What Is a Decentralized Exchange (DEX)?
A DEX enables peer-to-peer crypto trading without intermediaries. Key features include:
- Liquidity Pools: Users contribute funds to pools, earning rewards in return.
- Global Access: No geographical restrictions; part of the DeFi (Decentralized Finance) ecosystem.
- Self-Custody: Users retain control of their assets via connected wallets (e.g., MetaMask).
Types of DEXs:
- Order Book-Based: Matches buyers/sellers via order books (e.g., dYdX).
- Automated Market Makers (AMMs): Uses algorithms (e.g., Uniswap’s
x*y=kformula) to facilitate trades via liquidity pools.

- Additional Services: Staking, loans, and educational resources.
How CEXs Work:
- Users deposit funds, managed by the exchange.
- Trades execute via centralized order books.
