Signatures

# sync
w3.seismic.deposit(
    *,
    node_pubkey: bytes,
    consensus_pubkey: bytes,
    withdrawal_credentials: bytes,
    node_signature: bytes,
    consensus_signature: bytes,
    deposit_data_root: bytes,
    value: int,
    address: str = DEPOSIT_CONTRACT_ADDRESS,
) -> HexBytes

# async
await w3.seismic.deposit(...same args...) -> HexBytes

Required byte lengths

Parameter	Length
node_pubkey	32
consensus_pubkey	48
withdrawal_credentials	32
node_signature	64
consensus_signature	96
deposit_data_root	32

ValueError is raised on length mismatch.

Example

tx_hash = w3.seismic.deposit(
    node_pubkey=node_pubkey,
    consensus_pubkey=consensus_pubkey,
    withdrawal_credentials=withdrawal_credentials,
    node_signature=node_signature,
    consensus_signature=consensus_signature,
    deposit_data_root=deposit_data_root,
    value=32 * 10**18,
)

Notes

• Uses transparent eth_sendTransaction semantics — deposit data is public, not shielded

• value is deposit amount in wei (typically 32 * 10**18 for a full validator)

• All parameters are keyword-only to prevent mix-ups between the many bytes arguments
