Interesting, can we have tiers like Patreon?
Take a look at XMRchat (https://xmrchat.com/).
It is a platform like Patreon (https://www.patreon.com/) except paymenta to content creators and streamers are P2P and with Monero.
Discussion
Due to the peer-to-peer non-custodial nature of the payments, the platform cannot sign transactions on senders' behalf. Each sender must actively sign each transaction they want to send. So it is not possible to set up a subscription plan with automatic regular payments.
They can, however, choose the amount they want to donate freely for each payment.
