NFT Gateway POC

This webapp is meant to demonstrate how possession of an NFT can be used to grant access to a part of a website.

The web3.js library is used to get the user's ethereum address, and they are asked to sign a message to verify their ownership.

A request with the signed message is sent to the API which checks the balance of the wallet before issuing an access token to the client.

Building Locally

Setting up

If you do no have node.js installed, get it on their site.

You will need an RPC URL for the backend to access the ethereum network. You can get free access at Infura. Your link will look like this:

https://mainnet.infura.io/v3/YOUR_API_KEY_HERE

You will need to use this to replace the dummy link in backend/index.js.

npm install
