FIO Testnet and Developer Docs Released

The wait is over!

After an year-long process of working with our FIO Members to define and codify the future of blockchain usability (see whitepaper and roadmap), we’re now ready for the wider developer ecosystem to begin integration.

FIO is excited to announce the public release of our developer guides and Testnet, including everything you need to fully integrate the FIO Protocol ahead of our mainnet launch (still on track for Q1 of 2020):

Our vision for the future of blockchain usability isn’t just to replicate the best features of the fiat system (refunds, invoicing, request for payments, etc) into siloed containers, but to make those features AND MORE a fundamental capability of every wallet and every blockchain token or coin.

Join us, come help us build the blockchain experience that the masses deserve.

Getting Support

We’re here to help developers — feel free to join our Discord or Telegram channels and ask any questions. Our team is primarily in the US, but we will assist as much as possible.

Our SDKs are fully open-sourced on GitHub, feel free to contribute!

What’s Next

For developers, you can begin the full integration of the FIO Protocol while it’s running on Testnet — this will allow you to seamlessly transition over to Mainnet once launched.

The FIO Protocol itself is now towards the end stages of optimization and security audits, and will be open sourced shortly.

For block producers: We are currently finishing up documentation specific towards running a node. Although, you can get started now if you wish (reach out to us on one of our social channels or at As a reminder, the FIO Protocol is a heavily modified fork of EOS, so experience with any EOSIO chain is largely applicable towards running a FIO node.

For wallets/exchanges/crypto payment processors: You are invited to become a FIO Member or Affiliate Member, though doing so is not required to integrate FIO. Members are given the chance to reserve a FIO Domain ahead of Mainnet, and can use this FIO Domain to reserve a FIO Crypto Handle (formerly known as FIO Address) in the format of name:domain, such as: bob:shapeshift or jon:trust, in addition to receiving some additional assistance from our team. Membership does not cost anything — feel free to get in touch at



FIO Protocol makes crypto easy by replacing all of your public wallet addresses with a single, secure, customizable crypto handle. Use this single crypto handle to send, receive, or request any type of crypto as easily as sending an email.
