Vault12 primary sources — 2026-05-06

Project status in this pass

  • Vault12 does have first-party technical whitepaper material.
  • The official GitHub whitepapers repository links to a Vault12 cryptostorage technical whitepaper and a separate NaCl-based Zax relay specification; both PDFs were saved locally in this repository.
  • The clearest current operational sources of truth were the homepage, inheritance/product pages, help-center setup and recovery guides, and the GitHub organization.

Saved primary documents

  • vault12-technical-whitepaper.pdf — downloaded from Vault12’s own whitepapers repository link (http://bit.ly/vault12-whitepaper as referenced on https://github.com/vault12/whitepapers)
  • vault12-zax-relay-spec.pdf — downloaded from Vault12’s own whitepapers repository link (http://bit.ly/nacl_relay_spec as referenced on https://github.com/vault12/whitepapers)

Primary-source snapshots

1) Homepage positioning and custody disclaimer

  • URL: https://vault12.com/
  • Key excerpt:
    • The homepage says Vault12 is not a financial institution, exchange, or custodian and does not hold, transfer, manage, or access user funds.
    • It instead describes itself as a non-custodial information-security and backup tool for storing wallet seed phrases and private keys for inheritance.
    • This disclaimer is central to the classification because it rules out several misleading categories at once.

2) Digital inheritance product page

  • URL: https://vault12.com/product/inheritance/
  • Key excerpt:
    • The product page says owners can assign a legacy contact, typically an executor, trustee, or beneficiary, who can gain access to the portfolio of seed phrases and private keys in the owner’s Digital Vault.
    • It also says Vault12 uses a decentralized approach rather than dependence on USB devices, hardware wallets, or cloud servers alone.
    • This page makes clear that inheritance is a first-class feature, not a side note.

3) Help-center overview and company FAQ

  • URL: https://vault12.com/help/
  • Key excerpt:
    • The help overview says Vault12 secures crypto assets by encrypting, splitting, and distributing them on a mesh of mobile devices in a trusted personal network.
    • It also says the system is designed so assets in the Vault do not reside only on the owner’s mobile device and can be restored if the phone is lost, damaged, or stolen.
    • The same help corpus says the ZAX Relay Network is open source on GitHub.

4) Vault setup guide and guardian model

  • URL: https://vault12.com/help/digital-vault-setup/
  • Key excerpt:
    • The setup guide says users can create a Vault, add Guardians, and set up inheritance from the main product flow.
    • It recommends 3 Guardians total with confirmations from 2 out of 3 Guardians to recover the Vault.
    • The guide explicitly suggests a mix of trusted people and spare personal devices, which reveals the social-recovery-plus-device-redundancy trust model.

5) Asset unlock and privacy behavior

  • URL: https://vault12.com/help/recovery-phrase-vault12/
  • Key excerpt:
    • The unlock guide says Guardians are asked to confirm the owner’s request but do not see which specific asset is being accessed.
    • It also says the owner is expected to contact Guardians directly so they can validate that the request is genuine and that the owner is in a safe position to access valuable digital assets.
    • This is a strong indicator that Vault12 is mixing cryptographic controls with social verification rather than relying on pure wallet UX alone.

6) Restore flow and broader platform scope

  • URL: https://vault12.com/help/restore-digital-vault12/
  • Key excerpt:
    • The restore flow confirms that Vault recovery can be initiated after device loss and coordinated through Guardian responses.
    • The broader setup guide also shows the product is not limited to crypto seed phrases: it can protect NFTs, 2FA codes, passwords, IDs, medical records, and other sensitive documents.
    • That wider scope matters because Vault12 is crypto-centered but clearly sits at the edge of the crypto stack as survivability and secret-management infrastructure.

7) GitHub organization and whitepapers repository

  • URLs:
  • Key excerpt:
    • The GitHub org exposes pinned repositories for the Zax relay, client libraries, recovery utilities, and whitepapers.
    • The whitepapers repository says the Vault12 cryptostorage platform is based on hierarchical Shamir’s secret sharing and links to a separate NaCl-based relay specification.
    • The public code and docs surface strengthens the case that Vault12 is infrastructure and operating-model software, not merely a consumer inheritance landing page.

Working conclusion

Vault12 is best cataloged as non-custodial inheritance and key-survivability infrastructure / guardian-based secret-backup control plane / crypto recovery and social-recovery tooling. The deciding evidence in this pass was the combination of explicit non-custodial disclaimers, a concrete guardian threshold-recovery model, beneficiary/inheritance workflows, and first-party technical material covering both the broader cryptostorage platform and the Zax relay substrate.
