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 (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-pr

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.
