Fio Protocol is a decentralized layer for the blockchain ecosystem that integrates with crypto products like wallets, exchanges, and payment processors. It uses a single identifier called FIO Addresses to simplify the use of blockchain addresses and provides encrypted, private in-app requests for funds and metadata to transactions. The protocol runs on its own dPoS blockchain (FIO Chain) and uses the FIO Token for fees, but users do not need to directly obtain the token as indirect payments can be made through intermediaries or popular cryptocurrencies.
