The control finding
Coinbase-issued Bitcoin wrapper. Coinbase holds the underlying BTC and can freeze the token.
- Holder’s position
- The holder owns a token representing Coinbase's obligation to redeem 1:1 for BTC, not Bitcoin itself.
- Redemption or exit
- Eligible Coinbase customers mint or redeem cbBTC for BTC directly through Coinbase. Holders on other venues exit through markets instead.
Dependencies an advisor should record
- Coinbase custody and jurisdiction
- Coinbase's mint, burn, and freeze authority
- The token contract and any bridge across chains
- Market liquidity for the peg
Why this distinction matters
A client who wants Bitcoin's censorship resistance does not get it through cbBTC. The wrapper substitutes Coinbase's custodial and regulatory exposure for Bitcoin's own settlement guarantees.
A named organization or administrator controls issuance, transfers, reserves, redemption, or address restrictions. That finding can coexist with a sound reserve, useful product, or appropriate client role. The grade prevents the on-chain wrapper from being mistaken for the absence of an administrator.
Questions before use
- Does the exact contract and chain match the instrument reviewed here?
- Which party can mint, burn, pause, upgrade, block, or redeem?
- Does the client have direct redemption access or only secondary liquidity?
- What protocol, bridge, wallet, and custodian dependencies are added?
- Which event would force review or exit?

Legend: No freeze key: no issuer or administrator can freeze an address at this layer · Governed, no freeze: on-chain collateral and governance set the terms, but no issuer blocklist exists · Mixed control: on-chain mechanisms sit beside custodians, real-world assets, a central transaction orderer, or other parties a court or regulator can compel · Issuer can freeze: a named organization or administrator controls issuance, transfers, reserves, redemption, or address restrictions.
