The watcher

#What it does

X Money has no API, so the only reliable record of a payment is your own X Money activity. The xnft Watcher is a Chrome extension that reads that activity while you’re signed in to x.com and reports each transaction to xnft.money, signed with a key that only your browser holds.

#Install

You need Chrome 120 or newer. During the private beta we send invited creators the extension as a folder; install it from chrome://extensions → turn on Developer mode → Load unpacked → pick the folder.

#Pair it

1. Get a pairing code

   In Studio → Watchers press Get a pairing code. You get an 8-character code (like K7QM-2XHD), valid for 10 minutes and usable once.

2. Enter it in the extension

   Open the extension, check the server address (it’s filled in for you), enter the code and press Pair. Chrome may ask permission to reach the site — allow it.

3. Check it’s healthy

   Within a few seconds the Watchers tab shows the device as Healthy and your checkout turns live (if nothing else is missing).

You can pair more than one watcher. A second one makes large payments confirm faster, because two devices agreeing is extra proof.

#Keep it running

• Keep Chrome open with an x.com tab signed in to your X account, with X Money open.
• Don’t let the computer sleep while your drop is live.
• The watcher sends a heartbeat every 30 seconds. If none arrives for 90 seconds, your checkout pauses by itself and resumes when it’s back.
• Payments made while it was offline are picked up once the X Money activity page shows them again.

#Status

#What it sees and sends

• It reads only the X Money activity of the account it is paired to. Before reading anything it checks which account the x.com tab is signed in to — the handle in the account menu and the account ID in x.com’s twid cookie — and reads nothing if it isn’t yours.
• For each transaction it sends: the transaction ID, direction (in or out), the other party’s handle, the amount, the note and the time.
• It never sends your cookies, password or anything from other pages. The only thing it takes from a cookie is your numeric X account ID.
• Payments that have nothing to do with xnft.money are reduced to an ID and amount after a day.
• Each report is signed and can’t be replayed; up to 5,000 reports per hour are accepted per seller.
