Works on X, Axiom, GMGN & Padre
Is the narrative
actually real?
Most memecoins are selling you a claim about the real world. FastCheck looks that claim up and tells you what it found, in about five seconds, without you leaving the page.

Fact check
Setting it up takes about a minute
01
Sign in with Google
There is no form to fill in. You land on a dashboard with your token on it.
02
Install the extension
Get it from the Chrome Web Store and paste your token into the one field it asks for. You will not have to do that again.
03
Click FastCheck on a post
The button sits under every post on X, and inside the coin pop-ups on Axiom, GMGN and Padre.
It looks for the one factual claim in a post
Price predictions and a dev's promises about their own coin are not facts yet, so FastCheck skips them and goes after the thing the narrative is actually built on.
TRUE
Credible evidence backs it up — an official source, a primary document, or on-chain data. It does not have to come from a big news outlet.
FALSE
Something FastCheck found actually contradicts the claim. A claim never gets marked false just because nobody has written about it.
UNVERIFIED
There is a real claim here, but nothing public settles it either way. Usually a private wallet, or a listing nobody has announced.
NO_CLAIM
Hype, jokes, or the dev saying what they will do with their own fees. There is nothing in it that can be true or false yet.
Safety
It never touches your wallet
FastCheck reads posts. Every line below is something you can confirm for yourself from the permissions Chrome shows you before you install it.
No wallet, ever
FastCheck never asks you to connect a wallet, and it contains no code that can read, sign or send a transaction. There is nothing in it to approve.
It can only reach six sites
The extension asks Chrome for local storage, permission to copy a share card to your clipboard, the six sites the button appears on, and our own API. Nothing else — not your other tabs, not your cookies, not your browsing history.
Nothing leaves until you click
There is no background scanning. When you press the button it sends the text of that one post, and that is all it sends.
Payments never pass through us
You send SOL from your own wallet straight to an address. FastCheck only reads the public blockchain to confirm it arrived, so it never holds your funds and never gets permission to move them.
Chrome lists every permission an extension asks for on its store page. Read ours before you install it — and read them on anything else you have installed while you are there.
Referrals
Get paid for the checks you post
Every verdict you share is a card with your own link on it. When someone signs up through that link and buys credits, you earn SOL — on every pack they ever buy, not just their first.

Free, and yours from the dashboard in one click. Your cards start

3
Earn on every pack
SOL lands in your wallet on its own, once you have cleared the minimal payout amount.
You buy a pack of checks
Nothing is capped per day, so a busy morning will not lock you out for the rest of it. There is no subscription and nothing renews by itself — when a pack runs out, you decide whether to buy another.
Priced in USD, paid in SOL or ETH at the rate quoted when you check out. One payment, no card stored, nothing recurring.
Where the price comes from
A check is not a database lookup. The model reads the post, works out what it is actually asserting, then searches the open web and X until it can settle it — several rounds of retrieval, not one query.
$0.044–$0.07
what one check costs us
Measured on real timeline posts, not estimated. The upper end is the research-heavy ones, where the model keeps searching.
$0.10
what one check costs you
Depending on the pack. The gap is the margin, and it is what pays for this thing to exist next month.
150
checks in the smallest pack
Twenty-nine dollars. Roughly what one bad trade costs an average trader — avoided 150 times.
You need the research. This is it, done in five seconds instead of five minutes, at a price you will forget you paid the first time it saves you from a bundle stacking on your head.
FastCheck does your own research.
