ckSepoliaETHSepolia Ethereum Smart Contracts on the Internet Computer
Extending Sepolia Ethereum
Canister smart contracts on ICP can integrate with the Sepolia Ethereum testnet using a combination of replicated HTTPS outcalls to a known set of public Sepolia 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, ckSepoliaETH is a pair of canister smart contracts that utilize HTTPS outcalls and ckECDSA services. Minter and ledger contracts work together to enable users and smart contracts to send and receive SepoliaETH value within seconds for less than a cent, and no gas fees, while also always allowing users and smart contracts to send and receive SepoliaETH value to and from the Sepolia Ethereum testnet.
ckSepoliaETH 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 ckSepoliaETH support.
The pair of smart contracts work in unison to ensure that the total value of ckSepoliaETH is fully backed 1:1 by Sepolia Ether (SepoliaETH). This can always be verified by viewing the on-chain dashboards and metrics of the canisters: ckSepoliaETH Minter dashboard, ckSepoliaETH Minter metrics, ckSepoliaETH Ledger metrics.
