Decentralized exchange aggregator 1inch has officially launched on Solana, advancing its goal of building a unified multichain DeFi ecosystem. The integration allows users to swap over one million Solana-based tokens via the 1inch decentralized application (DApp), with optimized rates, MEV protection, and open-source smart contracts.
The launch also introduces 1inch’s Fusion protocol to Solana. Fusion lets users define swap preferences, which are then executed through a Dutch auction involving professional market makers—called “resolvers”—to improve execution while reducing slippage and costs.
By combining 1inch’s trade-optimization architecture with Solana’s fast block times and low fees, the new integration offers a significantly smoother trading experience compared to many Ethereum-based or layer-2 platforms.
The expansion arrives as Solana continues to outperform other networks across multiple DeFi benchmarks. Over the last three months, Solana has recorded 33% higher DEX volumes, 400% more transactions, and 180% more active wallet addresses than its competitors.
Cross-Chain Swaps Between Solana and 10+ Chains Incoming
Alongside the Solana launch, 1inch confirmed it is developing cross-chain swap capabilities linking Solana to over 10 other blockchains. This upgrade will enable users to move assets between networks seamlessly without leaving the 1inch interface.
Though a launch date has yet to be announced, a 1inch representative said development is underway, and the rollout will begin with the blockchains already supported in its current cross-chain infrastructure.
The feature is seen as a major strategic step in 1inch’s long-term multichain vision. It comes as Solana gains momentum across DeFi, boasting $539 billion in DEX volumes over the past quarter, according to Dune Analytics.
1inch Empowers Builders With APIs and Developer Tools
To support innovation on Solana, 1inch has released six core APIs via its Developer Portal. These tools aim to empower developers to build DApps and services on top of the expanding 1inch-Solana infrastructure.
This initiative reinforces 1inch’s commitment to solving blockchain fragmentation. In September 2024, 1inch published a white paper detailing an intent-based, cross-chain protocol to tackle liquidity fragmentation.
Shortly after, the platform launched Fusion+, a self-custodial product enabling users to execute cross-chain swaps without surrendering wallet control. Fusion+ offers greater asset flexibility, security, and interoperability—key priorities in today’s DeFi landscape.
