Here's a wallet from KG of Machankura USSD wallet.

Imagine a family, village clan, savings group, or community organisation having its own shared Bitcoin wallet, managed collaboratively by its members.

Think of it as a federation-like model.

Instead of trusting one person to control the group's funds, members collectively participate in managing the wallet. Someone proposes a transaction, and other members approve it before the funds can be spent. Spending becomes a collective decision rather than an individual's privilege.

This could work particularly well in African communities, where families, clans, churches, and village groups already have established structures for collective decision-making.

Imagine a clan treasury where members contribute sats, save together, support one another, and fund community projects. No single member has absolute control. The rules are agreed upon, and spending follows the group's approval process.

Think of it as bringing the principles of federations into everyday community self-custody.

Federations such as those built around Fedimint demonstrate how people can collectively hold and manage Bitcoin without relying entirely on a single custodian.

Machankura definitely makes this concept more accessible, especially to people using feature phones without smartphones or internet access.

The exciting possibility is that self-custody doesn't always have to be an individual experience. It can also be collaborative.

From individual sovereignty to collective sovereignty. From personal wallets to community treasuries.
