Frequently Asked Questions

What is an NFT drainer?

An NFT drainer is a malicious smart contract that tricks you into granting setApprovalForAll, then steals all your NFTs in one transaction. Our scanner detects drainer patterns before you mint.

Is the NFT scanner free?

Yes, free accounts get 10 NFT scans per day with basic risk scores. Pro users get unlimited scans, full deployer history, wash trade data, and complete approval audits.

Which chains are supported?

We support Ethereum, Polygon, BSC, Base, Arbitrum, Optimism, Avalanche, and more. All EVM-compatible chains with GoPlus and Moralis coverage.

How does the Collection Health Score work?

We score 5 dimensions (contract safety, holder distribution, trading integrity, metadata resilience, team reputation) on a 0-100 scale, then combine them into an overall health score.

Can I check if my NFT approvals are dangerous?

Yes! Use the Approval Audit tab to scan any wallet. We flag dangerous approvals and show you which contracts can move your NFTs, with risk levels and revoke recommendations.
