Wrapped Bitcoin

Definition

Wrapped Bitcoin, often abbreviated as WBTC, is a tokenized representation of Bitcoin on a different blockchain network, typically Ethereum. It allows Bitcoin holders to utilize their assets within decentralized finance (DeFi) applications that operate on other smart contract platforms. Each WBTC token is backed 1:1 by actual Bitcoin held in reserves, managed by a custodian. This mechanism facilitates interoperability, extending Bitcoin’s utility beyond its native chain.
