Blockchain security audits
Manual, line-by-line review of smart contract systems across multiple chains with AI audit agents running. Every finding ships with a reproduction and a fix, and we verify the patch before signing off.
Read MoreSecurity for Blockchain and AI financial systems.
We review design, implementation, and operational controls for Web3 protocols and AI agents that hold funds.
The core idea
Blockchain security and agentic payments are now one problem.
Blockchain protocols face constant threat of fund loss, which is why financial systems built on them are crucial to review intensively. The new agentic financial systems run on blockchain too, but they still lack established security principles.
- Smart Contracts
Different Smart Contracts holding funds on different chains, We need to make user funds safe.
- AI Agents
Most tasks are delegated to AI agents now, and no one reviews aganist them.
- Payments
Agentic payments, including x402 and mpp are the future payment system, securing micro-payments for successful projects.
- Tooling
Custom Tools improves productivity, including code review, vunerability detectors, monitoring agents, and more...
Closing the gap on both sides
The contract and the agent transacting with it are one system. We review and build across all of it.
Penetration testing
Simulated real-world attacks against web applications, APIs, blockchain infrastructure, SDKs, and web3 off-chain components.
