Question 1

Why Proof of Reserves matters?

Accepted Answer

Our greatest responsibility and number one priority is to ensure your funds are safe and secure at all times. We always maintain 1:1 reserves and pride ourselves on our long standing reputation for best-in-class security. Now, we're empowering you with greater transparency than ever before through Proof of Reserves (PoR).

Question 2

How does Proof of Reserves work?

Accepted Answer

Proof of Reserves is a common audit method used to ensure a custodian holds sufficient funds to cover all assets held on their exchange.

Question 3

How to verify whether your assets are included in the Merkle tree?

Accepted Answer

A snapshot is taken of all eligible users' Trading, Funding, and Grow accounts, and each user is given a unique anonymous user hash ID. Each user's total asset balance becomes a "Merkle leaf" in the tree. Combining the total sum of all our user's assets produces a "Merkle root", a cryptographic signature that represents all user holdings.

Question 4

How to verify the ownership of OKX's wallet address and assets?

Accepted Answer

We published a list of wallet addresses where you can check the OKX assets stored on-chain. These addresses contain a signed message, "I am an OKX address", which confirms our ownership. You can then use third-party or open-source "VerifyAddress" tools provided by OKX to verify our ownership.

Question 5

How to verify the OKX reserve ratio?

Accepted Answer

Compare the total assets held in OKX's on-chain wallets with total user assets from the Merkle root.
