Today, stablecoin and tokenized asset issuers prove reserves with a periodic snapshot, and often have to show the data behind it. That leaves the time between reports unproven and exposes custodian and holder data to auditors. With Zero-Knowledge Proof of Reserves on zkDatabase, an issuer proves that reserves cover every holder balance at every reserve update, and lenders and DeFi protocols check that proof on-chain between reports. This keeps reserves transparent to them and protects the privacy of that data.
