How to put an nft on opensea

We’re developing a quick, cheap, self-serve marketplace creator that will bring some of the power and convenience of Stripe to the world of crypto.

Why We’re Excited

We feel confident in saying that OpenSea provides a valuable service to the space: we build a crisp, safe, open marketplace so that dapp developers can invest their time in creating mesmerizing, addictive, innovative projects. For the first time, developers can deploy a digital asset and instantaneously give users a liquid marketplace for their items. We like to think that we add a little extra flow to the rising tide that’s lifting the NFT ship.

Appendix A: Handling Common Issues

Sometimes, issues crop up that can’t be solved by reading the docs or the FAQ. And sometimes you just don’t have time for that nonsense. Anyway, here’s some information on diagnosing and fixing the most common issues, just in case:

I can’t access the storefront editor

By default, the storefront editor page (<CONTRACT_NAME/edit) is accessible to the contract’s Ownable owner. If your contract doesn’t implement Ownable, or if it does but the owner address is not accessible (maybe it’s living exclusively on a server), or if it’s just not working, we can fix that manually.

To compensate for the energy required to process these transactions, you have to pay a gas fee.

At the time of writing, the first transaction can cost anywhere from $70 to $300. The second transaction is usually $10 to $30.

This price range is due to the gas fees. There are days when the fees are higher, and then there are the slow days when the fees are lower.

You can track the prices on
Ideally, you want to hunt for days when numbers are below 100. This is when you want to initialize the account to save the most money.

Apart from the one-time upfront fees, OpenSea takes 2.5% of your sales. You only pay this tax after the item is sold.

How to Sell on OpenSea Without Paying Gas

If you’re familiar with Etherium blockchain, gas fees on OpenSea are similar to the transaction fees you already know.

NFT artists can fix the price or bid it against the highest suggested price. After selecting the sales method by clicking the “Post Your Listing” button, the Metamsk wallet will open and ask the NFT artist to make a transaction on the Ethereum network to put the NFT for sale.

At this stage, NFT artists have to pay the Ethereum network fee from the deposited amount of Ethreuem in the MetaMask wallet.


Creating an NFT is not a difficult procedure at all. If the NFT artist is not a celebrity (Paris Hilton or Jack Dorsey) or their NFTs do not have any special features, it is hard to convince people or find someone interested in purchasing that NFT.

It’ll take more than three minutes, but the results will be well worth it.

It all starts with creating an OpenSeaPort instance:

this.seaport = new OpenSeaPort(web3Provider, { networkName: Network.Main})

Once you got a seaport initialized, allowing your sellers to create listings is straightforward:

const expirationTime = ( / 1000 + 60 * 60 * 24)const auction = await seaport.createSellOrder({ tokenId, tokenAddress, accountAddress, startAmount, endAmount, expirationTime })

And allowing your buyers to snap them up is even easier:

const order = await seaport.api.getOrder({ side: OrderSide.Sell, … })const accountAddress = “0x…” // The buyer’s wallet addressawait this.props.seaport.fulfillOrder({ order, accountAddress })

If you’re comfortable with those code snippets, then you’ve got enough to get started.

When you transfer crypto to a different wallet or purchase an NFT on OpenSea, you should have enough ETH in your wallet to cover the initial transaction and the gas fees.

However, OpenSea recently introduced a new marketplace – Polygon, where you can sell NFTs without paying gas fees.

To create a Polygon collection, follow the steps below:

  1. Click on your profile picture and select My Collections.
  2. Click on Create a collection.
  3. Add the logo, banner, description, and set the royalties.
  4. You’ll be able to choose a blockchain for creating NFTs.

Select Polygon from the dropdown menu.

Now that you’ve created a Polygon collection, here’s how you can sell your NFTs.

Sell NFTs on Polygon

  1. Navigate to the NFT you want to sell and select Sell in the upper right-hand corner.
  2. Set the selling price, currency, and potential fees.
  3. Select Complete listing.
  4. Click on Sign and sign the transaction.

That’s it! You’ll see a message saying, “Your NFT is listed,” and you can copy its link wherever you like to boost the visibility.

How to Sell Domain on OpenSea?

One of the many categories of things you can sell on OpenSea is domain names.

You can also validate your metadata using a dedicated URL.

By default, the contract’s Ownable owner has access to the contract’s storefront editor page. When your wallet is using the owner’s address, you’ll be able to use the storefront editor without any additional efforts.

But don’t worry if your contract is noncompliant in either of these ways. We’ve got a playbook for that kind of thing and we’ll likely be able to set you up manually.

Check out the “Handling Common Issues” section below.

2. Get listed on OpenSea

To make OpenSea aware of your contract, go to our “get listed” page and follow the prompts. First, select the appropriate network. If your contract’s on mainnet, choose mainnet.

If it’s on Rinkeby, choose Rinkeby.

Create a Contract, Mint Tokens, and List Them for Sale, All in One Place

OpenSea’s Storefront Manager allows you to create a contract and an OpenSea Storefront, all without a single line of code. All you need is some content, a wallet, and a little bit of ETH to pay for gas. There’s no fee beyond what the Ethereum network charges.
Street artist Pascal Boyart used the Storefront manager to tokenize a mural.

The first one is to initialize your account for selling, and the other is to grant item access to OpenSea when a sale takes place.

  • After paying the fees, confirm the details and post the item on the marketplace.
  • Use the Activity tab on the left-hand side to view the NFTs you put up for sale.

    OpenSea – Cost to Sell

    As previously mentioned, OpenSea requires all first-time sellers to pay two fees before making the first sale. Note that the price for these two fees isn’t fixed, and if you know what you’re doing, you can lower them as much as possible. But how?

    First, the fees are paid in Ether. This means the price depends on the crypto’s value compared to a dollar or whatever your local currency is.

    Much like minting, the two fees are transactions on Ethereum’s blockchain.

    Because of this, they take processing power to complete.

    It can be listed on both markets simultaneously, so you have a higher chance of selling.

    Additional FAQ

    Do You Need a Wallet to Use OpenSea?

    Yes, you’re required to have a wallet to buy and sell on OpenSea. As you know, OpenSea is a tool for interacting with the blockchain. The company doesn’t own or store your NFTs. They simply allow peer-to-peer exchanges. Your use of the platform means you’ll interact with other blockchain users, so you need a wallet to turn the actions in the browser into blockchain transactions.

    Ready to Sell Your NFTs?

    OpenSea is an excellent place for selling NFTs. Whether you want to sell cryptokitties, cryptostickers, or other digital assets, you can do so here. But note that this can cost you a lot more if you’re not cautious.
