Smart Contract Security Platform

Find and resolve smart contract vulnerabilities before the audit

Olympix works alongside your team as they write code, catching vulnerabilities and gaps in your tests on every change and proving each finding with a working exploit, so your auditors start from cleaner code.

Web3 security: high stakes,
‍unmet needs.

90%

of exploited smart contracts were audited

Every audit reviews its own scope, in the time it has. Exploits tend to land where audited scopes meet the rest of the system, in code no single review looked at as a whole.

Web2 made proactive security standard

In Web2, security checks run inside the development process, on every change. In Web3, most teams still lean on audits at the end of each release, so the bulk of the security work starts once the code is already written.

Olympix brings it to smart contracts

Olympix automates the two sides of proactive security during development: detection, finding audit-level issues and what audits miss, and coverage, making sure your code is tested adversarially, not just line by line.

Audits identify issues and Olympix prevents them.

Traditional audits are essential but limited

They are periodic and reactive, addressing vulnerabilities only after the code is developed. This leaves significant gaps where issues can arise between audits or go undetected.

With DeFi’s fast-paced nature,

it’s critical to build robust security into the development process. Proactive tools like Olympix enable organizations to continuously identify and resolve vulnerabilities, ensuring that every release meets the highest security standards.

The platform

Five tools in your workflow, from first commit to release.

Olympix runs in the IDE and in CI on every change, so your team finds and fixes issues before code reaches the auditors.

01Static Analysis

Flags known vulnerability patterns with 80+ proprietary detectors. Runs on uncommitted changes, so issues are fixed before a pull request is opened.

02Test Generation

Writes unit tests for your contracts automatically, so coverage goes up without your team writing them by hand.

03Mutation Testing

Makes small, deliberate changes to your code and counts how many your tests catch. For each change they miss, it writes the test that would have caught it. Runs on Solidity and on Solana programs written in Rust with Anchor.

04BugScout

Works like an attacker with a playbook. It maps every feasible path through your code, runs the known attack that fits each risky one, such as vault share inflation or AMM manipulation, and turns every attack that lands into a Forge test. You also see exactly which paths were tested.

05BugPoCer

Works out the rules your contracts depend on but never state, then tries to break them. Every finding comes back as a working proof-of-concept exploit, and you can point it at the vulnerability classes you care about most. Supports Solidity, Rust and Cairo.

Reentrancy in withdraw()
The external call runs before the balance update, so withdraw() can be re-entered and drained.
MEDIUMVault.sol:145
Missing access control
Anyone can call setFeeRecipient() and redirect fees to their own address.

Security Perimeter

Set the bar once.
See every contract against it.

With Security Perimeter, you pick the thresholds your team ships against, such as zero high and medium findings, a minimum branch coverage and a minimum mutation score. Olympix measures your entire codebase against them in real time, and checks every new commit the moment it lands, instead of leaving you with snapshots from separate tools and audits.
