WIP V1 of the "Ultimate Backup Card" PDF can be downloaded here https://coldcardwallet.com/docs/recovery-cards
The goal of this card is to take down as much info as possible for future proofing. We will ship them free with some of our products soon
I will add a Glossary/Docs on how to use it soon
@nvk I've been thinking about things to backup on steel in addition to seed words. I'm uncomfortable with steel backup solutions that only include seed words. I made a list:
1. wallet passphrase
2. derivation paths
3. scripts used
4. original wallet hardware/software name
Those seem like the minimum.
Would be nice to have:
5. gap limit
6. wallet version
7. original wallet name
8. birth date of seed
Hadn't thought of a many of the things on your backup card.
