If someone finds your seed today, you lose everything.

Turn your 12/24‑word seed into a scrambled 26/52‑word sequence.
Even if someone finds that sequence, without your personal phrase they cannot access your wallet.

The real risk

Your seed phrase is the master key to your crypto wallet (Binance, Ledger and any other).
If someone finds your seed, they don’t need to hack anything — they just import it and withdraw your coins.
Paper can be photographed or destroyed, metal plates can be found, phone notes and photos can leak, cloud storage can be hacked.
If you store your seed in any online app or service, anyone with access to that account can steal your funds. LockSeed is 100% offline — your seed never touches the internet.

A different approach

LockSeed is not a wallet. It is an extra protection layer for your seed phrase.
You keep using your favorite non-custodial wallet.
The app scrambles your 12/24‑word seed into 26/52 words, based on a secret pattern only you know.
Without this pattern (and without your personal phrase), the saved sequence is useless for stealing your funds.

The result:

You can store this sequence anywhere (Google Drive, WhatsApp, paper, email). If someone finds it, they cannot recover the correct order of the words or access your wallet.

How it works

Simple, fast, and built for self-custody users.

You enter your 12 or 24‑word BIP39 seed inside the app, fully offline.
You define a personal phrase or reading pattern (never stored on any server).
The app generates a scrambled 26/52‑word sequence based on your phrase.
You save this sequence wherever you prefer.
When you need to restore, you use LockSeed plus your phrase to rebuild the correct seed order.
