Commodity Chain of Custody

Provenance you can verify. Liquidity that reaches the mine.

Nelum registers and verifies every actor in critical commodity supply chains — from artisanal gold to precious stones — and connects that verified chain to institutional demand through a demand-pull order book. Compliance and capital, moving together.

One platform, three foundations

Verifiable chains need three things: a shared map of how custody moves, tools every actor can actually use, and compliance knowledge translated into practice.

Supply Chains

Two commodity families, mapped end to end — every custody transfer, every audit checkpoint, every document. The macro-chain matrix is the reference the platform is built on.

We give the chain its tools

Provenance fails at its weakest link, and the weakest link is the first mile. So the first mile pays nothing: every miner, assayer, and field buyer can claim a verifiable Nelum ID with a scannable QR code, issue digital assay receipts, and keep KYC purchase logs — free.

The commercial engine

Demand-pull, not push

Traditional brokerage negotiates fixed quantities boardroom to boardroom while capital sits idle. Nelum inverts it: committed buyer demand at the top of the chain cascades down through verified regional supply chains, so legitimate producers source against real orders — and compliance becomes the price of market access.
