I can't add my item from my wallet to sell
IF you get an error when trying to sell an item from your wallet check here
When you list an item for sale from your wallet, we have to scan the smart contract and make sure it will work on our marketplace.
If you see a message that says:
"invalid smart contract" or "not a valid smart contract": you are using an address that DOESN'T belong to a smart contract.
This item cannot be resold: The creator of this item doesn't want people to sell it.
Token ID doesn't exist: You entered a wrong token ID that doesn't exist on the smart contract.
​You can always contact support if you need mo​re help​
