Question 1

How to upload a collection to IPFS?

Accepted Answer

We currently only handle collections of 24GB or less but you can still deploy a smart contract by uploading your collection to IPFS yourself. This 4 step guide will help you through the process.

Step 1 - Uploading the assets folder

You will need to create an account on one of the services below to upload your files to IPFS. Once your account is created, you will need to upload the assets folder.

Once uploaded, you should see an IPFS cid. Save this value somewhere since we will need in the next step.

nft.storage (free)
https://filebase.com/ (paid)

If you are using NFT Storage, considering their application NFT Up

Step 2 - Regenerate your metadata

Visit https://nft-generator.art/metadata, click "choose file" and find the file named metadata.json in your metadata folder. This should populate the collection name and description if you had one. In the "Image Url Prefix" text box, you will paste the following information: ipfs://REPLACE_WITH_CID_FROM_PREVIOUS_STEP/ (do not forget the ending /) and click "Generate". CID FROM PREVIOUS STEP

PASTE ON "Image Url Prefix"

Question 2

How much does it cost to deploy a smart contract on Ethereum/Polygon?

Accepted Answer

Our current contract, which is available on Ethereum and Polygon, utilizes the ERC721a standard. It includes the following features: Airdrop (with a maximum of 50 NFTs without a TeamPass), Whitelist, Reveal Later, and a built-in Minting Referral System.

Deploying the contract on Ethereum may incur gas fees of between 0.02 ETH and 0.04 ETH. On Polygon, gas fees are generally lower, and will not exceed $5.

Question 5

How to verify a smart contract?

Accepted Answer

First go to contract and click "verify":

When verifying a smart contract on Etherscan or Polygonscan, those are the options you need to specify:

On the next page we set optimisation to "yes"

Now we go to step 4 on our dashboard and find the smart contract source code:

We copy the contract source code and we paste it on ETH/Poly scan:

We now delete the constructor ABI displayed as an example on ETH/Poly scan:

And we copy our constructor ABI from step 4 under the smart contract source code:

Once all this has been done we can click verify and it will be done.

After verifying you can activate the proxy features of the contract to be able to interact with it: [Activate proxy features on a contract](/en/article/activate-pr

Question 6

How long does it take for my NFT to appear on Opensea?

Accepted Answer

There are two ways to import a collection to Opensea: by creating a smart contract or by manually uploading your images. When you deploy a smart contract, Opensea will automatically import the collection after the first NFT has been minted. As more NFTs are minted, they will gradually appear on Opensea.

If you see your NFT on Opensea but the image or name is not displayed, you may need to refresh the metadata. To do this, follow the instructions in this article: How to refresh the metadata on Opensea?
