## Why opt_out_rewards is rated Critical

Opting out of rewards on a financial blockchain protocol constitutes a financial action that forfeits or waives pending monetary rewards. On a stablecoin/payment blockchain (Tempo), rewards represent real financial value. Misuse could cause an AI agent to irreversibly forfeit accumulated rewards on behalf of a user.

From the tool's own definition: "'Opt out of rewards for a TIP-20 token' and 'any pending rewards will be' (description appears truncated) — this action affects financial reward claims on a stablecoin payments blockchain"

## Use case

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