The multi-chain DEX aggregator 1inch has officially launched on Solana, bringing the Fusion protocol, onchain trading, and six APIs for developers, according to the project's announcement.
This integration allows MEV-protected transactions for over 1 million tokens on Solana, using 1inch's open-source smart contracts and intent-based trading architecture. The intent here is the end goal of users in a decentralized application or blockchain ecosystem.
With the launch on Solana, users can define transaction parameters, while professional market makers (also called resolvers) compete to execute trading orders through a Dutch auction model – where the exchange rate starts high and decreases until a resolver accepts the transaction. This system aims to reduce slippage and optimize transaction prices with extensive liquidation.
DeFi activity on Solana has grown significantly in the first quarter of 2025, leading in DEX trading volume, number of transactions, and active addresses, according to data from dune analytics and defillama. In the coming months, 1inch plans to implement cross-chain trading between Solana and 10 other supported networks, aiming to connect Solana's liquidation with a broader DeFi market.
"The integration with Solana helps us move closer to connecting different chains," said Sergej Kunz, co-founder of 1inch. This DeFi project, launched in May 2019 and currently second among DEX aggregators, only behind Jupiter, has also launched on Base in August 2023 and on Ethereum's Optimism scaling solution in 2021.
