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.

Open the form

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.

Live: the Proof of Collateral card on a verified asset.

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.

Upload attestation reports, custodian statements and constitutional documents.
