Core-Geth

Recommended

Current primary production client for Ethereum Classic. Fork of go-ethereum maintained by ETC Cooperative. Expected to transition to Fukuii after the Olympia network upgrade.

GoWindowsmacOSLinux

Docs GitHub

Hyperledger Besu

EVM testing and development client with ETC support. Suitable for development environments but not recommended for production mining nodes as upstream deprecated PoW support.

JavaWindowsmacOSLinux

Docs GitHub

Fukuii

The only native ETC client. Revived fork of the Mantis client (IOHK) with modern Scala 3 architecture. Currently in Alpha testing for the Olympia network upgrade (2026), after which it will become the primary production client.
