Multi-chain decentralized exchange (DEX) aggregator 1inch has officially launched on the Solana blockchain
bringing its Fusion protocol, MEV-protected swaps, and six developer APIs to one of crypto’s fastest-growing ecosystems.
The integration marks a strategic move by Solana to capture the growing DeFi activity, which has seen it surpass other blockchains in DEX trading volume, transaction counts, and active addresses by the first quarter of 2025, according to data from Dune Analytics and DefiLlama.
As part of the rollout, 1inch is bringing on-chain swaps for over 1 million Solana-based tokens powered by its open-source smart contracts and intent-based commerce architecture.
The Fusion protocol allows users to set trading parameters, while professional market makers or resolvers compete to execute trades using a Dutch auction model.
This approach, where prices start high and gradually decline until a bid is accepted, aims to optimize pricing, reduce slippage and maximize liquidity.
“Our integration with Solana brings us closer to unifying different chains,” 1inch co-founder Sergej Kunz said in a statement.
Beyond this launch, 1inch plans to offer cross-chain swaps between Solana and 10 other supported blockchains in the coming months. This effort is designed to bridge liquidity between networks and increase the accessibility of DeFi protocols.
Founded in May 2019, 1inch has steadily expanded across the crypto landscape, previously launching on Ethereum’s Optimism scaling solution in 2021 and Coinbase’s Base chain in August 2023.
Among DEX aggregators, it currently ranks second after Jupiter, a native Solana protocol.
The expansion comes at a time when Solana is gaining renewed dominance in the DeFi space, with major integrations and partnerships signaling broader institutional interest in the network.
