MANTRA Chain resumed operations on August 22 after a roughly 30-hour outage caused by an exploit in its Cosmos-EVM module.

The network halt began late on August 20, when MANTRA detected an attacker exploiting a vulnerability in the upstream software dependency. Developers responded by halting the mainnet entirely, freezing all transactions, staking operations, bridges, and inter-blockchain communication relays.

Block production resumed at around 5:30 a.m. UTC on August 22 after the team deployed version 8.4.0 of its software to fix the flaw and add new security protections.
