StarkNet Cairo Oracle Development
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
- Security-First Development: Built with
Solidity 0.8+andOpenZeppelinstandards, following formal verification patterns. - Full Protocol Suite: Custom
ERC-20,ERC-721, staking systems, DAO governance, and DeFi primitives. - Guaranteed Quality: Every contract undergoes internal review and is prepared for third-party audits from firms like CertiK or Quantstamp.
Reduce your go-to-market risk with battle-tested code that handles millions in TVL. We ensure your core business logic is both powerful and provably secure.
Core Technical Capabilities
Our StarkNet Cairo oracle development is built on a foundation of deep protocol expertise and enterprise-grade engineering. We deliver secure, performant, and reliable data feeds that power your DeFi, gaming, and institutional applications on StarkNet.
Cairo 1.0 Smart Contract Development
We architect and deploy high-assurance oracle contracts in Cairo 1.0, leveraging StarkNet's native language for maximum security and performance. Our contracts integrate OpenZeppelin Cairo libraries and follow established security patterns.
Custom Data Feed Integration
Build oracles for any data source: price feeds (FX, crypto, commodities), verifiable randomness (VRF), sports/esports outcomes, or proprietary APIs. We handle the complex logic for aggregation, validation, and on-chain delivery.
Low-Latency & Gas-Optimized Design
Our oracle architectures are engineered for sub-second data finality and minimal L2 gas consumption. We optimize for the unique cost structure of StarkNet's STARK proofs to keep your operational costs predictable and low.
Security-First Development Lifecycle
From design to mainnet, security is paramount. We employ formal verification techniques where applicable, conduct internal audits, and facilitate third-party audits with leading firms like Nethermind and PeckShield before deployment.
Decentralized Oracle Network Design
For production systems requiring high fault tolerance, we design and implement decentralized oracle networks (DONs) on StarkNet. This includes node operator selection, cryptoeconomic incentive models, and slashing condition development.
Integration & Developer Experience
We provide comprehensive integration packages including TypeScript/Python SDKs, detailed documentation, and example dApps. Get from zero to integrated in days, not weeks, with clear testing and monitoring guides.
Business Outcomes for Your Project
Our StarkNet Cairo Oracle development service is engineered to deliver measurable results for your business, from accelerated time-to-market to robust, production-ready data feeds.
Production-Ready Oracle Feeds
We deliver fully audited, gas-optimized Cairo smart contracts that securely fetch and verify off-chain data, enabling your StarkNet dApp to execute complex logic with reliable price feeds, randomness, or custom API data.
Reduced Time-to-Market
Leverage our battle-tested oracle patterns and development frameworks to launch your data-dependent StarkNet application in weeks, not months, bypassing the complexity of low-level Cairo development.
Enhanced Protocol Security
Mitigate oracle manipulation risks with our multi-source data aggregation, decentralized attestation logic, and rigorous security review process, protecting your protocol's assets and user funds.
Cost-Efficient Operations
Our optimized Cairo contracts and efficient L1-L2 messaging strategies minimize StarkNet transaction fees, ensuring your oracle operations remain sustainable at scale without compromising on data freshness.
Scalable Data Infrastructure
Build with a future-proof architecture designed to handle high-frequency updates and increased load. We ensure your oracle scales seamlessly with your user growth and transaction volume on StarkNet.
Expert Technical Partnership

Build vs. Buy: Custom Cairo Oracle vs. Generic Feeds
Choosing the right oracle solution is critical for DeFi, gaming, and prediction market applications. This comparison highlights the trade-offs between developing a custom oracle in-house, using a generic data feed, and partnering with Chainscore for a purpose-built solution.
| Factor | Build In-House | Use Generic Feeds | Chainscore Custom Oracle |
|---|---|---|---|
Time to Market | 4-9 months | 2-4 weeks | 4-8 weeks |
Initial Development Cost | $150K - $400K+ | $5K - $20K (integration) | $50K - $150K |
Data Customization & Logic | Full control | Limited to provider's feeds | Tailored to your dApp's logic |
StarkNet Cairo Expertise Required | Extensive (Senior Devs) | Minimal | Provided by our team |
Security & Audit Burden | High (Your responsibility) | Medium (Relies on provider) | Low (We provide audited code) |
Integration Complexity | Very High | Low | Medium (We handle the complex parts) |
Ongoing Maintenance & Updates | Your team's full-time cost | Provider's roadmap & fees | Optional SLA from $2K/month |
SLA for Uptime & Freshness | You build it | 99.5% typical | 99.9% with penalties |
Long-term Total Cost (Year 1) | $300K - $600K+ | $25K - $50K+ | $75K - $200K |
Strategic Advantage | Proprietary IP | None (same as competitors) | Competitive edge with custom data |
Our Development & Integration Process
We deliver production-ready StarkNet oracles through a structured, transparent process designed for technical founders and CTOs. Each phase includes clear deliverables, security checkpoints, and direct collaboration with your engineering team.
1. Architecture & Specification
We conduct a deep technical discovery to define your oracle's data sources, update triggers, and fee models. The output is a detailed technical specification document, including Cairo contract architecture and integration points with your dApp.
2. Core Cairo Smart Contract Development
Our certified Cairo developers write, test, and optimize the core oracle logic. We implement security patterns from day one, using battle-tested libraries and conducting internal audits for gas efficiency and logic correctness.
3. Off-Chain Relayer & Data Pipeline
We build the robust off-chain component that fetches, validates, and signs data. This includes failover mechanisms, multi-source aggregation, and secure key management, ensuring 99.9%+ data availability and sub-second update capability.
5. Testnet Deployment & Staging
We deploy the complete oracle system to StarkNet testnet (Goerli/SEPOLIA) and integrate it with your staging environment. This phase includes load testing, failure simulation, and final validation of all integration scenarios.
6. Mainnet Launch & Ongoing Support
We manage the mainnet deployment and provide comprehensive documentation for your team. Post-launch, we offer monitoring dashboards, incident response, and upgrade support with a 99.9% uptime SLA for the oracle service.
Custom Blockchain Development
Build, deploy, and scale custom blockchain networks and applications tailored to your business logic.
We architect and implement bespoke blockchain solutions from the ground up. Our team delivers production-ready networks, sidechains, and Layer 2 solutions designed for your specific throughput, privacy, and consensus requirements.
