Welcome to the Synthetix system documentation. These pages contain a description of how Synthetix operates; provided are high-level discussions of the system mechanics, as well as thorough technical specifications of the smart contract architecture and API. We hope this assists users and developers to understand the system, and to build on top of it.


  • Litepaper: The Synthetix Litepaper has a detailed overview of how the Synthetix protocol functions.
  • Community Page: The online community has built an excellent site with a large backlog of resources, explanations, and links that is perfect for any newcomers.
  • Official Blog: Stay up-to-date with all official news from the team at the Synthetix blog.
  • SIPs (Synthetix Improvement Proposals): The Synthetix ecosystem is managed by a core team, with suggestions and improvements from the community in the form of Synthetix Improvement Proposals (SIPs) and Synthetix Configuration Change Proposal (SCCPs). Past and present SIPs and SCCPs are hosted on To suggest a new SIPs, create an issue on the SIPs repo.
