Who controls it
WBTC tracks Bitcoin, but it is a custodial claim: BitGo holds the underlying BTC and can be compelled to act on it. Unlike BTC, it depends on an issuer.
- Holder’s claim
- WBTC is a tokenized claim intended to correspond to Bitcoin held within the WBTC custody structure.
- Redemption or sale
- Merchants burn WBTC and the custodian releases the Bitcoin through their own process. Holding the token does not let a holder redeem alone.
Dependencies
- Bitcoin custodian and merchant process
- Mint and burn administration
- Proof-of-reserve and address mapping
- Ethereum token contract
- Any protocol accepting WBTC as collateral
Advisor notes
WBTC gives Bitcoin’s price inside Ethereum applications and adds issuer, custody, contract, and protocol dependencies that native Bitcoin does not have.
A named organization or administrator controls issuance, transfers, reserves, redemption, or address restrictions. This grade can sit beside a sound reserve, a useful product, or a fitting role in a client account. It records who can act on the token and passes no judgment on the product.

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.
