ZK-Rollup Data Feed Setup | Chainscore Labs

overview

CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built for scale and compliance.

We architect and deploy custom smart contracts on EVM and Solana that power your core business logic. Our development process is built on OpenZeppelin standards and includes formal verification for critical financial functions.

From MVP to Mainnet: Go from concept to a fully audited, gas-optimized contract in as little as 2-4 weeks.
Security-First: Every line undergoes static analysis, unit testing, and peer review before our recommended third-party audit.
Protocol Integration: Native support for ERC-20, ERC-721, ERC-1155, SPL, and custom token standards.

We don't just write code; we engineer systems that hold and move value securely.

Our engineers specialize in complex DeFi primitives, NFT mechanics, and cross-chain bridges. We provide complete documentation, deployment scripts, and a post-launch monitoring dashboard to ensure your contracts perform as intended under real-world load.

ARCHITECTURE & DELIVERY

Core Technical Capabilities

We deliver production-ready ZK-Rollup data feeds with enterprise-grade privacy, security, and performance. Our proven stack ensures your sensitive financial data remains confidential while enabling verifiable on-chain computation.

Custom ZK-Circuit Design

We architect and implement zero-knowledge circuits tailored to your specific data feed logic (e.g., price oracles, risk scores). Built with Circom or Halo2 for optimal proving efficiency and verifier gas costs.

EXPLORE

Privacy-Preserving Data Ingestion

Secure, multi-source data aggregation with TLS 1.3 encryption and MPC protocols. We implement attestation mechanisms to ensure data integrity from origin to the proving layer before private computation.

EXPLORE

High-Performance Prover Infrastructure

Deployment of scalable, auto-scaling prover clusters on AWS/GCP to generate ZK proofs in under 5 seconds. Includes monitoring, load balancing, and 99.9% uptime SLA for continuous feed operation.

On-Chain Verifier & Settlement

Gas-optimized Solidity verifier contracts deployed on your target L1 (Ethereum) or L2. We ensure minimal settlement latency and cost for finalizing private computation results on-chain.

EXPLORE

End-to-End Security Audit

Comprehensive audit of the entire stack—circuits, data pipeline, prover logic, and smart contracts—conducted by our in-house security team following OpenZeppelin standards. Final report delivered pre-deployment.

Managed Operations & Monitoring

Full lifecycle management including 24/7 system health monitoring, alerting via PagerDuty/Slack, proof failure recovery, and quarterly performance reviews. We handle the infrastructure so you focus on your product.

DELIVERABLES

Business Outcomes for Your Prediction Platform

Our ZK-Rollup data feed setup delivers measurable infrastructure improvements, directly translating to competitive advantages and revenue growth for your prediction market.

Zero-Knowledge Data Integrity

We implement ZK-SNARK proofs to cryptographically verify off-chain data feeds on-chain, ensuring tamper-proof odds and market resolution without revealing the underlying data source. This builds unshakeable user trust in your platform's fairness.

100%

Verifiable Integrity

Data Leakage

Sub-Cent Transaction Costs

By batching thousands of predictions and settlements into a single L1 transaction, we reduce user gas fees to fractions of a cent. This enables micro-prediction markets and removes cost as a barrier to user engagement.

Frequently Asked Questions

Get clear answers on our process, security, and outcomes for implementing private, scalable data feeds with ZK-Rollups.

Standard deployments for a production-ready, privacy-preserving data feed take 2-4 weeks from kickoff to mainnet launch. This includes circuit design, smart contract development, integration, and security audit. Complex multi-chain or custom oracle integrations may extend to 6-8 weeks. We provide a detailed project plan with weekly milestones during the scoping phase.
