Metamask disconnection problem: unresolved state management in the React
application
As a web application built on the Smart NFT contract, our team is impatient to provide an exceptional user experience. However, a crucial aspect that caused frustration – the problem of disconnection with the management of Metamask’s state.
When users press the “Disconnect” button, they expect their Metamask portfolio automatically and restores its previous connection settings. Unfortunately, this has not always been the case. This article aims to explain the problem and provide a solution to solve it.
The problem: the condition of the button disconnected without updating
During the survey, we found that when users press the “disconnect” button, the state of their Metamask portfolio does not automatically reset its initial state. Consequently, the reconnection attempt fails again, without pop-up notification or visible error message indicating whether the connection has been successful.
The context: NFT Smart Contract and React App
Our application is based on a robust state management system using Redux to manage the global state through our components. However, we encountered a problem related to the way Metamask interacts with our store during the disconnection of the portfolio.
The problem in more detail
Here is what is happening when users try to reconnect:
- By pressing “disconnection”, the user is redirected to the Metamask website.
- The Metamask Wallet application begins to connect, but due to an error, it remains disconnected from our application.
- Our React application tries to disconnect again, but due to the correctly reset of the state, it cannot reconnect.
The solution: update of the Metamask connection statement
To solve this problem, we recommend the following steps:
Step 1: update the Metamask Wallet application
- We suggest update the Metamask Wallet application to include an appropriate state management system that resets the portfolio during disconnection. This can be done by implementing Redux or other state management libraries.
- Alternatively, if you use a personalized solution to manage Metamask states, make sure it is properly managed and updates the status of the wallet correctly.
Step 2: Update of the React application
To make this change in the React application, we recommend the following:
- Update the “Discorced” function to use the appropriate state management system from step 1. This will allow our React application to automatically reset the state of the Metamask portfolio during disconnection.
- Make sure that any error management and logic linked to reconnection are updated accordingly.
Code example: Updated disconnection functionality
Here is an example of how you can update your function `disconnect 'in a separate file:
Javascript
Import {Connect} from 'react-redux';
Import {Disconnect} of './Actions/metamask';
Const Mapstatetoprops = State => {
back {};
};
Const Mapdispatchtoprops = Dispatch => {
Return {dissatcher};
};
Export Default Connect (Mapstatetoprops, Mapdispatchtoprops) (metamaskdisconnect);
` ‘
In this “disconnect” update function:
- The “Dispatch” argument is used to call the corresponding action of your Redux store.
- We also pass an empty object as a “State” parameter, which should be deleted in the future.
Conclusion
To resolve the disconnection problem with Metamask’s state management in our React application, we recommend that you update both the Metamask Wallet application and our React application to properly manage state updates Wallet. By following these steps, we can make sure that users of our Smart NFT contract application receive transparent user experience when you disconnect their metamask wallets.
