WUJI Seed turns human memory into high-entropy BIP39 seed phrases — something previously thought impossible. THE PROBLEM WITH MEMORY-BASED SECRETS Human-chosen passwords are notoriously weak. Birthdays, names, and common phrases have extremely low entropy. That's why crypto relies on random generators — but random means forgettable, and forgettable means backups that can be lost or stolen. HOW WUJI SEED ACHIEVES HIGH ENTROPY WUJI Seed uses F9Grid, a geographic grid system that divides Earth into billions of precise cells. When you input a coordinate, it maps to a specific cell index with sub-meter precision. The key insight: when you choose 5 personally meaningful locations that span great distances and are known only to you, the combinatorial space becomes enormous. Consider: • Your grandmother's house in a small village • A hidden beach from a childhood trip • The exact bench where you had your first kiss • A remote hiking spot you never told anyone about • The corner table at a café in a foreign city These 5 locations, scattered across the globe and unknown to others, create entropy comparable to random number generators — yet they're burned into your memory forever. HOW IT WORKS 1. Enter your personal identifier 2. Input 5 geographic coordinates (the more spread out and private, the better) 3. Add memory tags for each location 4. Generate your 24-word BIP39 mnemonic Same inputs, same seed phrase — recoverable from memory alone. MAXIMIZING YOUR ENTROPY For strongest security: Choose locations spanning different cities, countries, or continents Pick precise spots, not general areas (the specific tree, not "the park") Select places only you would know or remember Avoid famous landmarks or locations shared on social media The wider your geographic spread + the more private your locations = the higher your entropy. KEY FEATURES Geographic Entropy F9Grid extracts maximum randomness from your location choices. Wide-spread, private locations yield security rivaling hardware random generators. 100% Offline All operations local. No internet. No data leaves your device. No Backup Required Your brain is the backup. Remember 5 locations, regenerate anywhere. Deterministic Same inputs always produce the same result. Test it yourself. Bank-Grade Cryptography Argon2id key derivation, BLAKE2b-256 hashing, XChaCha20-Poly1305 encryption. BIP39 Compatible Works with Ledger, Trezor, MetaMask, Trust Wallet, and all standard wallets. Privacy First No accounts. No cloud. No tracking. WUJI Seed — For the Memories That Never Fade
