SEEDMATE

Offline device for BIP39 operations.

Nmemonic generation with entropy control. Use dice rolls, coin flips, random word picking or free running timer.

Custom Shamir Secret Sharing implementation:

• Each part is a valid BIP39 nmemonic

• Split into m parts (m≤9)

• Merge using k parts (2≤ k ≤6)

XOR operator:

• Combine entropies

• Split/merge schemes

Obfuscation methods, make reversible operations to create another valid nmemonic:

• Entropy circular shift at bit level. Left/rigth n bits

• NOT operator. Negate entropy bits

• ADD /SUB. Each word is incremented/decremented n units

SD card export/import (included)

QR seed export standard/compact, compatible with Krux, seedmate & other devices.

SeedMate works with all BIP39 wallets.

Power source: AAA batteries (included). Runtime: 15+ hours.
