I was trying to test this code (https://github.com/ethereum-boilerplate/ethereum-nft-marketplace-boilerplate) and I followed the instructions to experiment the marketplace. However, when I create a new server and try to go to the page, I just get an “error: unauthorized”.
I copy the Application ID and the server URL into my code, and nothing happens.
Besides that, I don’t know where to find the smart contract address and the ABI.
Sorry, but I am kind of new to this and I am stuck with these problems.
Any help would be appreciated.
