This precautionary measure was taken to ensure the security and integrity of the network while validators conduct a comprehensive review. No confirmed security incident or loss of user assets has been reported, and ONT, ONG, and other on-chain assets are currently unaffected. Users are advised to avoid time-sensitive transactions until the network is confirmed safe to operate. The duration of the pause is currently undetermined, with the focus on thorough assessment over speed. Ontology's core development team is collaborating with validators and ecosystem partners during this investigation. Further updates will be provided through official channels as more information becomes available.
