1) "half" is six words you memorize
2) "other half" is a long annoying non-memorizable string that must be written down?
Am I missing something?
Border Wallets offers a new way of storing, memorising and transporting Bitcoin seed phrases for people who:
- have difficulty/concerns with securely caching physical seed backups (evil maid attack)
- want to memorise their seed words but struggle to do so (e.g. the 15% of the global population who are dyslexic)
- want to carry their seed words with them at all times
- have limited access to trusted 3rd parties
- live in areas of conflict, war zones, etc.
- regularly travel or move around
- have no permanent fixed abode.

I once generated a Bitcoin private key with a SHA-256 hash of a pop song lyric. Within 3-days the roughly $100 I sent to that wallet, as a test, was drained.
Entropy matters.
Secure grid generation is provided by the Entropy Grid Generator tool, and the wallet(s) users create with it can be used in conjunction with existing backup methods if desired for when this solution needs to be invoked. We cover various use cases on our website, which also includes a full video demo which is easy to follow.
As for grid storage, there are several options for that:
1. Physical print
2. Digital storage
3. Encrypted digital storage (native encryption is a feature within the tool)
4. Recovery phrase for deterministic grids using 12 words - which provides an additional layer of security against evil maid (or border guard) attacks, as well as the option for decoys
5. Gridception (explained on our website)
However, I want to mention the technique of making up a story to remember the seed words. I found this to be fairly easy so I am not sure how this grid can be more useful than that.
But still a very cool and interesting idea! Thanks for sharing. (You even made me create a HN account to post my first comment)
