Nothing moves that you did not cap first.

SELAT is designed for agents that need paid capabilities without inheriting a drawer full of API keys, unmanaged balances, and invisible spend.

Self-custody

Payments settle from the user's own Circle Agent Wallet. SELAT does not hold keys or funds.

Caps before spend

Per-transaction, daily, weekly, and monthly limits are checked before payment leaves.

Read-only by default

Discovery, search, doctor, history, and skill listing are free and do not move funds.

Human approval

Paid calls, funding, and policy changes require explicit approval from the user.

Receipts

Each paid call is recorded so operators can reconcile spend across skills and rails.

Sandbox notes

Harness-specific constraints, including Cursor sandbox allowlisting, live in the install docs.
