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.
Upgradeable Proxy Contract Verification
Smart Contract Development
Secure, audited smart contracts built to your exact specifications.
Deploy with confidence. Every contract undergoes a multi-layered security review before reaching mainnet.
- Custom Logic: Tailored
Solidity/Rustdevelopment for DeFi protocols, NFTs (ERC-721A), tokens (ERC-20), and DAOs. - Security First: Built with
OpenZeppelinstandards and subjected to internal + external audits. - Full Lifecycle: From specification and development to deployment, verification, and ongoing upgrade management.
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.
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.
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.
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.
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.
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.
| Security Aspect | Traditional Smart Contract Audit | Chainscore Proxy Verification |
|---|---|---|
Focus | General code vulnerabilities | Proxy-specific risks & upgrade safety |
Key Deliverable | Vulnerability report | Verified safe upgrade path & deployment package |
Time to Secure | 2-4 weeks | 1-2 weeks |
Coverage | Logic contract only | Full system: proxy, admin, logic, & migration |
Prevents | Common exploits (reentrancy, overflow) | Storage collisions, function clashing, initialization attacks |
Post-Deployment Support | Limited | Continuous monitoring & upgrade validation |
Ideal For | New, immutable contracts | Production systems requiring future upgrades |
Typical Investment | $15K - $50K+ | $8K - $25K |
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.
