 # Technology
 The FIOJS Library is built using tsc, to generate the JavaScript files.  FIOJS is a utility/helper sdk used by the TypeScript SDK.  This utility library provides encryption, packing and signing capabilities.  Use the TypeScript SDK for FIO API support and private/public key creation.

 Visit the [FIO Protocol Developer Hub](https://developers.fioprotocol.io) to get information on FIO SDK versions. Only use an SDK that has a major version number that matches the current FIO Protocol blockchain major version number (e.g. 1.x.x).
