Binance has removed API keys linked to SignalPlus, a Hong Kong-based trading tools platform, after a reported security issue. The move cuts the connection between Binance accounts and SignalPlus, and automated strategies running through it would stop working until users reconnect.
Binance removed the API keys linked to SignalPlus as a precaution following a reported security issue at the platform. The action targets the connection between Binance accounts and SignalPlus, and it does not appear to target anyone's funds directly.
Users connect their exchange accounts to SignalPlus with these keys, which let them trade spot, futures and options through SignalPlus tools while their assets stay on the exchange. Therefore, any automated strategy running through SignalPlus on Binance would stop until users set up a fresh connection.
Binance's terms allow the exchange to suspend API keys when security concerns come up. The exchange also tells users to delete compromised keys right away, and it effectively did that on their behalf here. So far, no significant market disruption or price impact is tied to the revocation.
SignalPlus is a fintech company founded in 2021 that builds AI-enabled trading tools for digital assets. It has raised $73M across several funding rounds, the most recent a $50M Series B in 2026.
The company has also highlighted its security credentials. SignalPlus holds ISO/IEC 27001 and SOC 2 certifications and received an A+ rating in penetration testing. Its tutorials recommend IP whitelisting along with trading permissions, so a key only works when requests come from approved internet addresses.
Users who reconnect will likely want to check what permissions their new keys carry and whether whitelisting is turned on. Still unclear is whether SignalPlus will publish an account of the incident.
