TAC Sidechain Exploit Reveals Faults: The EVM Security Illusion

Why the TAC Sidechain Exploit Exposes the Fault Lines of Synthetic EVM Expansion

EVM compatibility is becoming the most expensive security illusion in decentralized finance.

The recent halt of the TAC sidechain on August 22, 2026, exposes a critical structural vulnerability in cross-chain architecture. While the core TON mainnet remains completely unaffected, the supply-related exploit on this Cosmos-based EVM gateway reveals a deeper architectural crisis.

Ecosystems are increasingly sacrificing native security guarantees to chase Ethereum's dominant developer network effects.

To understand the vulnerability of the current landscape, one must look at the mechanics of cross-chain connectivity. The network suspension of the aforementioned EVM sidechain on its specific late-August launch timeline highlights a recurring structural friction in multi-chain ecosystems. Rather than executing native smart contracts, non-EVM networks increasingly rely on secondary
