Dear Coincall Users,
We would like to inform our users of a potential security concern recently reported by SignalPlus, a third-party trading platform that allows users to connect to cryptocurrency exchanges through API integrations.
As part of our commitment to maintaining a safe and secure trading environment, Coincall is advising all users who have previously connected their accounts to SignalPlus to take precautionary measures to protect their accounts.
What Happened?
SignalPlus has reported a potential security concern involving its services. As a precaution, cryptocurrency exchanges, including Deribit, have taken measures to protect users with API connections to SignalPlus.
At this time, we have no information indicating that Coincall's systems or infrastructure have been compromised or affected by this incident.
Nevertheless, we encourage users with existing or historical SignalPlus API connections to review their account security settings.
Recommended Security Measures
To safeguard your Coincall account, we strongly recommend taking the following actions:
- Review and Revoke SignalPlus API Keys
If you have previously connected your Coincall account to SignalPlus, please review your API management settings and revoke any API keys associated with SignalPlus.
- Review Recent Trading Activity
Check your recent transactions, open orders, and positions for any unusual or unauthorized activity. If you identify suspicious transactions, contact Coincall Customer Support immediately.
- Enable IP Allowlisting
When generating new API keys, enable IP allowlisting wherever available to restrict API access to trusted IP addresses.
- Enable Two-Factor Authentication (2FA)
Ensure that two-factor authentication is enabled on your Coincall account to strengthen account security.
- Exercise Caution Before Reconnecting
We recommend refraining from reconnecting your Coincall account to SignalPlus until SignalPlus provides further clarification and confirmation regarding the security of its services.

The security of our users' accounts and assets remains a top priority at Coincall.
We are closely monitoring developments surrounding this matter and will evaluate additional precautionary measures as necessary.
We will provide further updates should any new information materially affect Coincall users.
