DEX
Bourse decentralisee permettant le trading crypto pair-a-pair sans intermediaire.
DEXs run entirely on smart contracts, allowing users to trade tokens directly from their wallets without depositing funds into a centralised platform. Uniswap, SushiSwap, and Curve are among the most prominent Ethereum DEXs, while Jupiter dominates Solana.
Most DEXs use an automated market maker (AMM) model rather than a traditional order book. Liquidity providers deposit token pairs into pools, and traders swap against these pools with prices determined algorithmically. Some newer DEXs, like dYdX, use on-chain order books.
DEX trading volume has grown from a tiny fraction of total crypto volume to a significant share, often exceeding 15-20% of CEX volume. DEX-to-CEX volume ratio is watched as an indicator of decentralisation progress and DeFi health.
DEXs represent the decentralisation ethos of crypto, offering censorship-resistant trading. Their growing volume share reflects maturing DeFi infrastructure.

FAQ
How is a DEX different from a CEX?
A DEX runs on smart contracts with no central operator. Users keep custody of their funds. A CEX holds user funds and operates an order book centrally.
Are DEXs safe?
DEXs eliminate custodial risk but introduce smart-contract risk. Bugs, exploits, and rug pulls in pool tokens are the primary dangers.
What is slippage on a DEX?
Slippage is the difference between expected and actual execution price, caused by trade size relative to pool liquidity. Larger trades on thinner pools see more slippage.
Do DEXs charge fees?
Yes. Swap fees (typically 0.05-1%) go to liquidity providers. Users also pay blockchain gas fees for each transaction.
