A batch payout is many transfers submitted as one operation: a payroll run, a marketplace's seller settlements, an airdrop to thousands of wallets. The batch groups by network so one signature covers every leg on a chain, and each transfer confirms independently with its own transaction ID.
The economics favor it exactly where doing transfers one-by-one hurts: many small legs on one cheap network. The discipline that makes it safe is list hygiene - per-row validation on entry and a preview before signature.
Send on U.CASH takes batch lists pasted or by API, validates addresses per network, previews every leg with its fee, and exports a settlement report for reconciliation. The payouts guide walks the full flow.
Every term behind the rails, the assets, and the settlement.
