Important Security Notes

  • Never enable withdrawal permissions — Crypto Broker only needs trading access.
  • Restrict your API key to your IP address whenever possible for additional security.
  • Your API keys are stored locally on your device using OS-level encryption — they are never sent to our servers.
  • If you suspect your API key has been compromised, delete it immediately on the exchange.
