8. Testing your contract on testnet
You deployed your NFT smart contracts. Now try minting and viewing them on testnet.
Try to mint a test nft from your collection. If the button is hidden, most likely minting
start_timehas not passed so the contract does now allow any minting yet. Try launching another collection with the same metadata and images, but change the
start_timeto a few minutes from now so you can test out minting.
Now that you have minted, try visiting your profile page to see if the freshly minted NFT shows up. If the image is broken, double check the ipfs link in your metadata, it is likely not formatted correctly. If your NFT does not show up at all, your ipfs link to your token metadata is probably broken or not formatted correctly.
The last step is to click on the token and view token details. It should show your collection's token image with attributes. If the attributes are not displaying, your metadata json attributes are probably not formatted correctly.
If your collection passes all of these steps, you are ready to launch on launchpad or externally on your own website.
