Your portfolios
Portfolios are private watchlists saved in this browser. They do not prove wallet ownership and are not stored onchain. Clearing site data removes them, and they do not sync between devices or browsers. No wallet connection is needed.

Advanced: Check a specific NFT collection
Enter an ERC-721 collection contract address to check how many NFTs from that collection are held by the wallets in this portfolio. This field does not accept a wallet address.
Optional. It is separate from loading the portfolio, and ONE does not browse or list your NFTs.
Want these wallets verified?
This view is unverified. Anyone can type any address. A Verified ONE proves control by having each wallet sign, then records one public identity address onchain. No funds move.
