Wrapped Bitcoin WBTC
Bitcoin-backed token.
Wrapped Bitcoin represents bitcoin through a token usable on other networks. WBTC is separate from BTC held on Bitcoin.
What is Wrapped Bitcoin?
WBTC’s design uses bitcoin held in custody to back tokens issued on supported networks. Its original framework targets one bitcoin per token, with merchants and custodians coordinating issuance and redemption. This adds custody and token-contract dependencies.
Backing and redemption depend on custody and service arrangements. A matching ticker or logo does not verify a token contract, and a target backing ratio is not a guarantee.
