Crypto exchange OKX disclosed $7.5 billion in reserves of Bitcoin (BTC<\/a>), Ether (ETH<\/a>) and Tether (USDT<\/a>) as part of its monthly proof-of-reserves (PoR) report. Based on data from blockchain analytics firm CryptoQuant, OKX claims to have the \u201clargest clean asset reserves among major exchanges.\u201d<\/p>\n OKX claims to maintain 1:1 reserves, which would mean means the company\u2019s on-chain assets 100% match the customer\u2018s balances. The report shows current reserve ratios of 105% for BTC, 105% for ETH and 101% for USDT.<\/p>\n The term \u201cclean\u201d is used in proofs of reserves to describe crypto assets that do not include an exchange’s platform tokens and are purely made up of high-market-capitalization crypto assets, such as BTC, ETH and USDT.<\/p>\n CryptoQuant monitors PoRs across the industry. A clean reserve is defined by the firm as:<\/p>\n \u201cA clean reserve is the total reserve of each exchange, excluding exchange native token. There can be a risk in the exchange\u2019s liquidity if a self-issued token holds a significant percentage of the total reserve amount. Hence, we have applied the clean reserve to visualize the liquidity of each exchange transparently.\u201d<\/p><\/blockquote>\n Related:\u00a0Proof of reserves is becoming more effective, but not all its challenges are technical<\/a><\/em><\/strong><\/p>\n The analytics firm concluded OKX\u2019s assets to be 100% clean. The PoR report, which is available on OKX\u2019s website,\u00a0includes<\/a> historical reserve ratios data and liabilities. According to the company, it has published more than 23,000 addresses as part of its Merkle tree PoR program \u201cand will continue to use these addresses to allow the public to view asset flows.\u201d<\/p>\n
