Wrapped Rootstock Bitcoin

rBTC is the most secure and decentralized form of Bitcoin in DeFi. It is the native token of Rootstock, Bitcoin’s DeFi Layer. Each rBTC is pegged 1:1 to BTC through the PowPeg, a decentralized, non-custodial two-way bridge secured by Bitcoin’s Proof-of-Work through merge mining. Unlike wrapped Bitcoin tokens relying on centralized custodians, rBTC enables DeFi interactions in a trust-minimized way.

WRBTC is an ERC20 token that wraps rBTC. Both are on the same network, Rootstock. This is accomplished using a smart contract. It is a 1:1 equivalent of RBTC. WRBTC allows access to DeFi on Rootstock and on other EVM chains.
