[Proof of Collateral](/tools/proof-of-collateral) shows what backs a token: the reserve composition, the collateral ratio, how redemption works and the documents behind it. You publish it through the asset disclosure form on a KYI-verified asset. Design of an asset page showing KYI Verified and Proof of Collateral. In **My Assets**, open the asset. On the **Proof of Collateral** card, click **Start form**. Passport asset page with the Proof of Collateral card and its Start form button. If Passport can't read the collateral on-chain, the card says so. The form doesn't depend on that read, so you can still open it. Enter the collateral type, each reserve asset with its amount, the current collateral ratio and the redemption process. Upload attestation reports, custodian statements and constitutional documents. Check the summary and submit. Once approved, the disclosure appears on the asset's public page. Drafts and disclosures under review never appear publicly. Only the approved disclosure is shown.
