TAC Sidechain Halted After Supply-Related Exploit

TAC, an Ethereum Virtual Machine (EVM) sidechain connected to the TON ecosystem, has halted block production due to a supply-related exploit. The incident occurred on August 22 and affected only the TAC sidechain and its token supply, not the main TON blockchain.

The distinction is crucial because it's often misreported when networks are interconnected. A sidechain can expand an ecosystem's functionality but also creates additional risk surfaces.

A supply exploit can be especially dangerous as it affects trust in the token's accounting. If an attacker can manipulate or duplicate supply, the economic integrity of the network is at risk. Teams may halt block production to prevent further damage while investigating.
