Hello,
Thank you for the clarification.
It is definitely possible to bind to the wallets_transaction action, observe the incoming data, and if the transaction is a stake reward, send an email using wp_mail. You can implement this easily in your functions.php file or a small separate plugin. Take care, because different wallets implement rewards differently: Some wallets remove all your balance, then add your balance again, plus the reward. In other wallets, the reward amount is added separately in a new transaction. So look at your wallet’s listtransaction output first.
I am not planning to add a feature where POS rewards are added to the admin account. Part of the reason is that due to incompatibilities between POS wallets, this will cause problems.
with regards
