EVM Proxy Pattern Security Audit

Comprehensive security review and hardening of upgradeable smart contracts using Transparent, UUPS, or Beacon proxy patterns to prevent storage collisions and unauthorized upgrades.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

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

We architect and deploy custom smart contracts that form the immutable logic layer of your application. Our process ensures security-first development, gas optimization, and full audit readiness from day one.

Deploy with confidence on EVM, Solana, or Cosmos chains.

  • Custom Logic: Build ERC-20, ERC-721, ERC-1155, or bespoke token standards.
  • DeFi Protocols: Automated market makers, lending/borrowing pools, staking mechanisms.
  • Security: Adherence to OpenZeppelin patterns and formal verification practices.
  • Delivery: Full test suite, deployment scripts, and comprehensive documentation included.

COMPREHENSIVE SECURITY REVIEW

What Our Audit Covers

Our EVM Proxy Pattern Security Audit is a rigorous, multi-layered assessment designed to identify and mitigate critical vulnerabilities before deployment. We deliver actionable reports that give your team and stakeholders confidence in your protocol's security posture.

04

Function Selector Clashing

We identify potential collisions in function selectors between the proxy and implementation that could lead to unintended function execution or blocked upgrades.

05

Integration & Dependencies

We review interactions with external contracts, libraries (like OpenZeppelin), and oracles to ensure the proxy system functions correctly within the broader ecosystem.

06

Gas Optimization & Best Practices

We provide recommendations for optimizing gas usage in delegate calls and ensuring your implementation adheres to established EVM and proxy development standards.

BEYOND STANDARD SECURITY

Why a Specialized Proxy Audit is Critical

Generic smart contract audits miss the unique attack vectors and upgrade complexities inherent to proxy patterns. Our targeted review ensures your upgradeable system's logic, storage, and governance are secure.

01

Storage Collision & Layout Review

We meticulously analyze storage variable ordering and inheritance across implementations to prevent critical data corruption during upgrades, a common failure point in unaudited proxies.

02

Initialization & Reentrancy Vulnerabilities

Our audit enforces secure initialization patterns and identifies reentrancy risks specific to proxy delegatecall mechanics, preventing exploits during contract setup and function execution.

Governance & Upgrade Mechanism Security

We stress-test your admin multi-sigs, timelocks, and upgrade authorization logic to ensure only authorized, non-malicious implementations can be deployed, protecting against governance takeovers.

Smart Contract Development

Secure, gas-optimized smart contracts built to your exact specifications.

We architect and deploy production-grade smart contracts that are secure by design. Every contract undergoes a multi-stage audit process, including automated analysis, manual review, and formal verification for critical logic.

Deliver a market-ready product in 2-4 weeks, not months, with our streamlined development lifecycle.

  • Custom Logic: Tailored Solidity/Rust contracts for DeFi, NFTs, DAOs, and enterprise use cases.
  • Security First: Implementation of OpenZeppelin standards and proprietary security patterns.
  • Gas Optimization: Code reviewed for efficiency, reducing user transaction costs by up to 40%.
  • Full Audit Trail: Comprehensive documentation and test coverage exceeding 95%.

Frequently Asked Questions

Get clear answers on our specialized audit process for upgradeable smart contracts. We address the most common technical and commercial questions from CTOs and lead developers.

We employ a four-phase audit methodology tailored for upgradeable systems: 1) Architecture Review of the proxy pattern (UUPS, Transparent, Beacon) and upgrade governance. 2) Manual Code Review focusing on storage collisions, initialization vulnerabilities, and function selector clashes. 3) Automated Analysis using Slither and custom tools to detect proxy-specific risks. 4) Test Suite & Integration Review to verify upgrade simulations and admin key security. This process is derived from securing $500M+ in TVL across 50+ proxy-based projects.
