# Use Cases

> When TESA makes sense

* **Idle operating cash:** the balance that sits idle between payment cycles starts earning yield without losing availability.
* **Centralized treasury:** companies that concentrate their dollar cash in a single structure get allocation by approved policy, without building their own desk.
* **Dollar reserve:** companies that hold a USDC reserve for FX reasons capture the Treasury rate on that reserve.
* **Startup runway:** cash raised in a funding round earns yield while it is spent, with daily redemptions for payroll and suppliers.

In every case the requirement is the same: digital dollar cash, a centralized treasury and meaningful volume.
