RISK

Why send_payment is rated Critical

This tool directly moves financial assets (USDC stablecoin) on-chain. Misuse by an AI agent could result in irreversible loss of funds. On-chain transactions are permanent and cannot be reversed, making this both Financial and highly critical in blast radius.

From the tool's definition 'Send USDC to another agent on Base L2' and 'All payments are on-chain' — this tool transfers cryptocurrency (USDC) on a blockchain network.
