The SlabTracked extension for Chrome

Step 1

Download & extract

Download the zip and unpack it to a folder you can keep around.

Step 2

Open extensions

In Chrome, navigate to chrome://extensions.

Step 3

Enable Developer Mode

Flip the toggle in the top-right of the extensions page.

Step 4

Load unpacked

Click "Load unpacked" and select the folder you extracted.

Step 5

Sign in

Click the SlabTracked icon in your toolbar and sign in.

Step 6

Save credentials

Open Settings and add your CGC and PSA logins.

CGC / PSA Sync

Real-time submission status, certs, and order history.

FedEx & UPS Tracking

Tracking numbers picked up automatically.

Auto-Login

Skip the password dance — extension keeps your session warm.

eBay Drafts

One-click drafts pre-filled from cert data.

Whatnot CSV

Build show-ready inventory exports.

Cert Photos

Front/back captures attached to every cert.

Telegram & Discord

Status changes pushed to your channels.

Cert Lookup

Lookup by cert # without leaving the page.

Description Fill

Auto-populate listing descriptions from templates.

Listing Templates

Reusable templates for fast bulk listing.

Fast Sync

Incremental sync runs in the background every 30 minutes.

PSA Relay

Turn your browser into a PSA search relay node.

Completed PSA orders stay completed

Historical completed orders no longer reopen PSA detail tabs during scheduled syncs, and return-shipping metadata can no longer downgrade Completed back to Shipped.

CGC CSV reconciliation repaired

Invoices and cert slots present in the CGC CSV are preserved even when certificate enrichment is incomplete; missing grades are no longer mistaken for rejects.

CGC-friendly adaptive throttling

Cert lookups share a conservative request queue, stop immediately on CGC limits, rest between small batches, and automatically resume from a saved checkpoint.

Your PSA session token stays in your browser

The extension no longer uploads your PSA access token to the SlabTracked server - server-side autofill goes through the relay bridge instead, so the token never leaves your machine.

Relay operations authenticated end-to-end

Every relay register/unregister call now carries your SlabTracked sign-in, and the server rejects anything unauthenticated.

Locked to slabtracked.com

API endpoints are pinned to an allow-list, external messages are sender-verified, and debug backdoors plus the direct Telegram/Discord send path (and those host permissions) were removed - alerts now route through SlabTracked.

Autofill asks first (v2.7.2)

Wizards only auto-run within 10 minutes of a kick from the web app - any other visit to a form shows a "Start autofill?" prompt, and your answer sticks for the tab.

Pause Extension is a true kill switch (v2.7.2)

Flipping the toggle instantly stops every open wizard page, cancels running fill loops and countdowns, and blocks new automation jobs.
