How scoring works →Summary
MANTRA Chain, a Cosmos-EVM layer-1 blockchain focused on real-world asset tokenization, halted all block production on August 20, 2026 after an attacker exploited a known vulnerability in the shared Cosmos EVM ICS20 precompile module. The network was offline for approximately 30 hours, the native OM token fell 18% to an all-time low of $0.004126, and South Korean exchanges Upbit, Bithumb, and Coinone placed OM on delisting watchlists. This is MANTRA's second major crisis in 2026, following the April 2025 collapse of OM by more than 90%, and occurs in the context of a broader Cosmos EVM security incident that also affected KiiChain and TAC.
