FIO NFT Signatures

FIO NFT Signatures are the first decentralized solution to help creators and collectors on every blockchain protect themselves from NFT forgeries in a cryptographic and self-sovereign way.

Sign NFTs on any blockchain with FIO Crypto Handles: unique digital identities that are easy to share with fans. They’re NFTs themselves, fully decentralized and secured by private keys.

FIO NFT Signatures secure off-chain data by writing critical NFT info to the FIO blockchain: NFT chain type, address, token ID and URI, a hash of off-chain image, and the creator’s site URL.

Verify signature directly in NFT platforms, or use the FIO NFT Validator to authenticate with a simple search for FIO Crypto Handle, contract address, image hash, or the NFT image itself.

FIO NFT Signatures are live on Unique.one and are coming to all favorite NFT platforms soon. Start signing now with the first solution built to stop NFT forgery in a decentralized way.
