Why cross_swap is rated Critical
This tool moves cryptocurrency assets across different blockchains, which constitutes a financial operation. Cross-chain transfers are irreversible and involve real monetary value. Misuse by an AI agent could result in permanent loss of funds sent to wrong addresses or chains, or unauthorized transfers of crypto assets. Financial is the most severe applicable category given it directly moves tokens/funds.
