Well yeah, in DeFi you also wouldn't have an anti-fraud gateway because then there'd be no transactions.

I've developed a DeFi anti-fraud gateway, first version runs on stdin:

  yes '"Fraudulent Transaction Detected"'

I also have a json api:

  while true; do echo 'HTTP/1.1 200 OK
  Content-Type: application/json; charset=UTF-8
  Server: anti-fraud gateway
  
  "Fraudulent Transaction Detected"'|nc -l 8123;done
