A progressive series of Solana security challenges focusing on different vulnerability types in smart contracts.

Solhana is a series of three progressive challenges that explore different types of vulnerabilities in Solana smart contracts. Each level increases in complexity, introducing new security concepts and exploitation techniques.

Challenge Goals

• Learn about various vulnerability classes in Solana programs
• Understand how different attack vectors can be exploited
• Progress through increasing levels of security complexity
• Develop a comprehensive understanding of Solana security principles

Originally presented at Paradigm CTF, this challenge series offers a structured approach to learning Solana security, making it ideal for developers who want to systematically improve their understanding of smart contract vulnerabilities and exploitation techniques.
