A digital warehouse receipt answers "is the cargo there, and is the title clean," but a bank still asks "if it's lost, who pays." Tying title insurance to the receipt adds an insurance backstop on top of the on-chain credential.

The method is straightforward: when the receipt is created, the SHA-256 hash writes in the bill-of-lading number, the storage lot and the insurance policy subject code together. The policy covers loss of and disputes over that title right, and its claim trigger is wired to the receipt's state machine — once the receipt is marked "delivered," the policy lapses automatically, blocking empty-receipt fraud.

For the bank, a bare receipt pledge needs a fat haircut for value swings and title risk; layer on title insurance and that risk shifts to the underwriter, letting the loan-to-value ratio rise by 5–10 points. On a 50,000-tonne ESPO receipt the extra draw is a meaningful sum.

The bigger win is the leak plugged. The hash locks receipt, policy and title into one chain, so tampering with any one end fails to reconcile with the other two. Duplicate pledging and double-selling are blocked by the technology before human due diligence even begins.
