Can't be undone 1Claude Code: ask
simulate_base_transactionFREE, runs locally against Base Mainnet RPC.No findings
Why it is in this group
- The input addresses people (input.to): what it sends cannot be taken back.
Description, as the server wrote it FREE, runs locally against Base Mainnet RPC. Dry-run a transaction before sending it: eth_call + eth_estimateGas at the latest block. Predicts whether it will revert and decodes the reason (Error(string), Panic(uint256) codes, custom-error selector, or node rejection such as insufficient funds). Returns { ok, willRevert, revertReason, estimatedGas, returnData }.

read_ledgerFREE.No findings
Why it is in this group
- The name "read_ledger" says "read": a word for reading.
Description, as the server wrote it FREE. Read the attestation ledger (paginated).
This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
