1inch Adds Solana Compatibility to Cross-Chain Swap Ecosystem

TL;DR

• Solana integration: 1inch now enables direct, trustless swaps between Solana and 12+ EVM networks inside the Fusion+ dApp experience, removing bridges and messaging while aggregating liquidity for competitive pricing and consistent fills across volatile conditions for traders.
• Security focus: Swaps remain self-custodial with built-in MEV protection that helps prevent front running and sandwich patterns, pairing Solana’s speed and low fees with Dutch auction mechanics.
• Ecosystem impact: 1inch ranks second by aggregator volume at $13.9B over 30 days, trailing Jupiter at $26B, and this integration closes a long-standing gap, giving builders API and SDK access.

1inch has integrated Solana into its cross-chain swap ecosystem, enabling direct swaps between Solana and 12+ EVM networks without bridges or messaging. Users move value self-custodially through Fusion+ intents, where resolvers compete to fill orders at the best rates. The release emphasizes user safety, MEV protection, and execution that abstracts chain boundaries. It advances 1inch’s mission to unite DeFi liquidity and opens Solana to deeper capital.

Swap Solana across 13+ chains, without bridges.

What 1inch launched

Users can now exchange assets on EVM chains for assets on Solana using the Fusion+ feature in the 1inch dApp. Liquidity is aggregated across DeFi venues, routed to deliver competitive pricing and reliable fills. By removing third-party bridges and messaging like LayerZero or Chainlink CCIP, the integration brings a familiar experience to a new corridor, aligned with self-custody expectations.

How it works

Fusion+ uses intent-based orders that specify outcomes rather than paths, allowing resolvers to compete via Dutch auction mechanics until a match clears. This approach compresses complexity for users and lifts execution quality in volatile markets. On Solana, short block times and low fees combine with aggregator logic to reduce slippage and improve final rates. Builders can use the Fusion+ API and SDK to wire cross-chain swaps into apps.

Security and performance

1inch positions the Solana corridor as safer than alternatives by keeping swaps self-custodial and removing external bridge dependencies. MEV protection is built into the flow, helping prevent front running and sandwich patterns that erode outcomes. The team highlights higher security, seamless execution, and better rates as the core bundle for users moving a meaningful size. The result is a trustless route that does not compromise speed.

Market context and what changes

1inch is the second largest DEX aggregator by volume, with $13.9B in 30-day activity, trailing Jupiter at $26B. The Solana integration closes a gap between ecosystems and gives traders one interface for cross-chain opportunities. For developers, direct EVM to Solana support lowers integration risk and speeds shipping. 1inch plans to add more non-EVM chains as it pushes toward unified DeFi access.
