Offline Raspberry Pi 4 Crypto Wallet
Budget: $30 – $250 USD
I want a bootable .img image for the Raspberry Pi 4 that turns the board into a fully offline, hardware-style wallet. After flashing the image to an SD card and powering up, I expect a clean graphical interface that lets me:
• Generate and manage addresses for roughly forty of the most-used coins and tokens.
• Sign and later broadcast transactions only when I briefly connect the Pi to a network.
• Move funds straight to a linked bank account by entering a routing and account number—ACH style—without ever needing a third-party exchange.
The build has to run reliably with no internet dependency at first boot, keeping all keys on the device and encrypted at rest. A simple on-screen flow for first-time setup, balance overview, and transfers is essential; I should never need to drop to the command line.
Deliverables I need from you
1. A tested .img file that I can flash with Etcher and boot immediately.
2. Source code or build scripts so I can reproduce the image.
3. A brief PDF or markdown guide covering initial setup, backup procedure, and how to trigger a bank transfer.
I’m flexible on the underlying OS and tech stack as long as the GUI is smooth and the final package is self-contained. If you already have experience with multi-coin libraries (e.g., Electrum, BTCPay, or similar) and can integrate a banking API or ACH library, that will give you a head start. Security features such as 2FA, biometrics, or additional encryption layers can be proposed, but the core requirement is an offline-first, plug-and-play wallet image with direct bank payout capability.
