Build your product with CACHE

With CACHE’s services and APIs, you can easily create, manage, and transfer tokens backed by physical assets which can be integrated with new or existing systems. By tokenizing physical assets, you can unlock new revenue streams and provide more transparency for your customers.

CACHE’s Data is Publicly Auditable

CACHE's tokenization data is public and can be audited via the CACHE Explorer. This data can include test results, images of the assets, serial numbers, NFC data and more. This empowers anyone to become an auditor and greatly increases the chance that any unlikely improprieties will be identified and resolved quickly.

Immutable Data Events

Each event’s data is hashed and broadcasted in real-time to a public blockchain. Raw event data is also available in JSON format. The complete history of every asset can always be traced and validated by anyone with access to an internet connection and a web browser.

How it works?

CACHE’s tokenization process utilizes a multi-layer infrastructure solution including vaults, GramChain and public blockchains to maximize security and transparency. On top of our infrastructure you can build your own B2B or B2C application, platform or service. The complexity of storing, testing and shipping physical assets is handled effortlessly by CACHE's infrastructure.

Important Notice:

CACHE Gold, established in 2018, embarked on a mission to digitize gold through the issuance of fungible ERC-20 tokens, utilizing the GramChain asset tracking system. This innovative approach offered a transparent and fully backed solution, providing real-time and tamper-evident Proof of Reserve (PoR).

Recent regulatory changes and proposed amendments are expected to significantly increase our compliance and administrative costs, rendering the issuance of new gold backed tokens in Singapore unfeasible. In light of these developments, CACHE Gold has made the difficult decision to enter indefinite dormancy. This move is aimed at addressing the operational complexities arising from the recent and potential regulatory shifts. Our primary focus during this period of dormancy will be to facilitate the redemption/conversion of any remaining tokens.

If you hold any outstanding CGT, please contact us at [email protected] for guidance on CGT redemption/conversion.

CACHE Gold has consistently maintained more than 100% backing for its tokens and possesses adequate net assets to responsibly close operations, settling all liabilities. We have actively reduced outstanding tokens and hold only a minimal number of third-party tokens.

We deeply regret being unable to realize our vision of issuing highly transparent public blockchain gold tokens.
