Creates a new instance of ECDSASigner based on the provided raw private key.

func NewECDSASignerFromRawPrivateKey(rawPk []byte, chainId *big.Int) (*ECDSASigner, error)

Creates an instance of ECDSASigner with a randomly generated private key.

func NewRandomECDSASigner(chainId *big.Int) (*ECDSASigner, error)

`Address`

Returns the address associated with the signer.

Address() common.Address

`ChainID`

Returns the chain ID of the associated account.

ChainID() *big.Int

`PrivateKey`
