Border Wallets is built using BIP39, and is designed to make memorising and transporting seed phrases across borders more secure and much easier for people.

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)
