WHAT IT DOES

What pause_token does on Tempo

AI agents use pause_token to commit financial operations through Tempo, usually the final step of a payment, billing, or trading workflow. A call moves real money.

RISK

Why pause_token is rated Critical

Pausing all transfers on a payment token halts all financial activity for that token across all users. This is a high-impact financial operation that can freeze funds and prevent any transactions from occurring, representing a critical blast radius. It is irreversible in effect until unpaused, and operates on a financial instrument (stablecoin payments).
