Approval model: separate account

Separate account

What it means: the broker gives the agent its own account (or portfolio) and enforces that orders only happen there. Your other money is out of reach for trading, though the agent may still be able to read other accounts.

What it does not mean: it does not, on its own, require approval for each order.

Examples

• Robinhood: outside agents trade only in a Robinhood Agentic account,¹ which holds only the funds you deposit into it.² The agent can still read all of your Robinhood accounts.¹
• Coinbase: you pick which portfolios the agent can reach on the approval screen.³ This is optional; the agent can also use the main account.⁴ Isolated agent portfolios are limited to spot crypto.⁵

Builder notes

• Check read scope separately from trade scope. A separate trading account does not mean separate read access.
• Fund the account with an amount you accept losing to a bad prompt or a bug.
