Usually with projects like this in crypto grants are paid up front to cover full development over many years. That being said, no revenue has been generated so far as we have only 2 weeks ago reached a point where we could launch this tech live. There is still some way to go to be selfsustainable.
The claims in the post about Magi being the pinnacle of crosschain tech development and 1 of only 4 protocols that exist out of tens of thousands that reached this level is not an exaggeration, it is a fact. This kind of tech takes a lot of time and expertise to develop.
If it was easy everyone would have built this already and saved billions in funds stolen by hacks. But they didnt build it, thats how big of an endeavor it is, when top chains find it more financially viable to lose billions over attempting to build a Magi type protocol.
