    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Verify a Base (Ethereum L2) transaction and report every USDC Transfer event in it: sender, recipient, amount, block number, on-chain success, and confirmation age. Free, no account, reads Base's public JSON-RPC live. Example you can call right now, no setup: {"tx": "0xad887d8844d9d8b093b8040c1950e66b7cf3c9f3c98644bed7fb911c6a2e8079"} -- a real, already-settled USDC transfer, always returns found:true.

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.
