Machankura: How Africa Is Sending Bitcoin Over SMS (No Internet Required)
Most people think you need a smartphone, an internet connection, and a shiny self-custody app to use Bitcoin.
In much of Africa, that is not the reality. Millions of people still rely on basic feature phones, unreliable data networks, and prepaid minutes. Yet Bitcoin adoption continues to rise.
The reason: Machankura, also known simply as 8333, a USSD and SMS based Bitcoin interface that works on any phone.
It is one of the most important Bitcoin projects in the world, not because it is high tech, but because it brings Bitcoin to people who live offline by default.
This is how it works, why it matters, and what it reveals about Bitcoin’s future in emerging markets.
What Machankura Actually Is
Machankura is a service that lets people send and receive Bitcoin over USSD, the same system used across Africa to buy airtime, check mobile balances, and move money through services like M-Pesa.
There is no app to install. No data required. You just dial a short code such as:
*8333#
From there you get a simple menu:
- Create a Bitcoin account
- Check your balance
- Send Bitcoin
- Receive Bitcoin
- Withdraw
- View your Lightning address
Behind the scenes, Machankura connects to the Bitcoin Lightning Network and routes payments instantly. To the user, it feels like sending a text message.
The interface works on even the cheapest Nokia style phones.
Why This Matters for Africa
Mobile money runs the African economy.
Billions of dollars move every day through simple USSD menus. People trust it because it is fast, cheap, and accessible.
Bitcoin needed a bridge into that world. Machankura built it.
It solves real limitations
- Unstable internet: Many regions experience daily outages and low bandwidth.
- Feature phones dominate: Millions still use non-smartphones.
- Data is expensive: SMS and USSD are far cheaper than mobile internet.
- Cross-border payments are hard: Banks are slow and restrictive. Lightning is instant.
It gives Bitcoin an onramp for the unbanked
Machankura users can receive Bitcoin from anywhere in the world without needing a bank account or an app store.
This is a breakthrough for remittances, micro-payments, and circular Bitcoin economies.
How It Works Under the Hood
Machankura acts as a Lightning wallet custodian that interacts through USSD. When a user sends Bitcoin:
- The user enters the recipient’s phone number or Lightning address.
- Machankura constructs and routes the Lightning payment.
- The recipient gets an SMS confirmation.
- Their Machankura balance updates instantly.
Users can also connect Machankura to external Lightning wallets via LNURL or Lightning addresses.
The system is not fully sovereign self-custody, but it offers access to Bitcoin where no other option exists. For many, it becomes a stepping stone that leads them into deeper Bitcoin education and tools like hardware wallets later.
Where It Is Used Today
Machankura works across several African countries, including:
- South Africa
- Ghana
- Kenya
- Uganda
- Nigeria
- Malawi
- Namibia
- Zambia
In each country, a different USSD shortcode is used, but 8333 has become the signature number because 8333 is the port Bitcoin nodes use to communicate.
In some regions, Bitcoin communities now use Machankura for daily transactions like:
- Paying for groceries
- Buying data and airtime
- Small business payments
- Tipping workers
- Peer to peer trading
Why This Is a Glimpse Into Bitcoin’s Future
Bitcoin will not scale through fancy apps alone. It will scale through whatever technology meets people where they are.
In Africa, that is USSD. In other places, it might be mesh networks, satellite receivers, ham radio relays, or offline QR codes. Machankura proves Bitcoin is adaptable. It bends to the environment, not the other way around.
This is also the purest form of Bitcoin adoption. People are not speculating. They are using it because it solves a real problem: moving value without banks, without permission, and without internet.

The Sovereign Perspective
For the ON Bitcoin audience, the lesson is simple.
If you want a resilient Bitcoin stack, you need options that work even when the internet does not.
Machankura is one of those options.
Not because you live in Africa, but because the world is becoming more fragile, more censored, and more connected to centralized chokepoints.
Bitcoin survives when it routes around failure. Machankura is a perfect example of that principle in action.
