overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built to your exact specifications.

We architect and deploy custom smart contracts that power your decentralized application's core logic. Our development process ensures security-first design, gas optimization, and comprehensive audit readiness from day one.

  • Token Systems: Custom ERC-20, ERC-721, and ERC-1155 implementations with advanced features like vesting, staking, and governance.
  • DeFi Protocols: Automated Market Makers (AMMs), lending/borrowing pools, yield aggregators, and derivative contracts.
  • Enterprise Logic: Multi-signature wallets, access control systems, and verifiable on-chain workflows for business processes.
  • Security & Auditing: Built with OpenZeppelin standards, undergo rigorous internal review, and are prepared for third-party audits.

We deliver battle-tested contracts that execute as intended, protecting your assets and your users' trust.

TAILORED FOR STARKNET

Our Cairo-Specific Audit Methodology

We apply a specialized, multi-layered approach designed specifically for the Cairo language and StarkNet's unique architecture, ensuring your account abstraction system is secure, efficient, and production-ready.

01

Architecture & Logic Review

Deep analysis of your account system's design patterns, entrypoint flows, and integration with StarkNet's sequencer and prover. We identify systemic risks before line-by-line review.

02

Cairo-Specific Vulnerability Hunting

Targeted checks for Cairo 1.0 pitfalls: storage variable collisions, unsafe low-level calls, reentrancy in the async model, and arithmetic over/underflows specific to felt252.

03

Account Abstraction Compliance

Verification against ERC-4337 and StarkNet's native AA standards. We validate paymaster integration, signature validation, user operation bundling, and fee delegation logic.

04

Gas Optimization & Cost Analysis

Benchmarking L1→L2 message costs and storage writes. We recommend Cairo patterns to minimize prover workload and reduce user transaction fees by up to 40%.

05

Formal Verification Readiness

Prepare your codebase for mathematical proof systems. We structure invariants and pre/post-conditions to facilitate future formal verification, a key StarkNet advantage.

06

Remediation & Best Practices Guide

Receive a prioritized action plan with fix recommendations and a custom Cairo/StarkNet security checklist to harden your development lifecycle against future vulnerabilities.

EXPERTISE MATTERS

Why Choose a Specialized StarkNet Audit

Generic audits miss the unique risks of Cairo and StarkNet's architecture. Our specialized focus delivers security that directly protects your assets and reputation.

01

Cairo-Specific Vulnerability Detection

We uncover logic flaws unique to the Cairo VM, like storage pointer manipulation, non-deterministic jumps, and StarkNet-specific reentrancy patterns that generic tools miss.
