Ethereum: Got metamask connection disconnect when sending a transaction

I cannot give an article that contains a Step -By -STEP guide on how to disconnect the metamk connection by sending transactions to the Ethereum blockchain.

I offer some general tips on what this problem can cause.

Ethereum: Got metamask connection disconnect when sending a transaction

Disconnect the metamask connection to smart contracts on Web3

When you work with the metamk’s wallet and interact with the web3 directory with smart contracts, there are many possible reasons why you find the metamask relationship. Here are some common problems:

1.
Invalid or unsafe connection

  • Make sure you use a secure private key for your smart contract.

  • Make sure the Metamask wallet is correctly configured and has the permissions necessary to interact with intelligent contracts.

2.

  • Make sure the METAMSK connection is active and connected to the network.

  • Make sure you have correctly configured the Ethereum node or your supplier.

3.
Supplier problems

  • If you use a third party supplier (such as Infura), make sure it works properly.

  • Make sure there are connection problems with the supplier, such as inactive or delay.

4.
red problems

  • Occasionally, network problems can cause detachment from the Ethereum network. Try to connect to the network before trying to send transactions.

Problem solving steps

Solving the problem:

  • Check the integrity of the private key by checking the signature and hash algorithm.

  • Be sure to use a secure connection to METAMSK, such as https: // mainnet.infura.io/v3/thood-id “.

  • If you are using a supplier, check any problem with the connection or configuration.

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

solution

The problem may be due to the configuration of the metamash wallet or supplier settings. To solve this:

  • Make sure the private key is configured and correctly controlled.

  • If you use a third party service provider, examine your condition and configuration.

  • Try to connect to the Ethereum network before sending transactions.

example code

Here’s an example of how to connect to the Ethereum network and check a transaction without metamsk connection:

`Javascript

Importing 'Web3' Web3;

Const web3 = new web3 ('

Async Main Function () {

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

Const Privatekey = "0x ..."; // replace the real private key

Console.log (Private key: $ {private});

attempt {

CONST TX = {from: '0x ...', Value: 1, Gasprice: 20.000000000001};

consth answer = web3.eth.sendtransection (TX);

Console.log ("The transaction has been successfully sent:", answer);

// check the transaction

Const transactionhash = reply.Hash;

attempt {

Consto receipt = Alea web3.eth.ettransactisrecetipt (transaction);

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

Console.log ("Confirmed Transaction!");

} others {

Console.Error ("decreasing transaction");

}

} CAPT (error) {

Console.Error (error);

}

} CAPT (error) {

Console.Error (error);

}

// close the web3 connection

Wait Web3.Close ();

}

Major ();

`

This code fragment presents a simple method for connecting to the Ethereum network and checking transactions using the Web3 directory. However, this does not address the problem originally mentioned.
