Is there a tool to verify that the metadata of my NFT is correct?

Question

I am creating a collection of NFTs and I want to test that the metadata and the media files are correct. I am setting tokenURI on chain. How can I do this? I am using Polygon Mumbai.

Answer 1

If your NFT collection contract follows the [IERC721 interface][1], when you mint or transfer, OpenSea will listen to the events and show the collection on the OpenSea testnet, your collection can be found at: https://testnets.opensea.io/assets/mumbai/YOUR_CONTRACT_ADDRESS. You can then check if the NFT is displayed correctly.

Hope it helps
