CORE SERVICE
Smart Contract Development
Secure, audited smart contracts built by experts for production-grade DeFi, NFTs, and Web3 applications.
- Security-First Development: Built on
Solidity 0.8+withOpenZeppelinlibraries and internal audit patterns before formal review. - Protocol Specialization: Custom
ERC-20,ERC-721,ERC-1155, staking systems, DAO governance, and automated market makers (AMMs). - Full Lifecycle Support: From architecture and development through to deployment, verification, and ongoing maintenance on EVM-compatible chains.
We deliver battle-tested contracts that reduce audit cycles by 40% and mitigate critical vulnerabilities before they reach mainnet.
Our engineers have deployed over 200 contracts with a combined TVL exceeding $500M. We translate your business logic into resilient code with 99.9% uptime SLAs and comprehensive documentation.

Test Cases
05
Penetration Testing
Our ethical hackers attempt to exploit the upgrade mechanism, simulating real-world attack vectors like front-running upgrade transactions, privilege escalation, and draining linked treasuries.
06
Final Report & Remediation
Receive a detailed audit report with severity-ranked findings, actionable remediation guidance, and follow-up verification. We provide clear explanations for developers and executive summaries for stakeholders.

BEYOND STANDARD SECURITY
Why Specialized Upgrade Audits Are Critical
Standard smart contract audits are not designed for the unique risks of upgradeable NFT systems. Our specialized process isolates the critical vulnerabilities that can lead to rug pulls, frozen assets, and governance attacks.

CORE SERVICE
Smart Contract Development
Secure, gas-optimized smart contracts built by Web3-native engineers.
We architect and deploy production-grade smart contracts that power your protocol's core logic. Our development process is built on audited security patterns, gas optimization, and comprehensive testing to ensure reliability from day one.
- Token Standards: Custom
ERC-20,ERC-721, andERC-1155implementations with advanced features like vesting, staking, and governance. - DeFi Primitives: Automated Market Makers (AMMs), liquidity pools, lending/borrowing engines, and yield aggregators.
- Security First: Development follows OpenZeppelin standards, with formal verification and pre-audit reviews included.
We deliver battle-tested contracts that reduce audit cycles by 40% and minimize post-launch vulnerabilities.
From initial architecture to mainnet deployment, we manage the full lifecycle. You get production-ready Solidity/Vyper code, detailed documentation, and deployment scripts for Ethereum, Polygon, Arbitrum, and other EVM chains.

Frequently Asked Questions
Get clear answers on our NFT upgrade audit process, timeline, and security guarantees.
We employ a four-phase methodology: 1) Architecture Review: Analyze upgrade logic, inheritance, and integration points. 2) Manual Code Review: In-depth line-by-line analysis by senior auditors focusing on business logic flaws. 3) Automated Testing: Use Slither, MythX, and custom fuzzers to detect common vulnerabilities. 4) Exploit Simulation: Manually simulate attack vectors like reentrancy, front-running, and signature replay. Every audit follows a formal report with CVSS-scored findings and remediation guidance.
