How to Maintain a Change Log for an RWA Product Page
How to keep an RWA product page change log that stays trustworthy: what belongs in each entry, the five-field format with before-and-after values, and what a change log cannot establish about a page's current accuracy.

A tokenized real-world asset page is not a document you publish once. The terms, the reserve figures, the eligibility rules, the redemption path and the risk disclosures behind it all change on someone else’s schedule, and they usually change without notice to the page that describes them. A change log is the mechanism that keeps a reader able to tell what they read last month from what is true now.
The reason this matters more for RWA pages than for ordinary documentation is structural. Tokenizing a real-world asset generally involves selecting the asset, specifying the token type and standard, choosing a network, connecting off-chain data including reserve verification, and then issuing the tokens. Steps four and five depend on off-chain parties — a custodian, an administrator, an issuer, an auditor — whose actions are not observable from a blockchain. The token address never changes even when every substantive fact behind it does. That asymmetry is exactly what a change log exists to correct.
What belongs in an RWA change log
Five categories, and the first two are where most pages fail.
Terms and legal structure. A change in the legal wrapper — from a direct holding to a bankruptcy-remote structure, from one SPV to another, from a custody arrangement to a managed one — changes what a holder actually owns. This is the most consequential edit a page can carry and the one most often presented as a footnote.
Eligibility and access rules. Who may hold the token, from which jurisdictions, under which investor classification, with what minimum ticket and what onboarding. These change when a regulator acts or when an issuer restructures, and marketing copy frequently outlives the legal text it summarises. Record the effective date, not just the wording.
Reserve and backing data. Attestation reports, proof-of-reserve checks, custodian statements, and their dates. A verified reserve says the assets exist; it says nothing about who may own the token, and a reserve figure without a date is not a fact but a rumour with a decimal point.
Redemption and settlement mechanics. Minimum redemption size, settlement window, the chain on which redemption occurs, the identity of the party that processes it, and any lock-up or notice period.
Links and disclosures. Every outbound reference should be recorded with the date you last confirmed it resolved. Documentation moves; a citation without a date is an unverifiable citation.
The entry format
Keep entries small and uniform. A workable entry has five fields:
- Date of the change as stated by the source, and separately the date you observed it. These are frequently different, and conflating them is how a page ends up claiming to be current when it is describing a page that was accurate some weeks ago.
- Category, from the five above.
- What changed, stated as a before and after rather than as an adjective. “Redemption minimum reduced from 100,000 to 50,000 units” is an entry. “Improved redemption flexibility” is not.
- Which source the change came from, with a URL or a document reference and its own date.
- Whether the page was updated, so a reader can tell the difference between a change that has been reflected and one that is still pending.
Rules that keep the log trustworthy
Never edit an entry in place. Correct by appending a new entry that says what was wrong. A log that has been rewritten is indistinguishable from a page that was never wrong, which destroys the only property the log has.
Record silence as well as change. If a source stopped publishing and nothing replaced it, that is an entry. The absence of an update from an issuer is itself information a reader needs.
Do not describe the change’s significance. Log what the source says, and keep your assessment out of the entry. A change log is a timeline; interpretation belongs elsewhere and changes as your understanding does.
Keep the log on the page, not in a separate document. A log that requires a second visit is a log nobody reads.
Date every claim you carry over. Anything you restate from a source inherits that source’s date, and the two must be shown separately.
What a change log cannot establish
It cannot tell you whether the current terms are favourable, only what they are and when they moved. It cannot tell you whether a reserve attestation covered the period you care about; attestation frequency is not coverage. It cannot tell you whether the off-chain administrator is solvent — that information exists, if anywhere, outside anything an on-chain reader can inspect.
It also cannot retroactively protect a reader who acted on an earlier version. That is the honest limit of the exercise: the log makes the sequence of facts visible, and visibility is what lets a reader notice that the ground moved.
