Spark Opener
Spark Opener is the free browser extension that pairs with the Spark desktop app. It lets matching tokens open in a single, persistent terminal tab instead of piling up new ones.
What it gives you
- One tab, always. Your trading terminal stays in a single tab. Spark just swaps the token inside it.
- Instant switch. The new token appears in your terminal in tens of milliseconds - faster than any manual copy-paste.
- Zero manual work. No copying addresses, no hunting through feeds.
- Works with your account. You stay logged in to your terminal. The extension only opens tokens - it never signs transactions or touches your wallet.
Install
- Install Spark first. The extension is useless on its own - it needs Spark to feed it tokens.
- Add the extension from the Chrome Web Store. Works in any modern Chromium-based browser.
- Connect. Click the Spark Opener icon in your browser, hit Connect. Indicator should turn green.
- Enable Auto-Open in Spark. Settings → Application → Auto-Open = ON, Open Mode = current-tab. Matching tokens will start opening in your terminal.

Safety
Troubleshooting
- Indicator stays red after Connect - make sure the desktop Spark app is running. The extension talks to it on a local port.
- Nothing opens when a token matches - check Settings → Application → Auto-Open is enabled, and Open Mode is
current-tab. - Connection drops mid-session - hit Reconnect in the extension popup. If it persists, restart the desktop app.
