What is 1inch? (1INCH) 1inch is a decentralized exchange aggregator that aims to provide traders with the best price and lowest fees on their transaction. Decentralized exchanges (DEXs) are part of the decentralized finance (DeFi) ecosystem that allow traders to exchange crypto assets without an intermediary executing the order, custodying funds or otherwise overseeing the transaction. DEXs allow traders to maintain custody over their funds in their wallets, without the need to share personal identifying information. At any given time across decentralized exchanges, prices and transaction fees can vary significantly. Rather than having to manually check and compare prices across exchanges, 1inch collects the real time pricing data from various DEXs to allow traders to identify the optimal price across the market and capture the trading opportunity within a single platform. Some of the popular exchanges that 1inch aggregates data from are Uniswap, SushiSwap, 0x, Kyber Network and Balancer.
