Can't provide a total accurate for rotki as it's a project running since 2017.

I can say we got ~10k USD in last gitcoin round, ~11 ETH in Octant and currently streaming ~150k OP for RPGF round 3.

And as all other user facing apps we are no longer eligible for RPGF so there won't be any more of that. Which is why gitcoin is all the more important for us this round.

We also get income montly from our premium users. This amounts to ~2-4k EUR per month.
