OpenSea – A Quick Review

The NFT industry has changed dramatically over the past few years and OpenSea is right at the center of this market. Launched in 2017, OpenSea has positioned itself as the first and largest marketplace for non-fungible tokens.

The platform is designed in a way to help even beginners familiarize themselves with the world of NFTs, and make investments into digital assets easily and effortlessly.


The future of the NFT industry is here, with OpenSea emerging as one of the best NFT apps that will be making waves in 2022.

Today, OpenSea has over one million users across the world. This NFT marketplace saw its trading volumes hit an all-time high of nearly $5 billion in early 2022.

According to recent statistics released by the platform, you can use OpenSea to access over 700 NFT projects which translate into more than 80 million unique non-fungible tokens.

OpenSea provides the following functionalities to its users:

  • Buy and sell NFTs across a variety of types and collections
  • Create your own NFT collections
  • Transfer NFTs to a private wallet
  • Send NFTs as a gift to other OpenSea users

This NFT marketplace also features exclusive drops of non-fungible tokens. In other words, if you are looking for the next best investment opportunity in the NFT space, OpenSea is a platform to watch.

Cryptoassets are a highly volatile unregulated investment product. No UK or EU investor protection.

OpenSea Supported Blockchains

OpenSea started as an Ethereum-only NFT platform. However, over the years, it has added compatibility with other prominent blockchains. At the time of writing, it offers cross-chain support across Ethereum, Polygon, Klatyn, and Solana.

OpenSea blockchains

On top of this, OpenSea has created a gas-free marketplace hosted on the Polygon blockchain. Whether you are looking to buy, sell, or transfer NFTs, you can do so without having to pay any gas fees on OpenSea’s Polygon platform.

Solana and Klatyn also let you access these services at relatively low gas fees when compared to that of Ethereum.

OpenSea Features

While OpenSea has a first-mover advantage in the NFT market, that isn’t the only aspect that promotes the growth of this platform. OpenSea has also upgraded its features, adding more NFT collections and functionalities that make it attractive to users.

Below, we take a closer look at the different features of OpenSea.

Wide Range of NFTs

If you are new to the NFT world, it is important to know that there are different types of NFTs available. These range from artworks, music, photography, sports, trading cards, utility, domain names, and more.

Additionally, it is even possible to buy virtual plots of land on the metaverse in the form of NFTs on OpenSea.


No matter what kind of NFT you are looking for, you will likely find it on the OpenSea platform.

Its marketplace also gives you access to some of the most popular NFT collections in this space – such as the Bored Ape Yacht Club and CryptoPunk collections. Moreover, OpenSea hosts exclusive drops of new NFT projects.

NFT Ranking and Watchlists

Another interesting feature of OpenSea is that it has a dedicated ranking page for NFTs. The ‘Stats’ tab of OpenSea ranks NFT collections listed on the platform in terms of trading volume, floor price, number of tokens, and other core statistics.

This tool can be extremely helpful for those looking to buy rare NFTs that are high in demand.

You will also be able to create a watchlist for NFTs, which let you track the digital tokens collections you are interested in. You will be able to find these NFTs under the ‘Watchlist’ section of your profile. It is also possible to ‘Like’ NFTs on OpenSea and tag them as favorites on your profile.

Buy NFTs

When it comes to buying NFTs on OpenSea, there are three ways you can go about it:

  • You can purchase fixed-price NFTs right away
  • You can make an offer on the NFT you are interested in
  • You can place a bid on an NFT that is listed via a live auction

The only thing you need to remember is that you should choose the same cryptocurrency as that of the respective NFT’s blockchain. For instance, if the NFT you chose is built on Solana, then you need to pay or make an offer in SOL tokens.

Further down the guide, we offer a detailed step-by-step breakdown of how to buy NFTs on OpenSea.

Create and Sell NFTs

OpenSea also makes it incredibly easy for you to create your own NFTs. Unlike other NFT marketplaces, there is no need for you to send in an application to be invited as a creator.

Instead, you only need an account to mint your own NFTs in any format you prefer.

OpenSea create

Once you have minted your NFT, you can list it for sale on OpenSea. As the creator, you are also eligible to receive royalties of up to 10% on each subsequent sale.

When listing an NFT, you can decide whether you want to sell the token via an auction, accept offers from buyers, or charge a fixed price.

OpenSea Supported Cryptocurrencies

As we noted earlier, OpenSea is a cross-blockchain NFT marketplace. Therefore, you can use more than one cryptocurrency to buy NFTs via this platform. At the time of writing, OpenSea lets you purchase non-fungible tokens using Ethereum, Wrapped Ethereum, Solana, Polygon, USDC, DAI, and a few other digital assets.

However, if you are looking to use fiat currencies such as US dollars or euros to buy NFTs on OpenSea, you will be out of luck. That said, you can easily buy cryptocurrencies from an online broker like eToro and transfer them to your digital wallet to make purchases on OpenSea.

OpenSea Supported Wallets

One of the main reasons why OpenSea is considered highly accessible is because it connects to a long list of crypto wallets. It supports over 17 different wallets, including prominent providers such as MetaMask, Coinbase Wallet, TrustWallet, Fortmatic, Venly, WalletConnect, and more.

While some of these work best as desktop extensions, others make it easy for you to buy NFTs via your cell phone.

OpenSea wallets

That said, remember that not every crypto wallet supports all blockchains hosted on OpenSea.

For instance, let’s say you connect to OpenSea via Fortmatic. This particular digital wallet does not support the Solana network. Therefore, if you are to buy an NFT built on Solana, you will need to connect to a wallet like Phantom or Glow to make the purchase.

OpenSea Fees

OpenSea has set up a simple and straightforward fee structure for its NFT marketplace – as discussed below.

Trading and Minting Fees

As with any other NFT marketplace, OpenSea charges you a commission for processing transactions. It levies 2.5% for every transaction that goes through its platform. In comparison, the marketplace allows you to buy NFTs fee-free.

OpenSea also permits users to mint NFTs for free.  That said, it is crucial to remember that you will still have to pay a gas fee to your chosen blockchain when creating NFTs.

While the gas fees on Ethereum are pretty high, other blockchains such as Solana and Klatyn are a lot more competitive. And like we discussed earlier, OpenSea also lets you mint NFTs on Polygon without paying any gas fees at all.

Creators Fees

If you are reselling an NFT, then you might also have to pay royalties to the creator of the respective non-fungible token. This fee is set by the creator and can be as high as 10%. It is also possible for the creator to adjust this fee percentage at any time.

OpenSea Mobile App

In September 2021, OpenSea launched its mobile app, which is available on both Android and iOS.

The main features accessible via the OpenSea mobile app are as follows:

  • Follow NFT collections
  • Share NFTs with others
  • Manage the NFTs held in your profile

In a nutshell, the OpenSea mobile app essentially works as a gallery that you can use to explore NFTs.

However, at the time of writing, you will not be able to buy or sell NFTs via the app.

OpenSea Security

OpenSea has made it clear that it prohibits the sale of stolen, converted, and fraudulently obtained items on its platform.

  • It also notifies you of any suspicious activity that takes place on your account and encourages you to open a support ticket in such a case.
  • Furthermore, the platform provides tips and other resources you can use to safeguard your NFTs in your private digital wallet.

However, it is worth pointing out that OpenSea encountered an attack in February 2022. According to the platform, $1.7 million of ETH tokens were stolen from users.

The attackers appear to have exploited a loophole in the Wyvern Protocol, the open-source standard used by most NFT smart contracts, including those created on OpenSea.

OpenSea Customer Service

When it comes to customer service, OpenSea has left no stone unturned. It has devised a help center that gives you access to all kinds of resources you need to get familiar with the platform.

You will also find beginner-friendly how-to guides, video tutorials, and dozens of articles related to NFTs, crypto wallets, and its marketplace.

There is also a chat feature supported by a bot to help you find the right article that you are looking for. If you wish to reach out to a customer representative, you can send a message via the platform, mentioning your email address, and your query.

You will also be able to join the OpenSea community on Twitter or Discord to engage with other users and the team itself.

How to Buy NFTs on OpenSea

By now, you know that you can buy NFTs on OpenSea using cryptocurrency only. This means that before you sign up on the platform, you need to make sure that you have a digital wallet and sufficient crypto coins.

While those like MetaMask let you buy cryptocurrencies from within the wallet itself, you will have to pay extra fees to cover the cost of processing the transaction, service charges as per the third-party provider, and gas fees.

The easier and cheaper alternative would be to use a regulated online broker like eToro.

So, let us show you how you can buy cryptocurrencies via eToro and use them to purchase NFTs on OpenSea.

Step 1: Create an Account on eToro

eToro is one of the most popular and well-reputed online brokers of today. It lets you buy Ethereum, Solana, and Polygon (MATIC) coins directly using fiat currencies, and at just a 1% fee. Moreover, eToro is heavily regulated and is licensed by the FCA, ASIC, and CySEC.

To get started with eToro, you can open an account in a matter of minutes. You can find the ‘Join Now’ button and proceed to enter your email address, along with the username and password you want to use for your account.

You will also be required to fill in your personal details, such as your full name, date of birth, home address, and phone number.


Next, you will have to go through the identity verification process. For this, you have to provide a copy of your passport or driver’s license. It is also necessary to provide a document that verifies the address you have provided. This can be in the form of a recent utility bill or bank statement.

Cryptoassets are a highly volatile unregulated investment product. No UK or EU investor protection.

Step 2: Deposit Funds to eToro

Since eToro lets you buy crypto coins using fiat currency, you will first have to add some funds to your account. The minimum deposit required is only $10 for US clients and no fees are charged.

eToro supports payments through bank transfers and credit/debit cards. You will also be able to transfer money from an e-wallet like PayPal and Neteller. If you wish to buy cryptocurrencies instantly, it is best to use a debit/credit card or an e-wallet.

Step 3: Buy Crypto on eToro

After you have added funds to your eToro account, you can find the cryptocurrency you want to buy using the search feature. For instance, if you want to buy Polygon tokens, you can enter ‘MATIC’ into the search bar.

eToro will instantly show you the result, and you can tap on the ‘Trade’ button to place an order.

Polygon eToro

eToro then loads up an order box, where you can specify the amount you want to invest in your chosen cryptocurrency. It is also possible to enter the number of digital coins you want to buy, instead of the amount.

When you are ready, you can use the ‘Open Trade’ button at the bottom of the order box to make the purchase. The cryptocurrencies you purchase will be added to the ‘Portfolio’ section of your eToro account.

Step 4: Transfer Crypto From eToro to the eToro Money App

Another advantage of eToro is that it gives you access to a free wallet that you can use to transfer cryptocurrencies. This wallet, named eToro Money, comes in the form of a mobile app, which you can download via the Apple Store or Google Play.

  • To sign into this wallet app, you can use the same credentials as your eToro brokerage account.
  • You can then go to the Portfolio’ in your eToro trading app, and choose the crypto you want to transfer.
  • From there you can ‘Edit Trade’ and click on the ‘Transfer to Wallet’ option.

eToro will then close your chosen trade on the brokerage platform and move your digital assets to the wallet app.

Step 5: Transfer Crypto From the eToro Money App to Digital Wallet

Now, OpenSea does not connect to the eToro Money app directly. Therefore, you need to complete one more simple step to transfer your crypto from the eToro Money app to your chosen digital wallet.

You can make this transaction by signing into the eToro Money app, and choosing the cryptocurrency you wish to send.

Then, you can paste the wallet address and confirm. For added security, eToro also requires you to complete an SMS verification before the transaction commences.

Step 6: Set up OpenSea Profile

Once you have added cryptocurrencies to a digital wallet of your choice, you can connect it to OpenSea.

To do this, you can navigate to the official website of OpenSea and click the wallet icon in the top right corner. Next, choose the wallet you want to use and sign in using your credentials.

OpenSea profile

When connected, you can click on the ‘Profile’ icon to set up your profile. Here, you can customize your bio, enter your email address, and set a profile photo. You will also be able to connect your OpenSea account to social networks or your website, in order to add authenticity and get verified.

Step 7: Buy NFTs on OpenSea

Next, you can browse the NFTs listed on OpenSea using the ‘Explore’ bar. You can also refer to the ‘Rankings’ section to find out the NFTs you would like to invest in.

To know more about a particular NFT, you can simply click on the token – and you will be able to see details about the collection, its transaction history, and the traits of the particular digital asset.

OpenSea buy NFT

Once you have decided on the NFT you want to purchase, you can click on the ‘Buy Now’ button and follow the prompts in your wallet. As we noted earlier, depending on the NFT you choose, you might also have to place a bid. When the transaction is complete, the NFT you purchased will be added to your wallet.
