How to Compare Official DeFi Documentation Versions
A simple process for recording changed instructions, interfaces and risk disclosures.

Documentation gets rewritten quietly. A protocol can change a fee, a contract address or an approval flow without ever announcing it, and the help article you saved last year can now describe a screen that no longer exists.
Why version drift matters
Protocol documentation has no single canonical archive. A support article, a GitHub README and an in-app help screen can all describe the same feature and disagree on a detail that matters, such as the default slippage tolerance or which token must be approved first.
Because search engines index all three, you can land on a page that is two years out of date and read it as current guidance.
The practical consequence is that a guide which was correct when written becomes a hazard when a user follows it against a live interface.
What version drift looks like
The most common changes you will meet:
- A contract or proxy address replaced after an upgrade.
- A fee parameter renamed or given a different default.
- An approval step added or removed in the interface.
- A withdrawal or unstaking delay changed from hours to days.
- A support article split into several sub-pages.
How to run the comparison
Pick one protocol and one page. Do not compare whole documentation sets.
- Open the live documentation and record the last-updated date if the page shows one.
- Find the same instruction in a second place: the app itself, the GitHub repository, or a dated blog post from the protocol.
- Note every difference in a table with three columns: item, current text, older text.
- Classify each difference as cosmetic, numeric, procedural or safety-relevant.
- Treat safety-relevant differences as blocking until you confirm them in the app itself.
Numeric differences deserve the closest attention. A slippage tolerance that moved from 0.5% to 5% changes the worst case a user can accept, even though the wording looks nearly identical.
Recording the result
Write the comparison down with a date. A short note prevents you from repeating the work six months later.
Keep the source URL, the date you checked, and one line describing what changed. If nothing changed, record that too. A negative result is still evidence.
Limits
This method does not tell you which source is correct. It tells you that they disagree, which is the part you can act on. Resolving the disagreement requires reading the live interface or asking the protocol team.
Never treat a documentation page as a guarantee about protocol behaviour. Confirm anything that would move funds against the interface you are actually using.
