Wonderland @Goerli testnet

Storyline:
The Web3 journey of Disney continues with the launch of its brand new NFT collection, Wonderland, on the Goerli testnet. For NFT and Disney fans, Wonderland is an NFT marketplace where you can mint, buy, sell, and discover exclusive Disney NFT drops. Wonderland NFT holders will be able to experience special perks and discounts at the partnered Disneyland parks.

Functionality

• Mint, Approve, List: Access will be granted to whitelisted members to free mint, approve, and list the NFT on the Wonderland marketplace. There is only a minimal transaction fee to pay. Take note that everyone is considered a whitelist member during the current development phase. The listing price of the NFT must be specified at the listing stage.
• Update: The price of the listed NFT can be updated on the profile page under the section of Your Listed NFTs.
• Buy: Anyone who wants to become a Wonderland NFT holder can buy the NFT on the market page.

Things to take note

• NFT image on the market page will not show up if Metamask account is not connected. Image of gradient background will appear instead of the actual NFT image.
• If your Metamask account was connected but you still get gradient background display as NFT on the market page, please be patient and wait for a moment.
• Take note that the image on mint page might take time to load.

What if you encountered the following page loading error?

ipfs resolve -r /ipfs/bafybeifocupu3e5ts4dosecxmsqbrwtkbjcenvmkkvz7dvou5vlk6jr5o4/Profile: no link named "Profile" under bafybeifocupu3e5ts4dosecxmsqbrwtkbjcenvmkkvz7dvou5vlk6jr5o4

For example, you are now on the profile page and wish to reload the page. You might encounter the error as stated above. When you try to press the reload button, the same error appear.

How to solve this problem??

You should now have this address wonderland.on.fleek.co/Profile on your browser's address bar. Remove /Profile from the address bar and reload the page. The problem might be resolved.
