Metamask: How to send BNB from my wallet to another wallet using web3?

Sending BNB between Wallets using Web3: A Step-by-Step Guide

Are you tired of sending and receiving Binance Coin (BNB) from one wallet to another, only to be met with a frustrating “insufficient funds” error? You’re not alone. In this article, we’ll walk you through the process of sending BNB between wallets using Web3, specifically focusing on the Metamask wallet integration.

What is Metamask?

Metamask is a popular Ethereum-based wallet that allows users to manage and send/receive Ether (ETH), as well as other cryptocurrencies like BNB. To use Metamask with Web3, you’ll need to set it up in your browser and install the MetaMask extension for your web browser.

Why is this happening?

The “insufficient funds” error occurs when trying to send or receive a certain amount of cryptocurrency from one wallet to another without having enough funds. This can happen due to various reasons, such as:

• Low balance: You may not have sufficient BNB in your wallet.

• Incorrect transaction fee: The transaction fee is too high, causing the sender’s account balance to dwindle before they can send more funds.

How to fix the error

To resolve this issue, follow these step-by-step instructions:

• Ensure you’re using Web3-enabled MetaMask: Make sure you’ve installed and updated your Metamask extension for your web browser.

• Check your BNB balance

  

  : Verify that you have sufficient BNB in your wallet account to cover the gas price of the transaction.

* On Windows: Open Metamask, click on “Tools” > “Account Information”

* On Mac: Click on MetaMask icon (a gear icon) in the browser toolbar

• Set up Web3: In the Metamask extension, go to “Settings” > “Web3” and enable it.

• Verify transaction fee: You can check the transaction fee by going to a specific address’s page on the blockchain explorer (e.g., Etherscan). Look for the “Transaction Fee” column. Ensure this value is reasonable and not too high, as excessive fees will lead to insufficient funds errors.

• Calculate gas price: Calculate the required gas price based on the transaction size, network fees, and block height. You can use online gas price calculators or consult with a blockchain expert if you’re unsure.

• Send BNB: Once you’ve verified your balance and calculated the gas price, you’re ready to send BNB from one wallet to another.

Example code

Here’s an example of how to send BNB using Web3 in JavaScript:

const Metamask = require('metamask-js');

const { Etherscan } = require('@ethersproject/ethers');


// Set up MetaMask instance

const metamask = new Metamask({

  provider: '

});


// Get the wallet's address and BNB balance

const walletAddress = '0x...'; // Replace with your wallet address

const balance = metamask.getBalance(walletAddress);


// Calculate gas price

const transactionSize = 10n;

const networkFee = 10n; // Example fee per transaction

const blockHeight = 10000n;


if (balance < transactionSize) {

  console.error('Insufficient funds!');

} else {

  // Create a new transaction

  const tx = { from: walletAddress, to: '0x...', value: balance - transactionSize };


  // Set the gas price and network fee

  metamask.setTransaction({

    from: walletAddress,

    to: '0x...',

    value: balance - transactionSize,

    gasPrice: blockHeight + networkFee

  });


  // Send the transaction

  metamask.sendTransaction(tx, (error) => {

    if (error) {

      console.error(error);

    } else {

      console.log('Transaction sent successfully!');

    }

  });

}

By following these steps and using the example code above, you should be able to send BNB between wallets using Web3. Remember to always check your balance before sending funds and ensure that your wallet address is correct.
