1. Connect your main wallet here in the browser. It signs setup transactions only.
2. The engine generates a session key and keeps it encrypted on disk. It is never shown here, never sent over this API, and never written to the database.
3. You send that key a small amount of MON for gas, and deposit trading collateral to its MarginAccount balance.
4. The engine quotes with the session key. Your main wallet stays cold, and closing this browser does not stop the bot.

MarginAccount is CROSS-MARKET: one balance backs every pair, so there is no risk isolation between markets. Use a separate session key per risk bucket if you want isolation.

No session key yet. The engine generates it locally; you never see or handle the secret.

Requires SESSION_PASSPHRASE (8+ chars) in the engine environment.
