Proof-of-Reserve Valuation Services

We design and implement secure oracle systems that provide continuous, cryptographically verifiable proof of the existence and valuation of off-chain reserves backing tokenized assets.

overview
CORE SERVICE

Smart Contract Development

Secure, gas-optimized smart contracts built for production by Web3-native engineers.

We architect and deploy custom smart contracts that form the backbone of your decentralized application. Our development process is built for security and scale from day one.

  • Security-First Development: Code written in Solidity 0.8+ using OpenZeppelin libraries, followed by rigorous audits (internal + third-party) before mainnet deployment.
  • Gas Optimization: Every line is analyzed for efficiency, targeting up to 40% lower transaction costs for your users.
  • Full-Stack Integration: Contracts are delivered with comprehensive test suites, deployment scripts, and frontend SDKs (ethers.js/web3.js) for seamless integration.

From fungible tokens (ERC-20) and NFTs (ERC-721/ERC-1155) to complex DeFi logic and DAO governance, we build the immutable rules that power your protocol.

ENTERPRISE-GRADE ARCHITECTURE

Core Components of Our Proof-of-Reserve Systems

Our modular, auditable system provides the technical foundation for transparent and verifiable asset backing, built to meet the stringent requirements of exchanges, custodians, and DeFi protocols.

01

Real-Time Reserve Attestation Engine

Automated, cryptographically-verified attestation of on-chain and off-chain reserves. We integrate directly with custody solutions and blockchain nodes to generate immutable proof snapshots at configurable intervals (e.g., hourly).

TRANSPARENT & VERIFIABLE

Our Methodology for Secure, Reliable Systems

Our systematic approach ensures your Proof-of-Reserve valuation is not just a snapshot, but a continuously auditable, tamper-proof system that builds unshakeable trust with users and regulators.

01

Multi-Source Asset Verification

We aggregate and reconcile on-chain data with off-chain custodial attestations from exchanges and financial institutions. This dual-source validation eliminates single points of failure and provides a complete, verifiable picture of reserves.

Proof-of-Reserve Valuation: Key Questions

Essential questions technical leaders ask when evaluating a Proof-of-Reserve (PoR) service provider for their DeFi, CeFi, or stablecoin project.

We employ a multi-source attestation methodology. For fiat reserves, we integrate with qualified third-party custodians (like Fireblocks, Copper) via APIs to pull attested balances. For real-world assets, we work with licensed auditors to verify on-chain attestations of legal claims or tokenized certificates. Our reports clearly distinguish between cryptographically-verifiable on-chain assets and auditor-verified off-chain holdings.
