Tested and Guaranteed

CACHE and its partners have many years of experience in testing of precious metals. We implemented standardized testing processes within our partner vaults to make sure that any stored metal is pure. While it is possible to pass one specifick testing method with a fake bar, it is impossible to trick different combined tests. We combined the follwing testing methods to make sure that everything is real:

  • Density Test
  • Ultrasound Test
  • X-Ray Flourescence Test
  • Electrical Conductivity Test

Through our excellent testing methods and our trained staff, we can guarantee that every cash and every coin we store is genuine and will buy them back ourselves at any time.

CACHE Gold Testing


Any items within the vaults is fully insured against internal or external theft or against mysterious disappearance. Therefore, as a customer, you can rest assured even if the item would be lost. In addition, we have very high security standards, area-wide video surveillance and auditing.

Competitive Pricing

Running a vault is a costly affair because IT systems, space, security personnel, warehouse staff, administration and other costs have to be paid for. But the bigger the vault, the less these costs matter. The Reserve is one of the largest vaults in the world. Therefore we are able to offer low prices for very high quality.

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.
