ethstaker-deposit-cli is a tool for creating EIP-2335 format BLS12-381 keystores and a corresponding deposit_data*.json file for Ethereum Staking Launchpad. One can also provide a keystore file to generate a signed_exit_transaction*.json file to be broadcast at a later date to exit a validator.
Please read Launchpad Validator FAQs before generating the keys.
You can find the audit report by Trail of Bits of the original staking-deposit-cli here. The audit of the updated ethstaker-deposit-cli is forthcoming.
Ethstaker confirms the canonical Ethereum staking deposit contract addresses and launchpad URLs. Please be sure that your ETH is deposited only to this deposit contract address, depending on chain.
Depositing to the wrong address will lose you your ETH.
