Catena, Tuesday, May 13, 2025-1inch, the second-largest decentralized exchange aggregator by trading volume, has launched support for Solana, the company announced Tuesday, deepening its reach in decentralized finance with plans to connect the network to 10 other blockchains via cross-chain swaps.
The integration enables users to access 1inch’s Fusion protocol, MEV-protected onchain swaps and six developer APIs across more than 1 million Solana tokens. The system uses intent-based smart contracts and Dutch auction-style pricing, where market makers — called resolvers — compete to fulfill orders by accepting declining rates, helping to minimize slippage and optimize execution prices.
“Solana’s performance metrics make it a strategic addition as we work to unite disparate chains into one cohesive DeFi environment,” said Sergej Kunz, co-founder of 1inch. He added that connecting liquidity between Solana and 10 existing supported chains will enhance overall efficiency in decentralized markets.
Solana led decentralized exchange activity during the first quarter of 2025, outperforming other blockchains in trading volume, transactions and active user count, according to data from Dune Analytics and DefiLlama. 1inch’s move aims to capitalize on that momentum while providing institutional-grade trading tools to the Solana ecosystem.
Launched in 2019, 1inch previously integrated with Base, a Coinbase-incubated network, in 2023 and Ethereum Layer 2 network Optimism in 2021. It trails only Jupiter as the leading DEX aggregator.
The company says it will roll out cross-chain swaps between Solana and other major DeFi ecosystems in the coming months, bolstering liquidity and lowering barriers to multi-chain interoperability.
