WHAT IT DOES

What claim_rewards does on Tempo

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

RISK

Why claim_rewards is rated Critical

Claiming rewards initiates a real-world financial transaction that moves token assets into a wallet. Given this is on a stablecoin payments platform designed for autonomous financial operations, this constitutes a financial action with high blast radius if misused (e.g., draining reward pools or claiming rewards not belonging to the agent).

From the tool's definition 'Claim all pending rewards for a TIP-20 token. Rewards are sent to your wallet' — this triggers a financial transfer of reward tokens to a wallet.
