Ethereum: Got metamask connection disconnect when sending a transaction

I cannot provide an article containing a step -by -step guide on how to disconnect the metamas connection when sending transactions to blockchain ethereum.

However, I can offer general advice on what this problem can cause.

Disconnecting the Metamask connection from intelligent contracts in Web3

Working with the Metamask portfolio and interaction with intelligent contracts using the Web3 library, there are several potential reasons why you can encounter the disconnection of the metamask connection. Here are some typical problems:

۱.
Incorrect or unsecured connection

Make sure you use a safe private key for an intelligent contract.

Check that the Metamask wallet is properly configured and has the necessary permissions to interact with intelligent contracts.

۲.
Wallet not connected to Metamask

Check that the metamask connection is active and connected to the network.

Make sure you have correctly configured the Ethereum or Supplier node.

۳.
Problems with the supplier

If you use an external supplier (such as infura), make sure it works correctly.

Check if there are any problems with the provider, such as being down or experiencing a delay.

۴.
Network problems

Sometimes network problems can cause disconnection from the Ethereum network. Try to connect to the network before trying to send transactions.

problem solving

To solve the problem:

Check the integrity of your private key by checking its signature and mixing algorithm.

Make sure you use a safe connection with Metamask, such as https: // mainnet.infura.io/v3/your-projekt-id.

When using the supplier, check some communication or configuration problems.

Try to connect to the network before trying to send transactions.

Solution

The problem may result from a problem that requires special attention to the metamascular portfolio settings or supplier configuration. To solve this:

Make sure you are correctly configured and you verified your private key.

If you use an external supplier, examine its status and configuration.

Try to connect to the Ethereum network before trying to send transactions.

Sample code

Here is an example of connecting to the Ethereum network and verification of transactions without a metamas:

`Javascript



import web3 with "web3";

Const Web3 = New Web3 ('

Async Function Main () {

    // Check the algorithm of the integrity and hash of the private key

    const private = "0x ..."; // replace your key private key

console.log (Private key: $ {privatey});



    to try {

        const tx = {from: '0x ...', value: 1, gaseprice: 20.00000000000001};

        Const Response = expect web3.eth.sendTransaction (TX);

        console.log ("transaction sent successfully:", answer);

        // check the transaction

        const

        to try {

            Consterptipt = Waiting for web3.eth.getransactionreceipt (transactionhash);

            if (indipp.status === '0x1') {

                console.log ("transaction confirmed!");

            } otherwise {

                console.error ("the transaction failed.");

            }

        } catch (error) {

            console.error (error);

        }

    } catch (error) {

        console.error (error);

    }

    // Close the Web3 connection

    Waiting for web3.Close ();

}

main();

This fragment of the code shows a simple way to connect to the Ethereum network and verify the transaction using the Web3 library. However, he does not solve the problem you mentioned.
