Cross-Chain Solutions

MegaYours enables tokens minted on Solana, Ethereum, and other networks to operate across chains without locking assets into bridge contracts. Its Gamma Chain component provides stakeless, bridgeless interoperability: cross-chain transfers work by querying the token's metadata, submitting an init_transfer transaction, and generating an ICCF (Inter-Chain Consensus Framework) cryptographic proof that the destination chain verifies independently. Because assets never leave their native chain, DeFi positions, NFT rarities, and governance rights are never split across wrapped representations. Tokens can continue traveling to additional chains even when the originating application did not preserve metadata on its side, since Yours Protocol always persists metadata internally. This approach directly addresses liquidity fragmentation, a structural problem with conventional bridge architectures, and eliminates the trust assumptions associated with custodial bridge pools.

Cash App's stablecoin transfer feature operates across four blockchain networks: Solana, Ethereum, Polygon, and Arbitrum. Block built the integration with a chain-agnostic architecture, assigning each verified user an on-chain address for every supported network and routing transfers automatically based on the destination address. Users do not need to select a network or manage gas fees; Cash App handles network selection and on-chain execution in the background. Solana was the primary chain Block evaluated during development, selected for its throughput of roughly 2,600 transactions per second, sub-second finality, and average transaction costs under a fraction of a cent. Block has stated publicly that it plans to expand to additional networks and stablecoins as customer demand develops, treating the current four-chain configuration as a starting point. This architecture allows Cash App to serve users across different blockchain ecosystems without requiring any single network preference.

The BRRR protocol (Blockchain Reconciliation and Remittance Record) is Holyheld's open-source modular settlement layer, launched in April 2023 and subsequently spun out as infrastructure available to third-party payment integrators. When a cardholder authorizes a top-up, BRRR detects incoming tokens, performs swaps and cross-chain routing, converts the proceeds to EUR, and reconciles against Mastercard or SEPA rails in under two seconds. The protocol covers EVM chains including Ethereum, Arbitrum, Base, Optimism, and Polygon, as well as non-EVM networks such as Solana and Starknet, with automatic gas abstraction removing the need to hold native tokens on each chain. BRRR powers off-ramp, on-ramp, and multi-call cross-chain orchestration as distinct product lines, and processed over 100 million USD in total volume between its April 2023 launch and December 2024.

Heima Network is a full-stack chain abstraction protocol that gives users a single unified account spanning Ethereum, Solana, BNB Chain, Base, Tron, and Blast, removing the need to manage separate wallets and gas balances per chain. The Omni-Account system deploys EIP-7702 proxy contracts on EVM chains and Substrate proxy accounts elsewhere, letting users authenticate via email, passkeys, or social accounts without managing seed phrases across networks. Heima evolved from Litentry, a Polkadot-ecosystem identity protocol, following a community governance referendum in January 2025. Cross-chain intents are fulfilled by omni-executors inside Trusted Execution Environments that find the optimal path across liquidity pools and bridges, with gas fees sponsored by intent fillers so users never need to hold any chain's native token. A Substrate-based Layer 1 with 500-millisecond block times records all cross-chain activity, providing an auditable trail anchored on-chain even when execution happens off-chain.

Cross-chain capability is central to Sumex's chain-agnostic aggregation model. The platform routes swaps across multiple blockchains through liquidity aggregation infrastructure designed to optimize execution by finding the best available path across supported networks. Private swap functionality is included to reduce exposure to MEV attacks, where bots monitoring the mempool can front-run on-chain trades before they settle. Multi-wallet connectivity allows users to connect self-custody wallets from different blockchain networks alongside centralized exchange accounts within the same interface. Participants with positions distributed across Solana and other networks can track and manage everything from a single dashboard. Sumex is designed as a horizontal aggregation layer rather than a single-chain native application, with infrastructure built to expand support across additional networks as the platform develops.

POTLOCK's smart contracts run on NEAR Protocol, but contributions are accepted from a wide range of networks through NEAR Intents, a cross-chain interoperability protocol that handles native asset swaps and settlement. Supported source chains include Solana, major EVM networks, Bitcoin, Stellar, TON, and Sui. SOL holders can contribute to POTLOCK quadratic rounds directly from their Solana wallets without manually bridging, making POTLOCK one of the few public goods funding platforms accessible natively from the Solana ecosystem. A secondary product, POTLAUNCH, extends the cross-chain design by using Solana as its primary base chain and bridging participation to NEAR via NEAR Intents and Omnibridge. This allows project teams to run token launches with cross-chain participation spanning both ecosystems. For Solana DAOs or foundations wanting to run grant programs, the cross-chain stack enables native SOL contributions while quadratic calculation and settlement occur on NEAR.

Balanced is built around SODAX, a cross-chain execution layer that routes user intents — swaps, loans, deposits — across 13 blockchains without requiring manual bridging, wrapped-token management, or chain-switching mid-transaction. External solvers compete to fill each order at the best available price, then settle the transaction in the background, completing most cross-chain trades in approximately 20 seconds. The architecture draws aggregated liquidity from Uniswap, Cetus, PancakeSwap, Hyperliquid, and Soroswap across connected networks. Balanced's money market extends this cross-chain design: collateral posted on one chain can back a loan issued on a different chain, and bnUSD moves natively at 1:1 across all 13 networks. Solana joined the protocol in September 2024, enabling Solana-native wallets to access the full feature set — swaps, borrowing, and earning — connected to 12 other chains.

Spectrum Nodes supports more than 225 blockchain networks organized across mainnets, testnets, and devnets, spanning major Layer 1s, Ethereum Layer 2 networks, Cosmos ecosystem chains, and a long tail of niche and emerging networks that most providers do not cover. The company describes this breadth as deliberate, positioning itself for multichain development teams who would otherwise need to configure and maintain separate node infrastructure for each chain in their stack. Any public blockchain can be added on request. All supported networks are accessible through a common RPC and WebSocket interface that eliminates per-chain configuration differences and centralizes monitoring under a single dashboard. More than 20 chains also receive access to enriched APIs covering tokens, NFTs, portfolio aggregation, pricing, and DeFi positions on top of the standard JSON-RPC access available across the full catalog. Documented clients include Chainlink, Polkadot, and Oasis Network, reflecting an orientation toward teams operating across multiple ecosystems rather than those concentrated on a single chain.

Printr uses Axelar and LayerZero as its cross-chain communication layer, enabling single-transaction swaps and one-click bridging across more than twelve blockchains. The platform abstracts gas and routing at the application level so users can transact across networks without managing multiple wallets. Token deployments reach all supported chains simultaneously, eliminating the fragmented liquidity that separate per-chain launches create. Supported networks include Solana, Base, BNB Chain, Ethereum, Mantle, Monad, Avalanche, Arbitrum, and others. For Solana-based projects, this allows tokens to reach EVM ecosystems without splitting community attention or forking liquidity. Governance token holders vote on chain expansion, meaning supported chains can grow through community proposals. The Printr team is largely composed of Axelar alumni, reflecting the platform's deep integration with that protocol.

NEAR Mobile's cross-chain capability is powered by NEAR Intents, a chain abstraction protocol native to NEAR Protocol that routes swap orders through a network of solvers fulfilling trades with native tokens on their respective chains. Users can swap assets across Bitcoin, Ethereum, Solana, and XRP directly from the mobile app without wrapping assets through a traditional bridge or routing through a centralized exchange account. As of early 2025, supported assets expanded to include XAUT, VVV, DASH, USAD, and USDCx, and Rhea Finance was added as an additional trading interface alongside the native NEAR Intents integration. The Solana connection within this system is direct: NEAR Protocol's native token is available as a Solana-side asset through NEAR Intents, allowing value to move between the NEAR and Solana ecosystems using native token settlement rather than wrapped intermediaries. For participants active across both networks, NEAR Mobile represents one of the available interfaces for accessing cross-chain liquidity from a mobile device without a custodial intermediary. The DEX integration with Ref Finance, NEAR Protocol's primary on-chain exchange, further extends the cross-chain routing surface available to wallet users.

RHEA Finance is built around NEAR Protocol's Chain Signature technology, which enables smart contracts on NEAR to cryptographically sign transactions on external blockchains — including Bitcoin, EVM-compatible networks, Zcash, and Solana — without locking assets in bridge contracts or issuing synthetic tokens on destination chains. This approach eliminates the counterparty risk associated with centralized custodians and removes the complexity of managing wallets across multiple networks. RHEA also integrates with NEAR Intent, a decentralized intent settlement layer, to route cross-chain operations more efficiently. The practical result is that users on other chains can access RHEA's NEAR-side liquidity without leaving their native environment. In November 2025, RHEA launched cross-chain lending through Solflare — a Solana-native wallet — allowing Solana users to interact with NEAR-side lending markets using USDC, USDT, and ZEC as initial assets. A dedicated Satoshi Ramp provides Bitcoin users a direct entry point to access yield opportunities without first converting BTC to a wrapped token on another chain.

Calyx is built on two core cross-chain infrastructure layers: NEAR Intents and OmniBridge. NEAR Intents is an interoperability layer on NEAR Protocol that resolves cross-chain routing and swaps behind the scenes, eliminating manual bridging for token sale participants. As of late 2025, NEAR Intents had processed over $4 billion in total swap volume. OmniBridge makes launched tokens natively portable across all 19+ supported networks without requiring projects to redeploy contracts on each chain. The cross-chain design extends through the full token lifecycle: participants on Solana, Ethereum, Bitcoin, BNB Chain, and other networks can join the same sale with assets they already hold and withdraw vested tokens to any supported chain. A third component, the Agentic Market Maker, handles automatic post-sale liquidity rebalancing across chains. The aggregate cross-chain liquidity accessible through NEAR Intents is cited at over $100 billion.

DapDap's StableFlow is a cross-chain bridge built on the NEAR Intents protocol connecting Solana to Ethereum, Arbitrum, Polygon, BNB Chain, Optimism, Avalanche, NEAR, and Tron. Instead of routing transfers through AMM pools, StableFlow uses a decentralized solver network where professional market makers compete to fill a transfer intent, eliminating the liquidity fragmentation that accumulates slippage on conventional bridges. Settlement is atomic via a Verifier Smart Contract on NEAR Protocol: transfers either complete in full across source and destination chains or revert automatically with funds returned, with no partial states. The d'Avinci gateway also includes Super Bridge, a cross-chain asset transfer tool for EVM-compatible networks optimizing transactions for speed and cost. No destination-chain gas tokens are required, as StableFlow uses a chain-abstracted account model.

dep.now is a cross-chain deposit and swap aggregator that routes assets between networks without requiring users to interact with individual bridges separately. Its Swap mode lets users select input and output tokens across any supported chain and execute the transfer in a single interface, with failed transactions automatically refunding to the source wallet to remove a common failure mode in multi-hop cross-chain flows. The tool's primary application is onboarding capital into perpetual DEX trading accounts, but its cross-chain routing layer handles general asset movement as well. A user holding ETH on Ethereum or SOL on Solana can route directly into exchanges like Hyperliquid on Arbitrum without touching a separate bridge interface. This focused approach distinguishes dep.now from general-purpose bridges and positions it as a utility layer for active traders managing assets across multiple networks.

Ping is built on NEAR Intents, a cross-chain infrastructure layer that handles routing and settlement logic for multi-chain payments. When a transaction is initiated, the intent is broadcast to the network, which resolves the optimal path including any required token swaps and bridge hops to deliver funds in the recipient's preferred asset on their preferred chain, without requiring end users to manage the underlying cross-chain mechanics. The architecture is chain-agnostic at the settlement layer, with NEAR Intents coordinating asset movement across NEAR, Ethereum, Bitcoin, and other connected networks. Developers writing to the Ping API do not need to implement chain-specific integration logic, as the unified interface handles payment execution regardless of which networks are involved. The onramp SDK demonstrates this cross-chain capability in a consumer-facing context, converting fiat deposits through Coinbase Onramp into USDC on Base, then routing them through NEAR Intents to arrive in any supported asset and wallet on a target network in roughly 30 seconds. In-platform swaps powered by the same intent-based infrastructure let users move between assets and chains as part of a payment workflow without visiting a separate bridge or exchange. Ping operates a public request form for teams that need support for additional chains or assets, as well as an onboarding process for additional onramp providers. This network-growth model expands cross-chain coverage through ecosystem integrations rather than requiring Ping to own proprietary bridge infrastructure for every supported network.

Omni supports cross-chain asset transfers and token swaps across more than 25 networks, including Bitcoin, Ethereum, Solana, Base, Arbitrum, Optimism, Polygon, BNB Chain, Avalanche, TON, TRON, and NEAR. Users can move assets between ecosystems and swap tokens across chains without leaving the app or maintaining separate wallets for each network. The multi-chain architecture is central to the wallet value proposition, setting it apart from ecosystem-specific wallets that fragment holdings across multiple applications. Solana holders can manage native SOL staking alongside EVM-based assets in a single unified interface, with cross-chain bridging available directly within the swap features built into the mobile app. This unified view of assets across chains addresses the fragmented experience most multi-chain users face today.

Swing is a cross-chain liquidity and bridge aggregation platform that routes transactions across blockchains through the optimal path rather than requiring users to navigate individual bridges. Its routing engine aggregates quotes from multiple bridge providers and DEX aggregators simultaneously, converts assets into bridge-compatible stable tokens on the source chain, and commits only to the route that delivers the best net price across both source and destination chain liquidity pools. Solana is supported through a deBridge partnership, enabling transfers between Solana and major EVM chains including Ethereum, Arbitrum, Avalanche, Optimism, BNB Chain, Polygon, and Linea. The platform's 2025 roadmap adds Solana intents developed with Velora Delta for gasless cross-chain execution, while a developer SDK allows any dApp or wallet to embed cross-chain transfer functionality in minimal code under a revenue-sharing model with integration partners.

ZOLANEAR's ShadeLink platform functions as a cross-chain automation layer connecting Zcash, NEAR Protocol, and Solana through a single programmable instruction. It uses NEAR Intents OmniBridge as the primary bridging infrastructure, enabling users to move ZEC from Zcash to Solana while simultaneously scheduling follow-up DeFi actions. The system normalizes address formats across three chains — Ed25519 for Solana, NEP-413 for NEAR, and standard Ethereum formats — so assets held at any of these addresses can trigger automated cross-chain workflows without manual handoffs between networks. The atomic bridge-and-action design eliminates the multi-step manual process of first bridging assets and then separately executing DeFi transactions on the destination chain. When ShadeLink detects that NEAR-intent-bridged funds have arrived on Solana, it immediately chains follow-up transactions such as Jupiter DEX swaps or lending protocol deposits, all without the user remaining online or approving each step. Because the underlying NEAR Intents infrastructure supports an expanding set of asset pairs, ShadeLink's cross-chain automation can in principle extend beyond ZEC to other tokens that NEAR Intents routes across chains.

depouch is a cross-chain swap interface built above two established non-custodial liquidity protocols — THORChain and Maya Protocol — enabling native asset transfers across 18 blockchains without bridging, wrapping, or custodial intermediaries. Settlement delivers the actual coin to the destination address: real BTC, real SOL, real ADA rather than synthetic representations. This native-settlement model eliminates the bridge and wrapped-token risks responsible for large-scale losses in other cross-chain systems. Solana integration arrived through THORChain's native SOL support launching in February 2026, giving SOL holders a permissionless path to swap into assets on other chains and giving users of other chains a KYC-free route to acquire SOL. NEAR Intents serves as a third routing option and fallback during protocol-level outages. Sanctioned-address screening is built into the swap flow, and the team publicly flags attacker addresses during protocol-level security incidents. Supported chains include Bitcoin, Ethereum, Solana, Cardano, Tron, Dogecoin, Litecoin, Cosmos, Avalanche, and others across 18 networks.

Swaponix connects over 1,500 digital assets across separate blockchain networks, serving as a practical bridge for users who need to move value between chains without using a centralized exchange. Its smart routing system sources liquidity from multiple exchange providers to optimize rates across different networks, handling the cross-chain leg automatically. The platform supports conversions between major networks including Solana, Bitcoin, Ethereum, Litecoin, Monero, and Zcash, among hundreds of others. The service is designed for users who want cross-chain transfers without the friction of identity verification, wallet connections, or custody handoffs. Solana holders can convert SOL to assets on any supported network in a single flow: submit a destination address, send funds to a generated deposit address, and receive converted assets — without the platform holding the user's funds in any intermediary account between steps.
