METHODOLOGY
Our Audit Framework
Our structured, multi-layered audit process is designed to provide institutional-grade assurance for your on-chain randomness solution. We go beyond basic code review to assess security, reliability, and economic soundness.
01
Security & Code Review
Comprehensive analysis of smart contract logic, focusing on common vulnerabilities (reentrancy, oracle manipulation) and protocol-specific risks. We use both automated tools (Slither, MythX) and manual review by senior auditors.

Vulnerability Focus
02
Randomness Source Analysis
Deep technical evaluation of your entropy source (VRF, commit-reveal, RANDAO). We assess cryptographic soundness, bias resistance, predictability risks, and liveness guarantees under adversarial conditions.

03
Economic & Game Theory Audit
Stress-testing the protocol's incentive mechanisms and economic security. We model attack vectors like MEV extraction, validator collusion, and stake-slashing scenarios to ensure system robustness.

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts for DeFi, NFTs, and enterprise applications.
We architect, develop, and audit custom Solidity and Rust smart contracts that form the backbone of your Web3 product. Our focus is on security-first development, leveraging battle-tested patterns from OpenZeppelin and formal verification to mitigate risks before deployment.
- End-to-End Development: From token standards (
ERC-20,ERC-721,ERC-1155) to complex DeFi primitives like AMMs and lending pools. - Security & Audits: Rigorous internal review, automated testing with
Hardhat/Foundry, and preparation for third-party audits. - Gas Optimization: Code-level optimizations to reduce user transaction costs by 15-40% on average.
- Mainnet Deployment: Full support for deployment, verification, and initial monitoring on Ethereum, Polygon, Arbitrum, and other EVM chains.
We deliver contracts you can trust, built to handle real volume and secure real assets. Our process ensures a production-ready MVP in as little as 3 weeks.

Frequently Asked Questions
Get clear answers on our audit methodology, timeline, and security guarantees for your VRF or randomness oracle protocol.
We employ a four-phase methodology tailored for VRF and randomness systems: 1) Architecture Review of the cryptographic design and economic incentives. 2) Manual Code Review focusing on entropy sources, VRF implementation, and oracle node logic. 3) Automated Analysis using Slither, Foundry, and custom fuzzing tools to test edge cases and distribution fairness. 4) Formal Verification of critical cryptographic components where applicable. This process has secured over $500M in TVL across 30+ oracle projects.
