Fill Monitor

What is Fill Monitor?

Fill Monitor automatically sends browser notifications when your Polymarket orders are filled. Once enabled, it runs silently in the background - no need to keep this page open.

How to Enable

  1. Connect your wallet - Click “Connect Wallet” in the navigation bar and connect your Polygon wallet
  2. Sign the message - You'll be prompted to sign a message to authenticate (one-time setup)
  3. Enable notifications - Allow browser notifications when prompted
  4. That's it! - The monitor will automatically start and continue running in the background

Important Notes

•

External wallet required: This feature only works when using Polymarket with an external wallet (like MetaMask, Rainbow, etc.). It does not work with Polymarket's built-in wallet.

•

Polygon network: Your wallet must be on the Polygon network. The monitor will prompt you to switch if needed.

•

Browser notifications: Make sure notifications are enabled in your browser settings.

•

Automatic reconnection: If the connection drops, the monitor will automatically reconnect.

•

No re-signing needed: After the initial setup, credentials are stored locally and you won't need to sign again.

Privacy & Security

Your API credentials are stored locally in your browser and never sent to any third-party servers. The fill monitor connects directly to Polymarket's official WebSocket API using your authenticated credentials.

To disable: Simply disconnect your wallet and clear your browser's local storage for this site.
