Coinbase Bridge vs CoWSwap

cbBTC is Coinbase’s wrapped Bitcoin launched on Base and Ethereum to simplify DeFi access for exchange users. Custody is handled by Coinbase Prime with a daily on‑chain proof‑of‑reserve attestation signed by Deloitte. cbBTC is fungible 1:1 with native BTC and charges zero conversion fees during promotional periods.

CoW Swap is a decentralized exchange interface built on CoW Protocol, an intent-based meta-DEX aggregator that optimizes trades through batch auctions and a competitive network of solvers. Instead of executing swaps directly on-chain, users sign trade intents that are aggregated and matched via Coincidence of Wants (CoWs) or routed across multiple liquidity sources to achieve the best price. This architecture reduces slippage, captures price improvements, and protects users from Maximal Extractable Value (MEV). CoW Swap combines peer-to-peer matching with aggregated liquidity, enabling efficient, secure, and gas-optimized trading across multiple EVM networks.
