This tutorial provides hands-on code examples for sending ETH transactions. We'll walk through the entire process with detailed explanations of each step, including:
- Retrieving wallet public keys
- Obtaining nonce values
- Setting gas price and gas limit parameters
- Executing ETH transfer transactions using these parameters
Core Components of ETH Transactions
1. Wallet Public Keys
Every Ethereum transaction requires a valid wallet address. We'll demonstrate how to:
- Generate a new wallet
- Import an existing wallet
- Extract the public key from a wallet
2. Nonce Values Explained
The nonce is a critical security feature that prevents transaction replay attacks. Learn:
- What nonce values represent
- How to retrieve the current nonce
- Why nonce management is essential
3. Gas Parameters Optimization
Proper gas settings ensure your transactions get processed efficiently:
- Gas price: The amount you're willing to pay per unit of gas
- Gas limit: The maximum gas you're willing to spend
- Current network gas price benchmarks
Transaction Execution Process
Step-by-Step Code Implementation
// Sample code for ETH transaction
const transaction = {
to: '0xRecipientAddress',
value: web3.utils.toWei('1', 'ether'),
gas: 21000,
gasPrice: web3.utils.toWei('50', 'gwei'),
nonce: await web3.eth.getTransactionCount('0xSenderAddress')

FAQ Section
How long does an ETH transaction typically take?
Transaction times vary based on network congestion and gas price. Standard transactions usually confirm within 2-5 minutes when using appropriate gas prices.
What happens if I set the gas limit too low?
If your transaction requires more gas than the specified limit, it will fail and consume all the gas up to the limit without completing the operation.
Can I cancel a pending ETH transaction?
Yes, you can replace a pending transaction by sending another transaction with the same nonce but higher gas price. Alternatively, you can send a transaction with zero value to your own address.
What's the difference between gas price and gas limit?
Gas price determines how much you pay per unit of computation, while gas limit sets the maximum amount of computation you're willing to pay for in a single transaction.
How do I estimate the right gas price?
Use tools like ETH Gas Station or your wallet's built-in estimators. Current network conditions should guide your gas price selection.
