Binance Cuts SignalPlus API Access After Potential Security Issue
Binance has removed every API key linked to third-party trading platform SignalPlus as a precaution after the platform reported a potential security issue. The action, announced on November 5, 2026, disconnects existing SignalPlus integrations with Binance accounts while the reported issue is being addressed.
Binance said its own systems were unaffected and customer funds remained safe. The exchange instructed affected users to access their Binance accounts directly to review active positions and open orders rather than relying on their connected SignalPlus interface.
Why Binance Revoked SignalPlus API Keys
The decision followed a security warning from SignalPlus, a platform that provides cryptocurrency options trading tools, analytics, and automated trading infrastructure. Its services allow users to connect exchange accounts and manage trading activity through API integrations.
An API key is a credential that allows an external application to interact with an exchange account. Depending on the permissions granted, it can provide access to account information and trading functions, including placing or cancelling orders. Binance explains these permissions in its official API documentation.
By removing all SignalPlus-linked keys, Binance cut off the existing API connections as an immediate protective measure. The exchange has not publicly detailed the precise nature of SignalPlus's reported security issue, the number of affected users, or whether any unauthorized activity occurred through the integration.
What Binance Is Asking Affected Users to Do
Binance advised anyone who used SignalPlus to sign in to their Binance account directly and check their positions and open orders. This allows users to review their trading activity through the exchange itself while the third-party connection remains disabled.
The exchange also recommended that users wait until SignalPlus confirms that the security issue has been fully resolved before reconnecting API keys. Re-enabling an integration prematurely could restore access before the underlying concern has been addressed.
Binance further emphasized the importance of IP whitelisting. This security feature restricts API access to approved IP addresses, adding another layer of protection if API credentials are exposed or misused.
Binance Calls for Stronger Third-Party Security Controls
The exchange also urged other third-party platforms integrated with Binance to review their security systems and monitor for unusual activity. Companies that identify potential risks were encouraged to contact Binance immediately.
The incident highlights the security considerations involved when traders connect external applications to centralized exchanges. These integrations can provide useful trading and analytics functions, but they also create additional access points that need to be secured.
Binance's API security guidance advises users to protect their credentials, avoid unnecessary permissions, and revoke keys if suspicious activity is detected. Its API Key Terms also outline the responsibilities and risks associated with sharing API access with third-party services.
SignalPlus Integration Remains Suspended Pending Resolution
The immediate impact for affected Binance users is the loss of automated access through their existing SignalPlus API connections. Users can still review their positions and orders directly through Binance, but they should not assume that their previous integrations will continue working.
SignalPlus describes itself as a platform offering options pricing, analytics, liquidity aggregation, and automated trading tools. Its official website outlines these services and its trading infrastructure.
For now, the key next step is confirmation from SignalPlus that the reported security issue has been resolved. Binance has made clear that users should wait for that confirmation before generating or reconnecting API access.
The exchange's action is a precautionary response, not confirmation that Binance itself was breached or that SignalPlus users suffered losses. Further details about the incident will depend on updates from the platform and any additional security findings.
