SecretShield provides a decentralized, client‑side encrypted vault that splits recovery phrases and passwords into cryptographic shares distributed to trusted guardians. Recovery requires a configurable threshold of guardian approvals, enabling offline reconstruction without any plaintext ever residing on SecretShield’s servers.

Problem
Individuals and businesses struggle to securely store recovery phrases, master passwords, and other critical credentials without relying on centralized vaults that are vulnerable to loss, theft, or single points of failure.
Solution
SecretShield offers a decentralized social‑recovery vault that encrypts sensitive data locally and splits it into cryptographic shares. Users designate trusted contacts as guardians; each receives a share that reveals no information about the secret. Recovery is possible only when a configurable threshold of guardians approve, enabling offline reconstruction without any data ever residing on SecretShield’s servers. The system supports flexible share distribution, optional local storage tied to hardware security modules, and a mobile app for easy management, providing a digital safety deposit box that remains under the user’s control.
Target Audience
Primary users are crypto wallet owners, individuals with high‑value digital assets, and businesses needing break‑glass access to critical accounts or estate‑planning solutions.
