CORE INFRASTRUCTURE
Smart Contract Development
Secure, audited smart contracts that power your Web3 product's core logic.
- Custom Tokenomics: Design and deploy
ERC-20,ERC-721, andERC-1155tokens with vesting, minting controls, and governance hooks. - DeFi Protocols: Develop automated market makers (AMMs), lending pools, staking mechanisms, and yield aggregators.
- Enterprise Logic: Implement complex business rules for asset tokenization, supply chain tracking, and verifiable credentials.
We provide a comprehensive audit package, including unit tests, deployment scripts, and documentation, ensuring your contracts are secure and maintainable for the long term.

COMPREHENSIVE SECURITY REVIEW
What Our AppChain Storage Audit Covers
Our specialized audit goes beyond generic smart contract checks to assess the entire data integrity and availability layer of your application-specific blockchain. We identify vulnerabilities that could lead to data loss, censorship, or chain halts.

EXPERTISE YOU CAN TRUST
Why Audit Your AppChain Storage with Chainscore
AppChain storage is the foundation of your on-chain state. Our specialized audits identify critical vulnerabilities and inefficiencies that generic smart contract reviews miss, ensuring data integrity, performance, and long-term scalability.
01
Specialized AppChain Expertise
Our engineers have deep experience with rollup frameworks (Arbitrum Nitro, OP Stack, zkSync Era) and custom L1s (Cosmos SDK, Substrate). We audit the full stack: state transition logic, data availability layers, and bridge integrations.

02
Proactive Vulnerability Discovery
We go beyond standard checks to find chain-specific risks: state corruption vectors, sequencer failure modes, and cross-chain reorg vulnerabilities. Our reports provide actionable fixes, not just a list of problems.

Strategic Infrastructure Decision
AppChain Storage Audit: Build In-House vs. Partner with Chainscore
A detailed comparison of the time, cost, and risk profile for developing and maintaining a secure, production-grade storage audit solution internally versus leveraging Chainscore's specialized service.
| Key Factor | Build In-House Team | Partner with Chainscore |
|---|---|---|
Time to Production | 6-12+ months | 4-8 weeks |
Upfront Development Cost | $200K - $500K+ | $25K - $75K (Audit & Setup) |
Annual Maintenance & Ops | $150K+ (2-3 FTE) | Optional SLA from $50K/year |
Security & Audit Coverage | High Risk (Custom, Unproven Code) | Low Risk (Pre-Audited, Battle-Tested Frameworks) |
Expertise Required | Specialized R&D in ZK Proofs, Storage Proofs, DA Layers | Leverage Our Dedicated Protocol Security Team |
Protocol Coverage | Limited to 1-2 Chains Initially | Ethereum, Arbitrum, Polygon, zkSync, Base, Optimism |
SLA for Critical Issues | Internal On-Call (Varies) | Guaranteed 4-Hour Response (Enterprise) |
Integration Complexity | High (Custom API, Monitoring, Alerting) | Managed (SDK, Dashboard, Pre-Built Alerts) |
Total 3-Year Cost (Est.) | $750K - $1.5M+ | $150K - $300K |

Frequently Asked Questions
Get clear answers on our specialized audit process for custom blockchain data layers, from timelines to security guarantees.
A comprehensive audit for a custom storage solution typically takes 2-3 weeks from kickoff to final report. This includes a 1-week deep-dive review of architecture and smart contracts, 1 week of active testing and vulnerability analysis, and 3-5 days for report compilation and client review. Complex integrations (e.g., cross-chain bridges, novel consensus mechanisms) may extend this by 1-2 weeks.
