Fake NFT marketplaces are phishing sites that impersonate real platforms to steal your wallet credentials or approval.
How They Work
- Scammer creates a site that looks like OpenSea, Rarible, or Blur
- Promotes it via social media, ads, or Discord
- You connect your wallet to “browse” or “mint”
- A malicious contract drains your NFTs or tokens
- Your assets are gone
Common Lures
| Lure | Example |
|---|
| Free mint | ”Mint our exclusive NFT collection!” |
| Rare find | ”Someone is selling a Bored Ape for 0.1 ETH!” |
| Platform migration | ”OpenSea is moving to a new domain — verify your collection” |
| Airdrop claim | ”Claim your free NFT airdrop” |
| Gas fee trick | ”Just pay gas to mint” (but the contract takes everything) |
How to Spot a Fake Marketplace
| Check | Real Site | Fake Site |
|---|
| URL | opensea.io | opensea-nft.xyz |
| SSL | Valid certificate | Valid but lookalike |
| Design | Polished, professional | Slightly off |
| Wallet connect | Standard flow | Asks for seed phrase |
| Trades | Active, visible | None or fake |
| Social links | Official, verified | Random accounts |
The Most Dangerous: Wallet Approval Scams
| Scam Type | What Happens |
|---|
| SetApprovalForAll | You approve the scammer to transfer all your NFTs |
| Infinite approval | You approve unlimited token spending |
| Gas drain | You “mint” but pay high gas to a malicious contract |
Red Flags
| Red Flag | Why It’s Dangerous |
|---|
| ”Connect wallet to view” | No real marketplace requires this |
| ”Mint now” button on a marketplace | Marketplaces don’t mint |
| URL has a typo or extra word | Definite fake |
| Domain is very new | Check with Whois |
| Too-good-to-be-true prices | It’s a trap |
| Asks for seed phrase | NEVER share it |
How to Stay Safe
| Rule | Why |
|---|
| Bookmark real marketplaces | Never search and click |
| Use wallet with revoke option | Revoke.cash can undo approvals |
| Use a burner wallet | Separate storage wallet |
| Check URL carefully | Look for typos |
| Check Twitter accounts | Official accounts have blue checks |
| Use wallet notifications | Monitor approvals in real time |
What to Do If Connected to a Fake Marketplace
| Step | Action |
|---|
| 1 | Revoke all approvals on Revoke.cash immediately |
| 2 | Move remaining assets to a new wallet |
| 3 | Don’t interact with the site again |
| 4 | Report the domain |
Bottom Line
Fake NFT marketplaces are phishing sites designed to drain your wallet. Bookmark the real URLs, never connect your wallet to unknown sites, and always check the URL before approving any transaction. Use Revoke.cash to manage approvals and a burner wallet for browsing unfamiliar marketplaces.
