Crypto Vurny vs WujiSeed

Crypto Vurny is the first and only iOS app that lets you fully customize your BIP39-compliant mnemonic seed phrase — putting control and memorability in your hands. Traditional wallets generate random phrases for you. Crypto Vurny lets you choose your own words, then calculates a valid checksum to complete the phrase, ensuring full compatibility with any wallet that supports BIP39, including Bitcoin, Ethereum, and hundreds of others. Key Features: Customize your own mnemonic seed phrase Automatically calculate the checksum word Supports 12, 15, 18, 21, and 24-word phrase options Fully offline and private — nothing is stored or tracked Compatible with all BIP39-based crypto wallets Why Use Crypto Vurny? Improved memorability of your crypto keys No need to rely on confusing, randomly generated phrases No need to worry about future computers making random phrase generation predictable and risking your data — Crypto Vurny puts full control in your hands. Secure by design — the app never touches your data or connects to the internet About BIP39: BIP39 (Bitcoin Improvement Proposal 39) is a widely adopted standard that defines how mnemonic phrases represent private keys. Crypto Vurny follows this standard exactly, generating valid phrases with entropy levels ranging from 128 to 256 bits. Your Privacy is Guaranteed Crypto Vurny never collects, stores, or transmits any user data. Phrase generation occurs 100% locally on your device. Security Note: Your seed phrase gives full access to your wallet. Never share it and always store it securely. Crypto Vurny does not store or recover phrases — you are in full control. Patent Notice: This customizable BIP39 method and idea is the subject of a pending Canadian/US patent. Unauthorized use may violate intellectual property law. Questions?

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
