EVM network halts block production after supply exploit as TON connection remains dark

TAC, an EVM network connected to TON, halted validator block production after the project said an exploited vulnerability affected the Cosmos-based EVM side of its network and, according to TAC, only the TAC token supply.

In an Aug. 22 notice, the team said it was working with validators on a temporary halt that would take effect within minutes. TAC's official Telegram announcement channel subsequently described the halt as implemented and promised further findings and steps toward resuming the chain.
