1inch Expands to Solana, Sets Sights on Crosschain DeFi Growth

Decentralized trading aggregator 1inch has expanded onto Solana, offering faster and cheaper swaps across more than a million tokens.

With this move, users can now access Solana’s rapid transaction speeds and low fees — reportedly under one cent per swap — through 1inch’s decentralized app.

The integration brings 1inch’s Fusion protocol to Solana for the first time, allowing users to customize their trades, with professional market makers competing to fulfill them through Dutch auction mechanics. This setup, paired with Solana’s efficiency, is expected to deliver smoother DeFi trading than most existing networks.

In addition to the Solana expansion, 1inch plans to enable crosschain swaps, connecting Solana to ten or more other blockchains already supported by 1inch. Although a launch date hasn’t been confirmed, development is said to be progressing quickly.

Solana’s surge in DeFi activity supports the timing of the move: it recently outpaced Ethereum and major layer-2s in DEX volume, transaction count, and user activity, according to Dune Analytics.

To further encourage innovation, 1inch is opening access to six APIs through its Developer Portal, offering builders tools to create new applications using the 1inch-Solana infrastructure.

This strategic push follows 1inch’s 2024 unveiling of its crosschain interoperability protocol and Fusion+ feature, both designed to connect blockchain ecosystems while preserving user custody of assets.
