FIO Handle
Project Links
Description
FIO Handle is a secure, customizable, censorship-resistant, human-readable Web3 identifier. It can be mapped to blockchain addresses, used for payment requests, linked to social media, associated with a personalized profile page, and used to sign NFTs. A FIO Handle is an NFT controlled by its holder’s private key on the FIO Chain; it does not expire, can be transferred to another public key, and includes 100 gas-free transactions.Category: Decentralised Identity
FIO Chain
Project Links
Description
FIO Chain is a live public DPoS blockchain purpose-built for the FIO Protocol. Powered by the open-source Antelope technology stack and operated by independent block producers, it uses the native FIO Token to incentivize ecosystem participants. Its stated capabilities include bundled gas-free transactions for FIO Handles, stable premium-transaction fees, encrypted transaction details, governance proxying, and public FIO Improvement Proposals.Category: L1
FIO Domains
Project Links
Description
FIO Domains are NFT-based domains on the FIO Chain that form part of FIO Handles, enabling branded or personalized handle identities. Owners control them with a private key, can transfer them to another public key, and may make a domain public for handle registration or keep it private for owner-only registration; domains can also be transferred to Polygon for marketplace listing.Category: NFT Issuance Platform
FIO Request
Project Links
Description
FIO Request enables cryptographically verified, end-to-end encrypted payment requests between FIO Handles. It supports crypto tokens across blockchains, Lightning invoices, fiat payments, and public-address URI parameters, helping recipients confirm payment details without manually entering addresses or networks.Category: Payments Infrastructure
FIO Data
Project Links
Description
FIO Data is a FIO Protocol feature that securely sends end-to-end encrypted transaction metadata between two FIO Handles on the FIO Chain. It can reference transactions on any blockchain, be matched by a client using the unique blockchain transaction ID, and be sent in response to a FIO Request or with a simple crypto transfer.Category: Messaging Protocol
