The initial protocol of the 1inch Network is a decentralized exchange (DEX) aggregator that sources liquidity from various exchanges and is capable of splitting a single trade transaction across multiple DEXes. Smart contract technology empowers this aggregator enabling users to optimize and customize their trades. The 1inch Network was launched at the ETHGlobal New York hackathon in May 2019 with the release of its Aggregation Protocol v1. Since then, the 1inch Network has developed additional DeFi tools such as the Liquidity Protocol, the Limit Order Protocol, P2P transactions, the Fusion mode, and the 1inch Wallet app.
