Binance removes SignalPlus-linked API keys after reported security issue
In brief
- Binance removed API keys linked to SignalPlus, according to Crypto Briefing.
- Binance called the move a precaution after a reported security issue at SignalPlus.
- Automated SignalPlus strategies on Binance stop working until users set up a new connection.
- Crypto Briefing reported no significant market disruption or price impact from the revocation.
- SignalPlus hasn't published an account of the incident, per the report.
What changed for SignalPlus users
SignalPlus users link their exchange accounts to the platform with API keys. That's how they trade spot, futures and options through SignalPlus tools while their assets stay on the exchange (the funds themselves don't move to SignalPlus).
With those keys pulled, any automated strategy running through SignalPlus on Binance stops until the user reconnects. It's not an unusual power for an exchange to hold: Binance's terms allow it to suspend API keys when security concerns arise, Crypto Briefing noted. SignalPlus's own documentation walks users through creating Binance API keys, and its tutorials recommend IP whitelisting along with trading permissions.
Crypto Briefing reported no significant market disruption or price impact tied to the revocation.
Who SignalPlus is
SignalPlus is a fintech company founded in 2021 and based in Hong Kong. It builds AI-enabled trading tools for digital assets, and its lineup covers options pricing, analytics, automated market-making robots and execution algorithms. Binance is one of several exchanges it integrates with.
According to Crypto Briefing, the company has raised $73M across several funding rounds, most recently a $50M Series B in 2026. The report also said SignalPlus holds ISO/IEC 27001 and SOC 2 certifications and received an A+ rating in penetration testing.
What's still unknown
Details are thin. The security issue has only been reported, and SignalPlus hasn't published an account of the incident, according to the source. Nothing in the report describes what the issue involved.
Will SignalPlus put out its own explanation? Will other exchanges take similar steps? How quickly can Binance users get their connections back up? Crypto Briefing listed all three as open questions, and none of them had been answered when the report ran.
