overview
CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
- Security-First Development: Every contract undergoes multi-stage audits including static analysis, manual review, and formal verification.
- Gas Optimization: We reduce transaction costs by up to 40% through efficient storage patterns and bytecode optimization.
- Full Lifecycle Support: From initial spec and
Hardhat/Anchortesting frameworks to deployment and upgrade management via transparent proxy patterns.
Deliver a secure, audited MVP in as little as 2-3 weeks, with a 99.9% uptime SLA for deployed contracts.

EXPERT-LED SECURITY
Our Core Audit Capabilities
Our specialized audit methodology for StarkNet cross-chain bridges combines deep Cairo expertise with battle-tested security practices to protect your protocol and users.
01
Cairo 1.0 & 2.0 Smart Contract Audit
In-depth manual and automated review of your bridge's core logic, focusing on Cairo-specific vulnerabilities, storage handling, and L1-L2 messaging integrity. We ensure your contracts are resilient to reentrancy, arithmetic overflows, and state corruption.

Security Checks
Zero-Knowledge
Circuit Logic Review
02
Cross-Chain Message Protocol Security
Comprehensive analysis of your L1 <> L2 messaging layer (StarkNet Messaging). We verify proof verification, message ordering, finality guarantees, and failure modes to prevent fund loss or state desynchronization.

03
Economic & Incentive Model Review
Stress-testing of your bridge's fee mechanisms, slashing conditions, validator/staker incentives, and liquidity pools. We identify attack vectors like griefing, sandwich attacks, and economic arbitrage that could destabilize the system.
