Zyper Capture extension

Capture explorer and mint-site calls in Chrome or Edge and open them in Zyper AIO.

Zyper Capture is an unpacked Chrome/Edge extension that sends captured transaction details to the desktop through the zyper-v1:// custom protocol.

Install

  1. Open Settings > Zyper Capture Browser Extension.
  2. Download zyper-capture.zip from license.zyper.app.
  3. Unzip it somewhere stable.
  4. Open chrome://extensions or edge://extensions.
  5. Enable Developer mode.
  6. Click Load Unpacked and select the unzipped extension folder.

Launch Zyper AIO once before using the extension so Windows registers the zyper-v1:// protocol handler.

What It Captures

Capture typeWhat gets sent to Zyper
Hex captureto, raw calldata, native value, source URL
Function capturecontract, function name, function signature, visible args, native value

Hex captures open the Build Task dialog in hex mode. Function captures open in ABI mode with a synthesized ABI for the captured function, so you can edit or fill missing args before saving rows.

The extension intentionally does not set max fee or priority fee. The desktop starts gas fields from your normal defaults or auto values to avoid unit mistakes.

Clicking a capture button opens a zyper-v1://quicktasks?... URL. If Zyper is already running, the new URL is handed to the open window and the Tasks dialog opens. If it is not running, Windows launches the app and the app consumes the pending URL on startup.

Privacy and Safety

  • The extension does not sign transactions.
  • It does not bypass wallet approvals.
  • It stores the latest capture locally in browser extension storage.
  • It talks to the desktop only through the zyper-v1:// URL.
  • It does not make remote API calls from the extension background script.

The extension ZIP download is separate from the desktop auto-update flow.

Troubleshooting

Open in Zyper does nothing. Launch zyper-aio.exe once manually so it registers the protocol handler, then try again.

The dialog opens but some args are empty. The extension can only scrape fields visible on the page. Fill missing parameters in the Build Task dialog before saving.

Gas fields are blank or auto. That is expected. Gas is owned by the desktop task config, not the extension capture.
