After reading all the comments, none of them addressed the root of the problem! I have a suggestion, I hope you'll consider it! This is a very simple database primary key matching issue! The key lies in the settings: Different independent Binance site UIDs should be prefixed with a site/country to form a composite primary key, such as binance-tr-10086, binance-th-10086; during transfers, the receiving site, country, UID, and verification information should be forcibly displayed; cross-site UID direct transfers should be disabled or require strong secondary confirmation. A UID cannot be used alone as a cross-site transfer primary key; it must be accompanied by a platform/country code.
