Blockchain analytics company Chainalysis has restored Reactor, KYT and Address Screening after a security incident exposed account information for all its users. Its Investigations API and Rapid Lookup services remained under maintenance on Nov. 9.
The company announced the return of Reactor and its screening products at 18:50 UTC on Nov. 7, saying it was emailing customers instructions for reconnecting with enhanced security measures.
The snapshot below records the earlier Nov. 7 position before that restoration announcement, not the current status.
The service dashboard listed KYT's interface and API, along with Address Screening, as operational on Nov. 7. Reactor, Investigations API and Rapid Lookup were under maintenance. Those operational labels therefore do not mean every screening customer has regained access.
KYT monitors transactions, Address Screening assesses wallet risk exposure, and Reactor helps investigators trace funds across blockchains. Reactor has since returned, while the Investigations API and Rapid Lookup outages continue.
