Lesson 3: Ethereum Transactions

Ethereum Transactions

In this lesson, we will delve deeper into the world of Ethereum transactions, including sending and receiving Ether, gas and transaction fees, and interacting with smart contracts.

A. Sending and Receiving Ether

One of the most basic uses of a transaction on the Ethereum network is sending and receiving Ether (ETH). This can be done using a variety of tools, such as a wallet or an online service. It’s important to double check the recipient address and the amount before sending a transaction, as transactions on the Ethereum network are irreversible.

B. Gas and Transaction Fees

In order for a transaction to be processed on the Ethereum network, a small fee in the form of gas is required. The amount of gas required for a transaction varies depending on the complexity of the transaction. Users must pay for this gas in Ether (ETH). It’s important to note that the transaction fee is separate from the amount being sent and it’s used to compensate the network’s miner for their work.

C. Smart Contracts

Another important aspect of Ethereum transactions is the ability to interact with smart contracts. Smart contracts are self-executing contracts with the terms of the agreement directly written into lines of code. These contracts can be used for a wide variety of applications, such as creating a decentralized exchange or a crowdfunding platform. Interacting with a smart contract typically requires a higher amount of gas as compared to a simple Ether transfer.


Ethereum transactions are a powerful tool, allowing for the transfer of value in the form of Ether, as well as the ability to interact with smart contracts. Understanding the basics of gas and transaction fees, as well as the process for sending and receiving Ether, is crucial for anyone looking to use the Ethereum network.
