In November 2022, the ETC Cooperative launched the rebranded "Catacomb ETC Wallet"—a fully redesigned multi-signature wallet for Ethereum Classic (ETC). This guide walks you through the new interface and explains how to create a secure ETC multi-sig wallet on the Ethereum Classic network.
Step-by-Step Guide to Creating an ETC Multi-Signature Wallet
1. Visit the Ethereum Classic Multi-Sig Wallet
Navigate to the official ETC multi-signature wallet portal:
👉 ETC Multi-Signature Wallet
2. Configure the Network
On the homepage, select your network from the dropdown menu in the top-right corner.
3. Choose "Classic"
You’ll see two options:
- Classic: The main ETC blockchain.
- Mordor: A test network for developers.
Select "Classic" for deploying your wallet on the ETC mainnet.
4. Connect Your Wallet
Click the red "Connect Wallet" button in the top-right corner.
5. Click "Connect"
A prompt will appear—click "Connect" to proceed.
6. Select Your Wallet Provider
Choose your preferred wallet (e.g., MetaMask) from the menu. For this example, we’ll use MetaMask.
8. Choose the Address to Use
MetaMask will display your ETC wallet addresses. Select the one you want to link and click "Next."
9. Confirm Connection
Click "Connect" to finalize the link between MetaMask and the ETC multi-sig wallet.
10. Create a New Multi-Signature Wallet
Click "Create New Safe" to start setting up your wallet.
11. Name Your Wallet
Enter a descriptive name (e.g., "DBA - Multisig") and click "Next."
13. Add Wallet Owners
Specify the wallet owners by:
- Clicking "Add New Owner."
- Entering the ETC addresses of the owners (e.g., Donald, Bob, Alice).
- Setting the threshold for transaction approvals (e.g., 2 of 3 means 2 signatures are required).
Click "Next" to proceed.
14. Review Your Settings
Verify the details and estimated network fees. If correct, click "Next" to deploy the wallet.
15. Confirm Wallet Creation
Note your new multi-sig wallet address—this is where you’ll send/receive ETC. Confirm the transaction in MetaMask.
16. Wait for Deployment
The wallet will display the deployment status. Wait a few minutes for the smart contract to activate on the ETC blockchain.
17. Processing Completion
Do not close the window while processing. Once done, the wallet will be ready for use.
19. Wallet Successfully Created!
Your ETC multi-signature wallet now appears on the homepage. In the next guide, we’ll explain how to use it for transactions!
