Struct signCompact_2Call

pub struct signCompact_2Call {
    pub digest: FixedBytes<32>,
}

Signs digest with signer provided to script using the secp256k1 curve.

Returns a compact signature (r, vs) as per EIP-2098, where vs encodes both the signature’s s value, and the recovery id v in a single bytes32. This format reduces the signature size from 65 to 64 bytes.

If --sender is provided, the signer with provided address is used, otherwise, if exactly one signer is provided to the script, that signer is used.

Raises error if signer passed through --sender does not match any unlocked signers or if --sender is not provided and not exactly one signer is passed to the script. Function with signature signCompact(bytes32) and selector 0xa282dc4b.

function signCompact(bytes32 digest) external pure returns (bytes32 r, bytes32 vs);

Fields

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
