WHAT IT DOES

What intentApprove does on Agentek Eth

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

RISK

Why intentApprove is rated Critical

Approving token spending on Ethereum grants an external contract or address the ability to transfer tokens on behalf of the user. This is a financial operation with significant risk — a malicious or incorrect approval can lead to complete loss of the approved token amount. It falls under Financial as it directly enables financial transactions/obligations on-chain.
