Paying employees, contractors, and suppliers at scale, with predictable throughput, predictable cost, and privacy for sensitive amounts. ## The problem High-volume stablecoin disbursements hit per-transaction throughput limits on shared chains. Costs fluctuate with network congestion, so a payroll run that cleared cheaply yesterday can spike today. On top of that, salary and supplier amounts are publicly visible to anyone watching the chain, which leaks commercially sensitive data. ## How Stable addresses it * **The USDT transfer aggregator batches high-volume transfers into parallelized settlement bundles**, so a single run isn't bottlenecked by per-transaction overhead. See [USDT transfer aggregator](/en/explanation/usdt-transfer-aggregator). * **Guaranteed blockspace gives enrolled partners reserved capacity in every block**, so inclusion and cost stay predictable regardless of what else the network is doing. See [Guaranteed blockspace](/en/explanation/guaranteed-blockspace). * **Confidential transfer shields amounts using zero-knowledge cryptography**, so payroll and supplier runs don't publish sensitive numbers on-chain. See [Confidential transfer](/en/explanation/confidential-transfer). ## Next recommended Understand how high-volume USDT0 transfers batch into parallelized settlement bundles. See how enrolled partners secure reserved capacity in every block. Review how ZK cryptography shields transfer amounts while keeping parties auditable.
