RISK

Why close_cdp is rated Critical

Closing a CDP (Collateralized Debt Position) is a financial operation on a DeFi protocol that involves repaying debt and reclaiming collateral. This directly interacts with financial obligations and assets on Indigo Protocol. While the transaction requires client-side signing, the tool constructs the transaction that would execute this financial action, making it Financial category.
