The tokenized-asset pages on this site state facts about tokens that track real securities. This page says where every one of those facts comes from, what is verified and how, and when a page changes. It exists because a financial-data page should be able to show its work.
No third-party tracker feeds this site. Each family of tokenized assets is admitted from its issuer's own published list or from on-chain discovery, and a row is only emitted after its token contract has been read back from the chain it lives on. The 7 issuer programs and their admission paths, family by family:
An underlying the issuer delists drops out of the registry on the next rebuild of the site rather than lingering as a stale row. When several issuer programs tokenize the same company, each form keeps its own page, because contracts, transfer rules, and settlement chains differ even when the exposure is identical; the company's comparison page holds them side by side.
Contract addresses, token standards, issuers, and ISINs are carried from the issuer-published data and checked against the chain at generation time. On-chain facts such as supply, mint and freeze authorities, and configured extensions are read from the chain itself, not from marketing copy. Where a fact cannot be verified, the page omits it rather than guessing: a form without public filings says so, and a currency without an on-chain peg is listed with none.
Tokenized assets do not price from a crypto market. Each family reads its own source: Backed xStocks and bStocks forms on BNB Chain read the token's on-chain pool price, Base forms read the token's on-chain price feed, Robinhood Chain forms read the issuer's feed, and Solana forms read the token's on-chain market. Every asset page states which basis applies to it, and live quotes always come from the swap preview at trade time, never from this site's static pages.
Public filings come from the U.S. Securities and Exchange Commission's EDGAR system for the underlying company, linked from the pages of every form that tracks it: 226 underlyings carry filings today. The filing identifies the entity the token tracks; the token is not issued by it, is not a brokerage holding, and carries no ownership, voting, or dividend rights unless the issuer program grants them. Pre-IPO underlyings have no public filings by nature and are marked as SPV-backed exposure instead.
Every page carries a last-modified date that moves only when the page's own content moves: a roster change, a contract fact, a corrected figure. Rebuilding the site without a content change keeps every date where it was, and cosmetic changes to shared page furniture never advance one. The dates exist so a reader can judge freshness, not so the site can look newer than it is.
If a fact on a tokenized-asset page is wrong, it gets fixed at the source data and the page regenerates, which is the only path by which these pages change. Write to contact with the page and the discrepancy; verification happens against the chain and the issuer's records, not against this site's own copy.
