Privacy-Preserving Oracle Data API

Deliver sensitive, proprietary data to smart contracts while maintaining confidentiality. We build secure oracle APIs using zero-knowledge proofs and trusted execution environments for institutional-grade DeFi applications.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

Secure, audited smart contracts built to your exact specifications and deployed on-chain.

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.

  • Token Systems: Custom ERC-20, ERC-721, and ERC-1155 contracts 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.

01

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.

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.

01

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.

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.
