Send 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 faced with a frustrating “insufficient funds” error? You are not alone in this. In this article, we will walk you through the process of sending BNB between wallets using Web3, focusing specifically 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 such as BNB. To use Metamask with Web3, you need to set it up in your browser and install the MetaMask extension for your web browser.
Why does this happen?
The “insufficient funds” error occurs when you try to send or receive a certain amount of cryptocurrency from one wallet to another without having sufficient funds. This can have several reasons, such as:
- Low Balance: You may not have enough BNB in your wallet.
- Incorrect Transaction Fee
: The transaction fee is too high, causing the sender’s account balance to be reduced before they can send more money.
How to fix the error
To resolve this issue, please follow these step-by-step instructions:
- Make sure you are using Web3-enabled MetaMask: Make sure you have the Metamask extension installed and updated for your web browser.
- Check your BNB balance: Make sure you have enough BNB in your wallet account to cover the gas fee of the transaction.
- On Windows: Open Metamask and click Tools > Account Information
- On Mac: Click the MetaMask icon (a gear icon) in the browser toolbar
- Configure Web3: In the Metamask extension, go to Settings > Web3 and enable it.
- Check Transaction Fee: You can check the transaction fee by going to a specific address’s page in the blockchain explorer (e.g. Etherscan). Look for the “Transaction Fee” column. Make sure this value is reasonable and not too high, as excessive charges 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 a blockchain expert if you are unsure.
- Send BNB: Once you have verified your balance and calculated the gas price, you can send BNB from one wallet to another.
Sample code
Here is an example of how to send BNB using Web3 in JavaScript:
`javascript
constant Metamask = require('metamask-js');
const { Etherscan } = require('@ethersproject/ethers');
// Set up the MetaMask instance
constant metamask = new Metamask({
Provider: '
});
// Get the wallet address and BNB balance
constant walletAddress = '0x...'; // Replace with your wallet address
const balance = metamask.getBalance(walletAddress);
// Calculate gas price
constant transactionSize = 10n;
constant networkFee = 10n; // Example transaction fee
constant blockHeight = 10000n;
if (balance < transactionSize) {
console.error('Insufficient resources!');
} else {
// Create new transaction
const tx = { from: walletAddress, to: '0x...', value: balance - transactionSize };
// Set gas price and network fee
metamask.setTransaction({
from: walletAddress,
to: '0x...',
Value: Balance - transactionSize,
Gas Price: blockHeight + networkFee
});
// Send transaction
metamask.sendTransaction(tx, (Error) => {
if (error) {
console.error(error);
} else {
console.log('Transaction sent successfully!');
}
});
}
“
If you follow these steps and use the example code above, you should be able to send BNB between wallets using Web3. Always remember to check your account balance before sending funds and make sure your wallet address is correct.
