The first wallet: Tamga Wallet

The best way to show that a network works is a wallet that actually uses it. Tamga Wallet is this network’s first wallet: an EU-compatible app built so that people can carry their credentials on their phones and show only the information that is needed.

A participant, not part of the network

Tamga Wallet is a separate product with its own team, its own decisions and its own site. It joins the network like any other wallet: it shows that it follows the wallet rules and is listed as a wallet provider. The network gives it no privilege; every wallet that follows the rules has the same rights on the network.

What does it do?

• Receive credentials from institutions, by scanning a QR code or finding the institution in the app.
• Keep credentials on the phone: they sit on the device, not on a server.
• Show only what is needed: see which information will be shared and approve it.
• Sign in to websites with “Sign in with Tamga”, with a different pseudonym for each site.
• See what was shown to whom: the record is kept only on the person’s phone.

Why an example wallet?

Rules can be right on paper, but they have to work on a real phone with a real user. Tamga Wallet shows that these rules can be implemented and serves as an example for others who want to build a wallet. Any team that wants to become a wallet provider can use the same open packages and the same conformance tests.
