  Shady... new HN user. No contact / author info on the site. Alleged references to ethereum in the source code.

  Any recent browser exploits involving WASM and webcam apis?

    I may have missed something obvious, but I can't find the references to ethereum in the source code. Can you point me to the js file?

    I have found this though: https://github.com/vercel/next.js/discussions/44899

    It may be unrelated to the app which is using Vercel next.js and it seems to catch the error when in dev mode (yes .. I don't know much about it). Brave uses a wallet (Brave Wallet) and it looks like it is adding this every time you visit a site. Newer versions of Brave shouldn't display this error (or when browsing in private mode). I am confused, because I am discovering this right now. Sorry.

    https://github.com/localtunnel/localtunnel/issues/514

    Anyways, if app author is reading, there may be a simple solution by adding this code:

      window.addEventListener('error', e => {
        if (e.message?.includes('ethereum')) e.stopImmediatePropagation();
      });

    OP is one hour old here, what could go wrong?

    but let's be optimistic (since it's a known Brave bug): does it happen to you when using private mode or another browser?

    I would rather you have typed this on a typewriter. They're not that expensive.
