Complete review of the OpenSea Marketplace

OpenSea stands as the premier and most expansive NFT marketplace. It hosts an array of NFT categories such as digital artwork, collectibles, sports, and virtual universes. Users have the option to explore various collections and purchase NFTs, or to mint and sell their unique creations.

This marketplace also offers interoperability across blockchains like Ethereum, Polygon, Klatyn, and Solana. Additionally, it features a gas-free marketplace where the typical blockchain fees for buying, selling, and creating NFTs are not required.

Top benefits

Broad Spectrum of NFTs

OpenSea’s standout feature is its expansive NFT collection. It houses millions of NFTs and regularly introduces new drops and collections. The range of offerings in this marketplace is immense, allowing you to discover fresh works from emerging artists and famous NFT collections such as the Bored Ape Yacht Club.

Excellent for NFT Minting

OpenSea provides an uncomplicated process for NFT creation. The platform’s popularity can also attract more viewers to your NFT collection. If you aim to minimize fees, you can use the

OpenSea Collection Manager to mint an NFT collection without any initial gas costs. Moreover, you can establish a creator fee of up to 10%, which you earn every time one of your NFTs is sold.

User-centric Design

The design quality of NFT marketplaces varies greatly, but OpenSea excels in this regard. Its well-designed layout and ease of navigation make it user-friendly. The homepage provides a quick overview of the marketplace and highlights notable pieces, making it easy for users to learn how to explore the vast array of NFTs on OpenSea.

Reasonable Fees

OpenSea maintains a straightforward fee structure by charging a 2.5% commission on every sale, payable by the seller. This rate is competitive, if not superior, to many top NFT marketplaces, some of which charge fees as high as 5% or more.

Educational Resources

OpenSea’s blog serves as a rich resource for learning about NFTs. For beginners, it features articles on how to purchase and sell NFTs, protect oneself from scams, among other key subjects. The blog also shares news and guest posts from the creators behind various collections.

Multiple Blockchain and Payment Options

Unlike other platforms that exclusively operate on one network (most commonly the Ethereum blockchain), OpenSea extends its support to four different blockchains. It also accepts a variety of cryptocurrencies for payment.


Areas for Improvement

Prevalence of Plagiarism and Spam

The OpenSea NFT marketplace, unfortunately, is marred by an overwhelming quantity of infringing content and spam. It was revealed in January 2022 that an astounding 80% of items crafted via OpenSea’s free minting instrument were either plagiarized items, counterfeit collections, or spam. OpenSea momentarily instituted a cap on the usage of this tool, but this was quickly rescinded in response to user discontent.

OpenSea has procedures in place for reporting such transgressions, and they make an effort to expunge these as promptly as possible. The platform’s popularity has been a double-edged sword, attracting not only genuine creators but also unscrupulous actors. Hence, it is crucial for users to exercise increased vigilance when purchasing on OpenSea as opposed to more curated marketplaces.

Rampant Scamming

Being the most prominent NFT platform, OpenSea is frequently targeted by fraudsters. There have been numerous incidents, including a phishing scheme in February 2022 that resulted in the theft of hundreds of NFTs. Although NFTs you purchase or generate are stored in your private wallet and cannot be pilfered directly from OpenSea, it is still essential to be aware of phishing scams due to their prevalence.

Diminished Trust Due to Insider Trading

In September 2021, OpenSea was embroiled in a major controversy involving insider trading. It was discovered that Nate Chastain, then the platform’s Head of Product, often purchased NFTs before they became publicly visible, and subsequently sold them after a spike in their value.

This scandal, a virtual counterpart of traditional insider trading, led to Chastain’s resignation and prompted OpenSea to enforce new rules, including prohibiting the exploitation of internal information for trading purposes. Despite efforts to rectify the situation, this incident has tarnished OpenSea’s reputation, the rebuilding of which may take considerable time.


Potential Alternatives:

  • For Curated and Verified NFT Collections: Nifty Gateway reduces the risk of purchasing plagiarized content by providing curated collections, chosen from well-known digital artists’ works. It also features verified collections that, although not curated, are authenticated by the Nifty Gateway team to confirm they aren’t stolen.
  • For Exclusive Digital Art Platforms: Foundation is a platform that fosters connections between creators and collectors of digital art. Before being allowed to mint and sell NFTs, creators need an invitation from the community. This selectiveness sets Foundation apart from average marketplaces, ensuring a higher standard of quality.


Platform Features

OpenSea’s marketplace allows creators to introduce their digital works while also providing consumers with a platform for free trading. Here’s a brief overview:


OpenSea provides a platform for buying, minting, and selling NFTs, featuring various search filters like category, collection, or price. Creators can generate their own NFTs, mint NFTs sans gas fees, and assign creator fees to earn a share of revenue each time the NFT is resold.


OpenSea is compatible with Ethereum, Polygon, Klatyn, and Solana blockchains. While Ethereum is the most popular for NFTs, each blockchain offers unique advantages, providing creators with a variety of options.

Supported Wallets

OpenSea is compatible with various NFT wallets, including:

  • Metamask
  • Coinbase Wallet
  • Trust Wallet
  • Portis
  • Fortmatic/Magic
  • Venly
  • Authereum
  • Bitski
  • Dapper
  • Kaikas
  • OperaTouch
  • Phantom
  • Glow

In addition, it supports the WalletConnect protocol, enabling the connection of any NFT wallet supported by WalletConnect.

Payment Methods

OpenSea processes payments solely in cryptocurrency, accepting core currencies such as Ethereum, WETH, Solana, USD Coin, and Dai.

Fiat currency payments, like U.S. dollars, aren’t supported. OpenSea does offer an option to purchase cryptocurrency via card payment through MoonPay, although due to high fees, buying from top crypto exchanges is advised.


OpenSea operates on a simple fee model, taking a 2.5% cut from every transaction, deducted from the sale price of the NFT.

When creating an NFT on OpenSea, creators can levy creator fees up to 10%. This fee is received on every resale of that NFT, and the percentage can be adjusted at any time.


What Kind of NFTs Can You Purchase on OpenSea?

A platform for purchasing a large variety of NFTs is offered by OpenSea. You can explore a variety of NFT categories on OpenSea, including:

  • Art
  • Collectibles
  • Domain names
  • Music
  • Photography
  • Sports
  • Trading cards
  • Utility
  • Virtual worlds

It stands out as the largest marketplace of its kind and provides a broad portfolio of NFTs across key categories.


It is safe to use OpenSea Marketplace?

There have been a few security and trust-related hiccups in OpenSea’s past. The security of any NFTs you buy or mint on OpenSea is mainly in your control because they are held safely in your personal wallet.

Between 2021 and 2022, a number of security incidents involving OpenSea and its users have occurred. This includes a large phishing assault in February 2022, during which hackers allegedly stole 250 NFTs and exchanged them for $1.7 million worth of Ethereum. A user filed a $1 million lawsuit against OpenSea as a result of the incident, alleging that the platform continued to operate despite the obvious need to fix security vulnerabilities.

The issue of plagiarism has also shadowed OpenSea. While the platform allows for reporting of stolen items and removes content that infringes upon intellectual property rights, it has faced criticism over its slow response times.

It’s worth noting that most users transact on OpenSea without facing any such issues. However, it’s crucial to understand common scams, take measures to avoid them, and do thorough research before buying any NFT to ensure it’s not a stolen item.


OpenSea Could be the Right Choice for You if:

  • You’re interested in exploring one of the most diverse NFT collections available in the marketplace.
  • You’re an NFT creator seeking a platform that offers a quick and user-friendly minting process.
