First CA Get the extension

How it works

Install, open X, read the line under the post. Nothing to sign up for, no wallet to connect.

1
Add it to Chrome

Download it from the install page and load it in Chrome in about a minute. It works in Chrome and in browsers built on it, like Brave and Edge.

2
Open any post on X

Already had X open? Reload that tab once. Under each post about a story, one line shows how many coins launched about it.

3
Read the line

Which coin launched first and how many seconds after the post, and how many coins used the same words in the past hour.

4
Tap it for the list

Every coin in launch order: copy number, age counting up live, market cap and volume in dollars, and why it is listed.

5
Copy or open a coin

Copy CA, or open the coin in Axiom, fomo, pump.fun or Solscan. Pick which one in Settings.

6
Choose where it shows

Only on posts with coins (default), on every post, or only when you tap. With "only when I tap", nothing is sent until you tap.

Why a coin is listed

A coin counts as a copy of the post when it links the post, carries the CA written in the post, shares two of the post's story words, or its ticker is one of the post's story words. Coins that share only one word are listed apart. Everyday words never count.

What first means

First means launched first on chain, nothing more. Coins launched before the post are listed apart and never counted as first. First CA shows facts and order, not advice.

How fast

A new coin reaches our server about a tenth of a second after it lands on chain, and a post on your screen is asked again every second or two while it is new, so a fresh coin shows within moments. The live numbers are on the home page.

The three hour window

Our server keeps every pump.fun coin from the last three hours. For an older post, the line says first is not known instead of guessing.

What is sent

The id and words of the posts on your screen, and any CA written in them. Never your account or anything else on X. Full details in the privacy policy.
