FIO NFT Signatures

Protect Your NFTs.

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.

001 Prove Provenance

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.

002 Secure Permanence

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.

003 Validate Creator

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.
