The 1inch Network offers efficient protocols for liquidity discovery and token trading - open-source and onchain..

Secure

Gas-efficient

Flexible

1inch protocols are secure by design and built on the most-audited smart contracts in DeFi.

1inch protocols are optimized to manage network fees and help traders discover the most efficient swap routes.

1inch protocols were created as building blocks for future products and possibilities - as shown by the modular construction of Fusion and Fusion+.

Integrate 1inch DeFi protocols

1inch Aggregation Protocol

The foundational 1inch smart contract, designed to execute token swaps with maximum liquidity access and minimum gas costs.

1inch Limit Order Protocol

1inch Network's v4 Limit Order protocol combines traditional limit orders with the capacity to assemble gas-efficient RFQs or more advanced order structures. This is the basis of 1inch's intent-based swap protocols.

1inch Fusion Protocol

An intent-based swap protocol that deploys a Dutch auction model to incentivize solvers and maximize returns, removes gas fees, and prevents front-running and MEV attacks.

1inch Fusion+ Protocol

Built on the Fusion Protocol, 1inch's cross-chain swap protocol adds trustless atomic swaps between blockchain networks.

1inch Spot Price Aggregator

This set of smart contracts reports onchain spot prices in real time across DEXes & AMMs and powers 1inch's crypto price API. Protected against manipulation by screening out low-liquidity pools.
