WHAT IT DOES

What withdraw does on Lightning Wallet

AI agents use withdraw 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 withdraw is rated Critical

This tool directly transfers money (Bitcoin via Lightning Network) out of the operator's account to external parties. This is irreversible fund movement, triggering a financial obligation/loss from the operator's perspective. Even with the operator key requirement and cooldown as mitigations, misuse by a compromised agent could drain the operator's funds. Financial category is the most severe applicable.

From the tool's definition Tool description explicitly states 'Withdraw funds from operator account to external Lightning invoice' — this moves cryptocurrency from the operator's wallet to an external recipient.
