DEX vs CEX: which kind of crypto exchange should you use?
A decentralized exchange (DEX) like Snake DEX runs entirely on smart contracts — you trade peer-to-pool from your own wallet. A centralized exchange (CEX) such as Coinbase or Binance custodies your funds and matches orders on an internal off-chain order book. The difference matters most when something goes wrong.
The six differences that matter
Custody
Transparency
Counterparty risk
Listings
Execution model
Tradeoffs
Why self-custody is the headline
On a CEX you don't actually own the coins on screen — you own a balance entry the exchange promises to honor. Outages, insolvencies, and regulatory freezes have repeatedly stranded user funds. On Snake DEX every swap, pool deposit, and fee claim is signed by your wallet and settled by an audited router contract. There is no "withdrawal queue" because there is nothing to withdraw from.
When a CEX still makes sense
CEXs are usually the simplest path to convert fiat into crypto for the first time. Many traders use a CEX as an on-ramp and immediately withdraw to a self-custodial wallet, then use a DEX like Snake for everything else — swaps, liquidity provisioning, and exposure to long-tail tokens that never get a centralized listing.
