What Is OpenSea

OpenSea is the largest NFT marketplace available today, gathering millions of active users daily. It is also the leading NFT marketplace in terms of daily NFT sales.

It was a revolutionary tool in the world of digital assets. Since 2017, Devin Finzer and Alex Atallah have been working to deliver the best experience for people trading or selling NFTs.

It is the favorite place for some of the most famous NFT collectors and artists looking for a place to sell their assets. But this is not the only thing that makes OpenSea one of the most hyped NFT marketplaces available.

There are tons of other NFT marketplaces being created every day, but still, artists and investors prefer to sell NFTs on OpenSea instead of any other. We will show you some of the reasons why OpenSea is still the best place to mint, buy, or trade NFTs.

What Blockchain Does OpenSea Use

Although the main blockchain OpenSea users choose is Ethereum, the platform allows the usage of different blockchains. When buying NFTs or doing any operation, OpenSea allows you to choose which blockchain you want to use.

This freedom, along with the fact that OpenSea supports multiple chains and over a dozen wallets, is one of the reasons why many people prefer the platform when trading NFTs. Most marketplaces only allow users to choose Ethereum, and its high gas fees can be a deal breaker for many collectors and artists.

The main blockchains you can use when making operations with NFTs on OpenSea are:

  • Ethereum
  • Polygon Blockchain
  • Klaytn
  • Solana
  • Arbitrum
  • Optimism
  • Avalanche
  • BNB

Here are some of the things that you can do in OpenSea:

One of the reasons why OpenSea has emerged as the leading platform for selling NFTs is its seamless integration with social media accounts. This feature enables users to effortlessly promote their NFT collections and share links directly from the platform, thereby amplifying their reach and engagement.

OpenSea Analytics

Another detail that makes OpenSea one of the most complete NFT markets is the analytics feature on the website. It allows creators and investors to check out the most sought-after collections and what is the best course of action to take when investing in.

The tab shows you all the essential data regarding each collection, including floor price, sales volume, and the number of trades.

The marketplace data is accessible to everyone. 

Auction Settings

Another incredible feature that OpenSea offers is the number of possibilities for auctioning NFTs. From simple auctions to Dutch auction listings, you can choose the format that fits your needs most, like active English auctions, for example.

This makes it way more accessible, not just when selling but also when buying NFTs. You can sort the auctions by format and participate in those that meet your expectations.

It is vital to notice that each auction model will have its own OpenSea fees. Make sure to only participate in processes that you understand and be careful with the starting price that you put in your asset.

Low Fees

Another great reason to use OpenSea instead of custom marketplaces or any other option is its low fees. Whether when doing Dutch auctions or any other transaction, you will pay a single fee.

The OpenSea fee has a fixed price of 2.5% regardless of the asset type. It is extremely low, especially compared to other NFT marketplace platforms, like SuperRare or Mintable.

Notice that this fee regards only the OpenSea percentage. The final value might drastically change depending on which blockchain you work with.

NFT Auction Type Variety

One of the most remarkable OpenSea pros is the fact that it allows users to upload a massive variety of digital items and in numerous types of auction. From Dutch auctions to more traditional options, there are numerous options for what and how you sell on OpenSea.

If you search for a non-fungible token marketplace that is complete and allows you to auction your assets in the best way possible for your needs, OpenSea is for you. Its interface and bid options menu also make it possible for you to quickly filter your preferences. So you don’t have to stick to a single type of auction when using the platform.

You will find two main auction types when using Opensea:

  • English Auction – Sells the asset to the highest bidder
  • Dutch Auction – Starts at maximum price and declines until someone makes the first bid

Sending Gifts

Another excellent tool for promotion is the gift-sending function available on OpenSea. The platform allows you to send any NFT as a gift to other users at no extra cost, just like gas-free transactions.

It is important to know that gift sending and receiving are not restricted only to the platform itself. OpenSea also allows you to make this kind of transaction even if the user is from another platform.

The gift function is only available in the Ethereum blockchain. If you create custom marketplaces or use another famous platform, you can only do this if your wallet supports ETH.

Wallet Variety

When using OpenSea, you will never have to worry about wallet compatibility. It is likely that the platform allows you to use your preferred digital wallet since it has support for 15 different wallets.

The process is very straightforward and can quickly be done when setting up your OpenSea account or after, if you prefer. Here is a list of wallets supported by the OpenSea team:

  • MetaMask
  • Coinbase
  • Trust Wallet

  • Dapper

Here are some examples that were uploaded to OpenSea and became iconic NFT collections:

Bored Ape Yacht Club

Even if you’re a beginner in the NFT world, you’ve definitely heard about Bored Ape Yacht Club (or BAYC). It was the most successful collection ever created and became a martyr in the world of digital art.

The project was uploaded to OpenSea and quickly became the most profitable collection on the platform. Some pieces are sought-after today, with prices of more than dozens of thousands of dollars.


If we had to tell a collection that can rival BAYC in terms of success and profitability, it would be Cryptopunks. The project was also uploaded to OpenSea and featured 10,000 unique digital assets.

Its success was similar to BAYC, with prices quickly skyrocketing and tons of investors competing to see who could grab one of the non-fungible tokens. Cryptopunks are still worth tons of money nowadays.


Another highlight of OpenSea work portfolio is the Doodles NFT project. Featuring a visually pleasing art style, the collection became an investor’s favorite, mainly thanks to the high trade volumes regarding the pieces.

It is also an extremely valuable collection, with some pieces being more expensive than a house. The project is still in the top 10 ranked collections of OpenSea, being a reference for many artists that want to enter the digital art world.

Time to Create Your Account on OpenSea

Now that you know what OpenSea is and why it is currently the largest NFT marketplace, it is time to start setting up your account on the platform. Follow each step carefully to avoid problems with your digital pieces or coins. 

This way, you avoid problems with your crypto wallet and keep your account secure, guaranteeing you won’t lose any money or NFT.
