Struct SignOpts 

#[non_exhaustive]
pub struct SignOpts {
    pub wallet_id: String,
    pub msg_hash: [u8; 32],
    pub server_message: String,
    pub server_is_formatted: bool,
    pub secret_share: ServerKeyShare,
    pub derivation_path: Vec<u32>,
}

Options for run_sign_ecdsa. All fields required.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

wallet_id: String

Wallet id from the cached WalletProperties.

msg_hash: [u8; 32]

Pre-hashed message (32 bytes). For EVM, this is keccak256(EIP-191-prefixed message).

server_message: String

Sent in the request body. May differ from msg_hash — e.g. for EVM message signing the body carries the EIP-191 prefixed hex while the relay gets the keccak256 hash.

server_is_formatted: bool

is_formatted flag the server sees. For EVM message signing, false (server applies its own formatting).

secret_share: ServerKeyShare

The client’s MPC share for the wallet.

derivation_path: Vec<u32>

BIP-32 derivation path (for ECDSA). Use the chain’s derivation_path from mpc_config.

Implementations

impl SignOpts

pub fn new( wallet_id: impl Into<String>, msg_hash: [u8; 32], server_message: impl Into<String>, server_is_formatted: bool, secret_share: ServerKeyShare, derivation_path: Vec<u32>, ) -> Self

Trait Implementations

impl Clone for SignOpts

fn clone(&self) -> SignOpts

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SignOpts

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
