Why not integrate Monero in the fediverse? That seems more useful.

The way I see it, for small transactions, I could deposit some Monero (say $20 worth) on chain to lemmy.world. Then I could use $10 to sponsor lemmy.world (or even pay a monthly subscription through it) and I could also instantly send $5 for coffee to a coffee shop that has a Mastodon account through the fediverse. The recipients can collect these small amounts and retrieve them in bigger batches on chain.

As long as the amounts are small, security and privacy considerations aren't that big. And the convenience of easy addressing and instant transfers would be a huge boon.

And in the fediverse I can always create a new account with any other server when I feel like it, so some privacy is easily achievable.

For bigger amounts or privacy sensitive amounts, on chain is the way to go anyway.
