Understand CEXs, DEXs, custody, order books, AMMs, swaps, slippage and how to evaluate major exchange examples without treating popularity as a recommendation.
A centralized exchange is operated by a company. Users usually create an account and may deposit assets into wallets controlled by the platform.
A decentralized exchange typically lets users connect a wallet and interact with smart contracts to swap assets on-chain.
An order book records bids and asks. A matching engine can pair compatible orders according to the platform’s rules.
Many DEXs use automated market makers where liquidity is supplied to pools and pricing is determined by protocol formulas or concentrated-liquidity designs.
Binance, Bybit, OKX, Coinbase and Kraken are major names beginners may encounter. Rankings vary by date, methodology and jurisdiction.
Uniswap, PancakeSwap, Curve, Jupiter and Aerodrome are examples across different chains and use cases.
On a custodial exchange, your account may represent a claim on assets held by the platform. In self-custody, your keys directly authorize blockchain transactions.
Trading costs can include exchange fees, network fees, spread and price impact. Slippage is the difference between an expected execution price and the actual price.
Use strong unique authentication, hardware security where appropriate, withdrawal protections and careful device hygiene.
Before using any exchange, check legal availability in your country, custody, fees, liquidity, withdrawal rules, security history, support and the exact official domain.
Before moving money, connecting a wallet, trusting a claim or signing a transaction, slow down. Identify the exact asset, network, contract, source, permissions and risks.
