Since the major API leak incident, leading exchanges have strictly controlled trading permission interfaces and implemented IP whitelist binding strategies. Since the implementation of this measure, gray-area operations such as API arbitrage have significantly decreased.

The famous arbitrage incident was very likely caused by internal personnel involvement, as the entire system being compromised is relatively unlikely. This reminds us that the weak link in protection often lies not in the technology itself, but in human factors.

When choosing an exchange partnership plan, a key consideration is that some top platforms offer signal bot features that can operate without granting full trading permissions. This design approach can meet automated trading needs while reducing the risk of API misuse from the source. This permission separation model is worth paying attention to.
