⚠️ Notice: Free FIO Handle registration is no longer available in Edge as of the upcoming release. Existing FIO Names and all other FIO functionality remain fully usable.

How to Use the FIO Protocol with the Edge App

The FIO Protocol, built by the Foundation for Interwallet Operability (FIO), is a decentralized layer that simplifies crypto by replacing complex wallet addresses with FIO Handles (e.g., "you@edge"). It runs on the FIO Chain and works with any blockchain. The Edge app (www.edge.app), a self-custody wallet, integrates FIO seamlessly. Here's how to use it.

Register a FIO Handle

To register a new FIO Handle or custom domain, visit the official FIO app at app.fio.net.
Once registered, you can manage your FIO Handle in Edge under the "FIO Names" section by tapping the three line menu at the upper right.

Link Your Wallets

Under FIO Names, map your handle to your wallet addresses (e.g., Bitcoin, Ethereum) for easy multi-asset use.
Tap on any FIO

Send Crypto

Choose an asset in Edge.
Enter the recipient's FIO Handle (e.g., "friend@edge") instead of an address—Edge handles the rest.

Request Payments

In any linked wallet tap Receive
Enter an amount and then tap "FIO Request"
Input the payer's FIO Handle plus an optional note (e.g., "Coffee"). Send the encrypted request.
