What Is a Decentralized Crypto Exchange (DEX)?
A DEX operates similarly to traditional exchanges but eliminates central authorities. Key differences:
- P2P Trading: Direct transactions without intermediaries.
- Smart Contracts: AMMs like Uniswap use liquidity pools (e.g., DOGE/USDT) to facilitate trades.
- Transparency: All transactions are recorded on public blockchains.
DEX vs. Centralized Exchanges (CEX)
- Security: DEXs reduce hacking risks (e.g., no FTX-style collapses).
- Privacy: No KYC or personal data required.
- Fees: Lower costs by cutting intermediaries.
