When saving seeds in paper form as backups, it’s also nice to have a QR code for future loading.
#modulo keys are stainless, and #seedsigner provides the QR…
…having a QR blank and a square-tipped pen makes it soooo much easier, too.

Having a blast with the #modulo key signer proof of concept. Working toward a low cost offline tool for key reading, address generation and transaction signing based on #seedsigner architecture. Thanks to
for the dev work—the man is hardcore!

Be the master of your private key.
Generate your key offline, air gapped.
Make your seed phrase manually, using #seedsigner or equivalent (even an offline spreadsheet) for your final word.
Generate your addresses, sign PSBT transactions the same way—offline.
Start strong, end strong. Keep your keys #private

I’ve been thinking of signing devices for some time since developing the modulo GENESIS key. Signing devices are the natural next step not just from a progression perspective, but from a historical signing perspective and from a private-forward future perspective.
Separation of the private key and signing device (a-la #seedsigner) is an important aspect.

The more I use #seedsigner the more I become a fan of combining its functionality with the modulo GENESIS key for offline activity.
