Reject Address Reuse

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 and higher. To use it, please first upgrade to the latest release.

⚠️ ‏‏‎ ‎NOTE: This feature enables for all cryptos except ETH, as the vast majority of ETH wallets re-use a singular address, rather than generating new change addresses. (Thus, if applied to this coin, a user would have to create a new wallet for every ETH transaction.)
 

Enabling Reject Address Reuse

To enable, visit the 'Compliance > Triggers' panel of your admin and set 'Reject reused addresses' 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.
