AI agents use strato.lending.withdraw-collateral-max to commit financial operations through Griphook — usually the final step of a payment, billing, or trading workflow. A call moves real money.
Withdrawing collateral from a lending/DeFi protocol is a financial operation that moves assets out of a collateral position. 'Maximum available' amplifies the blast radius — an AI agent misusing this tool could withdraw all collateral, potentially triggering liquidations or destabilizing lending positions. This directly involves financial asset movement in a DeFi ecosystem.
