Decentralized exchanges (DEXes) are blockchain-based platforms that enable peer-to-peer cryptocurrency trading without intermediaries. Unlike centralized exchanges like Coinbase or Binance, DEXes operate via smart contracts, offering greater privacy, security, and control over your assets. In 2022 alone, DEXes facilitated over $850 billion in trades across 5 million+ users.
How Does a Decentralized Exchange Work?
DEXes like Uniswap or Matcha leverage open-source smart contracts to execute trades directly on-chain. Here’s how they function:
- Wallet Integration: Users connect self-custody wallets (e.g., MetaMask, Coinbase Wallet) to trade instantly—no sign-ups or KYC required.
- Trustless Settlement: Transactions settle automatically on the blockchain, eliminating third-party involvement.
- Cross-Chain Availability: While Ethereum hosts the most popular DEXes, they exist on multiple blockchains (e.g., Solana, BSC).
