Metamask: Can’t connect metamask mobile to DApp
Medamask connectivity problem: Mobile cannot be connected to Desktop Dapp
If you create a decentralized application (DAPP) on the Ethereum blockchain, connecting to your mobile wallet and your browser is of crucial importance for the seamless user experience. However, some users have reported that they have connectivity problems when using Metamask, the popular decentralized finance in -tD bags and the DAPPS platform (Defi).
In this article we will deal with the topic of metamask that do not connect to a desktop dapp on mobile devices.
Code analysis
The provided code snippet seems to be a starting point for the establishment of a metamask connection in a desktop environment. The essential import statements include:
`JavaScript
Import {web3} from ‘Web3’;
`
However, the rest of the code is incomplete and does not deal with a specific problem.
Debugging of the Codes
To fix this problem, we will add basic console protocol to inspect the Metamask connection process. We will also check whether all the necessary modules are imported and variables defined.
`JavaScript
console.log (‘Metamast recognized on desktop’);
If (Window.ethereum) {
attempt {
Console.log (‘Connect to Ethereum Blockchain …’);
Const web3 = new web3 (window.thereum);
// … (the rest of the code remains the same)
`
Test the connection
To check whether metamask is properly manufactured, we use a simple test script. Create a new file called Test.js and add the following code:
`JavaScript
Const test = async () => {
attempt {
Wait web3.eth.net.ws.connect ({{{{{{{{{{{{{{{{{
Host: ‘Localhost’, // Set up with your local knot -URL or IP address
Port: 8545,
Time crossing: 3000, // Set a time crossing to prevent errors
});
console.log (‘connected to metamast’);
Const Metamaskurr = Warte Web3.eth.net.Ws.getmatata ({{{{{{{{{{{{{{{{{{{
Host: ‘Localhost’, // Set up with your local knot -URL or IP address
Port: 8545,
});
console.log (metamask url: $ {metamaskurt});
return;
} Catch (error) {
console.error (‘errors made with metamask:’, error);
Return wrong;
}
};
Test (). Then ((result) => console.log (result)). catch ((error) => console.error (error));
`
Tests on mobile devices
Now change the code to test the connection on a mobile device. We will use a local knot -URL and a port port instead of “Localhost”. Replace “Localhost” with your local knot -URL or IP address.
`JavaScript
Const test = async () => {
attempt {
Const web3 = new web3 (new web3.providers.httpprovider (‘http: // localhost: 8545’))); // replace with your mobile knot -url
console.log (‘connected to metamast’);
Const Metamaskurr = Warte Web3.eth.net.Ws.getmatata ({{{{{{{{{{{{{{{{{{{
Host: ‘Localhost’, // Set up with your local knot -URL or IP address
Port: 8545,
});
console.log (metamask url: $ {metamaskurt});
return;
} Catch (error) {
console.error (‘errors made with metamask:’, error);
Return wrong;
}
};
`
Check the problem
To check whether the problem is related to the mobile device, we can use a tool like “tracing.jsor" Metamask -Devtools "to inspect the network requirements and errors.
JavaScript
Const tracing = demands (‘tracing-js’);
Tracing.on (‘http’, (request) => {
Console.log (http request: $ {Request.method} $ {Request.url});
});
console.error (‘errors made with metamask:’, error);
`
Diploma
By analyzing the code, testing the connection on desktop and mobile devices and the use of debugging tools such as “tracing.js`” we have identified the problem of metamask that does not connect to a desktop -dapp on mobile devices.
