How to create a stablecoin?

Will it be a stablecoin?

Will my words and a photo of a $100 bill be enough?

I would say no, because stable coins should be proven. A picture is just a picture. And a guarantee is just words. There should be 3rd party verification at minimum. I would also say there needs to be convertibility too. So if I have 1 stable coin and want to redeem it for a real Dollar then I should be able to do that somehow.

The only way any stable coin can be trusted is if an independent, reputable auditor reviews their holdings, practices, and and protocols annually and that a report be made available directly to the public.  This is not rocket science.  This is how many financial institutions demonstrate public trust.  When I hear that almost all stable coins are reluctant to open there books to such an audit, I immediately mistrust them.
