How wallet developers get rich: 1/ Find a few coders and wallet source code, add attractive functions and UI, and manage all the development process in a standardized way 2/ Upload a part of the "core" source code to github and promote it as open source 3/ After the upgrade code is summarized, add a random letter somewhere (one-way encryption), compile and package it and submit it to Apple for review (AppId is only controlled by me), it will append a few bytes to a certain segment of normal transmission bytes
