Enabling this feature will prevent customers from performing cash-in transactions using the same address more than once.
If the same address is scanned again after it's already been used, the machine will prevent that transaction until the user generates a new address.
Some reasons you may want to prevent address re-use:
- Reduces the impact of scams which employ a static address
- Increases privacy for the user and operator by encouraging fresh addresses
- Compliance with particular regulations in your jurisdiction
This feature is available in Defiant Dingirma v7.4. To use it, please first upgrade to the latest release.
Enabling Reject Address Reuse
To enable, visit the 'Global Settings > Compliance' panel of your admin and set 'Reject Address Reuse' to 'On'.
Going forwarded, newly scanned addresses will be added to an address blacklist. If a user attempts to scan an address from that list, they will be prompted to generate a new one with the screen shown at the top of this article.
Note: You may also blacklist individual addresses manually.
