What Is FIO Protocol
Get to Know the FIO Protocol

FIO Protocol is powered by Layer 1 FIO Chain purpose-built with many innovative features to help wallets hide the complexity of blockchain transactions across all blockchains.


It all starts with a handle ..

FIO Handle

Secure, customizable, censorship-resistant, and human-readable handle, which replaces all your public wallet addresses on all blockchains. It’s also an NFT that is fully in your control and allows you to use many of the features of the FIO Protocol.

FIO Request
Censorship-resistant and encrypted request for crypto payment, which can be sent between any two wallets for any token to ensure error-free transaction. Think Venmo payment request for crypto.
Learn More
FIO Chain
FIO Chain is a fully decentralized public Delegated Proof of Stake (DPoS) blockchain that is designed specifically to support the the unique usability requirements of the FIO Protocol.
Learn More
NFT Signature
On-chain attestation by the NFT owner on any blockchain that the signed NFT was created by the FIO Handle owner. Can also include NFT hash to ensure it was not altered.
Learn More
FIO Data
Censorship-resistant and encrypted metadata about a specific transaction on any blockchain. Think check memo for crypto.
Learn More


Allows users to initiate transactions using human-readable and memorable identifiers like "john@edgewallet" or "jane@gold".
Just like Bitcoin, transactions between parties are cryptographically signed by a private key solely in control of its owner.
Just like Bitcoin, FIO Protocol is powered by a public and fully decentralized FIO Chain that is not controlled by a single, centralized entity.
Sensitive counter-party information, such as FIO Request or FIO Data details are end-to-end encrypted so that only the sender and receiver can see it.
Once integrated into a wallet, the FIO Protocol works with any blockchain and cryptocurrency without any integration required by those chains.


There are a number of solutions in the market, which at quick glance attempt to solve similar problems. Here are some of the key differentiators to consider when comparing FIO Protocol to other naming solutions.

Not Only a Name
FIO Protocol offers many usability-enhancing features.
Not Only a Name

FIO Protocol overlaps with many naming solutions in that it offers a human-readable name. However, FIO Handle is just one of the elements of the Protocol, and other usability-enhancing features, such as FIO Request, FIO Data, NFT Signature make for a far more compelling product.

No Name Collisions
FIO Domains are designed without extensions, which also makes Top Level Domains (TLDs).
No Name Collisions

FIO Domains, which are part of FIO Handles, are purposely designed without extensions. This way they do not collide with other naming systems or ICANN, the undisputed global authority on web domains. Conversely, other web3 naming systems are already experiencing collision as seen in .coin and .wallet feuds. By not having extensions, FIO avoids the issue in the short-term and makes FIO Domains de facto Top Level Domains (TLDs). In the long-term FIO has the flexibility to append any globally recognizable extension (e.g. .fio) to the FIO Domain.

Truly Decentralized
FIO Protocol is powered by a public FIO Chain with no central entity.
Truly Decentralized

FIO Protocol is powered by a public FIO Chain and not controlled by any central entity. Although other naming protocols may also use a blockchain, the creators are often in control of the smart contract. If a single entity can decide which names to sell or can cancel registrations, is it really decentralized? Is the user really in control of their name?

Blockchain transactions are inherently complex.

Blockchain transactions are inherently complex. Most user don’t understand what it means to sign transactions, interact with a smart contracts or why they have to pay gas fees on every action. Other naming solutions, which rely on general purpose Layer 1 blockchains such as Ethereum, force users to manage their names using the same complex smart contract interactions that often require separate plug-ins, wallets and Layer 1 tokens. Since FIO Chain has been purpose-built as a usability protocol, it’s much easier for integrators to shield users from these complexities by integrating FIO Handles natively into their applications. Gas-free interactions ensure most users never have to think about FIO Tokens.

Works with All Blockchains
Really! FIO Handles support every token on every blockchain.
Works with All Blockchains

Really! FIO Handles support every token on every blockchain. Most other naming protocols allow their names to be mapped only to certain pre-defined tokens on pre-defined blockchains. FIO Protocol does not have such restrictions. If a new blockchain launches tomorrow, it will be supported without any integration. The Foundation maintains a list of chain, token codes and additional attributes, to make it easy for wallets to communicate using the same standard.
