Struct HyperLiquidAuth 

pub struct HyperLiquidAuth { /* private fields */ }

HyperLiquid EIP-712 authenticator.

Handles wallet address derivation and EIP-712 typed data signing for authenticated API requests.

Implementations

impl HyperLiquidAuth

pub fn from_private_key(private_key_hex: &str) -> Result<Self>

Creates a new HyperLiquidAuth from a hex-encoded private key.

Arguments

• private_key_hex - The private key as a hex string (with or without “0x” prefix).

Returns

A new HyperLiquidAuth instance with the derived wallet address.

Errors

Returns an error if:

• The private key is not valid hex
• The private key is not exactly 32 bytes
• The private key is not a valid secp256k1 scalar

Example

use ccxt_exchanges::hyperliquid::HyperLiquidAuth;

let auth = HyperLiquidAuth::from_private_key(
    "0x1234567890abcdef1234567890abcdef1234567890abcdef1234567890abcdef"
).unwrap();
println!("Wallet: {}", auth.wallet_address());

pub fn wallet_address(&self) -> &str

Returns the wallet address (checksummed).

pub fn private_key_bytes(&self) -> &[u8; 32]

Returns the private key bytes.

Security

This method exposes the private key. Use with caution.

pub fn sign_l1_action( &self, action: &Value, nonce: u64, is_mainnet: bool, ) -> Result<Eip712Signature>

Signs an L1 action using EIP-712 typed data signing.

Arguments

• action - The action data to sign (serialized as JSON).
• nonce - The nonce (typically timestamp in milliseconds).
• is_mainnet - Whether this is for mainnet (affects chain ID).

Returns

The signature as (r, s, v) components.

pub fn sign_agent(&self, agent_address: &str) -> Result<Eip712Signature>

Signs a user agent connection request.

Arguments

• agent_address - The agent’s Ethereum address.

Returns

The signature for agent authorization.
