Even if you are just providing the tool/technology, you may still be subject to money transmitter license requirements ? and in the US, each state has its own money transmitter license requirements... ughhhh ? I believe people who have been looking to become a USD anchor have been facing regs as the biggest issue - as you pointed out, from tech perspective, building the anchor is quite easy but when it comes to regs in the US, it's a bit of mess and would incur quite a bit of cost... But I agree that the work is not wasted, serves as a good example, and Stripe did say that while they've ended the bitcoin related services, they are looking into supporting other tokens in future like Lumens.
