MANTRA Chain Mainnet Halted Due to Exploit Mitigation

The MANTRA Chain Mainnet (mantra-1) was halted at block 17,449,398 following the identification of an exploit. A full state snapshot was taken before the halt, ensuring no third-party user, exchange, or partner funds were impacted. The root cause analysis has been completed, and the attack vectors associated with the exploit have been mitigated in the upcoming v8.4.0 patched release. This version is currently in pre-release, having been validated against an internal chain environment with successful dry-run testing. The network remains halted to coordinate a single, coordinated upgrade among validators. The upgrade will patch the vulnerability in the EVM module exploited and includes additional security hardening. Validator instructions are being coordinated, with binaries to be taken only from the official release tag. The restart window will be posted once validator coverage is confirmed.

Key Points: • MANTRA Chain Mainnet halted at block 17,449,398 to address a security exploit. • No third-party funds were impacted; root cause and attack vectors have been identified and mitigated. • The v8.4.0 patch is in pre-release, with dry-run testing successfully completed.
