How exchanges are ranked

CEX rankings combine valid native-asset spot volume, trust, liquidity, spread, freshness and market coverage. DEX rankings use chain-specific spot volume and available on-chain validation. Stale, anomalous, leveraged and low-quality markets are excluded. Affiliate relationships never affect rankings. Markets and regional availability change frequently, so confirm availability before trading.
