I don't hink it could be current since the latest update in the Bitcoin network occured a couple of months ago and is the most important update in four years.
Some companies already enable credit card payments with Bitcoin, well before the update but afaik they are restricted to some physical regions and wallets which is a sign there are probably on and off ramp non permisionless issues. . I think that is the challenge and any improved OS solution will probably make use of Lightning L2 scaling,. There are also some new bitcoin defi protocols that could be worthwhile exploring.
Id suggest posting the question to someone like Andreas Antanopoulos.
Nice project, good luck!
