WBTC Smart Contract on the Internet Computer
Extending WBTC
Canister smart contracts on ICP can integrate with the Ethereum network using a combination of replicated HTTPS outcalls to a known set of public Ethereum nodes to read state and submit transactions, and chain-key ECDSA (ckECDSA) signatures, an enhanced version of threshold ECDSA, to sign those submitted transactions.
Building upon this integration framework, ckWBTC is a pair of canister smart contracts that utilize HTTPS outcalls and ckECDSA services. The ckETH minter and ckWBTC ledger contracts work together to enable users and smart contracts to send and receive WBTC value within seconds with negligible transaction fees, and no gas fees, while also always allowing users and smart contracts to send and receive WBTC value to and from the Ethereum network.
ckWBTC exposes ICRC-1 and ICRC-2 ledger interfaces (the fungible token standards of ICP), making it simple for all wallets on the Internet Computer to offer ckWBTC support.
The pair of smart contracts work in unison to ensure that the total value of ckWBTC is fully backed 1:1 by WBTC. This can always be verified by viewing the on-chain dashboards and metrics of the canisters: ckETH Minter dashboard, ckETH Minter metrics, ckWBTC Ledger metrics.
