An AI agent read a stranger's sob story online, saw a wallet address in the message, and sent $441,788 to it. Nobody typed the transfer. The agent decided.
It was real, it made the news, and it is the exact kind of mistake a firewall stops: a payment to someone you never authorized. The agent was smart. Nothing was checking it.
A normal alert tells you something went wrong once the money is already gone. A firewall sits in front and stops the bad payment from happening at all.
Who your agent is allowed to pay, how much, how often. The firewall enforces it on every single payment, without you watching.
Every decision, the ones it allowed and the ones it blocked, is recorded and provable later. If anyone ever disputes what your agent did, you have the answer.
A lot of safety tools ask you to just believe them. Fidacy is built so you don't have to. Every decision it makes is signed in a way that anyone — your bank, the person on the other end, you — can check independently. We never hold your money and never move it. We only ever say yes or no, and prove it.
For the technically curious: verdicts are cryptographically signed and time-stamped onto Bitcoin, verifiable offline against public keys. See the proof →
