Lens

QuantBase Lens reads the coin you are looking at and shows what the launch record knows about it: how the launch filled, who launched it and how their money was funded, whether it is a clone, how the curve would treat an order of your size, and the base rates. It is the same evidence as the console's coin page, on the page you already use.

It is evidence, not a signal. Lens never tells you to buy.

Install#

Lens is built for Chrome 116 or later (and other Chromium browsers such as Brave and Edge) and Firefox 121 or later. It is free and needs no account. The store listings are not live yet, so for now you load it directly:

1. Download the zip from quantbase.live/lens and unzip it.
2. Open chrome://extensions (or brave://extensions, edge://extensions).
3. Turn on Developer mode and click Load unpacked, then pick the unzipped folder.

The code is plain, unminified JavaScript. Firefox users will get it from Firefox Add-ons once the listing is approved.

After installing, open the Lens popup from the toolbar to set:

• Order size, in SOL (default 0.1). Used for the curve-depth figures.
• Sites: turn Lens on or off per site.
• Panel position.

The popup also has a manual lookup for any address.

Where it works#

System addresses (wrapped SOL, the token program, the pump.fun program) are ignored.

What it shows#

• Verdict: avoid, a caution count, or nothing adverse on record.
• Flags: a bundled self-buy graduation (under two seconds), a repeat creator, a funding cluster with a rug history, an image clone, a paid DexScreener boost, an order that would move the curve more than 5%, a curve that could not pay your order back, and a coin under five minutes old.
• Fillability (coins still on their curve): the price impact of your order size, and how many times over the curve's real SOL covers it.
• Base rates over the last 14 days: organic graduation, and the chance a coin was up an hour and a day after an organic graduation.

Each flag is defined on Coin evidence. Coverage starts on 2026-09-20 and covers pump.fun launches only. A coin the record has never seen is looked up once on pump.fun; if that finds nothing, Lens says it is unknown.

What it sends#

One request per coin, and only this:

GET https://quantbase.live/lens/<mint>?size_sol=<your order size>

No page content, browsing history, account, cookies or identifiers. Answers are cached in the extension for 30 seconds. Lens has no wallet integration and cannot sign or send anything.

Permissions: storage for your settings, access to the sites above so the panel can appear on them, and quantbase.live to fetch the evidence. Your settings are kept with the browser's extension storage; if your browser syncs extension settings to your browser account, they sync with it.

Privacy#

QuantBase's server keeps standard request logs (client IP address, time, the address requested) for at most 14 days, used only for rate limiting and abuse prevention, not sold, shared or joined with other data. Full policy: quantbase.live/lens/privacy.

The API#

The endpoint Lens uses is public:

curl -s "https://quantbase.live/lens/<mint>?size_sol=0.1"

• No key and no plan needed. CORS is open.
• size_sol is optional, greater than 0 and at most 100. Default 0.1.
• Answers are cached for 30 seconds.
• 60 requests a minute per client, shared with the public feed. Over that, 429.
• An address that is not a Solana mint returns 400.

The response has known, summary (the verdict), flags (each with a level of red, amber, green or grey and a text), and the sections token, creator (with its funding cluster), metadata (socials and name, ticker and image matches), attention (boosts), market (curve and post-graduation pool), fillability and base_rates.

Evidence, not advice. A coin with no flags can still go to zero.
