On August 22, the TAC Protocol experienced an exploit that allowed an attacker to drain a single account before validators halted the chain. The vulnerability was attributed to a flaw in the shared Cosmos EVM precompile layer, not TAC's own code. Following the incident, TAC's token price rebounded by approximately 53% from its all-time low of $0.001129. The attack was contained, affecting only the TAC token supply, with no other assets compromised. The network was halted at block 24,671,475, just minutes after the exploit was detected. This incident marks the third major security issue for TAC in four months, following a $2.8 million theft in May. The current market cap of TAC stands at about $8.3 million, with trading volume at $2.46 million. The recovery of the token is notable but still leaves it down 97.4% from its peak in June.

Key Points: • TAC Protocol halted operations after an exploit drained a single account. • The vulnerability was linked to the Cosmos EVM precompile layer, affecting multiple chains. • TAC's token rebounded 53% from its all-time low following the incident.
