Hi can you look at the repo code linked above to see if youâve missed anything. What have you done in code when you say replace the nft?
Well the sample is working perfect. When I made a nft that is mintable on opensea and I replaced the 1 in turtorial with the 1 I made it wont work.
Also what adress needs to be in this field i dont get it? I tried the same adress in the laucher and the adress that deployed the contract. Still no luck
What do you mean it wonât work? Do you get any errors?
MUG_CONTRACT_ADDRESS needs to be a contract address, in this case on the Mumbai network based on MUG_CHAIN. Which network is your NFT contract on (the one in the top photo)?
The Mug contract adress = 
I made it on open sea on the matic mumbai network. So i put this adress both in the editor field and as the The Mug contract adress?
Yes, if youâre simply just swapping out the sample contract (which comes with the tutorial I assume) with your own.

Well I Made new nft on Opensea on mumbai. I changed the. MUG_CONTRACT_ADDRESS = to the owner of the collecttion. Then i added the token info to the claimNft. Transaction succes but i dont get the nft⌠I think the contract that is deployed from opensea is not see same as the 1 used in the tutorial. Think thats the problem. Think it has to do with the ABI and the Claim function. Can we have some insigth where and how the contract was made?
MUG_CONTRACT_ADDRESS = to the owner of the collecttion
No the address should be the contract address, not the owner or creator of that contract.
I think the contract that is deployed from opensea is not see same as the 1 used in the tutorial.
Isnât this your own contract? I thought this was what you were trying to do, use your own instead of the tutorialâs contract. Where has it come from?
Oke, I changed the MUG_CONTRACT_ADDRESS = to my own contract address that is on opensea.
I also changed the adress and token id in the editor ClaimNFtcontroller. Now i get Transaction error Internal Json-rpc error.
Make sure your MetaMask is on the right network. Is your contract more or less equivalent to the tutorial contract? E.g. same function youâre calling, same network, check all these details. Also if you made your NFT directly on OpenSea, I donât think this will work.
Thank you glad! My whole point was will it work if I made the nft directly on opensea⌠My English is bad so kind of hard to explain. You got any tutorials or a sample contract that i can use as refferance?
Yes I should have clarified that earlier, I was under the assumption that you had created your own contract that was then listed on OpenSea since you were swapping it out.
Possibly the source code of the contract is available, Iâm not finding it in the repo however. Can you post the sample contract address? I donât know enough about this tutorial/project to see if thereâs a similar base contract you could use.
Here is link to the nft thats is used in the tutorial
nft url
contractadress: 0x698d7D745B7F5d8EF4fdB59CeB660050b3599AC3
Tokenid : 0x698d7D745B7F5d8EF4fdB59CeB660050b3599AC3
thanks you saved me so many headaches. i tried this without the json edit on my desktop and my goodness so many errors. i did this on my laptop and works perfectly.

Glad I helped 
Hello, I am trying to implement the ClaimNFTcontroller.cs in my own project. I imported all the files from the Web3SpaceShooters directly, however I still get this compile error:
Assets\MoralisWeb3ApiSdk\Moralis\ClaimNftController.cs(138,54): error CS0117: âMoralisInterfaceâ does not contain a definition for âSendEvmTransactionAsyncâ
I did not change any code in the C# file, and the file has no errors in the demo project. What is going on here?

Hi @ardawarcraft and first of all, welcome to the Moralis Unity community
What version of the Moralis SDK do you have installed in your own project?
Thanks!
Hi, thank you
I do not know what version because I directly copied the MoralisWeb3ApiSdk folder fully from the Demo project to My project. I think the specific github directory is this, https://github.com/MoralisWeb3/youtube-tutorials/releases/tag/v1.0.0-unity-web3-spaceFPS , whatever version is used here I use the same because I copy pasted it from there anyway
Hi @ardawarcraft!
Is there any other MoralisInterface function getting the same definition error or just SendEvmTransactionAsync?
Thanks!
Hi @dpradell actually yes there is 1 more. ''Assets_Project\Scripts\Moralis\MoralisWeb3Manager.cs(153,30): error CS0117: âMoralisInterfaceâ does not contain a definition for 'InsertContractInstance"
and the other, as you mentioned correctly, is
âAssets_Project\Scripts\Moralis\ClaimNftController.cs(138,54): error CS0117: âMoralisInterfaceâ does not contain a definition for âSendEvmTransactionAsyncââ
