MANTRA Chain Smart Contract Vulnerability: $3.60M Reported Loss

·Historical incident record

Incident Overview

An attacker exploited an unsigned integer underflow vulnerability in the upstream Cosmos EVM module to unauthorizedly transfer approximately 720.9 million MANTRA from two MANTRA-managed addresses (the burn address and a dormant genesis-era multisig). The chain was halted to contain the threat and later resumed after a v8.4.0 patch. No validator keys, admin privileges, or user funds were compromised.
