overview
CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
From a 2-week MVP to a complex multi-chain system, we deliver contracts that are secure, gas-optimized, and upgradeable.
- Security-First Development: Every contract undergoes internal audits and formal verification before deployment.
- Full-Stack Integration: We provide deployment scripts, testing suites, and frontend SDKs for seamless integration.
- Protocol Expertise: Specialized in
ERC-20,ERC-721,ERC-1155, staking mechanisms, and custom DeFi primitives.

DELIVERABLES
Business Outcomes for Your Application
Our privacy-preserving oracle network design delivers verifiable, secure data feeds that enable new product capabilities while protecting user and business data.
01
Regulatory-Compliant Data Feeds
Deploy oracles that deliver critical market data (prices, volatility) while maintaining data source confidentiality. Enables DeFi products in regulated markets without exposing proprietary sourcing logic.
Zero-Knowledge

Architectural Comparison
Standard Oracle vs. Privacy-Preserving Design
Key differences between traditional oracle designs and Chainscore's privacy-preserving network architecture for sensitive data.
| Architectural Component | Standard Oracle Design | Chainscore Privacy-Preserving Design |
|---|---|---|
Data Privacy | ||
On-Chain Data Exposure | All data is public on-chain | Only encrypted commitments or zero-knowledge proofs |
Data Source Confidentiality | Sources are often identifiable | Sources are anonymized via decentralized attestation |
Computation Model | Simple data fetch & relay | Trusted Execution Environments (TEEs) or MPC for private computation |
Audit Trail | Fully transparent, public ledger | Selective, verifiable disclosure for compliance |
Integration Complexity | Low to Medium | Medium to High (requires cryptographic integration) |
Ideal Use Case | Public price feeds, weather data | Private credit scoring, institutional trading, healthcare data |
Regulatory Alignment | Limited for sensitive data | Designed for GDPR, HIPAA, and financial compliance |
Implementation Timeline (Typical) | 2-4 weeks | 6-12 weeks |
Ongoing Operational Overhead | Low | Managed by Chainscore with optional SLA |
use-cases
CRITICAL USE CASES
Applications Requiring Query Privacy
Our privacy-preserving oracle design is engineered for applications where the data request itself is sensitive. We ensure your application logic and user behavior remain confidential, preventing front-running and protecting competitive advantage.
01
Private DeFi Trading & Liquidity
Secure large-scale DEX trades and liquidity strategies by hiding order intent from public mempools. Prevent MEV extraction and front-running for institutional and high-frequency trading protocols.
Zero
Intent Leakage
Sub-second
Query Latency
02
Confidential RWA Tokenization
Oracles for real-world asset valuations (real estate, private equity) where price discovery and verification logic must remain private to protect sensitive commercial agreements and investor data.
