What is Nostr?
Africa is where Bitcoin is needed the most. There are however limitations of smartphone possession and internet access. These conditions make technologies like SMS and USSD a popular use case across the continent. Many Africans use USSD and SMS portal services to access financial services and purchase goods and services.

This is where Machankura becomes a solution.What is Machankura? Machankura is a Bitcoin Wallet that lets users access Bitcoin and gain Financial Freedom on any mobile phone without internet. A user will manage the wallet through their USSD menu. While there's a maximum fee of approximately 1% to send a transaction, Machankura is free to use.

To get started, dial:
Ghana: *920*8333#
Kenya: *483*8333#
Malawi: *384*8333*1234#
Namibia: *142*8333#
Nigeria: *347*8333#
South Africa: *134*382*382#
Tanzania: *149*46*26#
Uganda: *284*8333#
Zambia: *384*8333#

Upon dialing the number for the first time, you’ll need to set up the account tied to your phone number and create a 5 digit PIN you will use to confirm transactions. After registering, a subsequent menu offers additional functionality like sending or receiving bitcoin and viewing balance and transaction history (users press the number corresponding to the desired menu option).

Machankura’s default Lightning address combines a user’s phone number and Machankura’s “@8333.mobi” domain (e.g., 123456789@8333.mobi). Users can also modify these addresses to conceal their phone numbers (e.g., username@8333.mobi). You now can receive funds using your Lightning address, or Onchain address, or redeem Azteco voucher.

Once you’ve set up your wallet account, you can send and receive money in Bitcoins, Satoshis, Dollars or Kwacha to either other Machankura users via their username or phone number. You can also send to both Onchain and Lightning address of anyone, anywhere, at anytime without any need for internet connection.

Machankura also let's users pay a Lightning invoice. For example: https://8333.mobi/malawi
