Wrapped Bitcoin (wBTC) is an innovative financial instrument that bridges the two largest cryptocurrencies: Bitcoin and Ethereum. Launched in 2019, wBTC is an ERC-20 token on the Ethereum blockchain that mirrors Bitcoin's (BTC) value, enabling interoperability between Bitcoin and Ethereum-based decentralized applications (DApps). Each wBTC maintains a 1:1 peg with BTC, ensuring equivalent value.
How Does wBTC Work?
wBTC operates through a meticulous minting process involving multiple stakeholders:
- Users initiate conversion by contacting wBTC merchants.
- Merchants facilitate transactions after completing AML/KYC checks.
- Custodians (e.g., BitGo Trust) mint wBTC upon authorization, securing BTC reserves in auditable vaults.
- DAO Governance oversees smart contract updates and participant management.
