RISK

Why get_base_call is rated Low

This tool performs a constrained query operation on the Base blockchain. It retrieves data without side effects, aligns with the 'Read' category definition (retrieves data; no side effects), and the low severity reflects minimal blast radius—a misused read-only call cannot alter state, execute arbitrary code, or cause financial harm. The bounded 4KB limit further constrains risk.

From the tool's definition Tool description explicitly states 'Bounded read-only eth_call' with a size limit of 4KB. The term 'read-only' clearly indicates no data modification, creation, or deletion occurs.
