Wrapped Bitcoin (WBTC) is an Ethereum token that is intended to represent Bitcoin (BTC) on the Ethereum blockchain. It is not Bitcoin, but rather a separate ERC-20 token that’s designed to track Bitcoin’s value. WBTC was created to allow Bitcoin holders to participate in decentralized finance (“DeFi”) apps that are popular on Ethereum. Through a WBTC partner, 1 Bitcoin can be exchanged for 1 Wrapped Bitcoin, and vice-versa. The BTC that backs WBTC is verifiable through a “proof of reserve” system that verifies the 1:1 backing between minted WBTC tokens and Bitcoin stored by custodians. WBTC is maintained by a group called the WBTC DAO that consists of over 30 members. It was originally started by BitGo, Ren, and Kyber.
