Privacy & Security

Spectre allows you to trade with Stealth Orders. Unlike typical exchanges where your static wallet address is visible, Stealth Orders use a unique, ephemeral address for every transaction. This breaks the linkability between your trades and your master identity. This is achieved using the Arcane protocol.

How it Works

Stealth Keys: You have a “Scanning Key” (to find your trades) and a “Spending Key” (to sign trades).
Ephemeral Address: When placing an order, you generate a random “Stealth Address” that only you can control.
Metadata: You attach stealthData (ephemeral public key, view tag) to the order so you can recover it later.

Generating Stealth Data

You must include the stealthData parameter in spectre_placeOrder to enable privacy.

Usage

Python
TypeScript

from arcane.wallet import ArcaneWallet
from arcane.core import get_stealth_data

# 1. Initialize your wallet
# In reality, load this securely!
my_priv_key = "0x..." 
wallet = ArcaneWallet(my_priv_key)

# 2. Get your master Stealth Address (starts with 0X0)
my_address = wallet.get_address()
# e.g., "0X0..."

# 3. Generate Stealth Data for a SELF-transfer (trading with yourself essentially)
# For an exchange, you are designating yourself as the owner of the order.
# The `get_stealth_data` function generates the ephemeral keys.
stealth_tx = wallet.get_stealth_data(my_address)

# This dictionary matches the API requirement
stealth_data_param = {
    "ephemeralPublicKey": stealth_tx["ephemeral_public_key"],
    "viewTag": stealth_tx["view_tag"],
    "stealthPublicKey": stealth_tx["stealth_public_key"],
    # Client ID is optional, but helps you filter your own orders quickly
    # "clientId": "my-client-id" 
}

print("Stealth Param for API:", stealth_data_param)

# 4. Use in API
# rpc.call("spectre_placeOrder", { ..., "stealthData": stealth_data_param })

import { ArcaneWallet } from '@0x0exchange/arcane-sdk';

// 1. Initialize
const privateKey = "0x...";
const wallet = new ArcaneWallet(privateKey);

// 2. Get Address
const myAddress = wallet.getAddress();

// 3. Generate Stealth Data
const stealthTx = wallet.getStealthData(myAddress);

const stealthDataParam = {
    ephemeralPublicKey: stealthTx.ephemeralPublicKey,
    viewTag: stealthTx.viewTag,
    stealthPublicKey: stealthTx.stealthPublicKey
};

console.log("Stealth Param:", stealthDataParam);

Client Viewing Keys

To view your trade history or decrypt your order details on a new device, you need your Viewing Key.

This key allows Read-Only access.
It cannot sign transactions or move funds.
The exchange uses this to serve you your encrypted data.

Encryption (ECIES)

Sensitive fields in OrderMeta are encrypted using ECIES (Elliptic Curve Integrated Encryption Scheme).

Encryption: Done with the Viewing Public Key.
Decryption: Done with the Viewing Private Key.

This ensures that even if the exchange database is leaked, your private order details (like exact leverage, margin, or identity) remain cryptographically secure.
