Reject Address Reuse will prevent customers from performing cash-in transactions more than once using the same address. If an attempt is made to reuse an address, the machine will recommend they generate a new address for the new transaction.
There are several reasons you may want to prevent the reuse of an address:
- Increased privacy for the user and operator
- Reduce the amount sent to scam addresses
- Comply with regulations in your jurisdiction
This feature is contained in Defiant Dingirma v7.4. To use it, first upgrade to the latest release.
Enabling Reject Address Reuse
To enable, visit the 'Global Settings > Compliance' tab of your admin and set 'Reject Address Reuse' to 'On'.
Once enabled, future used addresses will be added to a reuse-blacklist, if a user attempts to scan an address from that list they will be prompted to generate a new one.
