### Crypto Audit Tools

URL: https://ledgerlens.io/solutions/crypto-audit-tools/

Comprehensive blockchain auditing capabilities including historical balance queries, transaction testing, and cryptographic ownership verification.

#### Historical Balances (#historical-balances)

Query wallet and smart contract balances from our integrated blockchains — whether you need balance data as of a specific historical date and time, a particular block height, or a mass query via .csv upload for thousands of addresses.

Query a single blockchain address by following these steps:

1. **Select Network** — Choose the appropriate blockchain network (e.g., Bitcoin) and asset if applicable.
2. **Enter Address** — Enter the appropriate wallet address for the asset being searched. Ensure that the address is in a valid format for the selected network.
3. **Set Search Parameters** — Specify the query date/time or the block height.
4. **Processing Query** — The system displays the processing status along with the number of rows processed. On success, you'll see the balance, the query date/time, the block height, and a unique query ID. The Query ID is stored for future reference for the audit team.

Key features:

- **Bulk Query (.CSV Upload)** — Mass queries supported by uploading a .CSV file that contains a list of blockchain addresses.
- **Smart Contract Token Supply Query (EVM Chains)** — For Ethereum Virtual Machine (EVM) chains, you can also query the current token supply from smart contracts.
- **Historical Query Log** — All queries made through LedgerLens are recorded for future reference and auditing.

#### Transaction Testing (#transaction-testing)

The Transactions Module in the Auditor's Workbench enables you to query blockchain transactions by transaction ID or by address. In addition, you can review historical query data for your team's past activities.

Bulk Transaction Query process:

1. **Upload .CSV File** — Prepare and upload a CSV file listing multiple Bitcoin transaction IDs.
2. **Processing** — The system processes a set number of transactions (e.g., 25 sample transactions). Results include the transaction hash, block height, block time, and metadata detailing multiple outputs, transferred amounts, and transaction fees.
3. **Download** — Detailed results can be downloaded in CSV or JSON format for further analysis.

Additional options for querying blockchain transactions:

- **Individual Transaction Query** — Retrieve details for a specific transaction by its transaction ID.
- **Address-Based Query** — Look up transactions associated with a particular blockchain address.
- **Historical Query Log** — Access past queries for robust audit documentation.

#### Ownership Verification (#ownership-verification)

Built-in digital signature tools to test with cryptographic certainty.

How it works:

1. **Auditor Issues a Challenge Message** — The auditor generates a unique message (e.g., timestamped string or audit session ID) that must be signed.
2. **Entity Signs the Message** — The entity uses the private key of the wallet to sign the message using the appropriate signing method for the blockchain.
3. **Auditor Verifies the Signature** — The signed message is returned to the auditor, who uses the corresponding public address to verify that the signature is valid and matches the expected wallet.

Key features:

- **Cryptographic Proof of Control** — Entities sign an auditor-issued challenge message with each wallet's private key, proving control without ever revealing the key.
- **No Sensitive Data Exposed** — Verification relies only on public addresses and signatures, so private keys never leave the holder and no confidential information is shared.
- **Independently Verifiable** — Anyone can re-verify a signature against the corresponding public address, so the evidence stands up to independent review.

Why it matters: In blockchain-based audits, it's not enough to simply list wallet addresses. Auditors must confirm that the entity under audit actually controls those wallets — done by having the entity generate a cryptographic signature using the private key associated with each address, a process that can be independently verified without exposing any sensitive information.

Supported chains and signing methods:

| Chain | Signing Method | Tools/Interfaces |
|-------|----------------|------------------|
| Bitcoin | signmessage, PSBT | Bitcoin Core, Electrum, HWI |
| Ethereum | eth_sign, personal_sign | MetaMask, Ledger, Web3 providers |
| Solana | signMessage | Phantom, Solana CLI, Ledger |
| Others | Varies | Chain-specific SDKs or wallets |

#### Supported Chains

**Non-EVM Chains (9):** Aptos, Bitcoin, Cardano, Dogecoin, Hedera Hashgraph, Litecoin, Polkadot, Ripple, Solana.

**EVM Chains (25):** Arbitrum Nova, Arbitrum One, Avalanche, Base, Berachain, Binance Smart Chain, Blast, Celo, Dinari Financial Network, Ethereum, Flare, HyperEVM, Ink, Kava, Linea, Mantle Network, Optimism, Plasma, Plume, Polygon, Sei, Sonic (formerly Fantom), Unichain, XDC, ZKSync.

### Proof of Reserves

URL: https://ledgerlens.io/solutions/proof-of-reserves/

Comprehensive proof of reserves solutions including Merkle Tree verification, on-chain attestations, and real-time monitoring.

#### Merkle Tree Proof of Reserves (#merkle-tree)

Publicly verifiable liability balances while preserving user privacy through cryptographic proof systems.

How a Merkle Tree works:

1. **Extract Customer Liability Report** — Extract a report of all customer balances from the crypto exchange or platform.
2. **Hash Data** — Hash user balance data to maintain privacy.
3. **Create Merkle Tree Structure** — Run the customer liability extract through the LedgerLens Merkle tree generator.
4. **Publish Tree & User Tools** — Use LedgerLens to publish the Merkle Tree.
5. **Verify Customer Accounts** — Enable users to cryptographically verify inclusion within the Proof of Reserves, while still maintaining customer privacy.
6. **Publish Merkle Root in Report** — Publish the Merkle Root within the attestation report, which seals the dataset from future tampering and links the attestation report to the Merkle Tree.

Tools in your Merkle Tree Proof of Reserves toolkit:

- **Merkle Tree Generator** — Easily generate a Merkle Tree in minutes, for up to millions of a client's customers, with our simple step-by-step process.
- **Customer Verification Portal** — Enable your client's customers to verify inclusion within the Proof of Reserves procedures.
- **Merkle Tree Information Delivery via Widget or API** — With a simple line of code, embed the results via widget or API to display Attestation Reports, the Merkle Tree Verification Hub, and summary information about the Proof of Reserves.
- **Customizable and Embeddable Widgets for Delivery** — Change the style, themes, and colors to match your client's website and brand.

#### On-Chain Proof of Reserves (#on-chain)

On-Chain Proof of Reserves brings off-chain reserves data — such as bank balances, gold troy ounces held in vaults, treasury bond CUSIPs & maturity dates, real estate appraisals, and more — onto blockchains through the Chainlink oracle network for use in smart contracts.

On-Chain process flow:

1. **Off-Chain Data Sources** — Tokenized asset reserve data exists off-chain, such as bank balances, T-bills, and more.
2. **API & Data Extraction Methods** — The information is extracted from the source through one of LedgerLens' data delivery methods.
3. **Data Aggregation & Analysis** — The information is ingested and analyzed for completeness and accuracy in accordance with parameters set by the Auditor.
4. **Exposed via API** — A summary of that information is exposed via API to the Chainlink oracle network.
5. **Ingested by the Chainlink Oracle Network** — Node operators read the information and bring it on chain for use in smart contracts, DeFi, and more.

Tools in your On-Chain Proof of Reserves toolkit:

- **Auditor Control Panel** — Configure your settings, manage your engagements, and support your clients with a robust data collection and reporting engine.
- **Live API Endpoint** — Expose a summary of information that is ingested by LedgerLens and exposed to Chainlink node operators. Example response:
  ```json
  {
    "accountName": "STBT",
    "totalReserve": 49245882.16,
    "totalToken": 49072634.3,
    "timestamp": "2024-06-18T10:53:59.491Z",
    "ripcord": false,
    "ripcordDetails": []
  }
  ```
- **Oracle as a Service** — Use Chainlink Functions to streamline and reduce costs for your clients to bring data on chain.

On-Chain Proof of Reserves — Frequently Asked Questions:

- **Is On-Chain Proof of Reserves an "attestation"?** No audit or accounting standards exist for publishing data onto blockchains. Therefore, the output for this service alone is not technically an "attestation" when using the definition adopted by auditors and accountants. However, this product can be paired with Real-Time Proof of Reserves to issue a CPA/CA attestation.
- **How long does it take to integrate and begin reporting with On-Chain Proof of Reserves?** For standard deployments, the process to integrate all data sources, aggregate data, and publish information via API takes a matter of hours, if not minutes.
- **How often is the data published on chain?** The reporting interval is dependent on the least available data source. Assuming all of the token, bank, or other information is readily available via API or similar data extraction method, we can update the endpoint every 30 seconds. The frequency that data is published on chain is dependent on the Oracle Network and parameters set on the Oracle feed. Typically, data is published at minimum once a day, or more frequently as large changes in balance information occur.
- **Who performs these types of engagements?** On-chain Proof of Reserves engagements are performed by independent CPA firms and oracle providers. CPA firms like The Network Firm, the largest crypto-focused CPA firm in the U.S., use LedgerLens to execute on-chain PoR procedures for stablecoin issuers and asset-backed tokens. Oracle providers like Chainlink also leverage LedgerLens to bring off-chain reserve data on chain.

#### Real-Time Proof of Reserves / CPA Examinations (#real-time)

Real-Time Attestations are system-generated CPA/CA attestations. Information is compiled, analyzed, and automatically reported on by the system based on the requirements and inputs set by the auditor.

Real-Time process:

1. **Data Sources** — Begin your real-time journey with LedgerLens' 50+ active integrations.
2. **API & Data Extraction Methods** — Use our API builder or integrate data through a variety of other methods: FTP, FIX, virtual machine, and .csv or .pdf parsing.
3. **Data Aggregation & Analyzing System** — Aggregate the various data sources and apply valuation methodologies as needed.
4. **Attestation Reporting Engine** — Issue a system-generated Auditor's Report protected by LedgerLens' ripcords to ensure no inaccuracies.

Live real-time reserves dashboards (examples): Bitwise Bitcoin ETF (BITB) and CoinShares Physical Bitcoin, delivered via embeddable widgets at widget.real-time-reserves.ledgerlens.io.

Real-Time Proof of Reserves — Frequently Asked Questions:

- **What type of attestation reporting is available?** Real-Time Proof of Reserves currently supports three types of attestation reports: AT-C 205 Examination Reports and AT-C 215 Agreed-Upon Procedures Engagements (both as promulgated by the American Institute of Certified Public Accountants), and ISAE 3000 (Revised) Engagements (as promulgated by the International Standard on Assurance Engagements). The team is looking to expand support for additional attestation and reporting standards, including international engagement and reporting standards.
- **Can I pair Real-Time Reserves with your On-Chain Proof of Reserves service?** Yes. In fact, it is encouraged to provide real-time transparency to your "traditional" users expecting a CPA attestation, along with crypto-native users expecting an On-Chain Proof of Reserves.
- **How long does it take to integrate and begin reporting with Real-Time Reserves?** For most deployments, the standard integration timeline is 2 to 4 weeks once development starts. Development start times are dependent on scoping and client onboarding processes.
- **Who performs Real-Time Reserve attestation engagements?** Certified and Chartered Public Accounting firms use LedgerLens to deliver real-time attestations. CPA firms like The Network Firm (domiciled in the US) and Moore HK (domiciled in Hong Kong) use LedgerLens to deliver attestations for stablecoin issuers, RWA issuers, ETF issuers, and more.

Disclaimer: On-Chain Proof of Reserves alone is not technically an "attestation" under the definition adopted by auditors and accountants; pair it with Real-Time Proof of Reserves to issue a CPA/CA attestation.
