TAC EVM network halts block production due to supply exploit

TAC, an EVM network linked to TON, has halted validator block production following a vulnerability exploit affecting its Cosmos-based EVM side and specifically the TAC token supply. On August 22, the team announced a temporary halt in collaboration with validators, which was implemented shortly thereafter. As of August 23, the latest block recorded was 24,671,475, timestamped August 22, with no new blocks produced by August 24. TAC's announcements did not disclose details regarding unauthorized TAC amounts, financial losses, or the specific nature of the exploit. The halt raises questions about the reconciliation of TAC balances across various categories, including native and wrapped tokens, which remain unanswered. This incident differs from a previous breach on May 11, where TAC reported a total protocol loss of approximately 2854486.22 dollars. The current halt is a broader operational response but does not indicate a new loss figure or confirm a connection to the earlier incident. Technical details and a timeline for resuming operations have yet to be provided.
