The best decentralized exchanges, reviewed

A decentralized exchange is a peer-to-peer marketplace where crypto trades execute directly on the blockchain via smart contracts. Unlike centralized exchanges such as Coinbase or Binance, a DEX never takes custody of your funds — you trade straight from your own wallet, and settlement is enforced by code rather than a company.

A decentralized exchange protocol does not open an account for you. You connect a self-custody wallet and pay network fees. That is separate from the exchange, wallet, and event-contract services offered with our regulated partners. Those services require identity verification and sanctions screening under an AML/KYC program before you can use them. See the Policy for which firm provides each service.

Automated market makers (AMMs) like Uniswap price trades algorithmically against liquidity pools funded by other users. Order-book DEXs like Hyperliquid and dYdX match individual buy and sell orders, like a traditional exchange. AMMs are simpler and always liquid; order books offer tighter pricing and advanced order types for active traders.

Most spot AMMs charge 0.01%–0.3% per swap, paid to liquidity providers. On top of that you pay the blockchain's network (gas) fee — a few cents on L2s, Solana or BNB Chain, and more on Ethereum mainnet. Perpetuals DEXs typically charge maker/taker fees similar to centralized venues.

DEXs remove custodial risk — the exchange can't run away with your funds — but they introduce smart-contract risk. Stick to battle-tested protocols from this directory, always verify you're on the official URL, start with small amounts, and consider a hardware wallet for meaningful size.
