CORE ENGINEERING
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
- Custom Logic: DeFi protocols, NFT marketplaces, DAO governance, and enterprise tokenization.
- Security First: Multi-signature deployment, upgradeable proxy patterns, and automated vulnerability scanning.
- Time-to-Market: Go from spec to mainnet in as little as 4 weeks with our proven development lifecycle.
We guarantee zero critical vulnerabilities in our audited code. Your contract's integrity is our primary KPI.

PROTOCOL RESILIENCE
Comprehensive Upgrade Safety Analysis
Our audit goes beyond standard vulnerability checks to deliver a holistic safety assessment for your protocol's upgrade path, ensuring business continuity and user trust.
01
State & Storage Migration Analysis
We map and validate all state variable changes, inheritance shifts, and storage layout impacts to prevent data corruption or loss during the upgrade process.

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by experts for your Web3 application.
We architect and deploy custom smart contracts that form the secure, immutable backbone of your dApp. Our development process is built on audited code patterns and gas optimization from day one, ensuring reliability and cost-efficiency at scale.
From initial concept to mainnet deployment, we handle the full lifecycle so your team can focus on product and growth.
- Protocol Development: Custom logic for DeFi (DEX, lending, staking), NFTs (ERC-721A, ERC-1155), and DAOs.
- Security First: Development with
OpenZeppelinlibraries, followed by third-party audits from firms like CertiK or Quantstamp. - Gas Optimization: Expert tuning to reduce user transaction costs by 20-40% on average.
- Full Deployment: End-to-end support from testnet (
Sepolia,Holesky) to mainnet (Ethereum,Polygon,Base).
The Infrastructure Advantage
Manual Review vs. Chainscore Auditor
Comparing the resource-intensive, high-risk process of manual smart contract upgrade reviews with our automated, enterprise-grade security service.
| Audit Factor | Manual In-House Review | Chainscore Auditor |
|---|---|---|
Time to First Report | 2-4 weeks | < 48 hours |
Coverage (OWASP Top 10, SWC Registry) | Partial (team-dependent) | Comprehensive (automated + expert) |
False Positive Rate | High (manual triage) | < 5% (ML-powered filtering) |
Expertise Required | Senior Solidity Dev + Security Lead | None (managed service) |
Audit Cost (per upgrade) | $10K-$50K+ (internal labor) | From $5K (predictable pricing) |
Security Guarantee | None (liability on your team) | Financial warranty (terms apply) |
Integration (CI/CD, Foundry, Hardhat) | Manual process | Native plugins & API |
Historical Diff Analysis | Manual git review | Automated version tracking |
Critical Issue Response SLA | None (depends on team) | < 4 hours (Enterprise tier) |

Smart Contract Upgrade Audit FAQs
Get clear answers on our process, timeline, and security guarantees for upgrading your protocol's core logic.
We employ a three-phase audit methodology focused on upgrade safety: 1) Architectural Review of the upgrade pattern (UUPS, Beacon, Diamond) and governance flow. 2) Differential Analysis comparing new logic against the legacy system for unintended side effects and state corruption risks. 3) Targeted Exploit Simulation testing upgrade mechanisms, admin key compromise, and time-lock bypasses. This process is based on our experience securing over $500M+ in protocol TVL across 50+ upgrade projects.
