Is OpenSea safe?

OpenSea is a legitimate NFT marketplace, and using it is about as safe as the wallet habits of the person using it. The company itself is not a scam. The risk comes mostly from impostors, phishing links and transactions users approve without reading. How marketplaces work in general is covered in what is an NFT marketplace.

Is OpenSea legit or a scam?

OpenSea is one of the best-known NFT marketplaces, and US regulators have looked at it closely. In August 2024 the SEC sent it a Wells notice, a warning that it was considering enforcement over the NFTs listed on the site. The Block reported on February 21, 2025 that the SEC had closed that investigation and did not recommend action.

The platform has had incidents. In June 2022 an employee at Customer.io, OpenSea's email delivery partner, downloaded and shared users' email addresses. Wallets were not exposed, but OpenSea warned of a higher risk of phishing emails, and anyone who gave it an email address was told to assume they were affected.

Is OpenSea safe to use?

The site's help center lists the scams it sees most often. As of its October 2024 guidance, OpenSea says it:

• does not send transaction failure emails or ask for funds to cover "gas"
• will not send unsolicited direct messages on social media
• will not ask you to scan a QR code to fix an error or enable a sale
• never needs a developer, agent or middleman to complete a sale

It adds that genuine support comes only through its Help Center or Discord, and that any site whose address is not opensea.io is fake. A buyer who reports an error and asks you to send money is running a scam.

Your wallet is the other half. Signing a malicious listing or approval can hand control of your NFTs to an attacker, which is how wallet drainers work. Old permissions can be cleared using the steps in how to revoke token approvals.

Is OpenSea still a thing, or is it dead?

It is still running. In May 2025 OpenSea moved every user to a rebuilt platform called OS2, which added trading of fungible tokens, including Solana tokens, and cross-chain swaps. The Block reported at the time that OpenSea had regained the top spot among Ethereum NFT marketplaces by trading volume, after years behind Blur.

As of November 2026, OpenSea's help center lists 27 compatible blockchains, among them Ethereum, Base, Solana, Polygon and Arbitrum. The company also announced a SEA token. In March 2026 it postponed a planned March 30 launch, with CEO Devin Finzer pointing to difficult market conditions, so OpenSea's own channels are the place to check its status.

NFT trading overall is far below its 2021 peak, which is a separate question from whether OpenSea is safe. That wider picture is covered in are NFTs dead.
