Vaultie

Vaultie is a digital identity and document verification platform launched in 2019 that focuses on creating legally binding digital signatures anchored to blockchain technology. The platform implements a custom did:vaultie method that utilizes Ethereum blockchain for anchoring signatures and IPFS (InterPlanetary File System) for decentralized document storage. The technical architecture combines W3C DID standards with biometric verification to create verifiable credentials that link real identities to digital signatures.

At its core, Vaultie uses a hybrid approach where document hashes are stored on the Ethereum blockchain while the actual DID Documents are stored on IPFS, making the solution more cost-effective than pure on-chain storage. The platform implements several key technical features including:

• End-to-end encryption for documents both in transit and at rest
• Biometric verification through selfie checks for continuous KYC
• Integration with standard digital wallets for credential storage
• Merkle proof verification following W3C standards
• Reusable credentials that can be verified across different services

The platform has found particular adoption in the Canadian financial sector, where it is used to prevent mortgage fraud and verify high-value transactions. As a member of the Pan-Canadian Trust Framework, Vaultie works to establish industry-wide standards for digital trust and verification while maintaining interoperability with other identity solutions. The company emphasizes user sovereignty by allowing individuals to control their personal information and selectively share verified credentials with chosen parties.
