Binance Revokes API Keys Linked to SignalPlus Following Reported Security Issue
Binance has revoked API keys connecting user accounts to SignalPlus, taking precautionary action after a reported security issue involving the Hong Kong-based digital asset trading platform. The move disables the connection between the two services but does not appear to involve direct restrictions on users' funds.
SignalPlus users rely on exchange API keys to access trading features through its platform. These connections allow them to execute spot, futures, and options trades while keeping their assets on the exchange. By removing the keys, Binance has interrupted that access until affected users establish new connections.
Binance API Revocation Disrupts Automated Trading Connections
The revocation means automated strategies operating through SignalPlus on Binance will stop functioning until users generate and configure replacement API keys. The immediate impact is therefore operational rather than a direct loss of access to funds held on Binance.
Binance's terms allow the exchange to suspend API keys when security concerns arise. The exchange also advises users to delete keys they believe may have been compromised. In this case, Binance effectively carried out that precautionary step on behalf of affected users.
No significant market disruption or price impact has been reported in connection with the API key revocation.
SignalPlus Background and Security Credentials
Founded in 2021 and headquartered in Hong Kong, SignalPlus develops AI-enabled trading tools for digital assets. Its products include options pricing and analytics, automated market-making robots, and execution algorithms.
The company has raised $73 million across several funding rounds. Its latest financing was a $50 million Series B round in 2026. SignalPlus integrates with multiple cryptocurrency exchanges, including Binance, and provides documentation explaining how users can create API keys to connect their accounts.
Those setup instructions recommend IP whitelisting alongside trading permissions. The feature restricts API requests to approved internet addresses, adding a layer of control over where a key can be used.
SignalPlus has also highlighted its security credentials, including ISO/IEC 27001 and SOC 2 certifications, as well as an A+ penetration-testing rating.
Users Face Reconnection and API Permission Checks
For affected traders, restoring automated activity will require creating new API keys and reconnecting their Binance accounts to SignalPlus. Users will also need to review the permissions assigned to replacement keys and consider enabling IP whitelisting.
The incident puts attention on the security assurances SignalPlus has promoted, particularly following its $50 million Series B funding round this year. However, the available information does not establish the precise nature or scope of the reported security issue.
Key developments to watch include whether SignalPlus publishes an explanation of the incident, whether other exchanges take comparable precautionary measures, and how quickly Binance users are able to restore their connections.
