OKX's Commitment to Asset Transparency
As a leading digital asset exchange, OKX prioritizes user fund security through:
- Maintaining 1:1 asset reserves at all times
- Publishing monthly PoR reports
- Providing industry-leading security and liquidity
- Offering transparent on-chain wallet verification
Our publicly available wallet addresses allow users to independently verify their funds are fully backed by real assets.
Understanding Proof of Reserves
Proof of Reserves ensures cryptocurrency exchanges:
- Hold sufficient on-chain assets to cover all customer balances
- Maintain adequate liquidity for withdrawals
- Operate with full transparency without compromising user privacy
OKX provides PoR for 22 digital assets including BTC, ETH, and major stablecoins.
How Proof of Reserves Works
- zk-STARK Verification: Uses zero-knowledge proofs to validate all OKX account assets
- Wallet Ownership Verification: Confirms control of OKX's on-chain addresses
- Reserve Ratio Validation: Compares on-chain assets to customer balances
What is zk-STARK?
Zero-Knowledge Scalable Transparent Argument of Knowledge (zk-STARK) is an advanced cryptographic method that:
- Validates data authenticity without revealing sensitive information
- Uses FRI protocol for audit verification
- Preserves user privacy while proving reserve adequacy
How to Verify OKX's Proof of Reserves
Step 1: Verify Inclusion Constraint
- Access your account data via the Reserve Proof Dashboard
- Copy your verification JSON file (must end with "_inclusion_proof.json")
- Download OKX's open-source zk-STARK Validator
- Run the validator to check inclusion status
Successful verification will display:
"Inclusion constraint validation passed"
Step 2: Verify Balance Sum and Non-Negative Constraints
- Download the zk-STARK file from your account
- Extract "sum_proof_data.json"
- Place validator tool in same directory
- Execute validation check
Positive results show:
"Total sum and non-negative constraint validation passed"
Step 3: Verify Wallet Ownership
For BTC verification:
- Compare your wallet address with OKX's published list
- Validate ownership using the message "I am an OKX address"
- Use third-party tools or OKX's Signature Verifier
- Check balances at the snapshot block height
