Introduction
We’re excited to announce the dYdX Chain Github repositories are now fully public! Our introduction of the dYdX Chain (v4) was the first step toward making dYdX fully decentralized and transparent—making the code public is the next step. All core repositories, including the validator software, indexer, web front end, and supporting libraries are now public on GitHub.
The dYdX Chain code is still being tested (try out the Testnet!) and we aim to release the production ready code later this year. Once complete, we encourage the community to use these repositories as a starting point to grow the dYdX ecosystem.
