What exchange reserve reports do and do not tell an NFT collector

Many NFT collectors keep part of their funds on an exchange: ETH waiting for the next mint, stablecoins from a recent sale, or even NFTs bought through an exchange's own marketplace. Exchanges such as Binance, OKX, Bybit and Bitget publish proof-of-reserves reports intended to show that customer assets are backed. Those reports are useful, but they are narrower than many people assume. They usually cover a list of specific tokens at a particular moment, and they may not include NFTs, assets in certain products, or liabilities outside the snapshot. This guide explains what a reserve report typically measures, where NFT-related holdings may fall outside it, how to check that your own balance was included, and how to use the report as one input among several when deciding where to keep funds.

What a reserve report usually measures

A proof-of-reserves report generally compares the exchange's holdings of selected assets with the total customer balances of those same assets at a snapshot date. Customer balances are often committed to a cryptographic structure called a Merkle tree, which lets each user check that their balance was counted without revealing anyone else's. The report typically shows a reserve ratio per asset. It is a point-in-time view, not continuous monitoring, and the exchange decides which assets to include. Reading the methodology section tells you which tokens, products and dates the report actually covers.

Where NFT holdings may fall outside the report

Reserve reports focus on fungible tokens with large customer balances. NFTs held in an exchange's marketplace account are unique items and are rarely part of a reserve ratio, because there is no simple way to sum them. Balances locked in certain earn products, launch events or other programmes may also be listed separately or not at all. If you hold NFTs on an exchange, do not assume the report proves they exist on chain under the exchange's control. Check the marketplace's own documentation on how NFTs are stored and whether you can withdraw them to your wallet.

Verifying your own balance was included

Most exchanges that publish reports provide a verification page inside your account where you can see a record identifier and the balances counted for you at the snapshot. Some also offer open-source tools that let you check the Merkle proof independently. Compare the balances shown with your own records for that date, keeping in mind that only the listed assets will appear. If something you expected is missing, read the methodology to see whether that asset or product was excluded before contacting official support through the app.

Using the report as one input among several

A strong reserve ratio is reassuring, but it does not describe the exchange's total liabilities, its operational security or how it would handle extreme events. Look at how often reports are published, whether an independent firm was involved and how clearly the limitations are explained. For NFT collectors, the most practical protection remains keeping only what you need for upcoming activity on the exchange and moving long-term holdings, including NFTs you intend to keep, to a wallet you control once you are comfortable managing its recovery phrase.

Digital assets are volatile and derivatives can amplify losses. This website has no login, wallet connection, deposit form or customer-support chat.

Scenario checkpoint

• Read the methodology section to see which assets, products and snapshot date the report covers.
• Do not assume NFTs held on an exchange marketplace are included in any published reserve ratio.
• Use the verification page in your account to confirm your balances were counted at the snapshot date.
• Note how often reports are published and whether an independent firm reviewed the figures.
• Keep only near-term mint and trading funds on exchanges and move long-term NFTs to your own wallet.
