Solana Program Audits
Ensure the security and performance of your Solana programs with Codeum. Our rigorous audits identify vulnerabilities and optimize your code for seamless performance on the high-speed Solana blockchain.
Why Audit Solana Programs?
Solana processes thousands of transactions per second with sub-second finality, making it one of the fastest blockchains in production. This performance comes from a fundamentally different architecture — programs are written in Rust (or C), compiled to BPF bytecode, and executed in a parallelized runtime. These differences create unique security considerations that EVM-based audits don't address.
Solana's account model, where programs are stateless and data is stored in separate accounts, introduces attack surfaces around account validation, cross-program invocation, and PDA (Program Derived Address) security that require specialized audit expertise.
- Identify vulnerabilities that could lead to exploitation.
- Optimize your program for performance and scalability.
- Ensure compliance with Solana's best practices and standards.
Solana-Specific Security Considerations
Solana's unique architecture introduces security considerations that differ significantly from EVM-based chains:
Account Validation
Unlike Ethereum where contracts own their state, Solana programs must explicitly validate every account passed to them. Missing account validation is the most common and dangerous vulnerability in Solana programs, enabling attackers to substitute malicious accounts.
Cross-Program Invocation (CPI)
Programs calling other programs must carefully validate the target program's identity and handle return values. CPI vulnerabilities have been exploited to drain funds from protocols that trust unauthorized programs.
PDA Security
Program Derived Addresses are used for program-controlled accounts. Improper PDA validation or seed collisions can allow attackers to create unauthorized accounts or access funds controlled by PDAs.
Signer Verification
Programs must verify that the correct signer has authorized each transaction. Missing signer checks are a critical vulnerability that can allow unauthorized users to execute privileged operations.
Arithmetic Overflow
Rust's default overflow checking only applies in debug mode. In release builds (which Solana programs use), arithmetic operations wrap silently unless explicitly checked, creating overflow/underflow risks.
Reentrancy
While Solana's execution model differs from Ethereum, reentrancy is still possible through CPIs. Programs that make external calls before updating state can be exploited through callback attacks.
Our Audit Process
Step 1: Code Analysis
We review your Solana program's architecture and logic to ensure it aligns with its intended functionality.
Step 2: Vulnerability Assessment
Our team performs manual and automated checks to detect vulnerabilities, including reentrancy, overflows, and access control flaws.
Step 3: Final Report
Receive a detailed report with findings, recommendations, and actionable steps to address issues.

Frequently Asked Questions
What programming languages do you audit for Solana?
We audit Solana programs written in Rust (the most common), C, and those built using the Anchor framework. Anchor is the most popular Solana development framework and has its own security patterns that our auditors are experienced with.
How is a Solana audit different from an Ethereum audit?
Solana's account model, parallel execution, and BPF runtime create fundamentally different security considerations. Instead of checking for EVM-specific issues like gas-related attacks, we focus on account validation, CPI security, PDA correctness, and Solana-specific arithmetic risks.
Do you audit Anchor framework programs?
Yes, the majority of Solana programs are built using Anchor. Our auditors are experienced with Anchor's account constraints, error handling patterns, and the specific security considerations that come with using the framework.
Can you audit programs that interact with other Solana protocols?
Yes, we review all cross-program interactions including integrations with Marinade, Jupiter, Raydium, Magic Eden, and other Solana ecosystem protocols. We verify that your program correctly validates and interacts with external programs.
