How to Update a DeFi Safety Bookmark Set
A recurring maintenance routine for domains, explorers, documentation and support links.

A bookmark set is a private trust infrastructure, and it decays quietly. Domains expire and get re-registered. Documentation gets reorganised or replaced by a support platform nobody migrated. Explorer interfaces redesign around features you rely on. None of this produces an error; the bookmark simply starts taking you somewhere that used to be authoritative and is now something else. Updating the set on a schedule is what separates a maintained list from a list of plausible-looking links that quietly stopped being true.
Treat the set as four categories, because each fails differently and each needs a different check.
Official domains
For every protocol in your set, the recorded domain is the single highest-value entry
and the single most dangerous to get wrong. Domain expiries are a recurring pattern in
DeFi, particularly for projects whose organisations have wound down: a .org or .xyz
registration lapses and is then re-registered by someone who rebuilds a convincing
front page with a certificate icon and a Twitter handle.
The check is not “does it load”. It is “does it still belong to the same party”. Look for the documentation link from a source you already trust rather than from search results, confirm the domain is the one you recorded rather than a variant, and check whether the project has moved to a different domain entirely — legitimate migrations are announced on the project’s own channels and reflected in its documentation, and an unannounced change of domain is a finding worth investigating before you use it.
Explorers
Keep at least one explorer per network you use, plus the network’s own name and chain ID recorded next to it. The reason to keep a second one is specific: explorers redesign, and the redesign is not always an improvement for verification work. Functions move, the transaction list truncates earlier, internal transactions get hidden behind a toggle that defaults to off, and a view you relied on for years becomes a filtered subset without saying so.
Verify a specific capability rather than the page. Open a recent transaction of a type you care about and confirm you can still see the decoded input, the full list of transfers including internal ones, and the contract you interacted with. If the view now hides any of those by default, note where the toggle is before you need it in a hurry.
Documentation
Documentation is where staleness actually causes harm, because instructions age silently. Record the URL and what it was useful for, then re-check on a schedule whether that specific instruction still matches the interface you use.
The failure to watch for is a documentation page that describes a feature version behind the one you are running. Protocol interfaces ship major redesigns several times a year, and permission prompts, confirmation modals and gas handling all move between releases. A page that is accurate and two versions stale is worse than no page, because it gives you confidence about the wrong interface.
Support links
Support URLs deserve the most suspicion and the least trust, for a structural reason: official help content is often hosted on a third-party platform, and old instances are frequently left accessible after a project migrates to a new one. An abandoned help centre still ranks in search results, still reads as authoritative, and still documents an interface that no longer exists.
Record which help centre the project currently links to from its own site, and treat any unlinked instance as unattributed regardless of how official it looks. Where a project’s support has migrated, close the old bookmark — an unclosed stale help link is a live phishing surface.
Running the update
A quarterly cadence is enough, and shorter intervals do not help if you are only confirming links load. Use the pass to ask three questions per entry: is this still the same party, does this still describe the version I use, and have I used this in the last six months.
That last question is the one that shrinks the set. Entries that have not been opened in six months are not bookmarks you need; they are links that will feel authoritative the first time an attacker-controlled result sends you to the habit of clicking something that looks like the tool you remember. Deleting them is maintenance, not loss — the set is more useful smaller and current than larger and plausible.
