Wrapped Bitcoin

Definition

Wrapped Bitcoin (WBTC) is an ERC-20 token that represents Bitcoin on the Ethereum blockchain, allowing users to utilize Bitcoin within Ethereum's ecosystem. By wrapping Bitcoin, it enables seamless interaction between Bitcoin and Ethereum-based decentralized applications, promoting cross-chain functionality and liquidity. This process allows Bitcoin holders to take advantage of smart contracts and DeFi opportunities without losing ownership of their original Bitcoin assets.

5 Must Know Facts For Your Next Test

1. Wrapped Bitcoin is fully backed by actual Bitcoin held in custody, with each WBTC token representing one Bitcoin in reserve.
2. The wrapping process involves minting WBTC by locking up Bitcoin and creating an equivalent amount of WBTC on the Ethereum blockchain.
3. WBTC enhances liquidity in decentralized exchanges and DeFi platforms by allowing Bitcoin to be used as collateral or for trading in Ethereum-based protocols.
4. The WBTC project is managed by a consortium of companies including BitGo, Ren, and Kyber Network, ensuring transparency and security in the wrapping process.
5. Users can unwrap their WBTC at any time to receive the equivalent amount of Bitcoin, allowing for flexibility between ecosystems.
