FAQ

Is my calldata sent to Guardix?
Decoding runs in your browser. Nothing is posted to Guardix. If you leave the ABI and the signature blank, the page sends only the 4-byte selector in a GET request to the public Sourcify signature service.
What if the signature lookup fails?
Paste an ABI JSON array or a single function signature, then decode again.
Does a decoded call mean the transaction is safe?
The page shows function arguments only. It has no safety judgment.
