The decentralized aggregation trading protocol 1inch announced its formal integration into the Solana ecosystem, deploying its Fusion protocol, on-chain swapping functionality, and six developer APIs to the Solana network.
According to official sources, this integration allows tokens within the Solana ecosystem to conduct transactions with MEV protection.

The overall trading architecture adopts 1inch's open-source smart contracts and an intent-based design, allowing users to simply define what actions they want to execute, with the backend resolver responsible for optimizing execution.
Specifically, users can customize trading parameters, while professional market makers (resolvers) will bid to execute trades on the backend through a Dutch auction model—where the exchange rate gradually decreases from a higher price until accepted by a resolver. This mechanism is designed to reduce slippage risk and achieve the best swap price through competitive bidding.
According to data from Dune Analytics and DefiLlama, Solana led all public chains in several DeFi metrics in the first quarter of 2025, including DEX trading volume, number of transactions, and number of active addresses.
Next, 1inch plans to launch cross-chain swapping functionality between Solana and the remaining 10 supported chains, further linking Solana's liquidity with the broader DeFi ecosystem.
