MetaMask is one of the most popular cryptocurrency wallets, widely used for managing assets and interacting with decentralized applications. While it defaults to the Ethereum network, it is fully compatible with other Ethereum Virtual Machine (EVM) chains, including Ethereum Classic (ETC). This guide provides a clear, step-by-step walkthrough for adding and using the ETC network within your MetaMask wallet.
Why Use MetaMask for Ethereum Classic?
Ethereum Classic is a longstanding blockchain that maintains the original Ethereum chain following the 2016 hard fork. It offers a decentralized and immutable environment for smart contracts and transactions. Using MetaMask with ETC allows you to:
- Securely store ETC and other compatible tokens.
- Engage with ETC-based decentralized applications (dApps).
- Seamlessly switch between multiple EVM networks using the same wallet interface.
Since both Ethereum and Ethereum Classic use the same address format, you can use your existing MetaMask account across both networks without creating new keys or addresses.
Prerequisites
Before you start, ensure you have:
- The MetaMask extension installed in your browser.
- An unlocked MetaMask wallet with at least one account set up.
- A basic understanding of how to navigate the MetaMask interface.
Step-by-Step Guide to Adding ETC to MetaMask
Step 1: Unlock Your MetaMask Wallet
Open your browser, click the MetaMask icon, and enter your password to unlock your wallet. By default, you will likely see the Ethereum Mainnet as your active network.
Step 2: Open the Network Selection Menu
Click on the network dropdown menu at the top of the MetaMask window. This usually displays the currently selected network (e.g., "Ethereum Mainnet"). A list of predefined networks will appear, including various Ethereum testnets.
Step 3: Select "Add Network"
Scroll to the bottom of the network list and click on "Add Network." In some versions of MetaMask, this may appear as "Custom RPC." This option allows you to manually input the details of a new blockchain network.
Step 4: Enter Ethereum Classic Network Details
A form will appear requesting specific network parameters. Enter the following details exactly to configure MetaMask for Ethereum Classic:
- Network Name:
Ethereum Classic - New RPC URL:
https://etc.rivet.link - Chain ID:
61 - Currency Symbol (optional):
ETC - Block Explorer URL (optional):
https://blockscout.com/etc/mainnet/
These parameters are critical for ensuring a correct and secure connection to the ETC network.
Step 5: Save the Network
Double-check that all information is entered correctly, then click "Save." MetaMask will now switch to the newly added Ethereum Classic network.
Step 6: Verify the Connection
Once saved, the network dropdown should now show "Ethereum Classic" as the active network. Your account address remains unchanged, but the balance will now reflect any ETC held on that address rather than ETH.
Important Considerations
- RPC Providers: The RPC endpoint used in this guide (
https://etc.rivet.link) is provided by Rivet under contract with the ETC Cooperative. For alternatives, you can explore other reliable RPC providers listed in the official Ethereum Classic documentation. - Chain ID: The Chain ID for Ethereum Classic Mainnet is always
61. Using an incorrect ID may lead to failed transactions or loss of funds. - Account Safety: Your existing Ethereum account is automatically used on ETC. Always ensure you are on the intended network before approving any transaction.
- Block Explorers: Adding a block explorer URL is optional but highly recommended. It allows you to easily view transaction details and account history directly from MetaMask.

Switching Between Ethereum and Ethereum Classic
A significant advantage of using MetaMask is the ability to manage assets on multiple blockchains effortlessly. Since both Ethereum and Ethereum Classic use the same address format, you can switch networks at any time without affecting your holdings.
- To switch back to Ethereum Mainnet, open the network dropdown and select "Ethereum Mainnet."
- To return to ETC, select "Ethereum Classic" from the same list.
Your account balance and displayed currency will update automatically based on the selected network.
Troubleshooting Common Issues
- Incorrect Balance Display: If your ETC balance does not appear, ensure you are connected to the correct network ("Ethereum Classic") and that you have entered the RPC URL correctly.
- Transaction Failures: Always verify the network before sending transactions. Sending ETC to an Ethereum address or vice versa can result in permanent loss.
- Network Connection Errors: If MetaMask cannot connect to the RPC endpoint, try using an alternative RPC URL from the official ETC endpoints list.
Frequently Asked Questions
Can I use the same MetaMask account for both ETH and ETC?
Yes. Because both networks utilize the same cryptographic address format, a single MetaMask account can hold and transact both ETH on the Ethereum network and ETC on the Ethereum Classic network. Your seed phrase and private keys manage the same address on both chains.
What is the Chain ID for Ethereum Classic, and why is it important?
The Chain ID for Ethereum Classic Mainnet is 61. This numeric identifier is crucial as it ensures that transactions are broadcast to the correct blockchain network. Using the wrong Chain ID could result in transactions being sent to an invalid or unintended network.
Are there any risks in adding a custom network like ETC to MetaMask?
The primary risk involves entering incorrect network details, which might lead to failed transactions or interaction with malicious networks. Always use official and verified parameters from trusted sources like the Ethereum Classic official website or community repositories.
What should I do if the RPC endpoint I added is slow or unresponsive?
You can edit the network settings in MetaMask to replace the RPC URL with an alternative endpoint. The Ethereum Classic community provides several reliable options. To edit, go to Settings > Networks, click on "Ethereum Classic," and update the RPC URL field.
Is it necessary to add a block explorer URL?
While optional, adding a block explorer URL is highly recommended. It provides convenient access to view transaction histories, verify successful transactions, and inspect smart contracts directly from your MetaMask interface, enhancing transparency and security.
Can I interact with all ETC dApps using MetaMask?
Most decentralized applications built for Ethereum Classic are compatible with MetaMask. However, always ensure the dApp supports network integration via MetaMask. Some applications might require specific configurations or might only be accessible through other wallet providers.
Conclusion
Integrating Ethereum Classic with your MetaMask wallet is a straightforward process that significantly enhances your ability to manage diverse digital assets and engage with multiple blockchain ecosystems. By following the detailed steps above, you can ensure a secure and correct setup.
The interoperability between Ethereum and Ethereum Classic via a single wallet highlights the flexibility of EVM-compatible chains. Always prioritize security by double-checking network details before conducting transactions and consider using a hardware wallet for storing large amounts of cryptocurrency.
