Explore the latest insights, postmortems, and success stories to strengthen your Web3 deployments.
External audits, while important, aren't a perfect solution for Web3 cybersecurity. Recent high-profile hacks on audited projects like Penpie, Ronin, and Euler demonstrate that relying solely on these audits leaves significant vulnerabilities unaddressed. The traditional model needs to evolve beyond just external reviews.
How Lendvest leverages Olympix' proactive security tools to ensure continuous security throughout the development process, rather than relying solely on external auditors, allowing them to save on security costs as we scale without compromising on security itself.
A $27 million hack of Penpie Finance in September 2024, despite prior security audits, highlights the persistent threat of hidden smart contract vulnerabilities. This case study explores how Olympix, a mutation testing tool, could have uncovered the flaw and prevented the loss.
Discover how a critical flaw in Li.Fi's smart contract led to an $11.6M exploit—and how Olympix' static analyzer could have prevented it with early vulnerability identification.
Discover how a simple oversight in smart contract configuration led to a $12M loss for the Ronin Network—and how Olympix's detection system flagged the critical flaw that could have prevented the exploit.

DeFi DAOs control billions in crypto assets through automated governance, but hidden security risks make them prime targets for exploitation. This guide reveals how governance attacks succeed and what developers need to know to build secure DAO systems.
A $44M exploit revealed how function interactions can slip past even top-tier audits. This postmortem shows why analyzing behavior over time is critical to smart contract security.
Security doesn't start at audit, it starts at the pull request. This article breaks down how PR-scoped risk summaries and mutation testing turn every commit into a security checkpoint, directly in your Git workflow.
Web3 coding languages aren’t just about syntax; they’re also about security decisions. This guide breaks down how Solidity, Rust, Move, and Cairo shape your threat model, tooling limits, and exploit exposure. Build smarter by understanding what your language makes easy to get wrong.
Smart contract security best practices won’t protect you. This piece breaks down how real exploits bypass the checklists and how to build security that actually holds up using intent-aware analysis, mutation testing, and state-bound validation. Stop following rules. Start enforcing invariants.
Code coverage tells you what ran. Mutation testing tells you what broke. In this piece, we break down why 100% test coverage means nothing if your tests don’t catch logic failures and how mutation testing exposes the blind spots that lead to real exploits.
Most smart contract security tools look secure but don’t prevent exploits. This guide breaks down what real security tooling should do, why audits aren’t enough, and how Olympix gives developers a full-stack pipeline to catch what others miss. If you’re still relying on scanners and checklists, you’re already behind.
Most teams treat audits like insurance. In reality, they’re just a snapshot. This beginner’s guide breaks down what a Web3 security audit really covers, why so many fail, and how to build real security into your development lifecycle. If you’re launching smart contracts, read this before you trust an audit to protect you.
Dexodus lost $300K after accepting a replayed Chainlink signature. The bug was a missing nonce. Olympix’s detector would’ve flagged it during development and blocked the exploit path entirely.
DeFi aggregators route trades across DEXes to optimize execution, but they also introduce new attack surfaces and trust assumptions. This guide breaks down how they work, where they fail, and what developers must do to integrate them securely.
A practical guide for newcomers to Web3 development. Learn how to set up your environment, write and test your first smart contract, deploy to a testnet, and build a simple dApp interface. Perfect for developers who want to go from zero to on-chain fast, without fluff.
Codify security where exploits begin—Git. This article breaks down how to embed static analysis, mutation testing, and threat modeling directly into your version control workflows. No fluff, just tactical enforcement.
Web3 coding challenges should train for failure, not cleverness. This post shows how to redesign them around real exploits, threat models, and adversarial thinking to actually prepare developers for mainnet.
Most blockchain development frameworks optimize for speed, not security. This post breaks down how popular tools miss critical bugs, why tests pass but code fails, and what builders need to demand from their stack to ship safely.
A head-to-head benchmark of Olympix vs. Slither on the EigenLayer codebase. See how enterprise-grade static analysis stacks up against open-source tools in high-stakes DeFi security.
Most proof markets sacrifice privacy to scale. Fermah encrypts the pipeline with Confidential Proof Dispatch. =Nil; makes external data trustless. Together, they’re building the secure ZK stack DeFi needs next.
Deploying to mainnet means entering a war zone. Most guides on how to learn Web3 coding won’t get you past the front lines. This one does. If you want to think like an attacker, code like a defender, and build contracts that don’t get drained, read this before you write another line.
On August 18, 2023, a vulnerability in the DebtManager contract allowed attackers to drain over $7 million from users on Optimism. The exploit hinged on two things: a fake market contract and a forged permit.
A technical breakdown of what it actually takes to become a Web3 developer. This guide outlines a real Web3 coding roadmap—covering adversarial thinking, EVM mastery, protocol design, testing tools, and security practices every serious builder needs.
Smart contracts, the backbone of Web3 applications, are vulnerable to exploits due to their unchangeable nature. This article examines common vulnerabilities and how to enhance smart contract security.
