OKX Discloses $27.8 Billion in Top 4 Assets… Marking 4th Anniversary of Proof of Reserves

OKX published its 49th proof-of-reserves report, disclosing roughly $27.8 billion in reserves across its four largest assets—Bitcoin (BTC), Ethereum (ETH), Tether (USDT), and USD Coin (USDC)—with reserve ratios of 108%, 101%, 106%, and 100%, respectively. The report, released November 2, marks the fourth anniversary of the exchange's proof-of-reserves program, which began in November 2022, and confirms that reserve ratios for all 20-plus covered assets stand at 100% or above. OKX has published the reports monthly, expanding disclosure from three assets initially to more than 20, and its verification framework incorporates Merkle tree-based technology and zk-STARK zero-knowledge proofs. The $27.8 billion figure covers only the four major assets, not the exchange's full disclosed holdings. Watch for whether OKX further expands asset coverage and continues monthly disclosures amid ongoing industry scrutiny of exchange reserve transparency.
