Thank you for the suggestion.
The plugin is not directly compatible with staking rewards from PoS wallets. This is because there is no 1-1 correlation between user balances and anything in the hot wallet itself.
You can use the Airdrop extension to define a recurring airdrop. A recurring airdrop is one that is executed at regular intervals (such as every day/week/etc). The airdrop amount can be a fixed amount or a percentage of a user balance, and you can specify the airdrop to apply to all users or to a specific user role only.
Hope this helps. Please let me know if you have any more questions about this.
