GLOV SSS: Mnemonic Shards

Clear and robust hardware protection for seed phrases

Back to GLOV Secure

What is GLOV SSS?

GLOV SSS is an open-source hardware solution that protects BIP-39 seed phrases with Shamir Secret Sharing.

Your seed is split into shards. A single shard is useless on its own. Only the defined threshold can reconstruct the seed in a local offline environment.

Coming Soon 100% Offline Non-Custodial

Key Benefits

  • Seed protection with Shamir Secret Sharing
  • Flexible threshold model (e.g., 3 of 5)
  • Dedicated autonomous hardware device
  • Simple local interface with no cloud dependency
  • Encrypted HTTPS local access
  • BIP-39 compatible

Core Principles

Security First

Designed to reduce real-world risk and minimize exposure.

Offline First

Local operation without cloud dependency, so you keep end-to-end control.

Non-Custodial

You remain in control of your secrets. GLOV SSS is a tool, not an intermediary.

Zero External Dependency

No third-party service required for standard operation.

Readable & Auditable

Built to be understood, tested, and audited.

Key Rule: No sensitive data (seed, shards, keys) leaves your local environment.

How It Works

1
Enter Seed Phrase

Input your BIP-39 seed phrase on the offline device.

2
Set Threshold

Choose your protection model (for example, 3 of 5).

3
Generate Shards

The seed is split into shards with Shamir's algorithm.

4
Store Securely

Distribute shards across separate trusted locations.

Reconstruction

When recovery is needed, gather the minimum shard threshold. Reconstruction happens locally for immediate use.

Frequently Asked Questions

GLOV SSS combines Shamir's mathematical robustness with a dedicated offline device. You reduce single points of failure while keeping control.

No. The interface is designed to stay simple with a guided workflow and clear instructions.

The model is built for resilience. With a 3-of-5 scheme, you can lose up to 2 shards and still recover with the remaining 3.

Yes, with BIP-39 seed phrases (12 or 24 words), covering most modern wallets.

Yes. The project is open-source and can be audited by the community and security professionals.

To protect the local session and reduce interception risk. The device enforces encrypted access.
