Network Configuration
Production RPC endpoints, chain IDs, and explorer URLs for Ethereum Classic mainnet (Chain 61) and Mordor testnet (Chain 63). Drop-in configuration for MetaMask, Hardhat, Foundry, and any EVM-compatible toolchain. Both networks run Proof-of-Work consensus under the Spiral EVM specification, with the Olympia upgrade pending activation on both chains.

Developer Tooling
Ethereum Classic tracks the Ethereum EVM specification, which means the full Ethereum development toolchain works on ETC without modification. Hardhat, Foundry, ethers.js, viem, wagmi — every major tool connects with a single configuration parameter. Set Chain ID to 61, point your RPC at etc.rivet.link, and deploy.

Developer Resources
The full breadth of Ethereum development infrastructure — client libraries, on-chain analytics, governance tooling, and protocol documentation — configured for Ethereum Classic. Same EVM specification, same standards, same developer experience. Everything you need to ship on ETC is already familiar.
Client Implementations
Multi-client architecture eliminates single points of failure at the protocol layer. Independent implementations in distinct languages, maintained by separate teams, ensure the network can withstand the discontinuation or compromise of any single codebase. Fukuii, Core-Geth, and ETC compatibility plugins for Besu, Erigon, Go-Ethereum, and Nethermind provide implementation diversity without fragmenting the ecosystem.

Network Hashrate
ETChash
Mining Algorithm
GPU + ASIC
Compatible Hardware
Ethereum Classic is the only EVM-compatible chain secured by Proof-of-Work. When Ethereum transitioned to Proof-of-Stake, ETC absorbed the majority of the ETHash mining ecosystem — including established ASIC manufacturers like Bitmain and Jasminer. ETChash supports both ASIC efficiency for commercial-grade operations and GPU accessibility for global participation, decentralizing hashrate across geographies and reducing supply chain risk. Run fukuii to participate in block production and earn ETC rewards.

Network Hashrate
Mining Equipment
ETChash supports dedicated ASIC hardware and consumer GPU rigs, distributing hashrate across a broad base of independent operators. ASIC efficiency enables commercial-scale operations; GPU accessibility brings in global retail miners — together diversifying the security budget and reducing single-vendor supply chain risk.

Mining Pools
Active ETChash mining pools contributing to Ethereum Classic's security budget. Pool selection affects expected earnings variance, payout frequency, and infrastructure dependence. Hashrate is estimated from recent block attribution — larger pools appear at the top.

Payout types
- PPS
- Pay Per Share — Fixed payout per valid share submitted, regardless of whether the pool finds a block. Variance-free for miners; pool bears the risk.
- PPS+
- Pay Per Share Plus — PPS for the block reward, plus a proportional share of transaction fees. Slightly higher expected earnings than standard PPS.
- FPPS
- Full Pay Per Share — PPS that includes an average of expected transaction fees in the per-share rate. Smooths fee income across all miners.
- PPLNS
- Pay Per Last N Shares — Payout proportional to shares submitted in the most recent window. Rewards consistent miners and discourages pool-hopping.
- PROP
- Proportional — Block reward split proportionally among miners who contributed shares to that specific block. Simple, but earnings vary with block luck.
- RBPPS
- Round-Based Pay Per Share — PPS calculated per mining round (block-to-block). Combines the low-variance of PPS with round-scoped accounting.
- SOLO
- Solo Mining via Pool — Miner receives the full block reward if they find a block; nothing if they don't. Pool provides infrastructure only. High variance.
