Raw stock verified before it ever left the vault floor.

Raw stock moving between counterparties on trust alone.

Meridian was taking gold and silver lots from four suppliers and moving them straight into production. Purity was accepted on the supplier's own paperwork, and one bad lot would have contaminated an entire batch.

Their insurer would not schedule the stock at all without an independent purity record behind it.

Verify on arrival, hold, then release.

Every incoming lot is assayed by an outside laboratory before it enters allocated custody. Nothing reaches production without a certificate attached to that specific movement.

Armored transport is arranged on both legs, and release requires two authorized signatories on Meridian's side as well as ours.

480 kg verified, no rejected batches.

Meridian now runs production against verified stock only. Their insurer schedules the holding directly from our records, and the reconciliation between our count and theirs has matched at every audit since.

One record both sides can read.

Supplier disputes are now settled against the assay certificate instead of argued over email. Two of Meridian's suppliers have since opened their own custody accounts.
