Proof of Reserves Audit Methodology

Our Proof of Reserves approach provides assurance through a multi-phase process. Each phase is designed to transparently verify your reserves, culminating in a clear and credible showcase of trust.

Phase 1

Strategic Scoping & Onboarding

The process begins with a kickoff to establish a clear foundation for the audit. This initial phase is critical for aligning on objectives and ensuring a smooth, predictable process.

Define PoR Audit Scope: We partner with your team to define a clear audit scope, timeline, and a precise list of all in-scope assets and networks.
Plan Skynet Integration: We establish the plan for integrating the final verification results with your public Skynet profile to provide maximum community visibility.

Phase 2

Privacy-Preserving Liability Verification

Next, our engineers focus on the first side of the ledger: your user liabilities. This phase is dedicated to cryptographically proving the total value of user funds with a process that prioritizes accuracy and user privacy.

Client Liability Report: Under our supervision, your team generates a Client Liability Report, which is a snapshot calculating all user balances for the in-scope assets.
Data Privacy & Hashing: To protect user privacy, we collect only the minimum necessary data. For confidentiality, each user is assigned a unique user hash, ensuring auditors cannot link specific balances to identifiable individuals.
Merkle Tree Integrity: This privacy-protected data is used to construct a Merkle Tree, allowing us to aggregate all user liabilities into a single Merkle Root Hash, which serves as a cryptographic proof of the total liability amount.

Phase 3

Complete Asset & Ownership Verification

Simultaneously, we verify the assets held in reserve. This track focuses on providing undeniable proof that your organization has complete control over all wallets holding the assets.

Wallet Address Collection: Our team obtains a complete list of all public keys and addresses from your management that hold the in-scope assets.
Ownership Proofs: We conclusively prove your control over these addresses using secure and verifiable on-chain methods, including:
- "Send-to-Self" Transactions: Verifying control by monitoring a small, pre-defined transaction sent from each address.
- Custom Digital Signatures: Establishing ownership by having you sign a custom message with each private key.

Phase 4

Integrated Analysis & Reporting

In the final phase, we bring the two verification tracks together to provide a clear picture of your reserve status, translating technical verification into a powerful, public showcase of your commitment to transparency.

Collateralization Analysis: We conduct a meticulous one-to-one comparison of your total verified assets against your total verified liabilities.
Valuation & Reporting: To ensure accuracy, we standardize asset values using a common currency (e.g., USD) and pull prices from multiple leading data sources. We then calculate the collateral ratio for each asset, ensuring it exceeds 100%.
Skynet Showcase & Attestation: The results are delivered in a detailed attestation report and activated on your public Skynet profile, turning your PoR audit into a live showcase of trust for the entire Web3 ecosystem.

A one-time Proof of Reserves audit is typically completed in 2 weeks, depending on the scope and complexity. The engagement concludes with two key deliverables: a detailed attestation report for your records and the public activation of your verification status on your Skynet profile.
