FREE SHIPPING WORLDWIDE
Air-gaped BIP39 calculator.
Mnemonic generation with real world randomness, avoid weak entropy risk. Use dice rolls, coin flips, random word picking, poker cards or free running timer (recommended for test only).
All operations are Ian Coleman BIP39 tool equivalent.
XOR operator:
Mix different entropy sources.
Split/merge schemes
Custom Shamir Secret Sharing implementation:
Each part is a valid BIP39 mnemonic
Split into m parts (m≤9)
Merge using k parts (2≤ k ≤6)
Obfuscation methods, make reversible operations to create another valid mnemonic:
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 (SD included)
QR seed export standard/compact, compatible with Krux, Seedsigner & other devices.
SeedMate works with all BIP39 wallets.
Open source firmware.
Power source: AAA batteries (included). Runtime: 15+ hours.
Available colors: orange, black, white, green and blue.
