We architect and deploy production-grade smart contracts that power your token, DeFi protocol, or NFT project. Our process delivers fully audited, gas-optimized code with zero critical vulnerabilities before mainnet launch.
Privacy-Preserving Oracle Data API
Smart Contract Development
Secure, audited smart contracts built to your exact specifications and deployed on-chain.
- Token Systems: Custom
ERC-20,ERC-721, andERC-1155contracts with minting, vesting, and governance modules. - DeFi Protocols: Automated Market Makers (AMMs), lending/borrowing pools, staking, and yield aggregators.
- Enterprise Logic: Multi-signature wallets, asset bridges, and custom business logic for on-chain operations.
- Full Audit Trail: Development includes formal verification, unit/integration testing, and a third-party audit report from firms like CertiK or Quantstamp.
We guarantee your contracts are secure by design, reducing the risk of exploits that can cost millions.
From specification to deployment, we manage the entire lifecycle. You receive comprehensive documentation, a deployment script, and post-launch monitoring—typically within a 3-6 week sprint.
Core Capabilities of Our Confidential Oracle
Our Privacy-Preserving Oracle Data API delivers verifiable, confidential data on-chain, enabling secure DeFi, RWA tokenization, and institutional applications without exposing sensitive inputs.
End-to-End Confidentiality
Data sources, computation, and on-chain delivery are encrypted using Zero-Knowledge Proofs (ZKPs) and Trusted Execution Environments (TEEs). Inputs and business logic remain private, protecting your competitive edge and user data.
High-Frequency, Low-Latency Feeds
Sub-second data updates with deterministic finality. Engineered for high-throughput DeFi protocols requiring real-time price oracles, liquidation triggers, and on-chain derivatives.
Multi-Source Data Aggregation
Aggregate and verify data from 50+ premium and decentralized sources (e.g., CEXs, DEXs, traditional APIs). Our fault-tolerant system ensures data integrity and resilience against source failure or manipulation.
Custom Computation & Logic
Deploy bespoke logic for confidential computations—like TWAP/VWAP, volatility indices, or custom scoring—directly within the secure enclave before on-chain settlement.
Proven Security & Audits
Our core cryptographic circuits and TEE implementations are audited by leading security firms. We follow industry best practices for key management and operational security.
Seamless Chain Integration
Native support for Ethereum, Arbitrum, Optimism, Polygon, and other EVM-compatible L2s. Simple API and SDKs reduce integration time from months to weeks.
Business Outcomes: Why Confidential Data Feeds Matter
Our Privacy-Preserving Oracle Data API delivers more than just encrypted data. It unlocks tangible business advantages by protecting your most sensitive on-chain operations.
Protect Trading Strategies
Deploy high-frequency DeFi strategies without exposing your proprietary logic. Our confidential feeds prevent front-running and MEV extraction, securing your competitive edge.
Secure Institutional Adoption
Meet the stringent data privacy requirements of TradFi institutions and regulated entities. Enable confidential settlement, risk calculations, and compliance reporting on-chain.
Enable Private DeFi Products
Build lending protocols with confidential credit scores, insurance with private claims data, or prediction markets with hidden positions. Expand your product suite securely.
Mitigate Oracle Manipulation Risk
Eliminate the attack vector of public price feed manipulation. Our confidential delivery mechanism ensures data integrity and system resilience against flash loan and oracle attacks.
Future-Proof Your Protocol
Integrate with a forward-looking data layer designed for regulatory evolution. Our architecture supports programmable privacy, allowing you to adapt compliance rules without code changes.
Reduce Operational Liability
Shift the burden of sensitive data handling and compliance from your core protocol to our specialized, audited infrastructure. Focus on product innovation, not data risk management.
Applications for Privacy-Preserving Oracles
Our Privacy-Preserving Oracle Data API enables new categories of on-chain applications by securely delivering off-chain data without exposing sensitive inputs. Here’s how leading teams are leveraging it.
Private DeFi Trading
Build DEXs and lending protocols where order size and intent remain confidential until execution, preventing front-running and MEV extraction. Our oracles provide verifiable price feeds without revealing the underlying trade logic.
Confidential RWA Tokenization
Securely bring real-world asset data on-chain for compliance and settlement. Our API verifies KYC status, credit scores, and asset valuations while keeping user PII encrypted and off-chain.
On-Chain Gaming & NFTs
Create provably fair games with hidden states and random number generation. Enable dynamic, data-driven NFT traits that update based on verified real-world events without exposing the update logic.
Enterprise Data Syndication
Monetize proprietary datasets (financial, IoT, supply chain) for smart contracts. We provide the middleware to cryptographically prove data authenticity and deliver it under strict privacy guarantees.
Cross-Chain Privacy Bridges
Enable secure asset and message transfers between chains where the transaction payload and recipient are concealed. Our oracles act as a verifiable, privacy-preserving communication layer.
Decentralized Identity & Reputation
Build systems where user credentials and social graphs contribute to on-chain reputation scores without exposing the underlying data. Ideal for undercollateralized lending and governance.

Frequently Asked Questions
Get clear answers on how our confidential data feeds integrate with your smart contracts and applications.
Standard oracles (e.g., Chainlink, Pyth) deliver public data on-chain. Our API uses Zero-Knowledge Proofs (ZKPs) and Trusted Execution Environments (TEEs) to fetch, compute, and deliver data without exposing the raw inputs or the querying party. This enables use cases like private price feeds for institutional trading, confidential credit scoring for DeFi, and sensitive supply chain verification that standard oracles cannot support.
