cbBTC is a wrapped version of Bitcoin issued by Coinbase, backed 1:1 with real BTC held in custody. It allows Bitcoin to be used in DeFi across networks like Ethereum, Base, Solana, and Arbitrum.

cbBTC is available on DEXs like Aerodrome (Base), Orca (Solana), Uniswap V3 (Ethereum and Base), and directly through Coinbase.
