WHAT IT DOES

What estimateGasCost does on Agentek Eth

AI agents call estimateGasCost to retrieve information from Agentek Eth without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why estimateGasCost is rated Low

This tool only reads/estimates data about gas costs; it does not execute transactions, write to blockchain state, delete data, or commit financial obligations. The estimation is informational and has no side effects on the blockchain or user's assets.

From the tool's definition The tool is described as 'Estimate the gas cost for a transaction' — it performs a calculation/query operation that retrieves information about hypothetical transaction costs without executing any actual transactions, modifying state, or moving funds.
