Install manually below. Chrome Web Store release pending.
One install. Your call from there.
- 01
Extract the download
Keep the extracted folder somewhere permanent. If you installed 0.1.0, replace its files with 0.1.1 and reload the extension.
- 02
Load the extension
Open
chrome://extensions, enable Developer mode and choose Load unpacked. Select the folder containingmanifest.json.Edge:
edge://extensions. Brave:brave://extensions. - 03
Pin. Open. Check.
Pin Quick Check from the extensions menu. Open a token page, click Scan this page, then choose an address. You can also paste a CA or use the right-click selection menu.
Installed-browser tests passed on Chrome for Testing 151. Edge and Brave have not been separately tested. Mobile browsers are not included in this build.
Check this first.
The page cannot be scanned
Browser settings pages, the extension store, PDFs and some protected pages block access. Paste the full address into Quick Check. For embedded content, open the original page in its own tab. A selection inside an editable field is ignored.
It asks me to choose a network
A bare 0x address can exist on several networks. Choose BNB or Robinhood Chain explicitly, or paste a supported explorer or pool link. Test-network links are rejected.
Holders or contract checks are missing
That means the source is unavailable or the count has not been independently verified. A provider sample is not a full holder census. Quick Check can show market data even when other checks are missing. Open Sources & what is missing for the detail.
A wallet link sends me to the main app
Quick Check recognizes supported public account links locally. Wallet research opens the holder-only KOL directory. A pasted address does not prove who owns it or unlock holder access. Live KOL collection still depends on separate production integrations.
Does it scan in the background?
No automatic page scans or market polling are installed. Each scan is a single action on the current page. Select the address you want before a research request is sent.
Your page stays in your browser.
A manual scan processes visible page text, links and page context locally. It skips forms, editable fields, hidden content and frames, including when your selection crosses them. Scans are bounded; they do not claim to find every address on a page.
No page text, title, original URL, screenshot or browsing history is sent by the quick-check request.
Radar receives the chosen public identifier and schema version to return a summary. No cookies, Radar login or wallet credentials are attached.
Storage, providers and request metadata
The selected-text menu passes filtered, parsed candidates through browser session memory. They are removed when consumed and cannot be used after one minute. If the popup never opens, expired candidates may stay in session memory until the browser session ends. They are not synced.
The public Radar endpoint obtains lookup data from DEX Screener, RugCheck and GoPlus as available. Those services receive the public lookup identifiers needed for the request. They do not receive your scanned page text from Quick Check.
Hosting and network services receive ordinary request metadata, including IP addresses. The application uses minute-scoped hashed IP limits for abuse prevention. Rate-limit records have a two-minute expiry and are cleaned up by later requests; public summary responses may be cached for up to one minute. These timers do not describe hosting-log retention or imply network anonymity.
The extension contains no analytics or advertising code. Opening the full app or a source link is a separate navigation. The main website can then use its normal login and account features. Nothing in Quick Check connects a wallet, signs a message or places a trade.
You control each scan and lookup. Closing the popup discards its in-memory view; disabling or uninstalling the extension stops future extension activity.
