We are excited to announce that FIO has teamed up with AirNFTs to integrate FIO NFT Signatures into the AirNFTs platform to give users a new way to prevent NFT forgeries and protect content permanence.

AirNFTs is an innovative NFT marketplace built on BNB Chain, Fantom and Polygon focusing highly on user experience and ease of use to create, buy, sell and trade NFTs.

AirNFTs offer cutting-edge advantages such as lightning speed, and extremely low fees, in many cases less than $1. AirNFTS also allows you to Earn BNB, FTM and Matic, as well as an impressive NFT Launchpad where you can raise funds for your project and get access to their partners and NFT community.

From all the features AirNFTs provide, mention aside deserve royalties.“Royalties AirNFTs” allow creators earn a percentage on secondary sales of the NFTs. This means you earn not just from a single sale but also all future sales. All of this is achieved through a pleasant and user-friendly experience.

Benefits for Users

Adding FIO NFT Signatures is another step in improving that user experience.

FIO NFT Signatures protects buyers and sellers of NFTs by giving the creator the ability to sign the NFT using their personalized FIO Crypto Handle.

A FIO Crypto Handle replaces that long string public address vulnerable to errors and other exploits with a simple, human-readable address. The long string public key address is then replaced with the FIO Crypto Handle in the format of username@domain or, for example, janedoe@Airnfts.

NFT creators can now use their own personalized FIO Crypto Handle to sign NFTs which protects buyers and helps sellers by providing a source of authentication that’s easily verifiable on the FIO blockchain.

AirNFTs are already building on a cross-chain future, which makes this partnership even more important as FIO is a blockchain agnostic protocol. In other words, FIO NFT Signatures works for NFTs minted on all blockchains.

Another great feature of NFT Signatures is that it helps to protect permanence of the NFT’s Metadata by storing a hash of it on the FIO blockchain.

Many do not realize that most NFTs do not store images, videos, audio, or other properties of the NFT on-chain. Being able to store a hash of that data on-chain protects the NFT and its data by creating permanence.

This integration enables NFT creators to sign their NFTs during the minting process using their unique, customizable FIO Crypto Handle — a human-readable address (e.g. username@domain) that replaces long-string public wallet addresses.

NFT creators can also sign their NFTs off-marketplace — even retroactively — using the FIO Dashboard. FIO Crypto Handles are NFTs unto themselves secured by private keys on the FIO blockchain and, by design, cannot be duplicated or forged.

Here’s an example of how it works: If Leonardo da Vinci was alive today and wanted to release an NFT collection, he could claim the FIO Crypto Handle leonardo@davinci in the FIO Dashboard (or in any wallet or exchange that has integrated FIO Domains) and use this FIO Crypto Handle to sign his NFTs.

He could then publicize his FIO Crypto Handle to his audience and fans — across his social media profiles, on his website, within his newsletter, on his NFT marketplace gallery pages themselves, etc. — letting everyone know that he will sign all of his NFTs with his FIO Crypto Handle leonardo@davinci, and that any NFT not signed with leonardo@davinici (no matter how authenticate it might appear) is a forgery.
