MANTRA Chain stays offline after exploit as Aug. 21 restart hinges on patch test

MANTRA Chain remained halted on Aug. 21 after the team said an attacker exploited a vulnerability in an upstream dependency. Transactions, transfers, and staking are unavailable while the mainnet is paused.MANTRA identified the vulnerable software only as an upstream dependency. In its official incident record, the team said it was tracing fund movements, working with exchange partners, and continuing to assess the complete scope.The incident record shows MANTRA first froze endpoints and transactions while reviewing the root cause and impact. It later attributed the precautionary halt to an attacker exploiting the upstream dependency, then announced the patched release and testnet testing, with the mainnet remaining offline throughout those updates.The project's latest update said user funds were unaffected by the halt itself and that a full network state snapshot was taken before the restart process began. That assurance is limited to the network pause, which prevents transactions from being processed. The asset impact of the attacker's activity remains unconfirmed.Patch testing controls the restartMANTRA said patched release v8.4.0 addresses the underlying vulnerability and is un...
