Which exchanges have issued this stock token asset? Where is it custodied? How can I check?
The on-chain tokens of the same stock often have more than one version—versions issued by exchanges and those by professional issuers, each running on different chains with different custody arrangements. Whether researching this asset, understanding its structural information, or simply wanting to find out "who is behind this version," the first step is the same: to find out its issuer and custody information.
Who is this article suitable for?
- Analysts and researchers who study individual assets and need to verify the issuance structure;
- Media authors following tokenized assets;
- Investors holding tokens who want to understand the versions they hold.
Query path: Search for the asset → Detail page → Tokenized stock asset module
Open Tokenized asset dashboard , search for the asset name to enter the detail page—taking QQQ as an example, the "Tokenized stock asset" module displays all versions of the same asset side by side: the issuer, the chain, the price, the issuance volume, and AUM for each version. The question you asked, "which ones have been issued and where are they custodied," this screen is the query entry.
After finding it, check what
the issuer is. The issuer names in the version list distinguish between exchange self-issued versions and professional issuer versions. The public information of the issuer is the first layer of material to understand the background of the version.
Where it is issued on which chain. The choice of chain is related to the user base and transfer costs of that version; the liquidity conditions may differ for the same issuer's versions on multiple chains.
Issuance volume and AUM. The specific meanings of these two numbers vary depending on the product structure design, and should be interpreted according to the issuer's documents.
Custody arrangements. This is an important aspect of understanding the version structure: which institution is custodian of the underlying stocks, and how reserve proofs are published. The issuer information on the page is aggregated, and custody details should be verified according to the official disclosures of the issuer—after finding the issuer's name, it is recommended to check their official website for the latest custody and reserve announcements.
Price differences between versions. When prices of various versions are displayed side by side, if a certain version consistently differs from others, it may be caused by liquidity, redemption arrangements, and other factors, and should be judged in conjunction with issuer information; when citing price data, the version being cited should be specified.
