PROTECTED INTELLIGENCE
Business Outcomes with EVM Confidential Contracts
Move beyond public ledgers. Our confidential contract development delivers tangible advantages for fintechs and enterprises, securing your competitive edge and operational data.
01
Protect Proprietary Logic
Deploy DeFi strategies, trading algorithms, and settlement logic on-chain without exposing your intellectual property to competitors. We implement confidential state and computation using advanced cryptographic primitives like zk-SNARKs and secure enclaves.

Secure Sensitive Transactions
Enable private OTC trades, confidential payroll, and institutional-grade settlement where transaction amounts and counterparties remain hidden on the public blockchain. Our contracts ensure only authorized parties can decrypt sensitive data.

Technical Comparison
Confidential Contracts vs. Traditional Smart Contracts
A detailed breakdown of how EVM Confidential Contracts, powered by technologies like zk-SNARKs and secure enclaves, fundamentally differ from public smart contracts in security, functionality, and compliance.
| Feature / Attribute | Traditional Smart Contracts | Chainscore Confidential Contracts |
|---|---|---|
Data Visibility | Fully public on-chain | Encrypted state & private computation |
Regulatory Compliance | Challenging (GDPR, CCPA) | Built-in for sensitive data |
Development Complexity | Standard Solidity/Vyper | Advanced (ZK circuits, TEEs) |
Time to Market (Typical) | 4-8 weeks | 8-16 weeks (with audit) |
Security Audit Criticality | High (public attack surface) | Critical (novel cryptographic trust) |
Ideal Use Cases | Public DEXs, NFTs, DAOs | Private DeFi, Enterprise B2B, Healthcare |
Transaction Cost | Standard gas fees | Gas fees + compute overhead for privacy |
Team Expertise Required | Solidity, Web3.js | Cryptography, Zero-Knowledge Proofs |
Chainscore Development Cost | $50K - $150K | $150K - $500K+ |

Frequently Asked Questions
Get clear answers on our development process, security, timelines, and support for your confidential smart contract project.
A standard confidential contract deployment takes 2-4 weeks from kickoff to mainnet. This includes requirements analysis, architecture design, development with FHE libraries (like fhEVM or Zama), internal security review, and deployment. Complex protocols with custom cryptographic circuits or multi-chain deployments can extend to 6-8 weeks. We provide a detailed sprint-by-sprint timeline during the initial scoping call.
