So there is a company called Wala, which is building out the on the ground infrastructure that Manna and other UBI enthusiasts have been clamoring for.

"And with 100,000 merchants offering goods and services through Wala's platform, the startup has created a small-scale circular economy – something crypto enthusiasts have long vied for.
"They can buy airtime, data, pay their electricity bills or their kids' school fees," Martinez said, adding:
"Not only can they do it in their country, but they can do it across 10 markets. So if you are in South Africa and your mom lives in Zimbabwe, you can buy her airtime or pay for her electricity.""
This is a huge deal. It means that to make Manna useful on a practical, day to day level as a UBI in Africa, all we would have to do is provide a way to exchange Manna for Dala (Wala's cryptocurrency). That's a lot less work than trying to set it all up ourselves. The future is near!
