Get started
Record a Custody Event
For officers. Record a lot's origin, assay, or export, and queue it for on-chain anchoring.
Open the custody form →Transfer Custody
For the current custodian only. Hand a lot off to another tenant in the chain.
Open the transfer form →Confirm Receipt
For the receiving tenant only. Acknowledge a lot has arrived — this is what actually completes a transfer.
Open the confirmation form →Verify a Lot
For anyone — buyers, officials, the public. Check a lot's full custody history across every tenant that has held it.

How it works
01
Hash
Every custody event is fingerprinted with SHA-256 — without exposing the underlying trade data publicly.
02
Anchor
Fingerprints are batched into a Merkle tree and confirmed on the BSV blockchain — permanent, public, tamper-evident.
03
Verify
Anyone can recompute a lot's current hash and compare it to what was anchored — a match proves nothing has changed.
