What Is Wrapped Bitcoin (WBTC)?
Wrapped Bitcoin (WBTC) is a tokenized representation of Bitcoin (BTC) that operates on the Ethereum (ETH) blockchain. As an ERC-20 compliant token, WBTC seamlessly integrates with Ethereum's decentralized ecosystem, including DeFi platforms, lending services, and decentralized exchanges (DEXs). Each WBTC is backed 1:1 by Bitcoin reserves, maintained by a network of verified custodians, ensuring price parity with BTC.
Launched on January 31, 2019, WBTC bridges liquidity between Bitcoin and Ethereum, enabling BTC holders to participate in Ethereum-based DeFi without selling their Bitcoin.
How Are Wrapped Bitcoin Tokens Created?
- Deposit BTC: Users send Bitcoin to a designated custodian.
- Mint WBTC: The custodian verifies the deposit and issues equivalent WBTC on Ethereum.
- Proof of Reserves: Transparent audits ensure 1:1 backing at all times.
