UnsignedSeismicTx

Complete unsigned Seismic transaction

All fields of a TxSeismic (type 0x4a) transaction before signing.

Definition

@dataclass(frozen=True)
class UnsignedSeismicTx:
    chain_id: int
    nonce: int
    gas_price: int
    gas: int
    to: ChecksumAddress | None
    value: int
    data: HexBytes
    seismic: SeismicElements

Fields

Field	Type	Description
chain_id	int	Numeric chain identifier
nonce	int	Sender's transaction count
gas_price	int	Gas price in wei
gas	int	Gas limit
to	ChecksumAddress | None	Recipient address, or None for contract creation
value	int	Amount of wei to transfer
data	HexBytes	Encrypted calldata (ciphertext)
seismic	SeismicElements	Seismic-specific encryption and expiry fields

Example

from seismic_web3 import sign_seismic_tx_eip712, PrivateKey

unsigned_tx = UnsignedSeismicTx(...)

signed_tx = sign_seismic_tx_eip712(unsigned_tx, PrivateKey(...))
tx_hash = w3.eth.send_raw_transaction(signed_tx)

Notes

• The data field contains encrypted calldata — plaintext is not recoverable without the TEE's private key

• Created automatically by the SDK's write methods; visible in DebugWriteResult for inspection

• Compatible with both raw signing (message_version=0) and EIP-712 (message_version=2)
