How to Create ETC, ETHW, and OCTA Wallets Using MetaMask

·

Cryptocurrencies built on the Ethash algorithm have evolved significantly since Ethereum’s transition to proof-of-stake in September 2022. Ethereum Classic (ETC), EthereumPoW (ETHW), and OctaSpace (OCTA) are prominent proof-of-work forks that continue to support decentralized mining and blockchain operations. While ASIC miners now dominate the Ethash mining landscape, GPU mining has become largely obsolete due to increased network difficulty. However, securely managing your mined or acquired coins remains essential—and that starts with setting up a reliable wallet.

This guide walks you through creating a unified wallet for ETC, ETHW, and OCTA using MetaMask, one of the most trusted and widely used digital wallets in the crypto ecosystem. With a single seed phrase and address, MetaMask allows seamless interaction across multiple Ethereum-based networks—making it ideal for users who want flexibility, security, and ease of use.

Why Use MetaMask for Ethash-Based Coins?

MetaMask is more than just an Ethereum wallet—it's a gateway to the broader decentralized web (Web3). It supports any blockchain compatible with the Ethereum Virtual Machine (EVM), which includes ETC, ETHW, and OCTA. This means you can manage all three assets from one interface without needing separate wallets.

Important Security Notes

While MetaMask offers convenience, your security depends entirely on how well you protect your device and recovery phrase:

Step-by-Step: Setting Up Your MetaMask Wallet

Follow these steps to create a secure MetaMask wallet capable of holding ETC, ETHW, and OCTA.

Step 1: Download and Install MetaMask

Visit the official website and download the extension for your browser (Chrome, Firefox, Edge, etc.) or install the mobile app.

Step 2: Create a New Wallet

  1. Open MetaMask and select "Create a new wallet".
  2. Accept the terms of service by clicking "I Agree".
  3. Set a strong password. Consider using a password manager or generator to ensure complexity.
  4. Confirm your password and proceed.

Step 3: Secure Your Seed Phrase

You’ll be shown a 12-word secret recovery phrase. This is the master key to your wallet—if lost, you lose access to all funds permanently.

After recording, MetaMask will test your memory by asking you to re-enter specific words in order. Complete this step to verify your backup.

Step 4: Copy Your Wallet Address

Once setup is complete, click the copy icon next to your wallet address. This same address will be used across all networks—ETC, ETHW, and OCTA.

Adding ETC, ETHW, and OCTA Networks to MetaMask

By default, MetaMask connects to the Ethereum Mainnet (ETH). To use other Ethash-based coins, you must manually add their custom networks.

How to Add a Custom Network

  1. Open MetaMask and click the network dropdown (top center).
  2. Select "Add network", then choose "Add a network manually".
  3. Enter the following details for each coin:

Ethereum Classic (ETC)

EthereumPoW (ETHW)

OctaSpace (OCTA)

Click "Save" after entering each set of data.

💡 Tip: The same wallet address works across all added networks. You don’t need multiple addresses—just switch networks when sending or receiving different coins.

Switching Between Networks in MetaMask

After adding the networks, switching is simple:

  1. Open MetaMask.
  2. Click the current network name (e.g., "Ethereum Mainnet").
  3. Select the desired network: Ethereum Classic, Ethereum PoW, or OctaSpace.
  4. Your interface updates instantly—you’re now operating on the new chain.

This allows you to check balances, send transactions, and interact with dApps specific to each network—all from one wallet.

Frequently Asked Questions (FAQ)

Can I use the same MetaMask address for ETC, ETHW, and OCTA?

Yes. Since all three are EVM-compatible, your public address remains the same across networks. Just ensure you're on the correct network when transacting.

Is MetaMask safe for storing proof-of-work coins?

MetaMask is secure if used correctly. Always guard your seed phrase, avoid phishing sites, and keep software updated.

What happens if I send ETH to my ETC address?

Sending ETH to an ETC address on the wrong network may result in lost funds. Always double-check the active network before transferring.

Do I need separate wallets for ASIC-mined coins?

No. As long as the coin runs on an EVM-compatible blockchain, MetaMask can support it via custom RPC configuration.

Can I recover my wallet on another device?

Yes. Use your 12-word seed phrase to restore access on any device or wallet client that supports BIP39 recovery.

Why can't I see my balance after adding a network?

Final Thoughts

Managing multiple Ethash-based cryptocurrencies doesn’t have to be complicated. With MetaMask, you gain a powerful, user-friendly tool that consolidates control over ETC, ETHW, and OCTA under one roof. By following best practices for setup and security, you can confidently store, receive, and transfer assets across these growing blockchain ecosystems.

Whether you're a miner transitioning from Ethereum or an investor exploring alternative proof-of-work chains, having a properly configured wallet is your first step toward long-term success in Web3.
