OKX has released its 47th consecutive proof-of-reserves report, showing 139,865 BTC in customer account assets as of a Sept. 8, 2026 snapshot. That figure is up 4.07% from the Aug. 11 snapshot, a net increase of 5,466 BTC.
The exchange reported $27.4 billion in primary assets across 22 supported coins. Wallet assets for Bitcoin totaled 153,151 BTC, producing a BTC reserve ratio of 109%, down from 111% in August. OKX classified 146,359 BTC as exchange-held and 6,792 BTC as held through third-party custody.
Ether user holdings rose 3.49% to 1.786 million ETH, while wallet assets reached 1.796 million ETH and the ETH reserve ratio stayed at 101%. USDT customer balances increased 4.62% to 8.49 billion tokens, with a USDT reserve ratio of 105%, slightly below the prior 106%.
Other reported coverage remained at or above 100%: USDC at 100%, XRP at 108%, DOGE at 101%, Solana at 105%, and OKB at 100% after rounding. The exchange said its proof-of-reserves methodology uses zk-STARK proofs, Merkle-tree data, and published wallet addresses so users can independently verify their balances were included without exposing personal account information.
OKX emphasized that the snapshot is a point-in-time comparison of assets under its control against customer balances, not a full financial audit, and that reserve ratios do not represent gains or returns for customers.
