A popular feature in other social media is tip crypto like Nostr using Lighting and Farcaster using Ethereum tokens.
There is no social media using tipping as piconeros, looking for opinions and discussion if this could be done in Monero.town?.
The idea could be revisited when Jamtis got implemented. Then you could just give away the key for generating new addresses (for every comment).
But I’d prefer a field in the profile for donation links. Then you could probably check for if it is a link to a site or a crypto address and then show a ‘Send tip button’. If one doesn’t want a custodial wallet you just open the address in an external wallet.
