Custom solutions for your product.
Tokenizing gold at scale takes trusted, compliant infrastructure that bridges physical metal and on-chain supply. Built in-house, that’s a multi-year program — sourcing, LBMA-grade refining, allocated vaulting, banking rails, and reserve attestation.
The alternative most issuers reach for is backing their token with someone else’s. Faster, but every reserve you hold is a competitor’s product. MyTresor is pure reserve infrastructure.

FAQ
Frequently asked questions
MyTresor partners with several LBMA-accredited refiners in Europe, Asia and the U.S. for access to precious metals, liquidity provisioning, and custody relationships in 40+ countries. Our widespread market relationships and access let us manage the requirements of complex precious-metals product offerings.
The LBMA protects the interests of those who buy and sell precious metals by assuring the quality of what is traded on the Loco London market. It accredits the supply of precious metals by assessing the robustness and veracity of the third-party assurances required of refinery management systems, and in doing so helps the industry meet acceptable standards.
MyTresor partners with a number of LBMA-approved custody providers in 40+ countries and works with you to find the best solution to open your custody account. Every custody account has a supported off-chain Proof of Reserve solution built in, is held in your name, and is insured to full value. Combined, our trading and custody solution results in over 90% of transactions being processed instantly.
You need a clearly defined product idea. If you are unsure how we can support your product offering, get in touch and we will help you scope it.
MyTresor emits per-issuer cryptographically signed reserve events tied to vault receipts, which your contract or a Chainlink Proof-of-Reserve feed can verify on-chain. A public proof-of-reserves methodology page is on the roadmap.
Fast integration.
Long-term partnership.
