Upgradeable Proxy Contract Verification

Specialized formal verification for Transparent and UUPS proxy patterns. We mathematically prove storage layout preservation, initialization safety, and access control integrity to eliminate upgrade risks.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

Secure, audited smart contracts built to your exact specifications.

We architect and deploy production-ready smart contracts that are secure by design. Our development process integrates formal verification and automated testing from day one, ensuring your core business logic is resilient against exploits.

Deploy with confidence. Every contract undergoes a multi-layered security review before reaching mainnet.

  • Custom Logic: Tailored Solidity/Rust development for DeFi protocols, NFTs (ERC-721A), tokens (ERC-20), and DAOs.
  • Security First: Built with OpenZeppelin standards and subjected to internal + external audits.
  • Full Lifecycle: From specification and development to deployment, verification, and ongoing upgrade management.

COMPREHENSIVE AUDIT COVERAGE

What We Verify

Our verification process goes beyond basic functionality to ensure your upgradeable proxy system is secure, efficient, and future-proof. We deliver actionable reports that give your team and users confidence.

01

Proxy Storage Layout

We verify that the storage layout between your proxy and implementation contracts is compatible, preventing critical data corruption during upgrades. This includes struct and mapping alignment checks.

02

Initialization & Constructor Logic

We audit the initialize function and constructor patterns to prevent front-running and re-initialization attacks, ensuring your contract state is set securely and only once.

03

Upgrade Governance & Access Control

We verify the upgrade authorization mechanism (e.g., Timelock, Multi-sig, DAO) for proper role-based access control, preventing unauthorized implementation swaps.

Function Selector Clashes

We perform collision analysis to ensure no function selectors in the new implementation conflict with the proxy's fallback or reserved functions, preventing unintended behavior.

Gas Optimization & Cost Analysis

We benchmark and optimize the gas costs of your upgrade path and delegatecall operations, ensuring cost-efficient upgrades for you and your users.

Integration & Dependency Review

We verify compatibility with external dependencies (oracles, tokens, other contracts) and test integration points to ensure the upgrade doesn't break your ecosystem.

THE INDUSTRY STANDARD

Why Formal Verification for Proxies

Upgradeable proxies introduce unique attack vectors that standard audits miss. Our formal verification mathematically proves your proxy logic is secure, preventing catastrophic failures and protecting user funds.

Choosing the Right Security Path

Verification vs. Traditional Audit

Upgradeable proxy contracts require specialized security approaches. This table compares the scope, process, and outcomes of our dedicated verification service against a standard smart contract audit.

CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3 experts to power your decentralized application.

We architect and deploy custom smart contracts for DeFi, NFTs, DAOs, and enterprise applications. Our team delivers audit-ready code in Solidity, Rust, or Vyper, leveraging battle-tested patterns from OpenZeppelin and our own extensive library.

From concept to mainnet, we ensure your logic is secure, gas-optimized, and future-proof.

  • Security-First Development: Every line undergoes internal review against common vulnerabilities before formal audits.
  • Full-Stack Integration: Contracts are delivered with comprehensive test suites, deployment scripts, and frontend SDKs.
  • Measurable Outcomes: Typical projects achieve audit completion in 3-4 weeks and mainnet deployment within 2 weeks post-audit.

Frequently Asked Questions

Get clear answers on our process, security, and deliverables for verifying your upgradeable smart contracts.

For a standard proxy implementation (e.g., Transparent or UUPS), verification typically takes 3-5 business days after receiving the complete source code and deployment details. Complex systems with multiple proxies, custom storage layouts, or inherited logic can extend this to 7-10 days. We provide a detailed project plan after the initial audit.
