Congratulations to ETC for a successful Agharta hard-fork! We’re happy to have participated in client readiness and championing the adoption of the upgrade. Q4 was focused a lot on improving infrastructure tooling with new features and enhancements as well as hard-fork readiness.

Client team


ETC Core is committed to the maintenance and support for Multi-Geth since our team launched in January of 2019. Multi-Geth is a swiss-army-knife client allowing users to run Ethereum Classic, Ethereum, and related testnets. Multi-Geth can be easily managed using Jade service runner or it’s app alternative, Jade Desktop.

  • Added Agharta hard-fork support
  • Added Mordor testnet chain support
  • OpenRPC maintenance

Geth-Classic reaches end-of-life

Geth-Classic has served the immutable fortress since the DAO hard-fork and made its last stand for the Agharta hard-fork. This client will no longer be maintained. If you’re running a Geth-Classic client, please migrate to Multi-Geth, Parity Ethereum, or Hyperledger Besu as soon as possible. Doing so ensures you’re running a maintained client and keep-up with future network upgrades.

Jade is an awesome JSON-RPC service manager that provides demonization, installation, and discovery for JSON-RPC based services. Jade currently supports Multi-Geth allowing users to easily manage an Ethereum Classic, Ethereum, or related testnet.

  • Bumped Multi-Geth for Agharta hard-fork support.
  • Releases v1.5.0–1.8.0 focused on bug fixes and enhancements.

Jade Desktop

Jade Desktop bundles the Jade service manager into an easy to use Desktop application.
