PaperApe Extension

Paper trade Solana tokens directly on supported trading platforms

Chrome MV3 Extension

Paper trading without leaving the chart.

The extension brings the PaperApe simulator to BullX, Axiom, Padre, Photon, and GMGN. It uses your PaperApe account, proxies API calls through the background worker, and keeps all trades simulated.

Trade On The Terminal You Already Use

PaperApe detects supported Solana token pages and mounts a draggable paper-trading widget over the host platform.

Entry And Exit Fills

Buys, sells, and sell-init fills are saved with token price and market cap so your simulator history stays tied to the chart.

Isolated Widget

The extension renders inside Shadow DOM, keeping PaperApe styles separate from BullX, Axiom, Padre, Photon, and GMGN.

Install GuideUnpacked build

Build the extension

Run npm run build from the repo root. The Chrome-ready extension is emitted to apps/extension/dist.

Open Chrome extensions

Go to chrome://extensions and enable Developer mode.

Load unpacked

Choose Load unpacked, then select the apps/extension/dist folder.

Open PaperApe in the same browser and sign in. The web app syncs your auth token to the extension bridge.

Open a token page

Visit BullX, Axiom, Padre, Photon, or GMGN. PaperApe appears when it detects a Solana token address.

What It Does

Detects token addresses, shows live token data, executes simulated buys/sells, updates PaperApe positions, and draws fill markers when the host chart allows it.

What It Never Does

It never sends real transactions, never controls your trading wallet, and never trades with real funds. PaperApe stays educational and simulated.
