● Chrome extension · built for Fomo Web
The Fomo chart
won't show you this.
Six wallets, one funder, one block. SONAR reads the launch transaction itself and puts the answer on the token page you are already looking at — no second tab, no pasting addresses.
Free · no account · Solana and six more chains
Live
It fills in while you are still reading the chart.
SONAR answers in three passes instead of making you wait for one slow
one. Nothing is ever guessed to fill a gap — a row says
checking… until it has a real number.
-
01
Holders and authorities ~0.4s
Who holds it right now, with pools and program accounts removed, and whether anyone can still mint, freeze or seize.
-
02
The launch itself ~1.6s
The creating transaction is read directly: what the dev took, who bought in the same block, who bought in the first ten seconds.
-
03
Wallet by wallet ~3s
Every wallet in the launch window is traced back to what funded it, which is how a bundle stops being a coincidence.
SONAR

A recreation of the panel, running at the speed it actually answers.
Inside Fomo
Install once. Then it is simply there.
SONAR does not ask you to change anything about how you trade. It waits on Fomo token pages and shows up when you open one.
-
01
Add it to Chrome
One click from the Web Store. No account, no wallet connection, no settings screen — there is nothing to configure.
-
02
Open any token on Fomo
Trade exactly as you do now. The panel appears in the corner of the page on its own, on every chain it covers.
-
03
See it before you buy
The first numbers land in seconds, while the chart is still in front of you. Drag the panel anywhere; it stays where you put it.
It runs on fomo.family and nowhere else — not a limitation we
are apologising for, but the point. An extension that can only see one site
can only ever do one thing.
What it checks
Six things the Fomo chart cannot tell you.
Every number here comes from the chain — the launch transaction itself and everything that moved in the seconds after it.
Precision
Numbers you can check, not a score you have to trust.
Every figure is read from the chain and shown with its working. Liquidity pools, burn addresses and program accounts are removed from concentration, because counting a pool as a holder makes every healthy token look rugged. Bundlers and snipers are kept apart, so one wallet is never counted twice.
Permissions
It runs where your wallet is. So it does almost nothing.
The entire permission list is three lines and you can read all of it.
No tabs, no cookies, no webRequest,
no access to any site but Fomo.
- ✕ Never touches your wallet or signs anything
- ✕ Never reads cookies, storage or session data
- ✕ Never clicks, types or submits on the page
- ✕ No analytics, no tracking, no remote code
"permissions": ["storage"], "content_scripts": [{ "matches": ["https://fomo.family/*"] }]
The whole of it. storage remembers where you dragged the panel; nothing else is kept, and nothing leaves your browser except the token's address.
Coverage
Seven chains. Not just Solana.
Switch between the chains below and the panel follows. Same panel, same numbers, read natively on each — the launch from the block itself on Solana, from the token's own transfers everywhere else. Not one chain with the rest bolted on. Fomo lists more, and the rest are coming.
And when a token is clean, it says so plainly: the dev still holding, nothing bundled, authorities revoked. A green panel here is one you can act on, because it was measured rather than assumed.

Monad
Arc
Robinhood
Side by side
The same token, three ways of looking at it.
Everything SONAR reports can be found by hand. The column that matters is how long it takes, and whether you will actually do it before you buy.
SONAR adds to the page. It never covers, changes or reorders anything Fomo already shows you, and it reads the chain directly rather than repeating another service's verdict.
Ready to install
Three seconds, before the buy button.
Add it once and every Fomo token page answers for itself after that. You will not change how you trade — you will just stop finding out afterwards.

Questions
The ones worth asking before you install anything.
This runs on a page where you hold money. You should be suspicious of it, and the answers should survive that.
Do I have to connect my wallet?
No — and it could not use one if you did. The extension has no wallet access, cannot sign, approve or send anything, and never reads the page's wallet state. It reads one thing: the token's address.
Does it slow Fomo down?
No. The whole extension is around 30 KB and it adds one element to the page. It never modifies Fomo's own markup, never patches its navigation, and the panel lives in a closed shadow root so its styles cannot reach Fomo and Fomo's cannot reach it.
How fast is it?
The first numbers — concentration and the authority checks — land in about two seconds. The launch checks follow, and per-wallet detail after that. You never wait on a blank panel: rows say "checking…" until they have a real answer.
Which chains does it work on?
Seven of them today: Solana, Base, BNB Chain, Ethereum, Monad, Arc and Robinhood Chain. Each is read natively rather than one chain with the rest bolted on. Fomo lists more than that, and the remaining ones are being added — on a chain SONAR does not cover yet, no panel appears.
What do you collect about me?
Nothing. One request leaves your browser and it carries the chain name and a public token address — no cookies, no credentials, no wallet address, no page contents, no identifier. The only thing stored on your device is where you dragged the panel.
Can I trust every number it shows me?
Yes — that is the whole design. Every figure is measured from the chain before it is printed, and SONAR tells you exactly how much of a token it was able to measure. Nothing is ever filled in with a guess or rounded down to a comfortable zero, so a number on the panel is a number you can go and verify.
Can it see my other tabs, or any other site?
No. Chrome enforces this, not our good intentions: the extension
declares one match pattern, https://fomo.family/*, and
Chrome will not run it anywhere else. There is no tabs
permission, no <all_urls>, no history access.
Is it really free?
Yes, and there is no account, no sign-up and no trial. If that changes it will be for features that do not exist today, and the panel you are installing now will keep working.
Can I move it, or get it out of the way?
Drag it by its header anywhere on the page and it stays where you put it, on every token page afterwards. The minus button folds it down to a single bar.
How do I know the code does what this page says?
Read it. The whole project is public, the permission list is three lines long, and there is no remote code — nothing is fetched and executed at runtime, so what Chrome reviewed is what runs. Open the source →
