Smart Contract Security Platform

Find and resolve smart contract vulnerabilities before the audit

Static analysis, test generation, mutation testing, BugScout and BugPoCer run on every change, so your team fixes issues in-house and your auditors start from cleaner code.

Web3 security: high stakes, unmet needs.

90%

of exploited smart contracts were audited

Decentralized finance (DeFi) has unleashed innovation but introduced unprecedented security risks. The majority of DeFi exploits, totaling millions in losses, result from smart contract vulnerabilities.

DeFi exploits come from smart contract vulnerabilities

In Web2, proactive security tools are a foundational part of any mature security strategy. In Web3, adoption of these proactive measures has lagged behind, not because organizations aren’t aware of the need, but because the tools simply haven’t been robust enough to meet the unique demands of smart contract security. That ends with Olympix.

Olympix is the future of smart contract security

Decentralized finance (DeFi) has unleashed innovation but introduced unprecedented security risks. The majority of DeFi exploits, totaling millions in losses, result from smart contract vulnerabilities.

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 as code is written, in the IDE and on every pull request.

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 reads the signals that mark a code path as risky, then runs the known attack that fits, such as vault share inflation, arbitrary delegatecall or AMM manipulation, on every release.

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()

External call happens before the balance update, so withdraw() can be re-entered and drained.

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.
