What Is DEX (Decentralized Exchange)?
Definition
A DEX is a peer-to-peer exchange that enables cryptocurrency trading directly from your wallet without intermediaries, using smart contracts to match trades.
A decentralized exchange (DEX) is a platform for trading cryptocurrencies without a central authority. Unlike centralized exchanges (Coinbase, Binance), DEXes use smart contracts to facilitate trades directly between users' wallets.
- AMM (Automated Market Maker): Uses liquidity pools instead of order books. Traders swap against a pool of tokens. Examples: Raydium, Uniswap, PancakeSwap.
- Order Book: Matches buy and sell orders like traditional exchanges. Examples: OpenBook (Solana), dYdX.
- Listing is permissionless — you don't need exchange approval to list your token
- You create the initial market by providing liquidity to a pool
- Trading starts immediately after pool creation
- No KYC — anyone with a wallet can trade
To list your token on a DEX, you need to create a liquidity pool pairing your token with a base asset (SOL, ETH). CoinDevTools handles the pool creation for Raydium (Solana) and Uniswap v2 (Ethereum/Base).
