What Is Uniswap?
Uniswap is a decentralized exchange protocol that allows users to trade ERC-20 tokens directly from their wallets. Unlike centralized exchanges such as Binance or Coinbase, Uniswap does not hold user funds — you remain in control of your private keys.
Uniswap uses an automated market maker (AMM) model. Instead of matching buyers and sellers, it uses liquidity pools where users deposit tokens. Prices are determined by a mathematical formula, ensuring continuous liquidity.
