Comprehensive reviews for blockchain infrastructure - delivered by security experts who understand the critical nature of consensus and node operations.
Cantina provides specialized security reviews for Layer 1 and Layer 2 blockchain infrastructure. From validator operations and RPC endpoints to block explorers and bridge systems, our experts identify vulnerabilities that could compromise network integrity. Blockchain teams choose Cantina for our deep understanding of consensus mechanisms, node infrastructure, and the unique security challenges facing blockchain networks.
Whether you're launching a new chain, implementing rollup technology, or upgrading validator infrastructure, our reviewers ensure your network maintains security while achieving scalability and decentralization goals.
We focus on blockchain infrastructure attack surfaces:
Reviews can be scoped for specific applications, microservices, monoliths, or third-party SaaS integrations - whether web-based, mobile, or hybrid.
Security issues in traditional systems remain one of the leading causes of loss in Web3. From dashboards and admin panels to APIs and cloud services - your off-chain infrastructure is just as critical as your contracts.
Partner with Cantina to secure the full picture.
It's a structured security assessment of traditional blockchain infrastructure—such as validator nodes, RPC endpoints, block explorers, or bridge systems. The goal is to identify vulnerabilities that could compromise network security or consensus.
Cantina uses a decentralized model. You're matched directly with elite freelance security researchers who understand blockchain infrastructure - no bloated overhead, no junior staffing. Reviews are scoped, executed, and delivered through a secure, transparent platform.
All Cantina reviewers are vetted through peer-reviewed competitions and real-world assessments. For L1/L2 projects, we match you with researchers who have specific experience in consensus systems and network security.
Yes. If your chain involves both infrastructure and smart contract components (native contracts, bridge contracts), we can bundle both into a coordinated engagement.
Yes. You'll receive a PDF report with detailed findings, severity levels, network impact analysis, and remediation suggestions. We also offer fix validation as an optional follow-up.
