1inch, a prominent decentralized exchange (DEX) aggregator, has made its mark on Solana, bringing its Fusion protocol, MEV-protected swaps, and six developer APIs to one of the crypto world’s most dynamic ecosystems. This strategic move aligns with Solana’s rapid growth in DeFi activity, which surpassed other blockchains in trading volume, transaction counts, and active addresses by Q1 2025, according to data from Dune Analytics and DefiLlama. 1inch is now powering on-chain swaps for over a million Solana tokens using its open-source smart contracts and intent-based commerce architecture.
The Fusion protocol empowers users to set trading parameters, while professional market makers or resolvers compete to execute trades through a Dutch auction model, aiming to optimize pricing, reduce slippage, and maximize liquidity. This approach starts bids high and gradually lowers them until someone accepts.
