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 was founded in 2018 to digitize, by issuing fungible ERC-20 tokens, uniquely tracked gold bars in a transparent and fully backed manner using GramChain asset tracking system, thus providing a real-time and tamper evident Proof of Reserve (PoR).

Our approach was compliant to the definition of an asset-backed-token under the Singapore Precious Stones and Precious Metal Act (PSPM Act) as administered by the Singapore Ministry of Law.

In mid-2023, Singapore Ministry of Law announced the proposal to amend the PSPM Act whereby “the definition of asset-backed token will be updated to exclude digital payment tokens” and that “[sale of] tokens backed by gold to a customer after the effective date of this amendment, will not fall within the scope of regulated dealing under the PSPM Act.”

With these changes, gold backed tokens, from a regulatory perspective will be regarded as securities under the Monetary Authority of Singapore (MAS). MAS securities regulations makes the issuance, distribution and trading public blockchain tradeable tokens impractical.

This shift removes the regulator assurance of issuing new CACHE Gold Tokens in Singapore and as a result, CACHE Gold has made the difficult decision to enter indefinite dormancy, with the aim of just facilitating 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.
