Open-source, air-gapped way to etch Bitcoin seed & descriptor backups into steel
 | I wanted a way to create durable multisig backups without relying on specialized engraving hardware. SeedEtcher is an open-source, air-gapped workflow that prints seed phrases, descriptors, and QR codes with a standard laser printer and permanently etches them into metal. It’s fully reproducible, uses boring, well-understood tech, and is meant to complement existing metal backup solutions and make it more accessible. [link] [comments] |
