🔐 Exploring Vulnerabilities in Rust-Based Smart Contracts: A Curated Repository for Auditors

Are you auditing Rust smart contracts or building secure dApps on platforms like Solana, NEAR, or other Rust-based blockchains?

I've just published a GitHub repository to help you identify, understand, and mitigate common vulnerabilities in Rust smart contracts, tailored for auditors, developers, and researchers.

👉 Repo: Rust Smart Contract Vulnerabilities

---

📦 What's Inside?

This repository is a curated collection of realistic vulnerabilities found in Rust-based contracts, each with:

• 🚨 A detailed explanation of the issue and potential impact
• 🔓 Vulnerable code snippets
• ✅ Secure alternatives and mitigations
• 🔍 Detection methodologies (manual + automated techniques)
• 🌍 Real-world examples (where applicable)

---

💥 Covered Vulnerabilities

Here’s what we cover (with more to come!):

1. Reentrancy (CPI-style) – Solana-style invocation bugs, how they're different from Ethereum
2. Integer Overflow/Underflow – How Rust handles them and when they still go wrong
3. Unchecked Inputs – Missing input validation, dangerous deserialization
4. Oracle Manipulation – Exploiting on-chain/off-chain data feeds
5. Access Control Flaws – Missing role checks, privilege escalation
6. Denial of Service – Crashing logic, resource-based exploits
7. Illicit Fee Collection – Hidden/unauthorized fee redirection
8. Flash Loan Attacks – Temporal exploits in lending protocols
9. Logic Errors – Flawed state transitions, incorrect business logic
10. Randomness Attacks – Predictable seeds and RNG misuse

🎯 Why This Matters (Especially for Auditors)

Smart contract security is evolving beyond Solidity. Rust contracts are increasingly used for mission-critical applications — especially in ecosystems like Solana and NEAR. But:

• The attack surfaces are different
• Tooling is still catching up
• Auditors need specialized training and examples

This repo is meant to fill that gap — helping auditors level up in Rust-specific security patterns.

🧪 Practical Learning with Code + Tests

Each vulnerability has:

• 📘 Markdown-based docs
• 💻 Vulnerable and secure code implementations
• 🧪 Test cases that simulate real attacks

Clone the repo, run the examples, and test your skills against real vulnerabilities.

🙌 Contribute or Collaborate

Security is a community effort. If you’ve found a unique Rust-based vulnerability, have better fixes, or want to improve examples — PRs are welcome!

See CONTRIBUTING.md for details.

⚠️ Disclaimer

This repository is for educational purposes only. The code is intentionally vulnerable and should never be deployed in production.

🧠 Final Thoughts

I built this repo to help security researchers, auditors, and developers write and review safer Rust contracts. As the Rust blockchain ecosystem matures, let’s make sure our security standards do too.

If you're into Rust smart contract auditing, I’d love your feedback, contributions, or ideas for improvement.
