# About This Course

LearnEVM.com is designed to be a mix of two things:

1. A reference manual you can return to when dealing with the gritty details of each chapter, and:
2. A linear course, with its content sorted such that you can read from beginning to end in a progressive manner.

# Prerequisites

To get the most out of this course, you should be familiar with:

• What Ethereum is and why we can run code on it.
• Generally what the fields for a transaction are.
• How transactions make it from wallet to chain.
• A rough mental model of how contracts run on-chain.
• Writing smart contracts in Solidity or a similar language.
• A basic idea of how CPUs run low-level instructions.

# Learning Objectives

After going through this course, you will:

• Understand what it means for the EVM to be a virtual machine.
• Understand what the EVM’s execution environment is and how to work with it.
• Have a deep understanding of how contract deployment works, and how Solidity deployment patterns work under the hood.
• Understand how function calls work, and the differences between the CALL variants.
• Understand the anatomy of ABI encoded function calls.
• The inner workings of common Solidity idioms.
• The inner workings of Solidity data structures and their security implications.
• Common Solidity gas optimizations based on their compiled SLOAD/SSTORE opcodes.
• How to write smart contracts in raw opcodes 😎

Each chapter has its own collection of intricate details; the above list only describes concepts at high level.

# Exercises

In an ideal world, each chapter and section would have self-paced checkpoints and exercises. However, our audits team is also busy with audits, so we're releasing the first version without exercises in the interest of launching sooner than later.

# Incremental

Also in the interest of launching sooner than later, you'll find many chapters are still (coming soon). We will be releasing new chapters periodically; follow us on Twitter to stay updated.
