QUESTION

How to pull out a portion from long string of metadata

Asked 2022-Mar-23 at 07:19

This is my first time working with very long metadata in an api response. I would like to dig into the metadata and only pull out the image_url. I am wondering if there is an easier way to do so than splicing this extremely long string a bunch of times. In this example here is the metadata:

You can use JSON.parse() on the metadata string to get a JavaScript object. From that you can just index the object with the image_url key.

QUESTION

How to do a secure login with web3 (Metamask)?

Asked 2022-Mar-04 at 20:04

So, I want to do a webpage, where you have to log in with metamask, only.

I've seen that cryptokitties.co did a really good job, not even prompting for a password.

The only thing they require is a signature from you. But here is the thing I don't understand: What do you sign, that you are protected from a signature replay? Or are they protected from a signature replay in the first place?

What I thought about so far (but it didn't work):

Using a nonce -> What happens if the client wipes localhost?
Using time -> There are different timezones and taking UTC -> One can send the two requests almost instantly one after another.

However, if I invalidate the signed hash of the time on the server side and don't accept a second attempt, would this be a good practice?

You can try:

Client sign a nonce
Check with his public key that it is him and return a token (JWT) with encrypted information (expiration date, public key, etc)
The user is already authenticated.

I think it can work, but possibly there is a better way.

These systems are zero knowledge
