MetaMask supports EVM-compatible blockchains (those that run smart contracts) and is widely used across various DApp platforms. In addition to its built-in accounts, MetaMask also supports a QR-based protocol for integrating with hardware wallets.

The D'CENT app utilizes this QR-based protocol to enable seamless integration between D'CENT accounts (EVM-compatible) and MetaMask.

Download and Install MetaMask

How to connect D’CENT Wallet with MetaMask

This function is supported only in Biometric Wallet and App Wallet(Software) mode. Minimum supported version

  • Biometric Wallet firmware version: 2.19.7 or higher

  • D’CENT App version: Android (5.16.1 or higher) / iOS (5.16.2 or higher)

The QR-based protocol supported by the MetaMask can only be used when a camera(webcam) is installed on the computer.

If you use an external camera device, please check if the camera supports the auto focuing and QR code scanning function.

[Step 1] Preparing to connect with MetaMask in the D’CENT App

1. After running the D’CENT App, enter the Discovery tab.

2. Select MetaMask Integration from the list.

3. Tap on Go button.

4. On the MetaMask integration screen, click on Connect Metamask account button.

5. Select the account to be linked from the account selection list and click on Connect button.

6. After confirming that the QR code is generated, Proceed to [Step 2].

DO NOT disclose QR code to others.

[Step 2] Connect the D'CENT Wallet by scanning the QR code on your computer

3. After selecting QR-based, click the Continue button at the bottom.

4. It switches to the QR code scanning page.

5. Scan the QR code prepared in [Step 1] using the camera on your computer.

6. When the QR code scan is completed normally, it will be converted to the account selection page.

If the camera on your computer is having difficulty reading the QR code, please try again after adjusting the screen brightness to max on your phone.

7. On the account selection page, select First account and click Unlock.

(In the case of a D’CENT account, it doesn’t matter which account you choose because all the accounts shown in the QR scan list are the same.)
