Hey everyone! I wanted to share a project I’ve been working on: the Polyseed Secret Sharing Tool. It’s a Python CLI application that uses Shamir’s Secret Sharing Scheme to back up a Monero polyseed. This method dramatically increases security by breaking your seedphrase into multiple shares, where a predefined number of shares are needed to reconstruct the secret. It’s an innovative approach to avoid the risk of having your entire wallet compromised if one location is breached.
This tool is currently in the experimental stage and I would love to get feedback and contributions, especially from those skilled in cryptography and coding. It’s designed for use in a secure, air-gapped environment (like TAILS) for maximum safety.
Check it out, and let’s discuss how we can make the Monero experience more secure!

Keep in mind that I created this today and it still needs a lot of testing and cleaning
Right. I believe paperback can store about 1 kilobyte in each QR code. Up to six QR codes per page. So it’s about 6 kB of data. Which is more than enough for your 25 seed words.
It might be interesting to use this as an amalgam for the printed format, for the offline version.
