overview
CORE INFRASTRUCTURE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
- End-to-End Development: From initial specification and
ERC-20/721/1155token design to complex DeFi logic and DAO governance systems. - Security & Auditing: Rigorous internal reviews, formal verification with tools like
SlitherandMythX, and coordination with top-tier external audit firms. - Gas Optimization: Every contract is optimized for minimum execution cost, reducing user transaction fees by up to 40% on average.
- Mainnet Deployment & Verification: We handle the full deployment lifecycle on
EVM-compatible chains (Ethereum,Polygon,Arbitrum) with full source code verification on block explorers.
Deliver a secure, audited, and gas-efficient smart contract suite in as little as 3 weeks, accelerating your path to a trustworthy mainnet launch.

PROVEN FRAMEWORK
Our Atomic Swap Audit Methodology
Our systematic, multi-layered audit process is designed to identify and eliminate critical vulnerabilities before they reach production, ensuring your cross-chain protocol is secure, efficient, and ready for mainnet launch.
01
Architecture & Design Review
We analyze the swap protocol's core logic, tokenomics, and integration points for systemic risks, ensuring a robust foundation resistant to economic attacks and front-running.

Technical & Commercial Questions
Atomic Swap Audit FAQs
Get clear answers on our security audit process, timeline, and deliverables for atomic swap protocols. We audit for DeFi platforms, cross-chain bridges, and institutional trading systems.
We employ a four-phase methodology tailored for cross-chain asset exchange logic:
- Architecture Review: Analysis of swap logic, time-lock mechanisms, and failure states.
- Manual Code Review: Line-by-line inspection of Solidity/Vyper contracts for business logic flaws and gas optimization.
- Automated Testing: Using Slither, MythX, and custom fuzzing tools to detect common vulnerabilities.
- Formal Verification: For critical functions, we use mathematical proofs to verify correctness of hash-lock and secret revelation logic.
Our reports detail vulnerabilities by severity (Critical, High, Medium, Low) with PoC exploits and concrete remediation steps.
