League of Lamports focuses on Solana's account system and secure token handling mechanisms. The challenge tests your ability to identify vulnerabilities in account validation and token operations, which are fundamental to Solana's security model.

## Challenge Goals

- Understand Solana's account validation requirements
- Identify improper validation checks in account handling
- Learn about secure token management practices
- Explore attack vectors related to account and lamport manipulation

Originally presented at justCTF 2022, this challenge highlights the importance of proper account validation and token handling in Solana programs. It addresses one of the most common sources of vulnerabilities in Solana smart contracts, making it highly relevant for practical security applications. 

Test your understanding of Solana's account system and secure token handling in this CTF challenge.

## Overview

Understanding Solana's account model is fundamental to developing on the platform. This official documentation piece provides a thorough explanation of accounts, how they differ from traditional blockchain models, and their implications for program development.

Key learning points:
- What an account is in Solana and its attributes (lamports, owner, data, executable).
- The distinction between system-owned accounts and program-owned accounts.
- How data is stored and managed within accounts.
- The concept of rent and its role in account longevity.
- Program Derived Addresses (PDAs) and their significance.

This is a crucial read for grasping how to design and interact with programs on Solana efficiently. 

A deep dive into how Solana stores data using its unique account model. Essential for any developer building on Solana.
