Submarine Sends for Oracle Data Privacy

overview

CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3 experts.

We architect and deploy custom smart contracts that form the unbreakable logic of your dApp. Our development process is built on audited security patterns and gas-optimized code to protect assets and ensure long-term viability.

Full Lifecycle Support: From initial architecture and Solidity/Rust development to deployment, verification, and ongoing maintenance.
Security-First Approach: All code follows OpenZeppelin standards and undergoes internal review before third-party audits from firms like CertiK or Quantstamp.
Protocol Specialization: Expertise in ERC-20, ERC-721, ERC-1155, custom DeFi primitives, and cross-chain bridges.

We deliver contracts you can stake your business on. Our clients launch with confidence, avoiding the costly exploits that derail projects.

Typical Deliverables: Audited source code, comprehensive technical documentation, deployment scripts, and a post-launch monitoring dashboard.
Outcome: Reduce your time-to-audit by 50% and go to market with contracts engineered for scale and security.

ENTERPRISE-GRADE PRIVACY

Our Submarine Send Implementation

Chainscore delivers a production-ready Submarine Send system that enables your oracle to transmit sensitive data on-chain with zero-knowledge privacy, ensuring data integrity and confidentiality for your users.

Zero-Knowledge Proof Integration

We implement custom zk-SNARKs or zk-STARKs circuits tailored to your data schema, enabling verification of data authenticity without revealing the raw inputs. This protects proprietary data feeds and user privacy.

EXPLORE

On-Chain Commitment & Verification

Our system anchors data commitments to a public blockchain (Ethereum, Polygon, Arbitrum) with verifiable proofs. Clients can trust the data's integrity and timestamp without exposing the underlying information.

Gas-Optimized Smart Contracts

We develop and audit the core verifier and relay contracts using Solidity 0.8+ with OpenZeppelin libraries. Our focus is on minimizing gas costs for proof verification to ensure operational efficiency.

EXPLORE

End-to-End Security Audit

Every implementation undergoes a rigorous security review by our in-house experts, following best practices for cryptographic circuits and smart contract security to mitigate risks before mainnet deployment.

Custom Data Schema Support

We design the system around your specific data types—whether financial prices, IoT sensor readings, or identity attributes—ensuring the privacy logic is perfectly aligned with your oracle's use case.

Relayer Infrastructure & Monitoring

We provide or help you deploy a high-availability relayer service to submit proofs on-chain, complete with 24/7 monitoring, alerting, and failover mechanisms to guarantee service reliability.

DELIVERABLES

Business Outcomes for Your Protocol

Our Submarine Sends service delivers tangible, production-ready infrastructure for private oracle data feeds. Here are the concrete outcomes you can expect.

Private Data Feeds

Integrate sensitive price or data feeds (e.g., from Chainlink, Pyth) into your protocol without exposing them on-chain. We handle the encryption, transmission, and on-chain decryption.

Reduced MEV & Front-Running

Obfuscate critical transaction data (like large swaps or liquidations) until execution, protecting your users from predatory bots and minimizing value extraction.

Obfuscation

Regulatory-Compliant Workflows

Enable selective data disclosure for compliance (e.g., KYC/AML checks) without leaking user information publicly. Data is revealed only to authorized verifiers.

Data Access

Gas Cost Optimization

Our optimized relayer network and batch processing reduce the on-chain footprint of private transactions, lowering overall gas costs for your protocol and its users.

Technical & Commercial FAQs

Submarine Sends: Common Questions

Get clear, specific answers about implementing Submarine Sends for secure, private oracle data delivery. Based on our experience delivering 50+ confidential compute solutions.

A standard Submarine Sends integration takes 2-4 weeks from kickoff to production. This includes architecture review, smart contract development, TEE enclave configuration, and end-to-end testing. Complex multi-chain or custom attestation logic can extend this to 6-8 weeks.
