imToken now supports connecting with extension wallets through QR-based connection, allowing you to manage imToken (offline mode) through MetaMask for more secure and convenient offline transaction signature.
Preparation:
- Use imToken version 2.14.0 or above and ensure that, starting from wallet creation and mnemonic generation, imToken remains in offline mode throughout the whole process.
- Make sure your computer has installed MetaMask.
How to Connect MetaMask to imToken in Offline Mode
1. On the imToken wallet page, click ">" - "Connect with other wallets" to generate a QR code.
2. In MetaMask, click the account selection button and click “Add wallet - ” "Connect a hardware wallet".
3. Click "Other QR wallet", then use your computer's camera to scan the QR code displayed on imToken.
4. MetaMask will generate multiple addresses based on the QR code. Choose the address corresponding to your imToken and click "Unlock" to complete the wallet connection.
5. Once connected, you can use MetaMask to view imToken's assets, transaction history, and initiate transfers on various chains.
How to Initiate a Transfer
1. In MetaMask, tap "Send", select the network and token, enter the recipient address and amount, then tap "Continue".
2. Review the network, transfer amount, network fee, and other transaction details, then click "Confirm" to generate the QR code for the signing request.
3. On the imToken wallet page, click "Offline Sign" and use your phone to scan MetaMask's QR code. After verifying the transfer information, click "Send" to generate a signed QR code.
Note: Before offline signing on imToken, ensure that your imToken is switched to the corresponding chain. For example, if MetaMask initiates a transfer on Ethereum mainnet, make sure imToken is also on that chain.
4. Click "Get Signature" in MetaMask, use your computer to scan imToken's QR code to send the transaction to the chain. After completion, you can view the transfer record in "Activity".
Note: Please keep your backup mnemonic phrase safe. The correct way to back it up is using physical media, such as writing it down by hand on a piece of paper or using a imKey HeirBOX Mnemonic Storage. Because these physical media cannot be connected to the internet or transfer information between electronic devices, they can truly save your mnemonic phrase offline.
