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 - Converting the assets folder

This step can be skipped if you are using Pinata or Dreamlink.

When you download your collection as a zip file, you will extract an assets folder and a metadata folder. Now, we need to convert all the files from the assets to a car (content addressed archive).

Visit https://car.ipfs.io/, click on "Open File PIcker" and select ALL the files in the assets folder. Now scroll down the page and click "Download".

Step 2 - Uploading the assets folder

You will need to create an account on one of the following services to upload your files to IPFS. Feel free to choose another one if preferred. Follow the signup steps and upload the car file generated in the previous step.

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

Step 3 - Regenerate your metadata

Visit https://nft-generator.art/metadata, click "choose file" and find the file named

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

Accepted Answer

Our current contract (ETHEREUM/Polygon) uses ERC721a standard, the contract has the following functions: Airdrop (50 max without TeamPass), Whitelist, Reveal Later and a built in Minting Referral Sytem

To deploy on Ethereum, gas fees will be between 0.02ETH and 0.04ETH, on Polygon gas fees are cheaper so gas fees won´t 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-proxy-fea

Question 6

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

Accepted Answer

You can import a collection by creating a smart contract or manually uploading your images to Opensea. When deploying a smart contract, Opensea will automatically import the collection after one NFT is minted. As more NFTs are minted, they will gradually appear in Opensea.

If you see your NFT on Opensea but you do not see the image or the NFT name, click the "Refresh Metadata" button.
