Fingo, Trust Stamp deals bring biometrics, digital identity to gold sector

Gold shot up in value in 2025 as investors piled in. Now, the gold sector is becoming an unexpected proving ground for digital identity with initiatives aiming to prove the provenance of the yellow metal or securing it as a gold-backed digital asset.

After years of relying on paperwork and fragmented oversight, two separate initiatives are pressing biometric verification, cryptographic identity and material‑level authentication into the operational core of gold production and digital asset management.

SMX, FinGo and Bougainville Refinery Ltd have started evaluating a combined physical and digital authentication framework designed to verify both gold and the people handling it throughout the supply chain. The new initiative aims to test how material‑level authentication and biometric identity verification can function together in real mining, refining and export workflows.

Previously, FinGo supplied vein biometrics to boost gold mining transparency, collaborating with SMX — a company operating in the so-called circular economy — to develop a centralized reporting platform to ensure transparency within the artisanal and small-scale mining (ASM) sector.

Organizations such as the London Bullion Market Association, the World Gold Council and the DMCC have strengthened guidance around provenance, custody and compliance. But fragmented processes and enforcement stymie implementation of standards consistently across jurisdictions, SMX argues.

SMX focuses on material identity. Its molecular‑level marking technology allows gold to be invisibly tagged, creating a persistent physical‑digital link that survives refining and downstream processing. This enables verification of origin and authenticity without relying solely on paperwork or chain‑of‑custody declarations.

The partnership also addresses the human identity gap that has complicated compliance in the gold sector. FinGo’s biometric digital identity platform will be used to authenticate individuals involved in extraction, aggregation, refining and export, aligning identity checks with KYC and AML requirements. The aim is to ensure that each custody change or supply chain action can be attributed to a verified individual, even in remote or low infrastructure environments.

Bougainville Refinery Ltd will provide the operational setting for the pilot, testing the integrated system across real sourcing and export activities. The refinery’s participation positions Bougainville as an early jurisdiction exploring how digital identity and material authentication can be embedded into national level resource governance.

If successful, the pilot could serve as a template not just for gold but for other commodities.

Blue Gold, Trust Stamp to develop wallet for tokenized gold holders

Blue Gold Limited has signed a Letter of Intent (LOI) with Trust Stamp to develop a biometric, passwordless digital asset wallet designed for holders of the company’s gold‑backed digital tokens.

The planned system would act as a secure access layer for users of Blue Gold’s Standard Gold Coins (SGCs), which represent one gram of physical gold stored in Brink’s vaults under a Wyoming digital asset statutory trust.

“Blue Gold was founded to bridge physical gold with the digital financial system at institutional standards,” says Nathan Dionne, Blue Gold’s Chief Technology Officer.

“Following our recent announcement securing access to one million ounces of physical gold to support the initial issuance of Standard Gold Coins, the next priority is ensuring that access to those assets is governed by security and identity infrastructure that matches the quality and permanence of the gold backing them.”

The collaboration aims to integrate biometric identity verification and cryptographic key management into a non‑custodial wallet architecture. Trust Stamp will apply its patented biometric tokenization technology to bind wallet access to a user’s live biometric presence, without storing biometric data or private keys centrally.

The approach aims to remove reliance on passwords, PINs, seed phrases and other credentials that are frequently targeted in digital asset theft. “Trust Stamp’s identity and asset tokenization technologies are expressly designed for the digital economy,” says Gareth N. Genner, CEO of Trust Stamp.

“As gold-backed digital assets become more widely adopted, they require advanced security and privacy protections that go beyond traditional wallet architectures. We believe the Wallet-of-Wallets platform will provide Blue Gold’s customers with a level of protection and control consistent with institutional expectations.”

According to the companies, the proposed wallet would allow users to control their assets directly while providing identity‑based access controls, governance tools and recovery mechanisms. The architecture is being designed to support multi‑device access without duplicating sensitive credentials and to operate across multiple blockchains.

Trust Stamp’s Stable Key system, which is its method for generating cryptographically derived biometric tokens, would underpin authentication. The company says the design avoids centralized biometric or key storage by splitting encrypted helper data into separate shards stored independently, reducing the risk of compromise in the event of a breach.

Blue Gold’s broader strategy involves building a digital‑identity‑anchored infrastructure for tokenized gold, spanning sourcing, aggregation, token issuance and downstream financial applications. The partnership with Trust Stamp is intended to strengthen the identity and access control layer of that ecosystem.
