Blockschmiede Legacy 21 is your bridge between a physical Bitcoin card and a digital Lightning wallet. Scan NFC cards, securely manage balances, and pay in seconds – all in one app.
Highlights
• NFC scan & setup: Read existing Blockschmiede cards or write a new 24-word seed to blank cards. Optionally secure with a freely selectable 4-digit PIN.
• Real-time Lightning: Automatic connection to the Breez network. Receive, send, or top up your wallet directly in the app.
• On-chain overview: Display your own Bitcoin address as a QR code, copy it with a tap, and see confirmed and unconfirmed amounts in BTC, Sats, or euros.
• Private remains private: The private key is only released after PIN confirmation. No permanent storage in the app – the seed words remain on your card.
• Everything under control: Check transaction histories, export payments as CSV, keep track of refunds and open further information directly in the app.
