Privacy-Enhanced Rollup Data Availability Solutions

Build a purpose-built data availability layer using ZK-proofs (zk-SNARKs/STARKs) to validate data availability without revealing sensitive transaction details. We implement protocols like Plonky2 or Halo2 for optimal prover efficiency.

Engineer systems for storing encrypted transaction data blobs (EIP-4844 style) with guaranteed availability. We implement secure key management and access controls for authorized data retrieval by sequencers and provers.

Leverage hardware-secured enclaves (Intel SGX, AMD SEV) to process sensitive data off-chain. We design systems where data decryption and state computation occur within a verifiable, isolated environment.

Implement MPC protocols to distribute the trust of a data availability committee. No single party can reconstruct or view the private data, ensuring decentralized confidentiality for your rollup's state.

Develop light client protocols that can cryptographically verify data availability through random sampling (as in Danksharding) without needing to download or inspect the actual private data content.

Build secure, verifiable bridges that enable private state and asset transfers between your rollup and other L2s/L1s. Messages are encrypted end-to-end, with validity proofs ensuring integrity.

Build for MiCA, GDPR, and financial regulations without sacrificing on-chain verifiability. Our architecture separates transaction privacy from data availability, providing audit trails for regulators while shielding user data.

Guarantee data retrievability with our decentralized DA layer. Unlike basic private chains, we provide cryptographic proofs that data is available for fraud proofs, ensuring the same security assumptions as Ethereum.

Deploy a custom confidential rollup in weeks, not years. We provide a modular stack with pre-audited privacy circuits, RPC infrastructure, and block explorers, so your team focuses on application logic.

Drastically reduce transaction costs versus L1 private solutions. Batch thousands of private transactions into a single ZK proof, achieving sub-cent fees while maintaining cryptographic privacy guarantees.

We conduct a deep technical assessment of your application's data flow and privacy requirements. We design a custom data availability layer architecture, selecting the optimal zero-knowledge proof system (e.g., zk-SNARKs, zk-STARKs) and rollup framework (e.g., Polygon CDK, Arbitrum Orbit) for your needs.

Our engineers build the core components: the custom data availability smart contracts, the zk-proof generation pipeline, and the sequencer/validator node software. Development follows strict security standards using Solidity 0.8+ and Rust, with OpenZeppelin libraries and internal peer reviews.

Every line of code undergoes rigorous scrutiny. We engage with top-tier security firms like Trail of Bits or Spearbit for independent smart contract and cryptographic circuit audits. Internal penetration testing simulates mainnet-level attacks on the sequencer and data availability nodes.

We deploy the complete solution to a dedicated testnet (e.g., Sepolia, Holesky). We execute load tests simulating 10,000+ TPS and failure scenarios to validate data availability guarantees, finality times, and economic security under peak load.

We manage the phased mainnet rollout, including contract deployment, validator set initialization, and bridge activation. We provide 24/7 monitoring with SLA-backed 99.9% uptime, real-time alerting for sequencer health, and data availability proofs.

Your solution evolves with the ecosystem. We provide ongoing protocol maintenance, security patch management, and performance optimization. We facilitate seamless upgrades to new proof systems or data availability schemes as technology advances.
