Validator Deposit Contract Local Copy

This package contains a copy of the official Ethereum Validator Deposit Contract along with its ABI, bytecode, and Go bindings generated by go-ethereum's abigen version 1.10.4-stable. It contains useful test harnesses for setting up and deploying a validator deposit contract using Go bindings, which are used across tests in Prysm.

Functions

func DepositInput 

func DepositInput(depositKey, withdrawalKey bls.SecretKey, amountInGwei uint64) (*ethpb.Deposit_Data, [32]byte, error)

DepositInput for a given key. This input data can be used to when making a validator deposit. The input data includes a proof of possession field signed by the deposit key.

Spec details about general deposit workflow: 

To submit a deposit:

- Pack the validator's initialization parameters into deposit_data, a Deposit_Data SSZ object.
- Let amount be the amount in Gwei to be deposited by the validator where MIN_DEPOSIT_AMOUNT <= amount <= MAX_EFFECTIVE_BALANCE.
- Set deposit_data.amount = amount.
- Let signature be the result of bls_sign of the signing_root(deposit_data) with domain=compute_domain(DOMAIN_DEPOSIT). (Deposits are valid regardless of fork version, compute_domain will default to zeroes there).
- Send a transaction on the Ethereum 1.0 chain to DEPOSIT_CONTRACT_ADDRESS executing `deposit(pubkey: bytes[48], withdrawal_credentials: bytes[32], signature: bytes[96])` along with a deposit of amount Gwei.

func UnpackDepositLogData 

func UnpackDepositLogData(data []byte) (pubkey, withdrawalCredentials, amount, signature, index []byte, err error)

func VerifyDepositSignature

func WithdrawalCredentialsHash 

func WithdrawalCredentialsHash(withdrawalKey bls.SecretKey) []byte

withdrawal_credentials[:1] == BLS_WITHDRAWAL_PREFIX_BYTE
withdrawal_credentials[1:] == hash(withdrawal_pubkey)[1:]

where withdrawal_credentials is of type bytes32.
