1inch is a unified DeFi ecosystem, built around the DEX aggregator with the best swap rates.
Swap, hold & track digital assets - and ship scalable, secure applications with the complete Web3 stack.
1inch protocols access hundreds of liquidity sources across 12+ chains, including Solana, for secure trading at the best rates. Builders can unlock them all with 1inch Developer Portal: 17 APIs that bring you the technologies you need to scale.
The 1inch Swap API gives you optimized routes with the new Pathfinder algorithm; Fusion and Fusion+ are the building blocks of intent-based and cross-chain swaps, with MEV protection and zero gas fees as standard. The rest offer everything from spot price and node access to limit orders and dynamic gas pricing.
With complete usage statistics and API management, custom plan configuration, and a one-click Swagger UI - 1inch APIs and the Developer Portal give you the tools and adaptability you need to build your project.
