Blockschmiede Wallet

Blockschmiede Legacy 21 combines three core areas in one modern Bitcoin app: NFC cards, digital gift cards, and a full-featured Bitcoin & Lightning wallet.

Use physical NFC Bitcoin cards, create digital Bitcoin gift cards, or securely manage your own smartphone wallet directly inside the app — all in one single solution.

The 3 Core Areas

NFC – Use Physical Bitcoin Cards

Scan existing NFC cards or set up new cards directly in the app.
