How to Audit a Rust Smart Contract on Solana

Auditing Solana smart contracts requires a fundamentally different mindset than Ethereum auditing because Solana's account-based architecture, Rust-native development, and parallel execution model create unique vulnerability classes that don't exist in the EVM world. The most critical difference is that Solana programs receive all accounts as external parameters, making account validation the single most important security consideration—a stark contrast to EVM contracts that have implicit access to their own storage. This guide provides a systematic approach to auditing Solana programs, covering essential tools, vulnerability patterns, and battle-tested methodology for developers entering the Web3 security space.
