https://techcrunch.com/2021/04/06/signal-tests-payments-in-the-uk-using-mobilecoin/ > Encrypted chat app Signal is adding payments to the services it provides, a long-expected move and one the company is taking its time on. A U.K.-only beta program will allow users to trade the cryptocurrency MobileCoin quickly, easily, and most importantly, privately. > If you’re in the U.K., or have some way to appear to be, you’ll notice a new Signal Payments feature in the app when you update. All you need to do to use it is link a MobileCoin wallet after you buy some on the cryptocurrency exchange FTX, the only one that lists it right now.
