The OKLink multi-chain browser has launched the "Historical Balance Query Tool". Users only need to enter the wallet address and block address to query the historical balance of the main assets of the wallet. The first phase is only open to support Ethereum and USDT asset inquiries . In addition, OKLink OpenAPI also provides this function. At present, according to the data of OKLink’s historical balance query function, the wallet address marked as OKX (starting with 0x5041) has a balance of 1,480,701,105 USDT, and the asset balance of this wallet ranks first among OKX’s public wallet addresses.
