OKX has reached a four-year milestone for its Proof of Reserves program, reporting $36.36 billion in on-chain assets across 22 major cryptocurrencies. The exchange maintains reserve ratios of 110% for Bitcoin, 100% for Ethereum, 105% for Tether, and 101% for USD Coin.

The company utilizes cryptographic verification, including zk-STARKs technology, to allow users to verify their holdings independently. This system combines publicly accessible on-chain wallet data with monthly reporting to ensure transparency regarding asset backing.

Alongside its reserve program, OKX launched the Shield security initiative in the US and Europe in October 2026. This program offers eligible customers protection against unauthorized account takeovers with potential reimbursements reaching up to $500 000.

Adoption rates for the Shield program have been significant in Europe, where nearly 45% of VIP customers and over 21% of daily active users activated the protection within weeks of its release. Currently, more than 37% of customer assets in the region are covered by the service.
