Module eip712 

EIP-712 typed-data hashing and signing for Derive self-custodial actions.

action_hash = keccak256(abi.encode(
    [bytes32, uint256, uint256, address, bytes32, uint256, address, address],
    [ACTION_TYPEHASH, subaccount_id, nonce, module_address,
     keccak256(module_data_abi_encoded), signature_expiry_sec, owner, signer],
))
typed_data_hash = keccak256(0x1901 || DOMAIN_SEPARATOR || action_hash)
signature = secp256k1_sign(typed_data_hash, signer_key)
