What is DEX (Decentralized Exchange)?
Also known as: decentralized exchange
A peer-to-peer exchange where token swaps execute via smart contracts and liquidity pools instead of a central order book.
A decentralized exchange lets users trade directly from their wallets without depositing funds with a custodian. Most memecoin DEXs are automated market makers: prices come from liquidity-pool ratios rather than matched buy/sell orders. Raydium and Orca (Solana), Uniswap (Ethereum), and PancakeSwap (BNB Chain) are leading venues.
DEXs are where memecoins live after graduating from a launchpad. Aggregators and screeners (DexScreener, Birdeye) index DEX activity so traders can track price, volume, liquidity, and holder data in real time.
Because anyone can list a token on a DEX, due diligence falls entirely on the buyer — there is no listing review like on a centralized exchange.
