What is a FIO Domain?

FIO Domains are the #1 solution for personalizing your Web3 identity, and the only fully decentralized way to customize that identity from beginning to end. They can be used to create unique FIO Crypto Handles, which let you build a completely custom Web3 name (e.g. name@customdomain) without needing to use a standardized .domain extension.

FIO Crypto Handles can be mapped to any kind of cryptocurrency wallet and used as a single, user-friendly identifier in place of lengthy crypto wallet addresses. Use that FIO Crypto Handle — personalized with a custom FIO Domain — to send, receive, request, or even securely sign any type of crypto transaction. Meaning…

How to Wrap a FIO Domain

Wrapping is the process of taking a token from one blockchain and making it available for use on another. All FIO Domains are NFTs on the FIO blockchain, which means they are secured by private keys and can be freely transferred between FIO accounts, users, and wallets by the private key holder.

With FIO Domain wrapping now available on Polygon, you can turn your FIO Domain NFTs into ERC-721 NFTs, which gives you the ability to list and trade your FIO Domains on your favorite NFT marketplaces.

Similarly, you will now be able to purchase FIO Domains directly from other holders on NFT marketplaces; after purchase, you can choose to keep your FIO Domains wrapped on Polygon for future resale or you can unwrap them to move them back to the FIO blockchain.

Unwrapping makes your FIO Domain available for the creation of FIO Crypto Handles, which are your fully customizable Web3 identity and can be used in place of all of your long, complex wallet addresses.

TL;DR — FIO Domains and FIO Crypto Handles

  • Grab your favorite custom FIO Domains before they’re gone! These can be whatever you want them to be: @yourname, @yourbrand, @yourfavoritemusician, @yourfavoritesportsteam, @yourfavoritecolor, etc.
  • Collect your favorite FIO Domains to keep for yourself or wrap them for sale on any Polygon-enabled NFT marketplace. Because FIO Domains are NFTs, you have full custody via your own private keys: your keys, your Domains, your control over how they’re used.
  • Add usernames to your favorite FIO Domains to create unique crypto handles. Your unique crypto handles look like username@yourdomain and are your fully personalized Web3 identity that can be used to replace any or all of your complex wallet addresses (no matter the token, coin, or blockchain).
