WHAT IT DOES

What claim_promo does on Lightning Wallet

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

RISK

Why claim_promo is rated Critical

This tool triggers a financial claim of 100 satoshis (Bitcoin), which is a real monetary action. Even though it's a promo/freebie, it commits a financial obligation on the provider's side and moves funds into the operator's wallet. It falls squarely under Financial as it involves Bitcoin value transfer.

From the tool's definition 'Claim the free-sats install promo (100 sats)' — directly claims Bitcoin (sats) into the wallet, constituting a financial transaction that moves monetary value.
