Enter an NFT contract address and token ID to see its collection, current owner, traits, and artwork across Ethereum, Base, Arbitrum, Optimism, Polygon, and BNB Chain — read directly from the blockchain.
Frequently asked questions
- What do I need to look up an NFT?
- The NFT's contract address (a 0x… address) and its token ID (a number), plus the chain it lives on. You'll find both in the URL on a marketplace like OpenSea or on a block explorer.
- Does it support ERC-721 and ERC-1155?
- Yes. We read ERC-721 ownership (ownerOf) when available and fall back to the ERC-1155 metadata URI, so both standards are covered.
- Why is the image sometimes missing?
- Some NFTs store their artwork on IPFS gateways that can be slow or offline, and a few use formats we can't preview. We always show the on-chain data and links even when the image can't load.
- Which chains are supported?
- Ethereum, Base, Arbitrum, Optimism, Polygon, and BNB Chain. Make sure to pick the chain the NFT was minted on.
