Is Extended safe to connect to an AI agent?
Can trade unattended. Safety 43%
What an AI agent can do
- Live vs paper: live; Sepolia testnet with daily test USDC source
- Order approval: Official Python SDK ships an experimental MCP server (production by default). The API key is read-only, but the Stark key every order needs can also withdraw and transfer; up to 10 sub-accounts per wallet source
- Markets: crypto perpetuals, RWA perpetuals
- Pricing: no API fee; 0% maker / 0.025% taker on standard markets
Safeguards that exist
- Order approval or confirmation options: No per-order approval; a dead-man's switch and per-market order and position caps (official docs) source
- Paper, demo or testnet mode: Sepolia testnet with daily test USDC (official docs) source
- Scoped keys, permission scopes or IP whitelisting: Up to 10 sub-accounts per wallet, each with its own API key and Stark key (official docs) source
Safeguards that are missing
- Can it place live orders unattended?: API orders execute with no per-order approval step source
- Withdrawal permission needed or allowed: The Stark key every order needs can also withdraw and transfer (official docs) source
- Open source or audited: Audits cover the earlier Starknet contracts; none found yet for the Arc settlement contracts (migrated 2026-10-22) (official docs) source
