behind a single API and standardized schema, so fintech companies and financial institutions can access whichever chain and asset combination a given provider has the best liquidity for without building or maintaining individual chain integrations. The multi-chain architecture underpins the routing intelligence layer, which continuously tracks provider reliability scores and execution benchmarks across the network and improves as transaction data accumulates. By treating chain selection as a routing variable rather than a fixed constraint, Borderless gives clients flexibility across settlement rails while research confirms that the real pricing opportunity—spreads of up to 703 basis points—lies in provider selection rather than chain or stablecoin selection.

Alfred Pay operates multi-chain settlement infrastructure that accepts and delivers USDC and USDT across Solana, Ethereum, Base, Arbitrum, Polygon, Tron, and Stellar, abstracting cross-chain complexity behind a single REST API. Its Alfred Payment Manager (APM) maintains rotating blockchain addresses across all supported networks, automatically detecting inbound transfers and triggering the corresponding fiat delivery through Latin America's local payment rails. The cross-chain design means businesses on any supported network — a Solana wallet, an Ethereum DeFi protocol, or a Tron exchange — access the same LatAm banking rails without managing separate integrations per chain. For Solana specifically, alfred accepts USDC on Solana for settlement and joined the Circle Payments Network as a Beneficiary Financial Institution, formalising the Solana USDC-to-fiat pathway for PIX in Brazil and SPEI in Mexico.

Rayls connects to more than 120 public blockchain networks through a LayerZero integration, allowing banks operating on private permissioned subnets to move stablecoins, CBDCs, and tokenized deposits to Solana, Ethereum, TON, and other chains in real time. The Rayls Enigma protocol handles cross-border FX settlement by converting tokenized deposits to stablecoins and back in seconds, eliminating the liquidity gap between institutional permissioned systems and public on-chain markets. Parfin's FX desk was migrating approximately $400 million in monthly foreign exchange volume onto Rayls beginning Q3 2026, with institutional flows routed via the LayerZero bridge potentially reaching Solana. Mastercard's inclusion of Rayls alongside Solana, Polygon, Ripple, and Stellar in its Crypto Partner Program ties both ecosystems together as recognized institutional settlement infrastructure.

Butter Network is an omnichain hub connecting over 20 blockchains — including Solana, Bitcoin, Ethereum, BNB Chain, TRON, and multiple EVM Layer 2 networks — through a product layer built on MAP Protocol relay chain. Cross-chain message passing is secured through a hybrid model combining ZK light client verification with multi-signature oracle validation, where ZK-SNARKs verify block headers without replaying full validator computations. Solana is integrated at a dedicated v3.1 mainnet contract, enabling users to transfer assets between the Solana ecosystem and any connected chain in a single transaction. Butter competes in the cross-chain segment alongside LayerZero, Wormhole, and Stargate, with non-EVM chain coverage including Bitcoin and TRON as its primary technical differentiator; bridge fees are paid in native gas tokens with no separate protocol token required.

HIFI's cross-chain settlement capability is built on Circle's Cross-Chain Transfer Protocol (CCTP), which burns USDC on the source chain and mints it natively on the destination chain — eliminating the slippage and wrapped-token overhead associated with conventional bridge-style transfers. Developers can configure cross-chain flows in three modes: bridge-only, full end-to-end payout (automated bridge plus Circle Payments Network settlement to local-currency accounts), or bridge-then-payout with custom business logic inserted between steps for additional processing. On Solana specifically, HIFI supports native multi-chain operations as part of the Circle Payments Network integration, making Solana one of three CPN-supported settlement chains. This gives developers a single API capable of accepting funds in fiat or on any supported EVM chain and settling to Solana — or originating on Solana and settling to fiat in 60-plus countries — without managing individual bridge contracts, wrapped-token liquidity pools, or chain-specific custody arrangements. The CCTP-based architecture also means transfers carry no bridge slippage, a meaningful advantage for high-volume payment flows where spread costs accumulate.

Kima Network is a cross-chain settlement protocol that moves assets between blockchains without bridges, wrapped tokens, or smart contracts on the source or destination chains. Built on the Cosmos SDK with its own proof-of-stake blockchain, it maintains native liquidity pools on each integrated Layer-1 network — including Ethereum, Polygon, Solana, and Bitcoin. When a transfer is initiated, light clients detect the deposit and a rotating committee of Wardens inside Intel SGX Trusted Execution Environments applies threshold signatures to authorize the corresponding release from the destination pool. Recipients always receive the real native asset sitting in the destination pool, never a synthetic wrapped token. The LIMA algorithm dynamically adjusts fee rates and liquidity provider incentives based on pool utilization across all integrated chains, preventing one-directional flow from draining any single pool. Solana is an explicitly supported network, meaning Solana-ecosystem assets can reach any other integrated chain without ever entering wrapped-token form.

Panora Flows is a bridge aggregation product that combines cross-chain routing with DEX execution in a single operation. Users select a source asset on any of more than ten supported blockchains — including Solana, Ethereum, and Polygon — and specify a destination token on Aptos; Flows scans available bridges and liquidity sources to find the most efficient path and executes the full move-and-swap, delivering the target Aptos token to the user's wallet without manual multi-step bridging. This consolidated approach eliminates the typical workflow of separately interacting with a bridge, waiting for confirmation, and then navigating to a DEX to complete the swap. By compressing those steps into a single operation, Flows reduces operational complexity and the number of failure points in cross-chain asset transfers. The product supports users entering Aptos from Solana and other major chains, providing a streamlined on-ramp for cross-chain participants.

Stargate is a composable cross-chain liquidity transport protocol enabling native asset transfers — USDC, USDT, ETH, and BTC — across more than 80 blockchains without wrapping. Unlike bridges that fragment liquidity through synthetic wrapped tokens, Stargate deploys unified liquidity pools on each supported network and uses its Delta algorithm to reallocate credits dynamically. Users receive canonical assets with instant guaranteed finality, and since launch in March 2022, the protocol has settled over $65 billion in on-chain transfers across Ethereum, Arbitrum, Solana, Base, Avalanche, Polygon, and BNB Chain. Stargate V2 introduced an AI Planning Module that redistributes credits automatically across Taxi Mode for immediate composable settlement and Bus Mode for bundled lower-cost transfers. Solana support arrived through LayerZero V2 and the OFT standard, enabling tokens like PENGU to move between Solana and 80+ connected chains without a dedicated native-asset pool. The protocol continues to expand network coverage, recently adding NEAR Intents and IOTA Mainnet as supported chains.

Kana Labs built a multi-chain aggregation layer spanning nine blockchains — Solana, Aptos, Sui, Ethereum, Polygon, BNB Chain, Arbitrum, and Avalanche — unifying both EVM and non-EVM chains under a single routing interface. The cross-chain bridge aggregation component sources the best path and rate across each leg of a multi-chain swap, abstracting away the complexity of moving assets between networks with different consensus mechanisms and token standards. This expansion followed the platform's Solana origins: as Aptos, Sui, and EVM chains attracted fresh capital and scattered liquidity further, Kana Labs extended its aggregation scope rather than constraining users to a single chain. The combined DEX and bridge aggregation has processed over $8 billion in volume across supported networks. Supporting the cross-chain user experience is Kana Paymaster, a gas sponsorship layer that eliminates the need for traders to hold native gas tokens on each chain they interact with. Rather than requiring users to manage ETH on Arbitrum, SOL on Solana, and APT on Aptos separately, the Paymaster infrastructure absorbs transaction costs — processing over 340 million transactions and reaching close to one million daily sponsored transactions for more than 100,000 users. This infrastructure is also available to third-party developers through the Kana Labs Build SDK, which exposes cross-chain bridging APIs and the Paymaster layer for embedding in external applications. Under the Xyra Labs rebrand in late 2025, the cross-chain routing and bridge aggregation capabilities remain active beneath the trading interface at xyra.trade.

Junction integrates one-click bridging across more than 30 blockchains as a core feature of its unified DeFi interface. The routing engine draws on Circle CCTP, THORChain, Maya Protocol, Chainflip, Socket, and LiFi to identify the optimal transfer path at execution time, covering both EVM chains and UTXO networks such as Bitcoin. Users manage everything from a single interface with self-custody preserved throughout; Solana users can bridge assets to Ethereum, Base, Hyperliquid L1, or Cosmos zones without leaving the platform or switching bridge providers. The Junction API exposes bridging as part of its unified DeFi endpoint, so any application or AI agent can request a cross-chain transfer through a single REST or GraphQL call. Junction's Connector product handles multi-wallet account management across supported ecosystems, reducing the operational overhead of cross-chain activity. Machine-readable discovery files — including /.well-known/agent.json and /.well-known/ai-plugin.json — allow autonomous systems to discover and invoke bridging capabilities without custom integration work, positioning Junction as practical infrastructure for both human users and software agents navigating a fragmented multi-chain environment.

PancakeSwap connected Solana to its Crosschain Swap feature on September 22, 2025, powered by Relay Protocol, which had processed over 55 million cross-chain transactions before the integration launched. Users can swap assets between Solana and six other chains — BNB Chain, Ethereum, Arbitrum, Base, zkSync Era, and Linea — directly within the PancakeSwap interface. Transactions typically settle within a minute, with transparent fee breakdowns separating PancakeSwap's AMM fee from Relay's bridge fee. The Solana integration was the protocol's eleventh blockchain deployment and its first outside the EVM ecosystem, requiring a ground-up reimplementation of its smart contract architecture. The cross-chain feature enables flow in both directions: EVM-chain users can access Solana-native tokens without managing a separate bridging workflow, while Solana users can reach token markets on BNB Chain and Ethereum through the same interface. This positions PancakeSwap as an aggregation layer across chains rather than a chain-specific protocol. Users can also bridge the CAKE governance token to Solana via Stargate, LayerZero, or deBridge. The rollout began with basic token swap functionality in April 2024, followed by full v3 liquidity pool support in July 2025 and cross-chain swaps in September 2025.

xLabs is a core contributor to Wormhole, the interoperability protocol connecting Solana to over 30 blockchains. Their Portal Bridge is the primary user-facing bridge interface for the Wormhole ecosystem, enabling asset transfers and swaps across Solana, Ethereum, Avalanche, Arbitrum, and a growing roster of Layer 2 networks. The company also operates one of the primary CCTP Relayer networks for Circle, processing millions of native USDC burn-and-mint transfers annually across chains without wrapping. xLabs runs Guardian nodes on Wormhole mainnet and testnet — the permissioned validators whose co-signatures enable cross-chain message delivery — alongside over 100 RPC nodes across 35-plus blockchains. Circle recognizes xLabs as both a Bridge App and Bridge SDK provider in its Alliance Directory, reflecting its central role in USDC cross-chain infrastructure on and from Solana.

VIA Labs provides cross-chain asset transfer infrastructure that moves tokens and NFTs between blockchains while preserving their original properties — without minting synthetic representations or relying on bridge intermediaries that lock assets and introduce systemic hack risk. Developers deploy native cross-chain ERC20 tokens that remain semantically consistent across networks, and NFT collections that transfer with full metadata preservation, making them practical for marketplaces and gaming assets that span multiple chains. Unlike wrapped-token bridges, VIA's relay model keeps assets native to each chain rather than generating IOU structures that fragment liquidity. The platform also includes Proto-USD, a cross-chain USDC integration for Avalanche L1s that combines Avalanche's native Interchain Messaging with Circle's Cross-Chain Transfer Protocol, enabling USDC flows from Ethereum, Base, and other CCTP-enabled networks to any Avalanche L1. Solana compatibility for Proto-USD is listed as forthcoming, which would allow VIA Labs' relay layer to bridge USDC between Solana and the broader CCTP ecosystem. Across 130 or more supported public and private blockchains, VIA Labs' approach eliminates the fragmented liquidity and synthetic token structures that characterize most conventional cross-chain bridge solutions.

Synapse Protocol is one of the most widely used cross-chain bridge protocols in DeFi, enabling asset transfers across 24 blockchain networks including Ethereum, Solana, Arbitrum, Optimism, and BNB Chain. With over $15 billion in cumulative bridging volume and more than $100 million in total value locked, it has established itself as a foundational piece of multi-chain infrastructure since its 2021 launch. The protocol employs three distinct bridging mechanisms: stablecoin AMM pools that handle transfers without wrapped token intermediaries, a canonical lock-and-mint model for non-stablecoin assets, and SynapseRFQ, an intent-based system where competitive relayers fulfill cross-chain transfer requests with faster execution and tighter pricing. For Solana users specifically, a dedicated bridge interface at solana.synapseprotocol.com extends Synapse's reach into the Solana ecosystem, enabling direct asset movement between Solana and major EVM-compatible networks. The protocol supports over 50 tokens including USDC, USDT, DAI, ETH, WBTC, and its own synthetic nUSD and nETH assets, giving Solana participants access to deep, battle-tested cross-chain liquidity. Governance of the bridge now falls under the Cortex DAO following a 2025 restructuring, while the infrastructure itself remains fully operational with years of bridge volume behind it.
