Paste a crypto wallet signature into Claude before you sign it
A prompt for checking what you are about to sign: paste the message, contract address, function and amounts plus what you think you're doing, and Claude explains it in plain English, checks for unlimited approvals, setApprovalForAll and Permit/Permit2 signatures, compares it with your intent and gives a verdict of normal, ask more questions, or don't sign.

What they did
A prompt for checking what you are about to sign: paste the message, contract address, function and amounts plus what you think you're doing, and Claude explains it in plain English, checks for unlimited approvals, setApprovalForAll and Permit/Permit2 signatures, compares it with your intent and gives a verdict of normal, ask more questions, or don't sign.
Result (as claimed)
Most wallet drains start with one signature people didn't understand.
Tools they used
Cost: Pricing depends on the tools you pick; check each official pricing page.
Set it up
Gather the documents
Collect statements, bills, invoices or tax documents for the period you want reviewed.
Ask for an audit, not actions
Have Claude list findings, amounts and suggested next steps before it does anything.
Approve each action
Approve cancellations, disputes or payments one at a time. Never give an agent open-ended access to move money.
Track the result
Record what changed and what you saved so you can check it next month. This is not financial advice.
Copy the full setup prompt
Paste into your agent and it will walk you through the setup, asking before anything that sends, posts or spends.
