I can answer for UPI.
Unlike AliPay/WeeChat, the central agency (NCPI) only maintains the API. Businesses are free to develop apps on top. In India, there are 50s of apps enabling UPI transactions. You are free to download whatever app you prefer unlike AliPay/WeeChat duopoly.

I tried doing this 2 days ago for AWS lambda arm64 runners.
And it did not work. Has anyone successfully built a statically linked golang binary arm64 runners in Lambda?
