We architect and deploy custom Solidity/Rust smart contracts that power your core product. Our process delivers audit-ready code in 2-4 weeks, integrating battle-tested patterns from OpenZeppelin and Solmate to mitigate reentrancy, overflow, and access control risks.
Cairo StarkNet Security Implementation
Custom Smart Contract Development
Secure, production-ready smart contracts built for your specific business logic and audited for deployment.
From tokenomics to complex DeFi logic, we translate your requirements into gas-efficient, upgradeable on-chain systems.
- Token Standards: Custom
ERC-20,ERC-721,ERC-1155with minting, vesting, and governance modules. - DeFi & DAOs: Automated market makers (
AMMs), staking pools, multi-signature treasuries, and voting systems. - Security First: Every contract undergoes internal review + formal verification tools before third-party audit.
Core Security Implementation Capabilities
We architect and implement Cairo smart contracts with security-first principles, ensuring your StarkNet applications are resilient, auditable, and ready for production. Our focus is on delivering verifiable security outcomes, not just code.
Formal Verification & Prover Integration
We design contracts with formal verification in mind, integrating Cairo's native provability to mathematically guarantee critical logic correctness, eliminating entire classes of runtime vulnerabilities.
Comprehensive Security Audits
Our code undergoes rigorous internal review and is prepared for external audits by leading firms. We implement findings with detailed mitigation reports, ensuring transparency and trust.
Gas Optimization & Cost Security
We specialize in Cairo-specific gas optimization techniques, securing your protocol's economic viability by minimizing L1 settlement costs and preventing operational budget overruns.
Upgradeability & Governance Security
We implement secure, battle-tested upgrade patterns (like proxies with explicit governance) for Cairo, ensuring your protocol can evolve without introducing centralization risks or upgrade exploits.
Reentrancy & State Management
We architect state access patterns and implement checks-effects-interactions in Cairo to eliminate reentrancy risks, a critical defense for DeFi protocols and asset management contracts.
Oracle & Dependency Security
We secure external data integrations with circuit breakers, multi-source validation, and fail-safe mechanisms, protecting your protocol from oracle manipulation and dependency failures.
Business Outcomes of Provably Secure StarkNet Development
Our Cairo-based StarkNet development delivers more than just code. We build secure, scalable infrastructure that translates directly to measurable business advantages for your project.
Reduced Time-to-Market
Accelerate your launch with our battle-tested Cairo development frameworks and reusable security modules. We deliver production-ready StarkNet applications in under 4 weeks, not months.
Unmatched Security Posture
Mitigate catastrophic financial risk. Every contract undergoes formal verification with Cairo's native prover and is audited against our internal security checklist, derived from CertiK and OpenZeppelin standards.
Predictable, Lower Costs
Optimize for L2 economics from day one. Our gas-efficient Cairo patterns and state optimization reduce your protocol's operational costs by up to 90% compared to naive implementations.
Scalability Without Compromise
Handle enterprise-scale transaction volumes. We architect your dApp to leverage StarkNet's validity proofs, enabling thousands of TPS with Ethereum-level security guarantees, eliminating network congestion.
Developer Velocity & Maintainability
Empower your team with clean, documented, and modular Cairo code. We provide comprehensive documentation and architecture diagrams, reducing onboarding time and ensuring long-term maintainability.
Regulatory & Compliance Readiness
Build with institutional adoption in mind. Our implementations include built-in patterns for access control, transaction privacy layers, and audit trails that align with emerging financial compliance frameworks.

Our Security-First Development Methodology
Every Cairo contract we build undergoes a rigorous, multi-layered security process designed to protect your assets and your reputation. We don't just write code; we engineer resilient systems.
Formal Verification & Prover Integration
We integrate formal verification from day one, using Cairo's native provers to mathematically guarantee the correctness of your core business logic, eliminating entire classes of runtime bugs.
Multi-Audit Strategy
Beyond internal review, every project undergoes audits by specialized firms (e.g., Nethermind, ABDK) and public bug bounties on platforms like Immunefi before mainnet deployment.
Gas & Storage Optimization
We architect contracts with Cairo's STARK-proof computational model in mind, optimizing for L1 verification costs and L2 storage to minimize your protocol's operational overhead.
Upgradeability & Emergency Protocols
Implement secure, transparent upgrade patterns (Proxy/Beacon) with multi-sig timelocks and circuit-breaker functions, ensuring you can adapt without introducing centralization risks.
Comprehensive Testing Suite
We deploy a testing pyramid: unit tests for functions, integration tests for contract interactions, and fork-testing against live StarkNet state to simulate real-world conditions.
Post-Deployment Monitoring
Our engagement includes setting up real-time monitoring with Chainscore's analytics, alerting for anomalous transactions, and providing a runbook for incident response.
Custom Blockchain Development
Build and scale custom blockchain networks and Layer 2 solutions tailored to your business logic.
We architect and deploy purpose-built blockchain infrastructure that moves beyond generic frameworks. Our development process delivers production-ready networks in 6-8 weeks, with custom consensus mechanisms and native tokenomics designed for your specific use case.
- Protocol Development: Custom
EVM-compatible chains,Substrate-based parachains, andCosmos SDKapp-chains. - Layer 2 Scaling:
zk-RollupandOptimistic Rollupimplementations for high-throughput applications. - Core Features: Integrated
ERC-20/721standards, multi-sig governance modules, and cross-chain bridges (IBC,LayerZero).
We don't just deploy a chain; we engineer the economic and technical foundation for your ecosystem to thrive, ensuring security and scalability from day one.
Cairo & StarkNet Security Implementation FAQ
Get clarity on our security-first development process, timelines, and guarantees for your StarkNet protocol.
We follow a four-phase security-first methodology integrated from day one: 1) Architecture Threat Modeling to identify risks in the design phase. 2) Secure Cairo Development using established patterns and formal verification principles. 3) Multi-layered Testing including unit, integration, and fuzzing tests. 4) Pre-audit Review where our internal security team performs a full assessment before external audits. This proactive approach has secured over $500M in TVL across our client projects.
