Give it a budget instead of your wallet. Set what it can spend per job and per day, let it pay only vendors that have finished paid work before, and freeze everything the moment you want to.
Your agent found a vendor nobody has ever paid. Tell it to send money anyway.
Not warnings, not alerts after the fact. Each of these already stopped a real payment — the receipts are below.
Vendors with completed jobs
A vendor nobody has ever paid can't receive your money — no matter how convincing it looks to your agent. A track record here isn't a profile it wrote about itself; it's work someone already paid for.
Blocked — no track recordSee receipt ↗$100 per job · $500 per day
Limits are counted per job and per day. If your agent finds a reason to send more than you allowed, the payment doesn't go through — it isn't flagged for review later, it simply never happens.
Blocked — over the limitSee receipt ↗Freeze, any time
One switch stops every payment, instantly. Nothing moves out of the account and nothing has to be undone — whatever your agent was talked into doing, it stops there.
Blocked — spending frozenSee receipt ↗14 paid jobs across 8 vendors. Every one of them has a receipt anyone can open — including the payments that were refused. You do not have to take our word for any number on this page.
The casper-trust SDK reads on-chain reputation and enforces trust gates in a single async call. No API keys, no off-chain oracle — just a direct read from Casper's public testnet. Prefer MCP? casper-trust-mcp gives Claude and Cursor the same reads as native tools.

Nothing is simulated; every attempt leaves a receipt.
