Available across the 1inch dApp, wallet, and Fusion+ API, users can now move assets directly between Solana and all major EVM networks in a fully decentralized, secure, and seamless way with full MEV protection.
Until now, cross-chain interaction between Solana and EVM networks has typically required bridges or third-party messaging protocols such as Wormhole, Axelar, LayerZero, or Chainlink CCIP. While widely used, these systems have proven to be vulnerable, with bridge hacks one of the most damaging security risks in DeFi.
“There is no bridge risk, because the funds remain in their respective chain-specific escrows, not in a shared pool, and no one can move them without the user’s secret. After a security check, the user shares this secret with the resolver to authorize withdrawal. If the secret is never shared, both escrows are canceled and funds are returned to their original owners.”
The technical foundation for this feature builds on 1inch Fusion+, the firm’s Dutch Auction settlement model. But as Kunz explained, getting it to work with Solana required rethinking the architecture:
“The biggest technical challenge was adapting our Fusion+ architecture, originally designed for EVM-to-EVM swaps, to work natively with Solana. Instead of relying on third-party messaging protocols or bridges, we combined 1inch’s Dutch Auction model with cryptographically linked, chain-specific escrow contracts and programs. This allows resolvers to settle cross-chain orders atomically and trustlessly, bypassing the traditional two-step bridge model and eliminating shared-pool risks.”
The process works as follows: A user signs a cross-chain swap order on the source chain. A resolver locks matching liquidity on the destination chain while the user’s funds are held in escrow on the source chain.
Only when a cryptographic secret is revealed can both escrows unlock atomically, ensuring no party can run off with funds. As Kunz explained, if the process fails, both escrows are cancelled and funds are returned.
Beyond eliminating bridge risk, Fusion+ cross-chain swaps help reduce fragmentation by allowing assets to stay in their native ecosystem while still being instantly swappable across chains. Kunz pointed out:
“Instead of splitting liquidity into bridge pools, resolvers use their own inventory to fulfill orders on the destination chain. This means Solana and EVM liquidity can serve each other without requiring re-wrapped tokens, creating more efficient markets and deeper effective liquidity across ecosystems.”
For Solana, this addresses one of its biggest historical hurdles: isolation from DeFi innovation and capital flows in EVM chains. Solana-native tokens can now be traded directly against Ethereum, Polygon, Arbitrum, and others, without intermediaries, bringing new users, capital, and dApps to Solana while making the network a hub for traders, builders, and liquidity providers.
While today’s release covers Solana<>EVM swaps, the team has further ambitions. Kunz told CryptoSlate:
“We’re open to integrating more non-EVM networks in the future. At our recent hackathon, teams demoed implementations for Bitcoin, Sui, Aptos, and others. That showed us the strong demand for a broader multichain future where every asset can talk to every other without bridge risk.”
