AR guitar with just a laptop and scissors

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.

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();
  });

ps: when I visited the site, I intuitively said no to myself "no way I am activating my camera in order to try air guitar, I cannot trust what I am viewing". The vibe feel, the lack of vids, the overall "quickly setup site" made me go.

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.
