Metamask integration issues in the React Native Expo project
As a React Native developer using Expo, you’re probably familiar with the convenience of integrating external SDKs for authentication and payment processing. However, working with MetaMask (formerly known as MetaMask) made integration significantly more difficult due to changes in their SDK.
In this article, we will look at the problems that arise when trying to integrate Metamask with a React Native Expo project, despite successfully building it using the CLI tools.
Problem:
When you initially set up your Expo project using the create-react-native-app command with the CLI (Command Line Interface) tools, everything seemed fine. However, after upgrading to Expo 0.18.1 or later and trying to integrate the Metamask SDK, the integration did not work properly.
Problem:
Unfortunately, it appears that the Metamask SDK is incompatible with Expo 0.18.1 or later. The reasons are not clearly stated in the Metamask documentation, but we can highlight a few possible reasons:
- New Dependency Management in Expo: Expo has focused on a more intuitive system of Dependency Management Modules (MVS). This change could cause compatibility issues with older SDKs such as Metamask.
- Changes in Metamask SDK:
Metamask SDK may have been significantly updated, which broke the integration with Expo.
Problems and Solutions:
Given the above problems, we suggest trying several possible solutions:
1. Go back to the previous version of Metamask
Try rolling back the Metamask SDK from the latest version (eg v2.8.x) to a previous version that was compatible with Expo in previous versions.
“Bash”
npm install @metamask/sdk@v1.10.0
2. Use an older version of ExpoIf you cannot update the Metamask SDK, try creating a new Expo project using an older version of the create-react-native-app' command (for example, Expo 0.17.1 or earlier).
"Bash"
npx react-native init MyApp --version 0.16.3
3. Use an old version of Metamask
If you are unable to create a new Expo project, try using the old "@metamask/sdk" package.
"Bash"
npm install @metamask/sdk@v1.7.2
4. Disable authentication in your React Native applicationTry turning off authentication in your React Native app to check if the Metamask integration is working properly.
javascript
import {initializeWeb3} from '@metamask/sdk';
const web3 = initializeWeb3({
// Disable authentication for this application
});
``
Conclusion:
In summary, the integration of Metamask with the React Native Expo project may be difficult due to compatibility issues with the latest version of Expo. Attempting to rollback to a previous version or using an older version of the Metamask SDK may resolve the integration issue.
If none of these solutions resolve the issue, please provide additional information about your project's configuration and code, including:
- Metamask SDK version in use
- The version of Expo you are applying for
- Any error messages or stack traces are displayed
This will help us better understand the problem and provide a more accurate solution.
