Connection Setup

Step 1: Connect Your Wallet​

  1. Go to sigmaengine.io
  2. Click Connect Wallet in the top right
  3. Sign the login message with your wallet (MetaMask, Rabby, Phantom, etc.)
  4. Your wallet address is your account — no email or password needed

Step 2: Connect an Exchange​

Navigate to Connections in the sidebar. Select your exchange and follow the steps for your specific exchange below.

All credentials are encrypted at rest using Fernet (AES-128-CBC + HMAC-SHA256). Your main wallet private key is never shared with Sigma Engine unless a specific exchange requires it for session creation (in which case it is only used locally to sign, never stored in plaintext).

DEX Connections​

  1. Sign up at app.ethereal.trade if you haven't already
  2. On the Connections page, click "Connect" on the Ethereal card
  3. Approve the authorization message in your wallet (MetaMask, Rabby, etc.)
  4. A linked signer is created automatically — your private key is never shared

No API keys needed. The linked signer can only place and cancel orders. It cannot withdraw or transfer funds.

Revoking Access​

You can disconnect any exchange at any time:

  • API Keys: Delete the key on the exchange, or disconnect on Sigma Engine

Both methods immediately prevent Sigma Engine from placing orders on that exchange.
