We architect and deploy custom smart contracts on EVM-compatible chains (Ethereum, Polygon, Arbitrum) and Solana. Our code is built for enterprise-grade security and gas efficiency.
Upgradable Contract Proxy Pattern Security Testing
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
- Full Lifecycle Development: From initial design and
Solidity 0.8+/Rustcoding to comprehensive testing and mainnet deployment. - Security-First: All contracts undergo internal audits and are built with
OpenZeppelinstandards. We prepare for formal third-party audits. - Key Deliverables:
ERC-20,ERC-721,ERC-1155tokens, DeFi protocols (DEX/AMM, staking), DAO governance, and custom business logic.
We deliver auditable, maintainable code that reduces your time-to-market and mitigates critical financial risks.
Our Proxy Pattern Testing Methodology
We deliver a systematic, multi-layered audit designed to identify critical vulnerabilities in your proxy upgrade architecture, ensuring your smart contracts remain secure and functional through every iteration.
Architecture & Initialization Review
We analyze your proxy pattern choice (Transparent, UUPS, Beacon) and verify correct initialization to prevent storage collisions and front-running attacks. This includes a full review of constructor logic and initializer functions.
Upgrade Path & Governance Simulation
We simulate the entire upgrade lifecycle, testing timelocks, multi-sig governance, and emergency pause mechanisms to ensure only authorized, non-breaking upgrades can be deployed.
Storage Layout Verification
We perform automated and manual checks to guarantee storage variable alignment between proxy and implementation versions, preventing critical state corruption during upgrades.
Function Selector Clash Analysis
We audit all function selectors in the proxy and implementation to prevent malicious collisions that could bypass admin functions or cause unintended behavior.
Integration & Fallback Testing
We test interactions with external contracts, delegate calls, and fallback/receive functions to ensure seamless operation post-upgrade and maintain composability.
Final Security Report & Remediation
You receive a detailed report with CVSS-scored vulnerabilities, proof-of-concept exploits, and actionable remediation guidance, followed by re-audit verification.

Why Specialized Proxy Testing is Critical
Standard smart contract audits miss the unique attack vectors introduced by proxy patterns. Our targeted testing methodology isolates and validates the critical interactions between your logic, storage, and upgrade mechanisms.
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
We architect, develop, and audit custom Solidity and Rust smart contracts that form the backbone of your Web3 application. Our focus is on security-first development, leveraging battle-tested patterns from OpenZeppelin and formal verification tools to mitigate risk.
Deliver a secure, audited, and gas-optimized contract suite in as little as 2-4 weeks for an MVP.
- Token Systems: Custom
ERC-20,ERC-721, andERC-1155implementations with advanced features like vesting, minting controls, and governance hooks. - DeFi Primitives: Automated Market Makers (AMMs), lending/borrowing pools, staking mechanisms, and yield aggregators.
- Enterprise Logic: Multi-signature wallets, access control systems, and upgradeable proxy patterns for future-proofing.
- Full Audit Trail: Every contract undergoes internal review and is prepared for third-party audits from firms like
CertiKorTrail of Bits.

Frequently Asked Questions
Get clear answers on our methodology, timeline, and security guarantees for proxy pattern testing.
Our testing follows a systematic, three-phase approach. Phase 1: Architecture Review assesses the upgrade mechanism (Transparent, UUPS, Beacon), admin privileges, and initialization logic. Phase 2: Automated Analysis uses Slither and custom tooling to detect storage collisions, selector clashing, and function visibility issues. Phase 3: Manual Review focuses on logic consistency, access control bypasses, and integration risks with external contracts. We deliver a detailed report with CVSS-scored vulnerabilities and remediation guidance.
