SECURE FOUNDATIONS
Smart Contract Development
Enterprise-grade smart contracts built with security-first practices for DeFi, NFTs, and Web3 applications.
- Security Audits: Every contract undergoes rigorous review using
Slither,MythX, and manual analysis, followingOpenZeppelinbest practices. - Custom Logic: Tailored development for
ERC-20,ERC-721,ERC-1155, staking pools, governance systems, and custom DeFi primitives. - Full Lifecycle: From initial design and testing (
Hardhat,Foundry) to deployment, verification, and ongoing maintenance with upgrade patterns likeTransparent Proxy.
Reduce your time-to-market with a 2-4 week MVP delivery and eliminate costly vulnerabilities before mainnet launch.

Technical & Operational Comparison
ZK Oracle Toolkit vs. Standard Oracle Integration
A detailed breakdown of the key differences between building a custom oracle solution from scratch and leveraging Chainscore's production-ready ZK-Rollup Oracle Proof Toolkit.
| Feature / Factor | Build In-House (Standard Oracle) | Chainscore ZK Oracle Toolkit |
|---|---|---|
Time to Production | 6-12+ months | 4-8 weeks |
Initial Development Cost | $200K - $500K+ | $50K - $150K |
ZK Circuit Expertise Required | High (Hire specialized team) | Zero (We provide pre-verified circuits) |
Security Posture | High Risk (Custom, unaudited code) | Enterprise-Grade (Pre-audited, battle-tested) |
Oracle Data Integrity Proofs | Custom Implementation | Built-in ZK Proofs for all feeds |
Supported Data Feeds & APIs | Your team integrates each one | Pre-built adapters for 50+ major feeds |
Maintenance & Updates Burden | Your engineering team | Handled by Chainscore with optional SLA |
Cross-Chain Data Consistency | Complex to architect | Native feature via our proof aggregation layer |
SLA for Uptime & Latency | You define and maintain it | 99.9% Uptime, <2s finality SLA available |
Total Cost of Ownership (Year 1) | $300K - $750K+ | $75K - $200K (predictable pricing) |

STRUCTURED DELIVERY
Our Delivery Process: From Audit to Integration
A transparent, milestone-driven approach to delivering your ZK-Rollup Oracle Proof Toolkit. We ensure technical excellence, security, and seamless integration at every stage.
01
1. Architecture & Specification
We define the proof system architecture, data models, and integration points. This includes selecting the optimal ZK framework (e.g., Halo2, Plonky2) and designing the on-chain verifier contract.
02
2. Circuit Development & Audit
Our cryptographers implement the core ZK circuits for your oracle's data attestation logic. Every circuit undergoes internal review and is prepared for a formal security audit by firms like Trail of Bits or Spearbit.
03
3. Prover/Verifier Implementation
We build the high-performance off-chain prover service and the lightweight on-chain verifier smart contract. This includes gas optimization for L1 settlement and multi-chain deployment readiness.
04
4. Integration & Deployment
We integrate the toolkit with your existing oracle stack and target rollup (zkSync Era, Starknet, Polygon zkEVM). We manage the deployment, provide comprehensive documentation, and conduct knowledge transfer with your engineering team.

ZK Oracle Proof Toolkit: Key Questions
Get specific answers on implementation timelines, security, and commercial terms for our ZK-Rollup Oracle Proof Toolkit.
Standard toolkit deployment takes 2-4 weeks from kickoff to mainnet-ready integration. This includes custom circuit design for your data feed, proof system integration, and comprehensive testing. Complex multi-feed or cross-chain oracle setups may extend to 6-8 weeks. We provide a detailed project plan with weekly milestones.
