Solana Smart Contract Audit in 2025

4 min read

The Solana smart contract audit process has become a must-have step for developers launching decentralized applications on the Solana blockchain. With its high-speed transaction capabilities and low costs, Solana has attracted DeFi protocols, NFT platforms, and cross-chain bridges. However, the same performance advantages come with unique vulnerabilities that require specialized security reviews. FailSafe provides tailored auditing, monitoring, and compliance solutions to ensure Solana projects are secure before and after launch.

What is a Solana Smart Contract Audit?

A Solana smart contract audit is a comprehensive security review of on-chain programs written for Solana, typically in Rust. The process identifies vulnerabilities, logical flaws, and inefficiencies that could lead to exploits or financial loss. It involves both manual code review and automated analysis, focusing on access control, data validation, memory safety, and secure cross-program invocations.

FailSafe’s smart contract audits go beyond static analysis, incorporating simulation-based attack modeling and performance testing tailored to Solana’s runtime.

Common Vulnerabilities in Solana Smart Contracts

Access Control Weaknesses

Improper validation of signer accounts can allow unauthorized entities to execute privileged instructions.

Arithmetic and Overflow Errors

Unchecked calculations may lead to unexpected values or bypass of critical logic checks.

Unsafe Cross-Program Calls

One vulnerable program can compromise others it interacts with, making secure CPI handling essential.

Dependency Risks

External Rust crates may contain unpatched vulnerabilities, creating a supply chain attack surface.

Solana Smart Contract Audit Process

Scope Definition and Documentation

Identify the intended behavior, architecture, dependencies, and integrations before starting the review.

Manual Code Review

Line-by-line inspection to detect logic errors, improper account handling, and unsafe instructions.

Automated Vulnerability Scanning

Use of security tools like Cargo Audit and Clippy to detect common coding issues.

Exploit Simulation

Testing the contract against real-world attack scenarios, including re-entrancy and transaction ordering risks.

Reporting and Remediation

A detailed report outlines issues, severity levels, and recommended fixes. FailSafe supports re-audits to confirm remediation.

Why Solana Smart Contract Audits Matter

  • Improve contract reliability and reduce post-deployment incidents
  • Prevent costly exploits that could damage project credibility
  • Increase user and investor trust through third-party verification
  • Meet compliance and risk management standards

FailSafe strengthens audit outcomes with services like transaction monitoring for real-time on-chain response and radar for KYT and wallet screening.

FailSafe’s Security Advantage for Solana Projects

  • Integrated Risk Management: Combining audits with live monitoring to catch threats as they happen
  • Proactive Vulnerability Testing: Using penetration testing to stress-test systems before deployment
  • Compliance Support: Adapting to evolving blockchain regulations and implementing KYT procedures to ensure adherence
