What are decentralized exchanges (DEX)?
👉 DEX (Decentralized Exchange) is an exchange where trading occurs directly from your wallet, without intermediaries.
🔹 How it works:
You connect your wallet (for example, MetaMask).
You choose a pair (for example, ETH → USDC).
Your transaction is executed by a smart contract.
No one holds your money. The keys are only with you.
📌 Popular DEX:
Uniswap (Ethereum)
PancakeSwap (BNB Chain)
Curve, Sushi, dYdX
