what is cbbtc?

cbBTC is Coinbase’s wrapped version of Bitcoin, issued on Base at a 1:1 ratio with native BTC. It allows BTC holders to use their Bitcoin directly in Base’s DeFi ecosystem.

Coinbase is the sole issuer and custodian of cbBTC. All reserves are securely held in Coinbase’s custody, and supply is matched transparently with onchain attestations.

cbBTC is an ERC-20 token on Base. Each token is fully backed by Bitcoin reserves, and the backing is proven through public attestations published by Coinbase.

cbBTC leverages Coinbase’s custody infrastructure and regular third-party attestations. This ensures that every cbBTC in circulation is verifiably backed and that users have transparency into reserves at all times.
