API Keys Revoked: Why Binance Just Blocked SignalPlus Connections
Binance and Deribit both cut SignalPlus off and say their own systems are safe, but every trade, monitor and bot the platform ran on Deribit has stopped.

Binance said it has removed every API key tied to SignalPlus after the options trading platform flagged a possible security problem. The exchange described the step as an immediate precaution, stated that its own systems were not affected and that user funds stay safe. SignalPlus customers were told to log into their Binance accounts to check positions and open orders, and to hold off on linking new keys until SignalPlus confirms the issue is fully resolved. Binance also asked all third-party platforms connected to it to review their security controls. Deribit separately revoked all customer API keys connected to SignalPlus, halting trading, monitoring and automation run through the service there. Binance founder Changpeng Zhao urged anyone using SignalPlus on other exchanges to revoke their keys.
Why it matters: It shows how third-party tools with exchange API access can disrupt trading on several platforms at once, and why exchanges are asking partners to recheck their security controls.
