signed_call

Execute signed encrypted eth_call

Execute a signed read with encrypted calldata.

Signatures

# sync
w3.seismic.signed_call(
    *,
    to: ChecksumAddress,
    data: HexBytes,
    value: int = 0,
    gas: int = 30_000_000,
    security: SeismicSecurityParams | None = None,
    eip712: bool = False,
) -> HexBytes

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

Parameters

Parameter	Type	Default	Description
to	ChecksumAddress	Required	Contract address to call
data	HexBytes	Required	Plaintext calldata (SDK encrypts it)
value	int	0	Wei to include in the call context
gas	int	30_000_000	Gas limit
security	SeismicSecurityParams | None	None	Override default security parameters
eip712	bool	False	Use EIP-712 typed-data signing path

Returns

HexBytes — decrypted response bytes. Empty RPC result ("0x") returns HexBytes(b"").

Example

raw = w3.seismic.signed_call(to="0xTarget", data=calldata)
if raw:
    print(raw.hex())

Notes

• Does not modify blockchain state — this is a read-only eth_call

• Both request and response are encrypted end-to-end (calldata, function selector, arguments, and the returned data)

• Does not increment your account nonce

• For contract interactions, prefer contract.read.functionName(...) which handles ABI encoding/decoding automatically
