How to Verify Ownership and Balance of OKX Wallet Addresses

In the world of cryptocurrency, transparency and trust are paramount. To ensure users can independently verify asset reserves, OKX provides a public proof-of-reserves (PoR) snapshot and open-source tools for community validation. This guide walks you through how to verify both wallet address ownership and on-chain balances using OKX’s official resources—empowering you with full control over trust verification.

Whether you're a security-conscious investor or a blockchain auditor, this step-by-step walkthrough covers everything from downloading verification tools to interpreting results across major chains like Bitcoin (BTC), Ethereum (ETH), USDT, and more.

What You Need Before Verification

Before starting the verification process, prepare the following:

Download the proof-of-reserves snapshot file
Visit the OKX Proof of Reserves page and download the latest .zip archive containing the PoR CSV file.
Extract and locate two key tools inside the folder:
- VerifyAddress: Validates ownership of OKX wallet addresses.
- CheckBalance: Confirms that on-chain balances match those in the published snapshot.
Ensure both the PoR file and verification tools are placed in the same directory for smooth operation.

👉 Verify your crypto holdings with confidence using trusted open-source tools.

How to Verify OKX Wallet Address Ownership

OKX publishes cryptographic proof that it controls its wallet addresses through signed messages and multi-signature scripts. These proofs are embedded in the PoR snapshot and can be independently verified.

Understanding Cryptographic Proof Methods

For Bitcoin (BTC) Wallets

Single-Signature Addresses:
OKX signs a message like "I am an OKX address" with the private key linked to the address. If the signature validates against the public address, ownership is proven.
Multi-Signature Addresses (2-of-3):
Two out of three private keys sign the message. Since only OKX holds all three keys, two valid signatures confirm they control the address.

For Ethereum (ETH), USDT, and EVM-Compatible Chains

A signed message such as "I am an OKX address" is paired with the wallet address and digital signature. Anyone can use public tools to validate this triplet and confirm ownership.

Step-by-Step: Verify Address Ownership Using OKX’s Open-Source Tool

Open your system terminal:
- Mac: Launch Terminal
- Windows: Open Command Prompt
Navigate to your download folder:
```
cd ~/Downloads/proof-of-reserves
```
Run the VerifyAddress tool:
- Mac:
```
./VerifyAddress --por_csv_filename=okx_por_20250401.csv
```
- Windows:
```
VerifyAddress.exe --por_csv_filename=okx_por_20250401.csv
```
🔒 If you get a "developer cannot be verified" warning on Mac, go to System Preferences > Security & Privacy > General, unlock the settings, and allow apps from App Store and identified developers.

Wait for results:
A successful verification returns:

Verify address signature completed, all addresses passed

This confirms that every wallet address in the snapshot is cryptographically owned by OKX.

Alternative: Verify Ownership Using Third-Party Tools

You can also use third-party verifiers for additional assurance.

Example: Verifying a BTC Single-Signature Address

Open the PoR CSV file.
Copy one entry including:
- Wallet address
- Signed message (e.g., "I am an OKX address")
- Signature data
Go to a BTC message verifier (like BitAuth or other open-source tools).
Paste all three fields.
If validated successfully, ownership is confirmed.

✅ This method applies similarly to EVM-based chains (Ethereum, Arbitrum, Optimism, etc.) and TRON (TRX).

How to Verify Ownership of Staked ETH Assets

For staked ETH, OKX validators are listed on the Ethereum beacon chain. You can verify control via:

Open the staking-specific PoR file.
Copy a validator’s public key.
Visit beaconcha.in or similar explorer.
Paste the public key.
Check if:
- "Sender Address" and "Recipient Address" match those in OKX’s published staking records.
These addresses are signed by OKX, proving ownership.

How to Verify OKX Wallet Balances

Balance verification ensures that the total assets claimed in the PoR snapshot actually exist on-chain at a specific block height.

The Two Key Checks

Per-Address Balance Match:
Compare individual wallet balances at snapshot block height with values in the CSV.
Total Coin Balance Match:
Sum all on-chain balances for a given cryptocurrency (e.g., BTC) and compare with OKX’s published total.

These checks prevent asset inflation or misrepresentation.

How to Verify BTC Address and Total Balance

Option 1: Use Bitcoin Core Node (Most Accurate)

Download Bitcoin Core v0.21+.

Create ~/.bitcoin/bitcoin.conf with:

server=1
rpcuser=OKX
rpcpassword=OKXWallet

Start the node:
```
./bitcoind
```
Wait ~12 hours for full sync.

Roll back to snapshot block height:

Find the next block’s hash after the snapshot.

Run:

./bitcoin-cli invalidateblock 00000000000000000005829017993a7a21e4b7c731c95b9cb979c01294a7bd27

Query balances using RPC commands.

Option 2: Use CheckBalance Tool (Simpler)

Edit rpc.json to configure BTC RPC parameters.

Run in terminal:

Single Address Check (Mac):

./CheckBalance --mode="single_address" --coin_name="btc" --address="3A1JRKqfGGxoq2qSHLv85u4zn935VR9ToL" --por_csv_filename=okx_por_20250401.csv

Total BTC Balance Check (Windows):

CheckBalance.exe --mode="single_coin_total_balance" --coin_name="btc" --por_csv_filename=okx_por_20250401.csv

Compare output with PoR file values.

How to Verify ETH/USDT Balances Across Multiple Chains

OKX supports ETH and USDT across various networks including:

Ethereum Mainnet
Optimism
Arbitrum
Polygon
Avalanche C-Chain

Use CheckBalance with proper coin identifiers.

Example: Verify Single ETH Address Balance

./CheckBalance --mode="single_address" --coin_name="eth" --address="0xc5451b523d5fffe1351337a221688a62806ad91a" --por_csv_filename=okx_por_20250401.csv

Example: Verify Total USDT on Arbitrum

./CheckBalance --mode="single_coin_total_balance" --coin_name="usdt-arbitrum" --por_csv_filename=okx_por_20250401.csv

💡 Supported coin names include: btc, eth, usdt-erc20, usdt-trc20, eth-optimism, usdt-poly, usdt-avaxc, etc.

You can use:

Default RPC settings (no config needed)
Third-party nodes (e.g., Infura, Alchemy)
OKLink API for faster queries

FAQ Section

Q: Why does OKX publish proof of reserves?

A: Proof of reserves allows users to independently verify that OKX holds sufficient assets to back user funds, enhancing transparency and platform trustworthiness.

Q: Can anyone fake these proofs?

A: No. Cryptographic signatures require possession of private keys. Without access to OKX’s keys, forging valid signatures is computationally impossible.

Q: What does "2-of-3 multi-sig" mean for BTC wallets?

A: It means two out of three private keys must sign a transaction. OKX uses this model for security—proving ownership without exposing all keys.

Q: Do I need technical skills to verify?

A: Basic command-line knowledge helps, but step-by-step guides make it accessible even for non-developers.

Q: Is my data safe when using these tools?

A: Yes. The tools run locally on your machine—no personal information is uploaded or shared.

Q: How often are snapshots updated?

A: OKX regularly updates its proof-of-reserves files; always use the most recent version for accurate verification.

Final Thoughts

Verifying wallet ownership and balance isn’t just for experts—it's a powerful way for every user to participate in platform accountability. With OKX’s open-source tools and transparent snapshots, you hold the keys to trust.

Whether checking a single ETH address or auditing billions in BTC reserves, these methods put verification power directly in your hands.
