Secure, production-ready smart contracts built by experts for DeFi, NFTs, and enterprise applications.
We architect and deploy audit-ready smart contracts that form the foundation of your Web3 product. Our development process ensures security-first design, gas optimization, and compliance with industry standards like ERC-20, ERC-721, and ERC-1155.
Deliver a secure, functional MVP in as little as 2-4 weeks.
Our ZK-Rollup Privacy-Preserving Oracle is built on a battle-tested, modular architecture designed for high-frequency, high-value data feeds. We deliver verifiable data integrity with zero-knowledge proofs, ensuring your dApp's logic remains private and secure.
We aggregate and process off-chain data within a dedicated ZK-Rollup, generating succinct validity proofs for on-chain verification. This reduces gas costs by >90% versus submitting raw data directly to L1, while maintaining cryptographic security.
Sensitive business logic and data queries are executed confidentially within the rollup's secure environment. The on-chain contract receives only a ZK proof of correct execution, never exposing the underlying input data or proprietary algorithms.
Integrate data from 50+ premium and decentralized sources (Chainlink, Pyth, custom APIs). Our consensus mechanism validates and attests to data accuracy before it enters the rollup, with tamper-proof attestations for audit trails.
Deploy tailored data feeds for derivatives, prediction markets, or private RFQ systems. Our modular design allows for custom aggregation logic, update frequencies, and proof schemes to match your specific use case.
The core proving system and node infrastructure are audited by leading security firms. We provide a 99.9% uptime SLA for data delivery and proof generation, backed by a financially backed service level agreement.
Easily connect to Ethereum, Arbitrum, Optimism, zkSync, and other EVM-compatible chains. Our lightweight on-chain verifier contracts are gas-optimized and support permissioned or permissionless data consumption models.
We architect and deploy production-ready ZK-Rollup oracles that deliver measurable performance, security, and cost advantages for your application.
Integrate off-chain data into your rollup state without exposing sensitive inputs. Our oracles use zero-knowledge proofs to verify data authenticity while preserving user and transaction privacy.
Achieve near-instant transaction confirmation for your users. Our optimized oracle circuits and rollup integration minimize latency, enabling real-time DeFi, gaming, and trading experiences.
Drastically lower operational costs by batching and proving data updates off-chain. Move expensive computation to Layer 2 while maintaining Ethereum-level security guarantees.
Deploy with confidence using formally verified circuits and smart contracts. Every component undergoes rigorous third-party audits (e.g., Trail of Bits) and follows industry security standards.
Go beyond price feeds. We develop bespoke ZK oracles for any verifiable off-chain computation: identity attestations, RNG, cross-chain states, and proprietary business logic.
Get to market faster with our modular oracle stack. Designed for easy integration with StarkNet, zkSync, Scroll, and other major ZK-Rollups, scaling to millions of TPS.
A phased approach to building a custom, privacy-preserving oracle for your ZK-Rollup, from proof-of-concept to enterprise-grade production.

We deliver production-ready ZK-Rollup oracles through a structured, transparent process designed for security, speed, and seamless integration.
We begin with a collaborative workshop to define your data requirements, threat model, and integration points. This ensures the ZK circuit design and on/off-chain architecture are optimized for your specific use case from day one.
Our team builds the ZK circuits (using Circom or Halo2), verifier contracts, and oracle node software. Every component undergoes internal review followed by a formal audit from a leading security firm like Trail of Bits or Spearbit.
We deploy the full system on a testnet (e.g., Sepolia, Holesky) for rigorous integration testing. This phase includes load testing the oracle network, verifying proof generation times, and simulating mainnet conditions to ensure reliability.
We manage the mainnet deployment, including verifier contract deployment and oracle node orchestration. You receive a dedicated dashboard for real-time monitoring of data accuracy, latency, and system health, with 24/7 alerting.

A standard implementation takes 4-8 weeks from kickoff to mainnet deployment. This includes architecture design, circuit development (using Circom or Halo2), smart contract deployment, and integration testing. Complex multi-chain or high-frequency data feeds can extend the timeline. We provide a detailed project plan within the first week.
