1inch
The original protocol of the 1inch Network is a decentralized exchange (DEX) aggregator that gathers liquidity from different exchanges and can divide a single trade transaction among several DEXes. This aggregator is empowered by smart contract technology, allowing users to tailor and enhance their trading experience. The 1inch Network debuted at the ETHGlobal New York hackathon in May 2019 with the introduction of Aggregation Protocol v1. Since that time, the 1inch Network has created extra DeFi tools like the Liquidity Protocol, the Limit Order Protocol, P2P transactions, the Fusion mode, and the 1inch Wallet application.
