Functions

func EncodePrivKey

func EncodePrivKey(priv *ecdsa.PrivateKey) hexutil.Bytes

EncodePrivKey encodes the given private key in 32 bytes

func EncodePrivKeyToString

func EncodePrivKeyToString(priv *ecdsa.PrivateKey) string

func PrivateKeySignerFn

func PrivateKeySignerFn(key *ecdsa.PrivateKey, chainID *big.Int) bind.SignerFn

Types

type SignerFactory

type SignerFactory func(chainID *big.Int) SignerFn

SignerFactory creates a SignerFn that is bound to a specific ChainID

func SignerFactoryFromConfig

func SignerFactoryFromConfig(l log.Logger, privateKey, mnemonic, hdPath string, signerConfig opsigner.CLIConfig) (SignerFactory, common.Address, error)

SignerFactoryFromConfig considers three ways that signers are created & then creates single factory from those config options. It can either take a remote signer (via opsigner.CLIConfig) or it can be provided either a mnemonic + derivation path or a private key. It prefers the remote signer, then the mnemonic or private key (only one of which can be provided).

type SignerFn

type SignerFn func(context.Context, common.Address, *types.Transaction) (*types.Transaction, error)

SignerFn is a generic transaction signing function. It may be a remote signer so it takes a context. It also takes the address that should be used to sign the transaction with.

func SignerFnFromBind

func SignerFnFromBind(fn bind.SignerFn) SignerFn
