How Can You Tell if an NFT Marketplace Is Fake?

A fake NFT marketplace works on the same basic principle as a fake exchange — look convincing enough, long enough, to get a wallet connected and a transaction signed. The checks that reveal one largely mirror what already applies to fake exchanges, adapted to NFTs specifically.

Why NFT Marketplaces Are a Specific, Attractive Target

Someone browsing NFT marketplaces is, by definition, already prepared to connect a wallet and sign transactions — the exact behavior a fake platform needs from a victim. This makes NFT marketplace impersonation a particularly efficient setup compared to scams needing to first convince someone to take that step from scratch.

Check the Domain Against the Genuine Platform

The same domain-verification principle that applies everywhere else applies here — comparing the exact address against the known, official domain of the marketplace being impersonated, watching for the same kinds of small alterations used in other phishing domains.

Why a Convincing Catalog of Listed NFTs Doesn't Confirm Legitimacy

A fake marketplace can display real NFT images and metadata pulled directly from the genuine collection's actual on-chain data — displaying accurate images and details requires no special access and doesn't confirm that purchasing through this specific interface actually transfers genuine ownership.

What a Fake Marketplace Purchase Might Actually Do

Rather than transferring the genuine NFT, a fake marketplace's "buy" button can be configured to request a broader wallet approval or a malicious signature instead — the interface can show what looks like a normal purchase flow while the underlying transaction being requested does something entirely different from what's displayed.

Why Search Results and Ads Can Surface Fake Marketplaces

Similar to fake exchange listings, fake NFT marketplace links can appear through paid search advertisements or through social media posts, sometimes ranking prominently for searches related to a popular or trending collection.

Why Connecting a Wallet to Browse Feels Lower-Risk Than It Is

Browsing a marketplace and connecting a wallet to see your own NFT holdings feels like a passive action — but connecting itself reveals wallet information that a fake platform can use to inform what it requests from you next, and sets up whatever transaction request follows.

What to Do to Verify Before Purchasing

Navigating to the marketplace through a bookmarked, previously verified domain rather than a search result or shared link, and checking that any purchase transaction's prompt matches what a straightforward NFT purchase should actually request before confirming.

Check a marketplace's domain and any requested transaction before purchasing an NFT through it — a convincing catalog of real NFT images doesn't confirm the platform itself is genuine.
