Vault12 Releases Open-Source Capacitor Plugin for Quantum-Safe Data Storage

Production-proven Shamir’s Secret Sharing now available for iOS, Android, and Web apps


Miami, FL – December 2, 2025 – Vault12, Inc., the pioneer of crypto inheritance, today announced the open-source release of the Shamir Secret Sharing plugin for Capacitor, a new plugin for the Capacitor framework that enables app developers to add quantum-safe data storage for iOS, Android, and web applications using Shamir’s Secret Sharing.

The Shamir Secret Sharing plugin for Capacitor plugin brings information-theoretic security—protection based on mathematical impossibility rather than computational difficulty—directly into modern, cross-platform app stacks. By splitting sensitive data into multiple cryptographic shards, developers can eliminate single points of failure and build applications that remain secure even in a post-quantum world.

This plugin has already been battle-tested in production for a decade on almost a million iOS and Android devices, as a core component of Vault12 Guard, a mobile app that provides decentralized backup, and inheritance for crypto wallets and other sensitive data.

“Developers building self-custody and high-assurance apps need tools that won’t break the moment quantum computing becomes practical. With the Shamir Secret Sharing plugin for Capacitor, we’re making the same Shamir’s Secret Sharing engine that powers Vault12 Guard available to anyone building the next generation of secure, user-controlled applications.”

— Blake Commagere, Co-founder and COO, Vault12

Shamir’s Secret Sharing (SSS), originally devised by Adi Shamir (the “S” in RSA), allows a secret to be mathematically split into multiple shares, with a configurable threshold required to reconstruct it. Individual shares reveal nothing about the underlying secret, ensuring that no single compromise exposes user data.

Capacitor is an open-source, cross-platform native runtime that lets developers build iOS, Android, and web apps from a single modern JavaScript/TypeScript codebase. It provides a consistent API and plugin system to bridge web frameworks (React, Vue, Angular, etc.) with native device capabilities such as secure storage, biometrics, and the filesystem.

Key features of the Shamir Secret Sharing plugin for Capacitor plugin include:

  • Quantum-resistant security using Shamir’s Secret Sharing with information-theoretic guarantees
  • Cross-platform support for iOS, Android, and Web via Capacitor
  • Flexible storage options, including memory-based and filesystem-based operations
  • Progress tracking for long-running operations and large files
  • Robust recovery, supporting reconstruction of complete secrets or individual shards
  • Production-proven reliability, already protecting high-value digital assets for Vault12 Guard users

You will lose your Bitcoin and other crypto when you die...

...unless you set up Crypto Inheritance today.

It's simple — if you don't worry about crypto inheritance, nobody else will — not your software or hardware wallet vendors, not your exchanges, and not your wealth managers. So it's up to you to think about how to protect the generational wealth you have created, and reduce the risks around passing that crypto wealth on to your family and heirs. What are the challenges with crypto inheritance?

  • Crypto Wallets are difficult to use and do not offer crypto inheritance management. In fact, most of them tell you to write down your seed phrase on a piece of paper, which is practically useless.
  • Some people back up their wallet seed phrases or private keys on paper, local devices like hardware wallets or USBs, or in the cloud. All of these options have severe drawbacks that range from hacking to accidental loss to disrupted cloud services.
  • Software wallets operate on specific blockchains, yet your crypto assets span multiple blockchains. For inheritance to work, you must be able to manage inheritance across every blockchain — now and forever.
