What You Should Know About Gas Fees When Selling An NFT On OpenSea

When selling an NFT, there are 4 scenarios in which you’ll pay gas.

  1. Wallet Approval to sell on OpenSea for the first time.

  2. Listing an item on OpenSea for the first time.

  3. When you lower the price or cancel a listing (more on how to avoid this in the article below)

  4. When you accept an offer from a buyer.

Below is an image from OpenSea that shows the two gas fees when you sell your first NFT on OpenSea.

How To Sell An NFT On OpenSea

The first step is to ensure you’ve got your MetaMask connected to OpenSea:

And then Sign the Transaction:

After you sign, you’ll end up at your account.

From here, choose the NFT you’d like to sell:

When selling, you can set a fixed price to sell at, start an eBay style auction, and even a dutch auction.

The most common sale is a fixed price set to expire at a certain date.

Setting A Time Limit Is Important

The maximum amount of time a listing is active is for 6 months, and you can make it shorter if you choose to.

Keep this in mind because if you need to change the price or cancel your listing before it expires, you’ll pay an Ethereum gas fee. These fees quickly add up if you need to change the price or cancel your listing a handful of times.

It’s better to set your listing for a short period of time and relist it again later vs having to cancel the listing 4 months later and pay a gas fee:

Some people prefer the set and forget method with an expiration date far into the future. Others like to play a little more hands-on and change the price more frequently with an expiration date of a week, day, or even just a few hours.

The short expiration date play is especially useful when the market is seeing a lot of action and the Floor Price fluctuates many times a day.

Consider the market conditions and your personal trading style when setting the expiration date.

Finding The Market Price To Sell An NFT On OpenSea

Some NFTs are rare, making them worth more so you’ll want to check your NFTs rarity.

Another way to check your NFT’s market value is using OpenSea’s filters to see what similar NFTs are selling for.

You don’t want to accidentally sell your NFT for a big discount because there are always people looking for a steal. Make sure you’ve done your research on your NFT’s market value before listing it for sale.

Once you’re confident in the market value of the NFT you own, type in the price you want to sell your NFT for, and ensure you get the decimal point correct.

Selling an NFT worth 0.08 for .008 is a mistake you do not want to make. You can see the dollar amount of your NFT under the Price in ETH

You’ll see a fee is taken out by OpenSea for providing the platform, and Creator Royalties will be different for every project.

Once you’ve selected your time period and price, sign the transaction for free and cross your fingers for a buyer to come along and scoop it up!

Email Notifications On OpenSea

Once signed, you can turn on email notifications to get an alert of any activity on your listing. This includes offers from buyers.

Email notifications are good because MetaMask won’t send you a notification if your item sells:

Receiving Offers On Your NFT In OpenSea

You can receive offers on any NFT you own, not just the items you’ve listed for sale.

These offers, if accepted, will be paid out in Wrapped Ethereum. Wrapped Ethereum has the exact same value as Ethereum. You’ll notice most offers are for less money than the NFT is actually worth. There are almost always buyers looking to strike a deal. You can create a Counter Offer to raise the price if you’d like. As a seller, you’ll pay the gas fee when accepting an offer, paid out in ETH.

If you want to Swap your Wrapped ETH back to Ethereum, you’ll pay a gas fee in ETH. It’s always a good idea to leave a few hundred dollars in Ethereum to pay for gas fees. I understand that’s a lot of money to spend on fees. There are emerging marketplaces that allow little to no fees when buying & selling.

Creating An Auction On OpenSea

Creating Auction On OpenSea


If your NFT is a unique, serialized NFT (most profile picture projects are), you can hold a timed auction, similar to a sale on eBay.

You’ve got a few options at your fingertips:


Sell to the highest bidder - Bidders drive the price up and the item goes to the highest bidder at the time limit.

Sell with declining price - This allows you to create a dutch auction where the price starts high and decreases to a certain price at a specified time.

Duration - Set your auction to end at a certain time. You can choose any amount of time up to 6 months from now.

Reserve Price - If your auction doesn’t hit this price, it doesn’t sell. You don’t have to set a reserve price, but it’s often a good precaution to ensure you don’t sell for too cheap. Many sellers do this to test the market and see what price their NFT will get. Bidders will see that there is a Reserve Price but they won’t get to see what the price is until it’s reached.

The buyer will pay the gas fee when the item sells. It’s totally free to list an item for sale. You’ll only pay the OpenSea & Creator fees when the item sells.

The buyer will pay the Ethereum gas fee when they buy.

Setting A Private Listing In OpenSea

A private listing is useful for ensuring only a certain person can buy the item. This is great for peer-to-peer deals where you’re offering a certain price and want to ensure a specific person can buy it. All you’ll need is their Ethereum address.
