Solana News Today: 1inch Erases Chain Boundaries with Trustless Solana-EVM Swaps

1inch has introduced a groundbreaking solution that enables direct cross-chain swaps between Solana and over 12 Ethereum Virtual Machine (EVM) networks, eliminating the need for traditional bridges or messaging protocols [1]. This marks the first time users can transfer assets between Solana and EVM networks in a secure, MEV-protected manner, without relying on intermediaries that pose potential security risks. The integration leverages 1inch's native decentralized architecture and is now available via the 1inch decentralized application (dApp), 1inch Wallet, and 1inch Fusion+ API [4].

The new functionality enhances security by allowing users to retain control of their assets throughout the entire swap process. Unlike traditional cross-chain solutions that require centralized custody or the use of potentially vulnerable smart contracts, 1inch’s approach is fully trustless and self-custodial. The system uses chain-specific escrow contracts and a Dutch Auction model, where resolvers compete to fulfill cross-chain orders, ensuring optimal rates and execution [2]. This innovation also extends to Solana’s ecosystem, offering developers the ability to integrate cross-chain swaps into their own projects via the Fusion+ API and SDK [1].

One of the key advantages of the new feature is its efficiency. By removing the need for bridges, 1inch has streamlined the cross-chain process, reducing both transaction costs and the time required to complete swaps. Users benefit from near-zero gas fees, as resolvers cover the majority of the costs. In addition, the system is designed to protect against maximal extractable value (MEV) attacks, a growing concern in decentralized finance (DeFi), by ensuring atomic execution of swaps [3]. This makes it particularly attractive for large-value transactions, where security and speed are paramount [4].

According to 1inch co-founder Sergej Kunz, this development is a major step toward a unified DeFi experience, where chain boundaries become increasingly irrelevant to the end user. "By enabling secure, direct swaps between Solana and EVM, we’re erasing one of the biggest boundaries in the space," Kunz stated [2]. He emphasized that the goal is to make it possible for users to access the best rates and security regardless of where liquidity is located. The integration also allows Solana and EVM liquidity to interoperate more efficiently without the need for centralized custody or additional token layers [2].

Looking ahead, Kunz envisions a DeFi landscape in which underlying blockchains become largely invisible to users. He predicts that within two to three years, a multichain DeFi stack could emerge, where protocols are chain-agnostic, and liquidity flows seamlessly across ecosystems. "Moving assets between chains will become an anachronism," he said, highlighting the potential for a more integrated and user-friendly DeFi environment [2]. In the near term, 1inch is also planning to expand support to additional non-EVM chains, furthering its mission to unify the DeFi space under a single, interoperable framework [4].

The launch of these cross-chain swaps follows 1inch’s recent integration with the Solana network in April 2025, which allowed users to trade Solana-based tokens directly within the platform [2]. The latest update builds on this by addressing one of the most pressing challenges in the blockchain industry: the fragmentation of liquidity across isolated networks. By enabling direct swaps between Solana and EVM chains, 1inch is helping to bridge the gap between two of the most active DeFi ecosystems, opening new opportunities for liquidity providers, traders, and developers alike [1].
