Metamask: react native with expo not working with metamask sdk

Metamask integration questions in the react native expo project

As a native react developer using Expo, you are probably familiar with the convenience of integrating external SDKs for paying and processing payments. However, when working with metamask (previously known as Metamask), integration became increasingly complicated due to changes in its SDK.

In this article, we will explore the problems encountered when trying to integrate Metamask with a React Native Expo project, although I built it using CLI tools successfully.

The problem:

When you initially configured your Expo project using the Create-React-Native-Appcommand with the Cli (Line Interface Command) tools, everything looked good. However, after updating to Expo 0.18.1 or later and trying to integrate the Metamask SDK, the integration did not function as expected.

The question:

Unfortunately, it seems that the Metamask SDK is not compatible with the versions of Expo 0.18.1 or later. The reasons behind this are not explicitly declared in Metamask documentation, but we can deduce some potential causes:

  • New Expo dependency management: Expo has changed its focus to a more explicit module system (MVs) to manage dependencies. This change may have caused compatibility problems with older SDKs, such as Metamask.

  • Metamask SDK Goals Changes: It is possible that Metamask SDK has undergone significant updates, which broke the integration with Expo.

Alternative solutions and solutions:

Given the challenges found above, here are some potential solutions to try:

Metamask: react native with expo not working with metamask sdk

1. Downgrade for an earlier version of Metamask

Try to lower your SDK metamask from the latest version (eg V2.8.x) back to an earlier version that was compatible with Expo in previous versions.

Bash

Npm install @metamask/sdk @v1.10.0

`

2. Use an older version of Expo

If you are unable to downgrade your Metamask SDK, try to create an Expo project using an older version of the Create-React-NaTive-App command (for example, Expo 0.17.1 or anterior).

`Bash

NPX React-Native Init MyApp-Version 0.16.3

`

3. Use an older version of Metamask

If you can’t create an Expo new project, try using the older @metamask/sdk package.

Bash

Npm install @metamask/sdk @v1.7.2

`

4. Disable the authentication in your native React application

Try to disable authentication to your native React application to see if Metamask integrates works as expected.

`JavaScript

import {initializeweb3} of ‘@metamask/sdk’;

CONST WEB3 = INITALIZWEB3 ({

// Disable authentication for this application

});

`

Conclusion:

In conclusion, Metamask integration with a React Native Expo project can be a challenge due to compatibility problems with the latest version of Expo. When trying to lower or use an older version of Metamask SDK, you can solve the integration problem.

If none of these alternative solutions solve your problem, provide more details about your configuration and project code, including:

  • The Metamask SDK version you are using

  • The version of the exhibition you are segmental

  • Any error messages or stack traces that appear

This will help us better understand the problem and provide a more accurate solution.
