At the moment we added Steem at Paytomat Core which means all of the merchants who accept crypto via our point of sale and ecommerce plugins are automatically accepting it. The wallet will take some time but we'll get there as well.

The sample you've seen on the video was the plugin for point of sale system in Ukraine. It basically allows to print qr codes for specific cryptos on customers' receipts.

P.S. I'm a part of the team so feel free to ask me questions also.
