Decentralized exchanges empower users to trade cryptocurrencies directly from their wallets without relying on centralized intermediaries. By eliminating third-party custody risks, DEXs ensure users maintain full control over their digital assets. Leveraging smart contracts, these platforms automate transactions based on predefined conditions, fostering transparency and tamper-proof trading environments.

What Is a Decentralized Exchange?
Decentralized exchanges (DEXs) differ fundamentally from centralized exchanges (CEXs). CEXs operate like banks—users deposit crypto, and the platform manages custody. In contrast, DEXs facilitate peer-to-peer trading via smart contracts, ensuring:
- Self-custody: Users retain private keys.
- No intermediaries: Trades execute trustlessly.
- Transparency: All transactions are on-chain.
💡 Key Difference: CEXs require KYC; DEXs prioritize anonymity.
