Privacy-Preserving Proof-of-Reserve Oracle

overview

CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built for scale and compliance.

We architect and deploy audited, gas-optimized smart contracts on EVM chains (Ethereum, Polygon, Arbitrum) and Solana. Our development process ensures security and reliability from day one.

Security-First Development: Built with Solidity 0.8+ and OpenZeppelin libraries, followed by third-party audits from firms like CertiK or Quantstamp.
Gas Optimization: We reduce transaction costs by up to 40% through efficient storage patterns and contract architecture.
Full-Stack Integration: Seamless connection to frontends, oracles, and indexers via custom APIs and event listeners.

Deliver a market-ready product in 4-6 weeks, not months. We handle the entire lifecycle from spec to mainnet deployment.

Our contracts power:

DeFi Protocols: DEXs, lending/borrowing platforms, yield aggregators.
Token Ecosystems: Custom ERC-20, ERC-721, and ERC-1155 with advanced minting and staking logic.
Enterprise Solutions: Supply chain tracking, credential verification, and asset tokenization with compliance modules.

ENTERPRISE-GRADE VERIFICATION

Core Capabilities of Our ZK Proof-of-Reserve Oracle

Our oracle delivers cryptographic proof of solvency without exposing sensitive financial data. Built for exchanges, custodians, and DeFi protocols that require trustless, real-time reserve verification.

Zero-Knowledge Proof Generation

We generate succinct, verifiable ZK-SNARKs that prove asset holdings match liabilities, using industry-standard circuits (Plonk, Groth16). Clients prove solvency without revealing wallet addresses or transaction amounts.

Multi-Chain & Multi-Asset Support

Aggregate and verify reserves across Ethereum, Solana, Bitcoin, and other major L1/L2 networks. Supports native tokens, wrapped assets (wBTC, wETH), and institutional custody solutions (Fireblocks, Copper).

Real-Time On-Chain Verification

Automated, frequent proof generation with on-chain verification contracts. Anyone can independently verify a proof's validity in a single transaction, providing continuous, trust-minimized assurance to users and regulators.

Privacy-Preserving Audit Trail

Maintain a complete, immutable, and privacy-compliant audit trail of all proofs. Data is hashed and stored on-chain, enabling regulatory compliance (e.g., for MiCA) without exposing raw financial data.

Custom Proof Schemas & Integration

Tailor proof logic for specific business rules, liability definitions, or regulatory requirements. We provide SDKs and APIs for seamless integration into existing dashboards, reporting tools, and front-ends.

Security & Cryptographic Audits

Our entire stack—from circuit design to verification contracts—is audited by leading security firms. We implement formal verification for critical circuits and maintain a bug bounty program.

TANGIBLE RESULTS

Business Outcomes for Your Platform

Integrating a privacy-preserving Proof-of-Reserve oracle delivers concrete advantages beyond technical compliance. Here’s how it directly impacts your business metrics and user trust.

Enhanced Market Trust & Liquidity

Provide verifiable, real-time asset backing without exposing sensitive wallet details. This demonstrable transparency attracts institutional capital and reduces counterparty risk for users, directly increasing platform liquidity and trading volume.

Real-time

Proof Updates

Zero Exposure

Wallet Privacy

Regulatory Confidence & Compliance

Meet and exceed evolving global standards for financial transparency (e.g., MiCA, FATF Travel Rule) with an auditable, cryptographic proof system. Simplify regulatory reporting and due diligence for enterprise partners and auditors.

Architectural Comparison

Transparent vs. Privacy-Preserving Proof-of-Reserve

A technical breakdown of traditional transparent PoR versus modern privacy-preserving alternatives, highlighting key operational and security differences.

Feature	Transparent Proof-of-Reserve	Privacy-Preserving Proof-of-Reserve
Data Exposure	Full asset/liability ledger is public	Only cryptographic proof of solvency is public
Competitive Risk	High (reveals treasury strategy)	None (confidential business data protected)
Verification Method	Manual wallet checks by users	Automated, cryptographically-verified zero-knowledge proofs
Audit Frequency	Scheduled (weekly/monthly)	Real-time or on-demand (hourly)
User Trust Model	Trust, but verify (manual)	Trustless, verifiable computation
Implementation Complexity	Low (simple API/display)	High (requires ZK-SNARK/STARK circuits)
Regulatory Compliance	Challenging for privacy laws (e.g., GDPR)	Simplified (no PII/raw data shared)
Time to Integrate	2-4 weeks	6-10 weeks
Typical Cost	$10K - $30K (development + audits)	$75K - $200K+ (circuit dev + audits)
Ideal For	Early-stage protocols, transparent DeFi	Institutions, regulated entities, competitive markets

TRANSPARENT & PREDICTABLE

Our Delivery Process: From Audit to Integration

A structured, four-phase engagement model designed for technical leaders. We deliver a production-ready, privacy-preserving Proof-of-Reserve oracle with clear milestones and guaranteed outcomes.

Phase 1: Architecture & Audit Review

We conduct a deep technical assessment of your existing reserve structure and smart contracts. This phase establishes the zero-knowledge proof (ZKP) circuit design and data attestation strategy, ensuring the oracle's logic is sound before a single line of code is written.

Deliverable: Comprehensive architecture document and security design review.

1-2 weeks

Typical Duration

Design Sign-off

Phase 2: Core Circuit & Contract Development

Our team builds the custom ZK-SNARK/STARK circuits for reserve verification and the on-chain verifier contracts. Development follows OpenZeppelin standards and includes gas optimization for mainnet efficiency.

Deliverable: Auditable circuit code (Circom/Halo2) and deployed, testnet-verified smart contracts.

Frequently Asked Questions

Get clear answers on how our oracle service works, its security, and what to expect when you partner with us.

Our oracle uses zero-knowledge proofs (ZKPs) to cryptographically verify asset holdings. Custodians generate a ZK proof that their on-chain reserves match their off-chain holdings, which our oracle validates and publishes on-chain. This process confirms solvency without revealing the exact wallet addresses, transaction history, or total balance amounts to the public, maintaining full privacy.
