Decentralized exchange aggregator 1inch has officially launched on Solana, unlocking its Fusion protocol, on-chain swapping, and six developer-focused APIs on one of the fastest networks in the blockchain space.
The move brings MEV-resistant swaps to more than 1 million tokens on Solana, powered by 1inch’s open-source smart contracts and intent-based trade architecture. In this system, users define their desired trade outcomes, while professional resolvers — advanced market makers — compete in a Dutch auction format to fulfill those orders, starting with a higher rate that declines until it is accepted.
This mechanism is designed to minimize slippage, optimize execution prices, and leverage deep liquidity available across the Solana ecosystem.
Solana Leads DeFi in 2025 — and 1inch Wants a Bigger Piece
Solana dominated DeFi metrics in Q1 2025, leading in DEX trading volume, transaction throughput, and active user addresses, according to data from Dune Analytics and DeFiLlama. Riding this momentum, 1inch is already planning cross-chain swap functionality between Solana and its 10 other integrated blockchains — a strategic move to connect Solana’s liquidity with the wider decentralized finance world.
“Our goal is to break down silos across blockchain ecosystems, and Solana brings us one step closer,” said Sergej Kunz, 1inch co-founder.
1inch Continues Its Multi-Chain Strategy
Since its inception in May 2019, 1inch has grown to become the second-largest DEX aggregator, trailing only Jupiter. The protocol has previously expanded to Ethereum’s Optimism layer and Coinbase-backed Base, underscoring its commitment to multi-chain accessibility and developer-friendly infrastructure.
