How to Verify OKX's Ownership and Balance of Wallet Addresses

This guide explains how to validate OKX's ownership and balance of wallet addresses using their published reserve snapshot files and open-source reserve verification tools.

Prerequisites for Verification

1. Download Tools

   • Obtain the Reserve Verification Tool and extract the ZIP file.

   • Contains two utilities:

     • Verify Address: Validates address ownership.
     • Check Balance: Verifies address balances (requires rpc.json configuration for node RPC or OKLink API).

2. Download Proof of Reserves File

   • Get the latest Proof of Reserves snapshot.

3. Organize Files

   • Store both the snapshot file and verification tools in the same folder.

Verifying OKX's Ownership of Reserve Addresses

OKX’s snapshot includes addresses, the message "I am an OKX address", signatures, and BTC multisig scripts. Follow these steps to confirm ownership:

1. BTC Wallets (Single/Multi-Signature)

• Multi-Signature Addresses: Use 2/3 signatures. Verify both signatures to confirm OKX controls at least two private keys.
• Single-Signature Addresses: Validate via message and signature.

2. ETH and USDT Wallets

• Ownership is proven through message-signature pairs.

Step-by-Step Verification Using Reserve Tools

1. Terminal Setup

• Mac: Use Terminal.
• Windows: Use CMD.

2. Run Verification Commands

Navigate to the tool’s directory (e.g., cd ~/Downloads/proof-of-reserves) and execute:

For Mac:

./VerifyAddress --por_csv_filename=okx_por_20221122.csv

For Windows:

VerifyAddress.exe --por_csv_filename=okx_por_20221122.csv

Note: Mac users may need to grant permissions via System Preferences > Security & Privacy.

3. Expected Output

A success message:

Verify address signature end, all address passed.

Third-Party Tool Verification

Use these tools for specific address types:

• BTC Single-Signature: Confirm via message/signature.
• EVM Chains (ETH, USDT): Validate with Etherscan.
• TRX Addresses: Use Tronscan.

Example for BTC:

1. Copy an address, message, and signature from the snapshot.
2. Paste into a BTC signature verification site.
3. Match results with OKX’s data.

Validating ETH Staking Assets

Use blockchain explorers (e.g., Etherscan) to:

1. Copy a public key from OKX’s snapshot.
2. Check From/Recipient addresses against ETH staking files.

Verifying Reserve Address Balances

BTC Balance Check

1. Sync Bitcoin Core to the snapshot height (rollback if needed).
2. Configure rpc.json with node RPC details.

3. Run:

   ./CheckBalance --mode="single_address" --coin_name="btc" --address="3A1JRKqfGGxoq2qSHLv85u4zn935VR9ToL" --por_csv_filename=okx_por_20221122.csv

ETH/USDT Balance Check

1. Use default RPC or configure rpc.json with OKLink API.

2. Validate via:

   ./CheckBalance --mode="single_coin_total_balance" --coin_name="eth" --por_csv_filename=okx_por_20221122.csv

FAQ

Q: What if the tool shows an error?

A: Ensure files are correctly placed and RPC/configurations are valid.

Q: Can I use Infura instead of OKLink?

A: Yes! Update rpc.json with Infura/Alchemy endpoints.

Q: How often are snapshots updated?

A: OKX releases periodic snapshots; check their official page.

Appendix: Advanced Configurations

Using Third-Party RPCs (Infura/Alchemy)

Edit rpc.json with EVM chain RPC URLs (e.g., Ethereum Archive Nodes).

OKLink API Setup

1. Generate an API key via OKLink.
2. Configure rpc.json with your API credentials.
