# Scoped & Expiring Grant

The root authority is **not** a blanket approval. It is a single EIP-7715 execution permission, scoped tightly along three axes.

* **Per token** — an `erc20-token-periodic` permission for USDC only
* **Per period** — sized `budget + fee headroom`, reset on a 24-hour period
* **Expiring** — a 1-hour expiry on the grant itself

The grant is signed off-chain (EIP-712, no gas). The returned context is decoded with `decodeDelegations` into the signed root delegation that seeds the whole chain. Because the grant is periodic and short-lived, even an unused permission lapses on its own.

> A scoped, expiring grant is the difference between "spend up to X of one token this hour" and "spend anything, forever."
