Seed Phrase Splitter: 2-of-3 Recovery Backup
Split a 12 or 24-word crypto recovery phrase into three paper backups — any two restore it. We split your phrase into three cards using a 2-of-3 "interlocking" scheme. Any single card is useless to a thief, but any two matching cards combined will restore your phrase.
💡 Tip: Use lowercase and single spaces between words.
How it works: We generate three unique shares (S1, S2, S3) that XOR to your original phrase. Card 1 gets (S1, S2). Card 2 gets (S2, S3). Card 3 gets (S3, S1). If you lose one card, the other two still contain all three shares needed to recover.
✍️ Write these codes down on three separate physical cards. Store them in different locations (e.g., your home, a bank vault, and a trusted family member's house).
