StarkNet Cairo Verifiable Data Feed Development

Real-time price feeds for crypto, FX, and commodities with sub-second updates. Built with Cairo for StarkNet's ZK-rollup efficiency, ensuring your DEX or lending protocol has the freshest data.

Every data point is cryptographically verified on StarkNet L2. Our Cairo contracts implement robust validation logic, providing tamper-proof guarantees for settlement and liquidation events.

Need a feed for a novel asset, proprietary index, or specific TWAP calculation? We develop bespoke Cairo smart contracts to source, compute, and publish your unique data on-chain.

Aggregated from multiple CEXs, DEXs, and institutional providers with sophisticated outlier detection. Our infrastructure ensures data integrity and resilience against market manipulation.

Our feeds are engineered for minimal L2 gas consumption. We use StarkNet's native capabilities and Cairo best practices to keep your protocol's operational costs predictable and low.

From initial design and audit to mainnet deployment and 24/7 monitoring. We provide ongoing maintenance, upgrades, and incident response, so your team can focus on core product development.

Deploy verifiable data feeds (price oracles, randomness, sports scores) with Cairo 1.0 smart contracts, fully integrated with your StarkNet application logic.

Leverage StarkNet's validity proofs to cryptographically guarantee the correctness of off-chain computations and data aggregation before on-chain settlement.

Engineered for sub-second data finality on StarkNet L2, reducing update costs by 50-100x compared to Ethereum L1 oracles while maintaining security.

All feeds undergo formal verification with Cairo's native tooling and security audits following OpenZeppelin standards, with a focus on economic and liveness guarantees.

Tailor data sourcing, aggregation (TWAP, median, volume-weighted), and dispute mechanisms to your protocol's specific risk model and economic design.

Receive complete source code, deployment scripts, monitoring dashboards, and operator documentation—no vendor lock-in. You control the entire stack.

We start by mapping your specific data needs (price feeds, randomness, custom logic) to an optimal Cairo architecture. We design for minimal on-chain footprint and maximum data integrity.

Our certified Cairo developers write, test, and optimize the core verifiable logic. We implement best practices for gas efficiency, security patterns, and StarkNet's unique compute model.

We build the robust off-chain infrastructure that fetches, processes, and submits data with cryptographic proofs. This includes high-availability relayers and integration with SHARP or custom provers.

We deploy to StarkNet testnets (Goerli, Sepolia) for comprehensive integration testing under realistic conditions, including stress tests and failure scenario simulations.

We manage the production deployment and establish 24/7 monitoring, alerting, and incident response protocols. You receive full documentation and operational handoff.
