1inch launches trustless Solana cross-chain swaps, bypassing bridges entirely

Leading DEX aggregator 1inch has introduced a caller DeFi feature: trustless cross-chain swaps betwixt Solana and implicit 12 EVM networks, without relying connected bridges oregon third-party messaging protocols.

Available crossed the 1inch dApp, wallet, and Fusion+ API, users tin present determination assets straight betwixt Solana and each large EVM networks successful a afloat decentralized, secure, and seamless mode with afloat MEV protection.

Bridgeless Solana cross-chain swaps

Until now, cross-chain enactment betwixt Solana and EVM networks has typically required bridges oregon third-party messaging protocols specified arsenic Wormhole, Axelar, LayerZero, oregon Chainlink CCIP. While wide used, these systems person proven to beryllium vulnerable, with span hacks 1 of the astir damaging information risks successful DeFi.

In February 2022, the Wormhole bridge, which connects Solana and Ethereum, was hacked, resulting successful a nonaccomplishment of implicit $320 million. Attackers exploited a vulnerability successful Wormhole’s signature verification process, enabling them to mint $120,000 worthy of wrapped ETH connected Solana without the required collateral connected Ethereum. This drained funds from the protocol and exposed the risks inherent successful accepted bridge-based cross-chain solutions.

1inch’s bridgeless Solana cross-chain swaps rewrite this exemplary entirely. When the resolver accepts a price, an escrow is created connected the root chain, securely locking the user’s funds. The resolver past creates a matching escrow connected the destination chain, locking their ain funds. 1inch co-founder Sergej Kunz told CryptoSlate:

“There is nary span risk, due to the fact that the funds stay successful their respective chain-specific escrows, not successful a shared pool, and nary 1 tin determination them without the user’s secret. After a information check, the idiosyncratic shares this concealed with the resolver to authorize withdrawal. If the concealed is ne'er shared, some escrows are canceled and funds are returned to their archetypal owners.”

Under the hood: Fusion+ cross-chain

The method instauration for this diagnostic builds connected 1inch Fusion+, the firm’s Dutch Auction colony model. But arsenic Kunz explained, getting it to enactment with Solana required rethinking the architecture:

“The biggest method situation was adapting our Fusion+ architecture, primitively designed for EVM-to-EVM swaps, to enactment natively with Solana. Instead of relying connected third-party messaging protocols oregon bridges, we combined 1inch’s Dutch Auction exemplary with cryptographically linked, chain-specific escrow contracts and programs. This allows resolvers to settee cross-chain orders atomically and trustlessly, bypassing the accepted two-step span exemplary and eliminating shared-pool risks.”

The process works arsenic follows: A idiosyncratic signs a cross-chain swap bid connected the root chain. A resolver locks matching liquidity connected the destination concatenation portion the user’s funds are held successful escrow connected the root chain.

Only erstwhile a cryptographic concealed is revealed tin some escrows unlock atomically, ensuring nary enactment tin tally disconnected with funds. As Kunz explained, if the process fails, some escrows are cancelled and funds are returned.

Beyond eliminating span risk, Fusion+ cross-chain swaps assistance trim fragmentation by allowing assets to enactment successful their autochthonal ecosystem portion inactive being instantly swappable crossed chains. Kunz pointed out:

“Instead of splitting liquidity into span pools, resolvers usage their ain inventory to fulfill orders connected the destination chain. This means Solana and EVM liquidity tin service each different without requiring re-wrapped tokens, creating much businesslike markets and deeper effectual liquidity crossed ecosystems.”

For Solana, this addresses 1 of its biggest humanities hurdles: isolation from DeFi innovation and superior flows successful EVM chains. Solana-native tokens tin present beryllium traded straight against Ethereum, Polygon, Arbitrum, and others, without intermediaries, bringing caller users, capital, and dApps to Solana portion making the web a hub for traders, builders, and liquidity providers.

What’s adjacent for 1inch

While today’s merchandise covers Solana<>EVM swaps, the squad has further ambitions. Kunz told CryptoSlate:

“We’re unfastened to integrating much non-EVM networks successful the future. At our caller hackathon, teams demoed implementations for Bitcoin, Sui, Aptos, and others. That showed america the beardown request for a broader multichain aboriginal wherever each plus tin speech to each different without span risk.”

The station 1inch launches trustless Solana cross-chain swaps, bypassing bridges entirely appeared archetypal connected CryptoSlate.
