Can somebody tell me how to do it or send me a guide?
on what part do you need help?
for smart contract deploy: https://www.youtube.com/watch?v=roHoOZXIxYs&ab_channel=MoralisWeb3
then you should only need to create a new Moralis Server for testnet, change the contract address in your code, use that testnet in your metamask
thanks for the help. idk why but i did the tutorial from 2 years ago and that didn’t work. The new one is great!
