Why is Proof of Reserves important?
As a cryptocurrency exchange, OKX understands that the safety and security of customer assets are top priorities. We ensure our balance sheet always holds enough assets with a 1:1 reserve ratio, giving us a longstanding reputation for best-in-class security and liquidity.
Our on-chain wallet holdings are also public, allowing you to easily confirm that customer deposits are backed 1:1 by real digital assets.
Our commitment to a 1:1 reserve ratio and monthly Proof of Reserves reports sets a high standard for the crypto industry, demonstrating our dedication to preventing the insolvency of our platform and the accuracy of our customer funds and net balances. This is critical for building trust with regulators and fostering a healthy and sustainable crypto ecosystem.
What is Proof of Reserves?
Proof of Reserves (PoR) ensures that custodians hold sufficient funds to cover all account assets on their platform and deposit liabilities while remaining solvent.
This cryptographic attestation demonstrates that a crypto exchange holds a specific amount of assets on its blockchain at a particular time, providing transparency of aggregate account balances or the total sum of deposits on the exchange. This is achieved without revealing any sensitive information about individual account balances. PoR is a critical component of the crypto ecosystem.
Assets considered reserves are cryptocurrencies offering strong liquidity and market acceptance. OKX offers reserve reports for 22 coins, including
(Zero-Knowledge Scalable Transparent Argument of Knowledge) is a secure method. It relies on Zero Knowledge principles and utilizes the FRI protocol to verify data and prove the authenticity of our reports. In addition, zk-STARK ensures user privacy by not disclosing specific amounts, values, or addresses.
How OKX uses zk-STARK to verify your assets
We take a snapshot of each user's asset balance and input this data into a trace table and an encrypted Merkle tree system. This creates a tamper-proof record, which can be used to verify the accuracy of the balances.
We set three rules or "constraints" that our account asset balances must satisfy. If each constraint is tested and proven true, it confirms the truth of the claims OKX is making.
Rule 1: Total Balance Constraint The total account asset holdings that OKX claims to hold is the sum of every account's total asset balance.
Rule 2: Non-negative Constraint Every account’s total balance is more than zero, and their assets are accounted for, covering their liabilities and ensuring that each account has positive net equity. This is crucial in maintaining the solvency of a crypto exchange.
Rule 3: Inclusion Constraint Every account’s total balance is included in the calculation and verification process.

How to verify the ownership of OKX's wallet address and assets
We published a list of wallet addresses where users can check the OKX assets stored on-chain. These addresses contain a signed message stating, "I am an OKX address," which confirms our ownership.
To verify our ownership, you can utilize either third-party or open-source “
To verify OKX's reserve ratio, compare the total assets held in OKX's on-chain wallets to the total account assets from the Merkle root.
If our total on-chain asset balance equals or exceeds the total account asset balance, the reserve ratio will confirm that OKX has Proof of Reserves.
Note: The report is a snapshot of our OKX account asset balances at the time of the data capture. Any tokens outside of the scope or subsequent transactions made after the snapshot are not included.
