How it works

Three moves. Then you are the Big Brother.

  1. 01

    Install the Eye

    Add Big Brother from the Chrome Web Store. It stays out of the way until you open a token.

  2. 02

    Open any token

    GMGN, Axiom, FOMO, Pump.fun Terminal, or Dexscreener. The floating Eye appears on the page — same controls as the popup.

  3. 03

    Trade from the levels

    Two dashed lines: where whales and market makers bought, and where they sold. Ranges and filters live in the Eye. The rest is in the extension docs.

Holders

Who still holds the bag.

Balance-weighted average. A wallet still sitting on a lot of tokens moves the line more than one that already dumped. Burn, LP, and anything you blacklist are always out.

Traders

Who actually traded it well.

Equal-weight average of the most profitable wallets. Bag size does not count — you are looking at how they bought and sold, not what they still hold.

Get the Eye

Now you are the Big Brother.

Install is free. Chart lines need a paid subscription, paid in crypto. Settings and blacklist work before you pay. Paste your GMGN API key in the Eye.
