Have you looked at setting up Lightning Yield Wallets where we can create a wallet in order to direct the yield generated to a cause while retaining ownership of the underlying capital?
It would be like setting up a savings account that earns interest, but automatically directing that interest to wallets that belong to organizations I want to support, and the revenue would be perpetual. As long as I have a balance in the LYW, the causes I want to support get an income stream. And the more I deposit, the higher the income stream grows.
