Shamir Safe: Protect Your Crypto with Secret Sharing

Secure your cryptocurrency wallets using Shamir's Secret Sharing (SSS) — the same cryptographic standard used by banks and security professionals. Split your seed phrase, private keys, or any sensitive data into multiple encrypted shares. No single share reveals your secret.

HOW IT WORKS: Shamir's Secret Sharing splits your secret into N shares, requiring only K shares to reconstruct it (K-of-N threshold).

Example: • Split seed into 5 shares • Require 3 shares to recover • Distribute shares to trusted locations • Lose 2 shares? Still recover your secret!

KEY FEATURES: Secret Sharing (SSS) • Split seed phrases, private keys, passwords • Custom threshold (K-of-N) • Supports BIP39 mnemonics • Any text up to 2000 characters

Secure Storage • No internet required (offline-first)

Share Management • Create unlimited shares • Label shares for organization

Recovery Tools • Visual share counter • Threshold indicator • Step-by-step reconstruction • Validation before saving

Privacy First • Zero data collection • No analytics, no tracking • Open-source cryptography • Works completely offline

PERFECT FOR: • Crypto investors securing seed phrases • Multi-sig wallet backup strategies • Estate planning for digital assets • Teams sharing sensitive credentials • Anyone needing secure secret distribution

USE CASES:

1. Personal Backup:

   • Create 3 shares, require 2
   • Store: phone, laptop, safety deposit box
   • Lose one device? Still recover!

2. Family Inheritance:

   • Create 5 shares for family members
