Challenge 0, side quest suggest to try opensea testnet that is not an option anymore

[luucamay]

Hi, I suggest to remove or clarify that the side quest "Want to see your new NFTs on Opensea? Head to Testnets Opensea", will not be possible because 2 weeks ago OpenSea stopped the support for testnets :/

Thanks @luucamay for creating the issue!!

Maybe we could use etherscan

https://sepolia.etherscan.io/nft/0x17ed03686653917efa2194a5252c5f0a4f3dc49c/2

It's not rendering the image, not sure if it's something to do with our metadata or etherscan problem

I think we need to use live network like Optimism. Tried it, deploying and verifying costs ~0.000002 Eth = ~0.01$. Minting fee is 0.000000033409195296 ETH = 0.000144$. So we can configure 0.05$ faucet or even give the same amount of Op Eth directly from tg chats. And then use OpenSea again https://opensea.io/item/optimism/0x527b27cD8DdA5fB91945b34fD2e53E44F7F64A52/1

requirements:

• faucet or other mechanism to give user some eth
• we need to allow not only testnets on grader

I tried to find nft marketplaces working with testnets, but no luck. Rarible has a testnet https://testnet.rarible.com/ and you even can search for some "YourCollectible" nfts, but I tested it with new contract/mint and it doesn't index it

Maybe we could use etherscan

As I understand testnets etherscan doesn't show images. I don't have official data, only stackexchange link. Also checked some collections, all have no images

Other options:

1. Use metamask

But it requires to enable nft related options:

It's not good, so I'd avoid it

2. Just remove the section. Also, don't like it because it's very important to see that you created something that works
