Ethereum Classic (ETC) is a decentralized blockchain platform that enables the execution of smart contracts—applications that run exactly as programmed without downtime, censorship, or third-party interference. As a continuation of the original Ethereum chain before the 2016 fork, Ethereum Classic upholds the principle of "code is law," preserving immutability and decentralization. Built on its native cryptocurrency, ETC, this ecosystem supports trustless digital asset management and programmable money that operates independently of traditional financial institutions.
For those interested in participating in network security and earning rewards, mining remains a viable entry point. This comprehensive guide walks you through the entire process of setting up and running an ETC mining operation using modern tools and best practices.
Why Mine Ethereum Classic?
Mining Ethereum Classic not only supports the network’s decentralization but also offers financial incentives. Miners validate transactions and secure the blockchain by solving complex cryptographic puzzles, earning newly minted ETC tokens in return. While Ethereum has transitioned to proof-of-stake, Ethereum Classic continues to operate under proof-of-work (PoW), making it one of the few major PoW blockchains still open to GPU miners.
Key benefits include:
- Ongoing block rewards for miners
- Lower entry barrier compared to ASIC-dominated networks
- Active development and community support
- Compatibility with widely available GPU hardware

Step 1: Set Up Your ETC Wallet
Before you start mining, you need a secure wallet to receive your ETC earnings. You have several options:
- Exchange deposit addresses – Convenient if you plan to trade immediately, but less secure for long-term storage.
- Full node wallets – Offer maximum control and privacy by syncing the entire blockchain.
- Mobile wallets like Bitpie – User-friendly apps that support ETC and other cryptocurrencies with strong security features.
Always ensure your wallet address is correctly formatted and test it with a small transaction before starting full-scale mining.
Step 2: Choose and Install Mining Software
To mine ETC efficiently, you’ll need reliable mining software. One popular option is Wondermole, a system designed for large-scale mining operations with centralized management capabilities.
You can download:
- Wondermole server image for diskless servers
- Virtual machine image for Windows environments
These tools allow remote deployment, monitoring, and configuration of multiple mining rigs from a single interface.
Ensure your system meets the minimum requirements:
- Stable internet connection
- Supported GPU drivers (NVIDIA/AMD)
- BIOS configured for network/PXE boot (required for diskless setups)
Step 3: Configure the Mining System
Server-Side Setup
First-Time Registration & Mineyard Configuration
- Register a new account via mobile number on the Wondermole platform.
- Upon first login, your account will be automatically bound to a new mineyard (mining farm), granting full administrative privileges.
- Access the web dashboard at
a.wondermole.comto manage permissions and settings remotely. - Change the default system password (
minerhub) during initial setup and store it securely. - Assign a name to your mineyard to complete registration.
Basic Settings
- Click the Settings button.
- Navigate to Server Network and confirm it matches your local LAN settings.
- Go to System Image Management, select the latest Wondermole miner image, and download it.
- Click Apply in the bottom-right corner to save changes.
Mining Configuration
Kernel Selection
Click the gear icon in the top-right corner and go to Mining Program Version Management.
Choose a mining kernel based on your priorities:
- Stable kernels: Lower hashrate but fewer crashes—ideal for beginners
- High-performance kernels: Higher hash output but may require tuning for stability
Select the one optimized for Ethash (the PoW algorithm used by ETC).
Wallet Address Setup
Under Default Group → Group Configuration, input your ETC wallet address where mined coins will be sent.
Double-check for accuracy—any typo could result in permanent loss of funds.
Mining Pool Configuration
Set both:
- Primary Pool: Main destination for share submissions
- Backup Pool: Automatically used if the primary goes offline
This ensures continuous operation even during pool outages.
Popular ETC mining pools include UUPool and others supporting stratum protocols.
Dual Mining (Optional)
Enable auxiliary coin mining (e.g., TON or other compatible coins) if your GPU allows efficient dual-algo processing. This increases overall profitability without significant performance trade-offs.
Click Save Settings after completing all configurations.
Step 4: Add Mining Rigs
You can add miners in two ways:
Option A: Manual Addition (Single Rig)
- Click Add Miner > Add Single
Enter:
- Worker name (e.g.,
rig01) - MAC address
- IP address
- Worker name (e.g.,
- For sub-account mining, include the correct sub-account identifier
Option B: Network Scan
- Select Scan Miners
- Check “All Machines” and click Start Scan
- All devices on the same local network running compatible firmware will appear automatically
Once detected, they’ll begin syncing with your configured settings.
Step 5: Start Mining & Monitor Performance
Miner Status Check
On the miner side, look for:
- Successful boot via PXE/network
- GPU detection
- Connection to the mining pool
- Hashrate reporting
Monitoring Dashboard
From the web interface:
- Confirm all GPUs are recognized
- Verify status shows “Normal”
- Observe real-time hashrate (e.g., MH/s)
- Watch for rejected shares or overheating alerts
Verify Pool Activity
Visit uupool.cn/etc/your_worker_name or search by worker ID on www.uupool.cn/etc.
Within minutes of submitting valid shares, your miner should appear on the pool’s stats page with live performance data.

Frequently Asked Questions (FAQ)
Q: Is Ethereum Classic still profitable to mine in 2025?
A: Yes, especially with efficient GPUs and low electricity costs. While profitability fluctuates with market prices and network difficulty, many miners find ETC a sustainable option due to its active development and commitment to proof-of-work.
Q: Can I use consumer-grade GPUs to mine ETC?
A: Absolutely. Most modern NVIDIA and AMD graphics cards support Ethash mining. Cards like the RTX 3060 Ti, RX 6700 XT, and similar models deliver strong performance per watt.
Q: Do I need an ASIC miner for Ethereum Classic?
A: No. Unlike Bitcoin, ETC uses the Ethash algorithm, which is ASIC-resistant and optimized for GPU mining, keeping the field accessible to individual miners.
Q: What happens if my main mining pool goes down?
A: If you've configured a backup pool, your rig will automatically switch to it, minimizing downtime and ensuring continuous hashing.
Q: How often are mining rewards distributed?
A: Rewards depend on the payout structure of your chosen pool—common methods include PPLNS (Pay Per Last N Shares) and proportional payouts, typically issued every few hours once minimum thresholds are met.
Q: Is cloud mining a good alternative to setting up my own rig?
A: While cloud mining removes hardware hassles, it often comes with higher fees and reduced transparency. Self-mining offers better long-term control and potentially higher returns if managed well.
By following this guide, you're now equipped to launch a functional Ethereum Classic mining setup. With careful configuration, ongoing monitoring, and smart resource management, mining ETC can be both technically rewarding and financially viable.
