Signature

ECDSA signature components

ECDSA signature components for signed Seismic transactions.

Definition

@dataclass(frozen=True)
class Signature:
    v: int
    r: int
    s: int

Fields

Field	Type	Description
v	int	Recovery identifier (0 or 1, y-parity)
r	int	First 32-byte integer of the signature
s	int	Second 32-byte integer of the signature

Example

from eth_keys import keys as eth_keys
from seismic_web3 import Signature, PrivateKey

sk = eth_keys.PrivateKey(bytes(PrivateKey(...)))
sig_obj = sk.sign_msg_hash(b"\xab" * 32)

sig = Signature(v=sig_obj.v, r=sig_obj.r, s=sig_obj.s)

Notes

• v is 0 or 1 (EIP-155 y-parity), not the legacy 27/28 values

• Typically created internally by signing functions — most users won't construct this directly
