Is your recovery phrase truly protected?

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

The real risk

Your seed phrase is the recovery key for your wallet, used by major wallets and devices.
If someone finds your seed, they can use it to restore access to your wallet.
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 may expose your recovery data. 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 cannot be used to reconstruct your recovery phrase.

The result:

You can keep the generated sequence in the place that best fits your personal routine. If someone finds it, they cannot recover the correct order of the words or interpret your recovery data.

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.
