Tell Me More


ETC Core is the leading Ethereum Classic core development team.


From fundamental specifications, tooling suites, and resources, we deliver open-source tooling for the Ethereum Classic ecosystem. We strongly believe in cross-chain compatability and implement that philosophy in our projects. You can use many of our tools on any EVM-based blockchain.


We actively support the long term development of the ETC protocol. We do this by championing improvement specifications to adoption and maintaining Multi-Geth.


We are commited to maximizing the capabilities of the EthereumStack through our EVM-LLVM project and compiler improvement initiatives.
