What is Decentralized Exchange?

A cryptocurrency exchange that operates without a central authority, allowing peer-to-peer trading without KYC requirements or custodial risk.

Also known as: DEX

DEXs enable cryptocurrency trading without trusting a central company with your funds or identity.

How They Work

  • Smart contracts handle trade execution and settlement
  • Users trade directly from their wallets
  • No account registration, email, or identity verification
  • Funds never leave user custody (no "exchange wallet")

Privacy Benefits

  • No KYC/AML requirements on most DEXs
  • No account linking your identity to your trades
  • No centralized database of trading activity to be hacked or subpoenaed

Popular DEXs

  • Uniswap: Largest Ethereum DEX
  • dYdX: Derivatives trading
  • THORChain: Cross-chain swaps
  • Bisq: Bitcoin/fiat trading without intermediaries

Limitations

  • Trading on public blockchains (Ethereum) means trades are publicly visible
  • Privacy coins on DEXs provide the best privacy combination
  • Front-running (MEV) is a risk on transparent blockchains
  • Liquidity can be lower than centralized exchanges
