OpenSea Review 2026: Fees, Volume & Trust Score

OpenSea is a peer-to-peer marketplace for non-fungible tokens (NFTs). You use it to buy, sell, create and trade NFTs, but it never holds your assets: you connect your own crypto wallet, and every purchase or sale settles on the blockchain between that wallet and another user’s.

OpenSea has described itself as the first and largest NFT marketplace. It covers art, music, collectibles, virtual land, sports assets, domain names and utility NFTs such as membership passes, across several blockchains with Ethereum as the default.

Who OpenSea May Suit

OpenSea fits people who want to buy, sell or mint NFTs across many categories and chains in one place, and who are comfortable managing their own wallet. If you are new to crypto, the practical first step is buying ETH or another supported token on an exchange such as those in our Kraken review or Binance review, then moving it to a self-custody wallet. If you only want price exposure to crypto rather than ownership of unique digital items, an exchange is the more direct tool.

What OpenSea Is and Who Runs It

OpenSea was founded in 2017 by Devin Finzer and Alex Atallah and went through the Y Combinator startup accelerator. Its pitch was one general marketplace where any compatible NFT could be listed, discovered and sold.

It is not a crypto exchange in the usual sense. A centralized exchange such as those in our best crypto exchanges and apps roundup takes custody of customer funds, matches orders in an internal book and lets you deposit dollars. OpenSea does none of those things. It is a front end and a set of smart contracts that let wallet holders list items and accept payment directly from one another.

Owning an NFT means your wallet address holds a unique token on-chain. It does not by itself give you the copyright to the underlying image or file. The rights that come with an NFT depend on the terms its creator attaches.

How OpenSea Works: Non-Custodial Trading and Seaport

When you connect a wallet, OpenSea reads which NFTs that address holds and displays them on your profile. When you buy, the NFT moves to your wallet address, not to an OpenSea account balance. When you sell, the payment goes to your wallet. If OpenSea’s website went offline, the NFTs would still be in your wallet and could be traded elsewhere.

The trade-off is that OpenSea cannot recover anything for you. There is no password reset for a lost seed phrase and no reversal of a transaction you signed by mistake. The marketplace can delist items or flag suspicious collections, but control of the assets rests entirely with whoever holds the wallet’s private keys.

The trading logic runs on Seaport, an open-source Web3 marketplace protocol OpenSea developed and launched in 2022. OpenSea introduced it as a way to cut the gas fees users pay on transactions. Because Seaport is open source, other developers can build on the same contracts.

Wallets and Connecting to OpenSea

You need a compatible crypto wallet before you can do anything beyond browsing. Supported wallets include:

MetaMask
Coinbase Wallet (WalletLink)
Trust Wallet
Fortmatic/Magic
Bitski
Bitget
Core
Phantom
Solflare
Glow
Opera Touch (mobile only)
WalletConnect, which links many other mobile wallets
Kaikas

The connection process is the same whichever wallet you use. Go to OpenSea.io, open the login option in the menu, choose your wallet type and approve the connection prompt that your wallet displays. Approving a connection shares your public address. It does not give OpenSea your private key.

Once connected, your profile shows the NFTs your address owns. Any action that writes to the blockchain, such as buying, listing on some chains or transferring, requires the network’s native token to pay gas: ETH on Ethereum, SOL on Solana, and so on. Keep some on hand in the same wallet.

Finding NFTs: Explore, Stats and Collection Pages

The Explore Page

The Explore page is the main way to browse, by category or by collection or item name. Top and trending collections are ranked per category over the last 24 hours, seven days, 30 days or all time. You can narrow results by blockchain, price range and category, and choose between single items and bundles.

The Stats Page

The Stats page is the more analytical view. By default it ranks top collections over the last 24 hours. You can filter by category and blockchain, then sort by volume, time period, price change, floor price, sales, unique owners and number of items listed.

These measures answer different questions. Floor price is the lowest current asking price in a collection, which tells you the cheapest entry point, not what a typical item is worth. Volume is the total value traded over the period and can be driven by a few large sales. Unique owners relative to the collection’s size gives a rough sense of how concentrated ownership is. None of these figures shows whether the trading reflects genuine demand or wallets trading with themselves.

Collection Pages

Opening a collection brings up its creator’s name, the number of items, total volume, floor price and best current offer, often with links to the project’s social channels. Beyond the Items tab, you can view activity, offers and analytics.

Within Items, five status filters help sort the collection:

All: every NFT in the collection.
Listed: items currently for sale.
On Auction: items in an auction, with their bids.
New: recently listed items.
Has Offers: items with at least one open offer.

How to Buy NFTs on OpenSea

OpenSea is priced and settled in crypto. Payment tokens it has accepted on most listings include ETH, wrapped ether (WETH), AVAX, USDC, KLAY and DAI, with a few others on specific chains. Fiat currency is not accepted as payment on the marketplace itself, so you typically buy crypto on an exchange first and send it to your wallet.

Once you find an item, you have two routes:

Buy Now purchases the NFT at the listed price. Your wallet opens a transaction to sign, and once it confirms on-chain, the NFT lands in your wallet.
Make Offer proposes your own price. The seller can accept or ignore it, and nothing transfers until they accept.

Offers are where WETH matters. Native ETH cannot be pre-authorized for a smart contract to spend later, but WETH, as a standard ERC-20 token, can. So before making offers you convert ETH to WETH, a one-to-one wrap, and approve the marketplace contract to draw it if the seller accepts. If your WETH balance drops below the offer amount before it expires, the offer cannot execute.

Costs to Account For

A trade on OpenSea can carry three separate costs, and they fall on different parties:

Gas fees go to the blockchain network, not to OpenSea. On Ethereum they rise and fall with network demand, so the same purchase can cost noticeably more to execute at a busy time. Other supported chains generally have much lower transaction costs. Some first-time actions, such as approving a collection for sale, can require their own transaction.
The marketplace fee is OpenSea’s charge, deducted from the seller’s proceeds.
Creator earnings (royalties) are a percentage set by the collection’s creator and paid from the sale.

OpenSea has revised its marketplace fee rate more than once and has changed how it enforces creator earnings, so the figures in older guides may not match what you see when listing. Check the fee breakdown on the listing screen before you confirm.

A hypothetical example shows how the pieces combine. Say an NFT sells for 1 ETH, with an assumed 2.5% marketplace fee and a 5% creator earning. The seller receives 1 − 0.025 − 0.05 = 0.925 ETH, before any gas the seller paid to list or approve. The buyer pays 1 ETH plus gas. These rates are illustrative only, not OpenSea’s current terms.

There is also currency risk. An item priced in ETH changes value in dollar terms whenever ETH moves, even if its ETH floor price stays flat, so a gain measured in ETH can still be a loss in dollars. Our crypto profit calculator can help you work through both.

How to Create NFTs on OpenSea

Creators can mint individual NFTs or whole collections of digital items such as artwork and music. The Create option opens an item creation page where you upload the file and add a name and description. You can customize the item with properties, levels and stats, which are the traits buyers often filter by within a collection.

Ethereum is the default chain, but you can mint on another supported blockchain. That choice affects your buyers as much as you: an item minted on a lower-cost chain is cheaper to trade, but buyers need a wallet and funds on that chain. Once you finish customizing and click Create, the item is ready to list.

How to Sell NFTs on OpenSea

To sell, open your profile, choose the NFT from your wallet and click Sell on the item page. You can sell a single item or group several into a bundle. The listing page then asks for the price and the type of sale.

Fixed-Price Sale

You set one price and choose how long the listing stays active. Anyone can buy at that price until it sells, expires or you cancel.

Timed-Auction Sale

Timed auctions come in two forms:

Sell to highest bidder: buyers place bids during the auction window, and the highest bid wins.
Sell with declining price: the price starts high and falls over the auction period until someone buys.

Timed auctions have not been supported on mobile, or for ERC-1155 tokens with multiple owners. ERC-1155 is a token standard that allows several identical copies of one item, unlike ERC-721, where each token is one of a kind. If you hold a share of a multi-edition item, a fixed-price listing may be your only route.

Protecting Your Wallet and NFTs

Scammers target NFT users through fake sites, fake support staff and malicious links. These steps address the most common routes to losing assets:

Never share your secret recovery phrase with anyone, including someone claiming to be OpenSea support.
Confirm you are on the official OpenSea domain before connecting a wallet. Look-alike domains can differ by a single character.
While your wallet is connected in a browser, avoid unknown, broken or suspicious links.
Use a unique password for the email and accounts tied to your wallet, different from those on other sites.
Enable two-factor authentication wherever it is offered.
Consider a hardware wallet for valuable NFTs, so private keys never sit on an internet-connected device.
Do not open attachments in emails claiming to be from OpenSea. The company does not send files to users, and it has previously warned users about phishing after a security incident at one of its email vendors.

Strengths and Trade-Offs

Breadth. OpenSea lists millions of collections across art, gaming, collectibles, domains and memberships on several chains, so most well-known NFTs can be found there. Competitors such as Rarible, LooksRare, Magic Eden, Binance NFT and Nifty Gateway each focus on narrower segments or specific chains.

Discovery tools. The Stats rankings, category and chain filters, and collection-level data on floor price, volume and offers give buyers more to work with than a simple storefront.

Self-custody cuts both ways. An OpenSea outage or account problem cannot trap your assets, but there is no chargeback and no fiat payment. Beginners must set up a wallet, fund it through a separate exchange and understand gas before buying anything.

Open listing. Anyone can mint and list, which keeps the catalog broad but means copycat collections and fake listings can appear alongside originals. Check the collection’s creator address and official links rather than relying on the name or image.

How we checked OpenSea

We visited OpenSea on 13 November 2026, connecting from Tallinn, Estonia. The home page opened normally. It now presents the site as a token trading and NFT marketplace, so the pitch reaches beyond NFTs alone. We scrolled to the footer, then moved to the feed, where we clicked the figures “$167.1K”, “$1.3M”, “$4.2M” and “$14.9M” to expand the details behind them. Two collection pages loaded as well: Enter Elysium, listed at 0.0799 HYPE, and Statements, listed at 0.4276 ETH.

Fees were harder to pin down. We opened four rule articles from the feed, but none of the pages gave us a marketplace fee rate we could match against the page text. That means we cannot confirm the current seller fee. We did not connect a wallet or attempt a purchase, so we did not test what checkout requires. Disclosures were thin. The site named no legal entity, showed no licence or registration number, made no regulator statement and displayed no risk warning that we found.

No register check was possible. With no licence claimed, there was nothing for us to look up in a register we can query. Trustpilot, which we read on 13 November 2026, showed 1.3/5 from 182 reviews, with 85% of them one-star and 4% five-star. The profile is unclaimed. Of the 8 newest reviews, the company had replied to 0. The Wayback Machine’s first capture of opensea.io dates to 2018-02-15. An archive date alone cannot prove the same operator ran the domain back then.

We still cannot say who legally operates the marketplace, because the site did not tell us, and we would treat that gap with caution until OpenSea names its entity.

Risks to Weigh

NFT prices can be illiquid and volatile. A floor price is only an asking price. Selling at it, or at all, depends on a buyer showing up. Thinly traded collections may have no bids for long stretches.

Smart contract and signature risk is the other major exposure. Malicious sites can prompt you to sign approvals that let an attacker move your NFTs or tokens. Read what a wallet prompt is asking for before approving. Use a separate wallet for minting new or unfamiliar projects if you hold valuable items elsewhere.
