Traditional exchanges (Coinbase, Binance) act as intermediaries: they take custody of your funds, match buyers and sellers, and require identity verification. DEXs eliminate all of this — you trade directly from your own wallet using smart contracts, retaining full custody throughout.
How Automated Market Makers (AMMs) Work
How Automated Market Makers (AMMs) Work
Traditional exchanges use order books — matching buy and sell orders from different users. AMMs replace order books with liquidity pools. Two tokens are deposited in equal value, and a simple formula (x * y = k) automatically calculates prices based on the ratio of reserves.
When you swap ETH for USDC on Uniswap, your ETH goes into the pool and USDC comes out, changing the ratio and therefore the next marginal price. Liquidity providers who deposited earn a share of every swap fee (0.05%–1% per trade depending on pool tier).
