Module: hyperliquid/signing

Source: hyperliquid/signing.rs

Minimal, vector-tested primitives for Hyperliquid L1-action signatures.

This covers the EIP-712 envelope and the narrow limit-order action shape needed by the first execution path. Each wire representation is fixed by a protocol test vector before it becomes usable by an adapter.

Functions

pub fn limit_order_connection_id

#![allow(unused)]
fn main() {
pub fn limit_order_connection_id(...) { ... }
}

Hashes the exact MessagePack limit-order action accepted by Hyperliquid. This intentionally supports only an IOC, non-reduce-only order with no client ID or builder. Broader action variants must add their own vectors, rather than sharing a permissive serializer with different semantics.

pub fn cancel_connection_id

#![allow(unused)]
fn main() {
pub fn cancel_connection_id(...) { ... }
}

Hashes the exact single-order cancel action accepted by Hyperliquid.

pub fn l1_action_signing_digest

#![allow(unused)]
fn main() {
pub fn l1_action_signing_digest(...) { ... }
}

Returns the EIP-712 digest the wallet must sign for a canonical L1 action connection ID. The protocol uses source a on mainnet and b on testnet.

pub fn sign_l1_action

#![allow(unused)]
fn main() {
pub fn sign_l1_action(...) { ... }
}

Signs a canonical L1 action connection ID using Ethereum’s r || s || v shape. v is normalized to 27 or 28 for the exchange API.
