Скачать или смотреть Your Ledger Can’t Do This: Custom Air-Gapped Wallet with Pi Zero & QR Signing

In this video, I demo my custom-built *air-gapped hardware wallet* powered by a *Raspberry Pi Zero* and a **secure element **.
The same codebase runs on both *desktop* and **physical device**, which makes development fast and real-world use ultra-secure.

🔐 What this wallet can do:
Fully *air-gapped transaction signing* (no direct internet on the device)
*Multi-coin support* (EVM chains + UTXO-style coins – ETH / XDC / BTC / XRP, etc.)
*QR-based send/receive* – scan transaction data in, show signed TX/addresses as QR
*PIN protection* and *wallet delete* with confirmation
Same logic running on *desktop simulator + hardware wallet device*

🧠 Tech stack & architecture:
Raspberry Pi Zero as the main hardware platform
Python-based UI (TFT display / HDMI via Pygame)
Secure signing with ATECC608A secure element
Hardware abstraction layer for display, keypad, QR scanner
Shared core for seed handling, wallet generation, and transaction building



If you’re into **embedded systems, crypto, or hardware wallets**, consider subscribing – I’ll be sharing more deep dives on:
Secure element integration
QR-based transaction flow
Multi-wallet & multi-network support

Drop them in the comments – I’m happy to discuss architecture, code structure, and security assumptions.
