Automatically consolidates and transfers available balances from multiple beneficiary accounts to a designated destination account in a single operation. This is commonly used for treasury management, revenue collection, or balance consolidation. You can sweep all beneficiaries or specify a subset. The destination can be a master account, external bank account, or cryptocurrency wallet. Sweep operations are atomic - either all transfers succeed or all fail. Useful for end-of-day settlements, collecting marketplace fees, or pooling funds.
