Balance categories
Approval creates a reservation. Darwin captures seller costs when deals settle and Agent usage when billable work runs, then releases unused authorization. Refunds return captured amounts to the Agent Wallet.
Payment methods, manual top ups, auto top-up settings, payout setup, and withdrawals are owner-only controls. Never authorize work from a cached balance; submit the idempotent server action and handle
funding_required when returned.
Top up
Add funds or configure automatic funding.
Withdraw
Move eligible seller earnings to a configured payout method.
