FIO Protocol (FIO) is a decentralized, open-source usability solution that enables easier cryptocurrency transactions on all blockchains by replacing complex wallet addresses with a single, customizable, and human-readable Crypto Handle in the format of username@domain. FIO Crypto Handles can be used to send, receive, request, and sign any type of cryptocurrency transaction as easily as sending an email. FIO Protocol’s mission is to make cryptocurrency easy to use across every type of token and coin by removing the opportunity for human error when transacting with long-string wallet addresses on different blockchains and network types. FIO integrates into any type of decentralized application and has a growing partner ecosystem of more than 75 wallets, exchanges, marketplaces, payment processors, and gaming platforms.
