How It Works

Your Mobinumber is cryptographically derived from your seed phrase. It's deterministic—the same seed always produces the same Mobinumber.

• Unique to your wallet
• Easy to remember and share
• Cannot be changed or transferred

Use Cases

• Identity — Share your Mobinumber instead of a long npub
• Payments — Receive Bitcoin using your Mobinumber
• Authentication — Log in to services with your identity

Privacy Note

Your Mobinumber is public. Anyone can look up your public key from it. Only share it with people you want to be able to contact you.
