Cairo StarkNet ZK-Data Storage Solutions

We build high-assurance smart contracts in Cairo for StarkNet, specializing in ZK-verified data storage logic, access control, and gas-efficient state management.

• Security First: Development follows OpenZeppelin patterns and includes formal verification where applicable.
• Protocol Integration: Seamless integration with StarkNet's native storage and account abstraction.

Design and deploy storage systems where data integrity and state transitions are provable via zero-knowledge proofs. We implement Merkle trees, verifiable logs, and state commitments on-chain.

• Verifiable Off-Chain Data: Store data off-chain with on-chain ZK proofs of correctness.
• Data Availability: Architect solutions aligned with Ethereum's data availability requirements.

Full-stack development environment setup, including local testnets, CI/CD pipelines for Cairo contracts, and monitoring dashboards for your StarkNet applications.

• DevEx Focus: Automated testing with Protostar, deployment scripting with StarkNet CLI.
• Production Monitoring: Real-time tracking of transaction success rates and contract events.

Our contracts undergo rigorous internal review and can be prepared for external audits by leading firms. We employ static analysis, fuzzing, and manual review to ensure robustness.

• Audit-Ready Code: Deliver comprehensive documentation and test suites for smooth third-party audits.
• Proven Track Record: Experience with audits for DeFi and NFT protocols on L2s.

Build secure bridges and oracle integrations to bring verifiable external data onto StarkNet or prove StarkNet state to other chains, enabling composable DeFi and NFTs.

• Trust-Minimized Bridges: Implement light client or optimistic verification patterns.
• Oracle Design: Create ZK-verified data feeds for price, identity, or real-world events.

Optimize your Cairo contracts and storage patterns for minimal prover costs and maximum throughput. We profile and refactor to reduce STARK proof generation time and fees.

• Gas & Fee Analysis: Identify and eliminate bottlenecks in storage writes and computation.
• Horizontal Scaling: Design architectures for sharding data across multiple contracts.

Every Cairo smart contract undergoes formal verification using tools like Giza and Protostar. We provide third-party audit reports from firms like Nethermind and ABDK to ensure mathematical correctness and security.

We design custom STARK circuits for your data storage logic, focusing on proving time reduction and cost efficiency. Our methodology includes circuit size optimization and recursive proof aggregation.

We architect scalable data models using StarkNet's storage proofs and state diffs. Our designs ensure efficient data availability, historical querying, and seamless integration with L1 Ethereum for finality.

Secure, transparent upgrade patterns using proxy contracts and time-locked multisigs. We implement governance modules for parameter tuning without introducing centralization risks.

Post-deployment, we provide real-time dashboards for proof generation health, storage costs, and sequencer status. We offer 99.9% uptime SLAs with dedicated on-call support.
