MANTRA Chain Halts Network Over Vulnerability Exploit

MANTRA Chain, a Layer 1 blockchain focused on tokenizing real-world assets, halted its network operations on August 21, 2026, after detecting an attacker exploiting a vulnerability in an upstream software dependency. The precautionary shutdown froze all transactions, endpoints, and bridge operations, temporarily suspending deposits and withdrawals across the ecosystem while the team investigates the security incident.

The network stopped producing blocks at approximately 11:13 p.m. UTC on August 20, with the team issuing its first public notice about the incident about 30 minutes later. According to official statements, the engineering and security teams identified an active attacker exploiting a vulnerability in third-party code used by the chain's infrastructure. The immediate suspension was enacted to prevent further transaction processing and protect the network during the investigation.

"We're aware of an incident affecting MANTRA Chain and have halted the chain as a precaution while we investigate," the team stated. "All endpoints and transactions are currently frozen." The project's status page classified the incident as a full outage affecting public endpoints,...
