Binance pulls SignalPlus API keys after platform flags security issue

On Thursday, Binance revoked the API key connections institutional clients use to access SignalPlus after the Hong Kong-based options platform disclosed a security scare, an issue Deribit also detected. API keys are credentials that let traders automate strategies through third-party tools while balances remain on the exchange; the revocation stops SignalPlus-linked automated trades on Binance but does not affect customer balances. Binance said the incident did not reach its internal systems or customer funds. SignalPlus, founded in 2021 and valued at $500 million after a $50 million HashKey Capital-led Series B1 round in June, provides options and derivatives infrastructure and has raised about $73 million. Binance co-founder CZ urged users to revoke their API keys.
