Interesting information, researching the work of e-wallets, I started when I got acquainted with cryptocurrency and I had a need to quickly transfer fiat money to the crypt and back. However, over time, I realized that the e-wallet is not just for transactions. Its main value is the ability to provide fast payments on the Internet with both financial and non-financial funds. The development of such wallets is a rather cumbersome task. However, today hundreds of companies like this chisw.com are developing e-wallets. And I'm sure that payments through e-wallets are the future that awaits us soon enough.
