simple web ui for viewing tokens

[yusefnapora]

It would be great to have a little web page that you could paste a token ID into and view the token asset and metadata.

This should be pretty simple to wire up using https://nfte.app, a react component that does some nice presentation if you give it info about an NFT. Since our contract won't be deployed on mainnet, we'll need to provide our own endpoint for the viewer to connect to, so this implies a minty serve command (or similar) that will host an endpoint to supply the data.

We'll also need a simple react app that has a text field for the token ID and updates the NFTE component on changes.
