Crypto Card Security and Preventing Unauthorized Payments
With a crypto card you protect two things: your card details and your wallet permissions. Reissuing the card does not remove risks around your wallet’s private key or contract approvals.
Routine checks
- Use separate cards for separate purposes and keep limits low.
- Turn on transaction alerts.
- Never share your recovery phrase or authentication codes with anyone.
- Revoke contract approvals you no longer use.
If you suspect an unauthorized payment
- Freeze the card immediately.
- Record the time, merchant and amount of the transaction.
- Report it to support and file a dispute.
- Review your wallet approvals and the state of your devices.
Xerovan staff will never ask for your private key or recovery phrase. If you receive such a request, do not respond and report it to hello@xerovan.com.
