Mainnet halted — patched release staged for coordinated restart — Dry-Run Testing Successful, Security Hardening and Final Review in Progress MANTRA Chain Mainnet ( mantra-1 ) remains halted at block 17,449,398. A full state snapshot was taken before the halt. No third-party user, exchange, or partner funds were directly impacted. Where things stand:

Root cause identified. We have completed a root cause analysis of the exploit and reviewed the known attack vectors associated with it. Each has been mitigated in the patched release.

Remediation built and tested. v8.4.0 is in pre-release state and has been validated against an internal chain environment that replicates Mainnet state, with repeated end-to-end upgrade rehearsals.

Stability before speed. The network stays halted while we coordinate the broader active validator set for a single, coordinated upgrade. We would rather spend the coordination time than resume on a partial set.

v8.4.0. It patches the vulnerability in the EVM module used in the exploit and carries supplemental security hardening. Store upgrades are empty — no module changes and no state migrations, so the upgrade itself completes in seconds. Sequence. MANTRA-operated validators upgrade first. Mainnet validator partners follow, and standard node operators, RPC, and archive nodes immediately after. Validator instructions are being coordinated directly with operators; binaries should be taken only from the official release tag and verified against the published checksums. We will post the restart window and the go signal here once validator coverage is confirmed. Thanks again for all your support.
