How to Verify OKX's Wallet Address Ownership and Balances

In the evolving world of cryptocurrency, transparency and trust are paramount. Exchanges like OKX have taken significant steps toward proving their financial integrity by publishing proof-of-reserves (PoR) data. This article walks you through the complete process of verifying OKX’s wallet address ownership and on-chain balances using publicly available tools and snapshot files.

By following this guide, you can independently confirm that OKX holds the private keys to its published addresses and possesses sufficient on-chain assets to back user funds—ensuring accountability in a decentralized ecosystem.

Understanding Proof-of-Reserves Snapshots

OKX regularly releases cryptographic snapshots of its reserve holdings. These files include:

• Public wallet addresses
• Asset balances at a specific block height
• Signed messages proving ownership
• Multi-signature redemption scripts (for BTC)

These snapshots allow users to verify two critical claims:

1. Ownership: OKX controls the private keys of the listed addresses.
2. Solvency: The total on-chain balance matches or exceeds user liabilities.

Preparing for Verification

Before diving into verification, ensure your environment is set up correctly.

Step 1: Download the Verification Tools

Obtain the official open-source Proof-of-Reserves verification toolkit, which includes:

• VerifyAddress: Validates ownership via digital signatures.
• CheckBalance: Confirms on-chain balances match published data.

After downloading, extract the ZIP file to a dedicated folder.

Step 2: Get the Reserve Proof File

Download the latest okx_por_*.csv snapshot file from OKX’s official portal. Place it in the same directory as the verification tools.

Step 3: Configure Connection Settings

The tool uses rpc.json to connect to blockchain nodes. You can choose:

• Local node (full control)
• Third-party services (e.g., Infura, Alchemy)
• OKLink Open API (recommended for ease)

You’ll edit this file later based on your preferred method.

Supported Cryptocurrencies and Networks

OKX supports reserve verification across multiple chains and tokens:

• BTC – Bitcoin network
• ETH – Ethereum, Arbitrum, Optimism
• USDT – ERC-20 (Ethereum), TRC-20 (Tron), Polygon, Avalanche, Arbitrum, Optimism

This cross-chain support ensures comprehensive validation regardless of where assets are held.

Verifying Wallet Address Ownership

Proving ownership confirms that OKX holds the private keys to each address. This is done using signed messages and cryptographic proofs.

For Bitcoin (BTC) Addresses

BTC wallets use two types of signatures:

Multi-Signature (2-of-3)

Each multi-sig address requires two valid signatures out of three possible private keys. The snapshot includes:

• Redeem script
• Two signatures

Using VerifyAddress, you can validate both signatures, confirming OKX controls at least two keys—proving ownership without exposing all secrets.

Single-Signature

A message like "I am an OKX address" is signed with the private key. The tool verifies that the signature corresponds to the public address.

For Ethereum and USDT (EVM & TRON Chains)

EVM-compatible chains (Ethereum, Arbitrum, etc.) and TRON use personal message signing:

• Message: "I am an OKX address"
• Signature and address are cross-checked cryptographically

If the signature validates against the address, ownership is confirmed.

Using the VerifyAddress Tool

Follow these steps to run ownership checks:

1. Open Terminal

   • macOS: Launch Terminal
   • Windows: Use Command Prompt

2. Navigate to Tool Directory

   cd ~/Downloads/proof-of-reserves

3. Run Verification Command

   macOS:

   ./VerifyAddress --por_csv_filename=okx_por_20221116.csv

   Windows:

   VerifyAddress.exe --por_csv_filename=okx_por_20221116.csv

4. Review Output
   A successful result returns:

   Verify address signature end, all address passed

This confirms every listed address is provably owned by OKX.

Alternative: Third-Party Ownership Verification

You can also use external tools for manual checks:

BTC Single-Signature Address

1. Copy address, message, and signature from the CSV.
2. Visit a BTC signature verifier site.
3. Paste all three fields.
4. If validated, ownership is confirmed.

EVM-Based Addresses (ETH, USDT on Ethereum, etc.)

Use an Ethereum message signer tool:

• Input message: "I am an OKX address"
• Provide signature and address
• Tool confirms cryptographic match

TRON (TRX) Chain

Use TRON’s official wallet or third-party tools supporting TRX address validation with signed messages.

Verifying On-Chain Balances

Ownership alone isn’t enough—you must also confirm that balances match what’s claimed.

Two Key Checks:

1. Individual address balance at snapshot block height
2. Total sum of all addresses for a given asset

This prevents manipulation through inflated or outdated data.

Step-by-Step Balance Verification

For Bitcoin (BTC)

Step 1: Set Up Bitcoin Core Node

1. Download Bitcoin Core (v0.21+).

2. Create ~/.bitcoin/bitcoin.conf with:

   server=1
   rpcuser=OKX
   rpcpassword=OKXWallet

3. Start node: ./bitcoind
4. Wait ~12 hours for full sync.

5. Roll back to snapshot block:

   ./bitcoin-cli invalidateblock <block-hash>

6. Confirm rollback with:

   ./bitcoin-cli getblockcount

Step 2: Configure rpc.json

Set BTC RPC settings:

"btc": {
  "rpc_url": "http://127.0.0.1:8332",
  "rpc_user": "OKX",
  "rpc_password": "OKXWallet"
}

Step 3: Run CheckBalance Tool

Check Single Address:

./CheckBalance --mode="single_address" --coin_name="btc" --address="3BdEq8vnX1o1J4Zpwj6wkPh5FxrgxLAibr" --por_csv_filename=okx_por_20221116.csv

Check Total Balance:

./CheckBalance --mode="single_coin_total_balance" --coin_name="btc" --por_csv_filename=okx_por_20221116.csv

Compare output with CSV values—matching results prove solvency.

For ETH / USDT on EVM Chains

No need to run a full node—use public APIs.

Options:

1. Default RPC – Pre-configured (limited rate)
2. Infura / Alchemy – Reliable third-party archive nodes
3. OKLink API – High-performance blockchain data service

Configure rpc.json for OKLink:

"eth": {
  "api_key": "your_oklink_api_key",
  "api_url": "https://www.oklink.com/api/v5/explorer/address/balance"
}

Run Commands:

Single Address Check:

./CheckBalance --mode="single_address" --coin_name="eth" --address="0x0003d703d621f2e458bee467f6e8683743933174" --por_csv_filename=okx_por_20221116.csv

Total Balance Check:

./CheckBalance --mode="single_coin_total_balance" --coin_name="eth" --por_csv_filename=okx_por_20221116.csv

Supported coin names:
BTC, ETH, ETH-ARBITRUM, ETH-OPTIMISM, USDT-ERC20, USDT-TRC20, USDT-POLY, USDT-AVAXC, USDT-ARBITRUM, USDT-OPTIMISM

A match between tool output and published data confirms full reserve backing.

Frequently Asked Questions (FAQ)

Q: Why should I verify exchange reserves?
