CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
- Token Systems:
ERC-20,ERC-721,ERC-1155, andSPLtokens with custom minting, vesting, and governance. - DeFi Protocols: Automated Market Makers (AMMs), lending/borrowing pools, staking mechanisms, and yield optimizers.
- Enterprise Logic: Multi-signature wallets, access control systems, and verifiable on-chain data oracles.
- Gas Optimization: Code reviewed for >30% gas reduction on high-frequency functions.
We deliver fully tested, documented, and audit-ready contracts in 2-4 weeks for an MVP, enabling rapid market validation.

Build vs. Buy: Custom Private Feed vs. Public Oracles
A technical and economic comparison of implementing a private, verifiable data feed for your ZK-Rollup versus relying on public oracle networks.
| Critical Factor | Build In-House Team | Use Public Oracle (e.g., Chainlink) | Chainscore Private Feed |
|---|---|---|---|
Time to Production | 6-12 months | 2-4 weeks | 4-8 weeks |
Upfront Development Cost | $250K - $600K+ | $5K - $50K (integration) | $75K - $200K |
Data Privacy & Custom Logic | Full control | None (public data only) | Full control with zero-knowledge proofs |
ZK-Circuit Integration Complexity | Extreme (your team) | Low (standard adapter) | Managed (we handle it) |
Security Audit Burden | High (unaudited risk) | Medium (oracle network risk) | Low (pre-audited framework) |
SLA & Uptime Guarantee | Your responsibility | Network-dependent (no direct SLA) | 99.9% with financial backing |
Ongoing Maintenance (Year 1) | $150K+ (2 engineers) | Variable gas + service fees | $30K - $80K (optional SLA) |
Prover Efficiency & Cost | Unoptimized (high cost) | N/A | Optimized circuits (up to 40% cheaper) |
Time to First Proof of Concept | 3-4 months | 1-2 weeks | 2-3 weeks |

PROVEN FRAMEWORK
Our Delivery Methodology
A structured, four-phase approach designed for predictable delivery, transparent collaboration, and enterprise-grade security for your ZK-Rollup private data feed.
01
Phase 1: Architecture & Design
We define your data privacy requirements and design a custom ZK-Rollup architecture. This includes selecting the optimal proving system (e.g., Plonk, Groth16), designing the data availability layer, and finalizing the smart contract interface.

Frequently Asked Questions
Get clear answers on timelines, security, and process for implementing a private data feed with ZK-Rollups.
A standard implementation takes 4-8 weeks from kickoff to mainnet deployment. This includes 1-2 weeks for architecture design and circuit specification, 2-4 weeks for core development and testing, and 1-2 weeks for security audits and final integration. Complex requirements like custom proof systems or multi-chain support can extend the timeline, which we scope and quote for upfront.
