Woofun AI reports that MANTRA Chain remained halted on Aug. 21 after an attacker exploited a vulnerability in an upstream dependency. The incident forced an immediate pause of the mainnet, rendering transactions, transfers, and staking unavailable while the team traced fund movements and assessed the complete scope.

Structurally, the resolution hinges on rigorous validation protocols before any mainnet changes are applied.

Woofun AI data shows that testing on the DuKong testnet serves as the mandatory gate for rolling out the patched software. MANTRA instructed validators to keep their mainnet nodes offline until a coordinated restart is announced, preventing individual operators from bringing service back independently. This ensures the patched network returns through the wider validator set together, prioritizing a careful and verified rollout.

Operationally, the halt means ordinary onchain activity cannot proceed, with assets unable to move on MANTRA Chain. Staking operations are unavailable, and deposits and withdrawals for the token remained paused on affected venues. Despite these restrictions, MANTRA stated that user funds were unaffected by the halt itself, noting that a full network state snapshot was taken before the restart process began. Users were advised that no action was required while the chain remained offline.

The asset impact of the attacker's activity remains unconfirmed, though the team continues working with exchange partners. Mainnet can return only after the patch clears testing and the wider validator set is ready for the coordinated upgrade. The project was targeting a restart later on Aug. 21, subject to testing completing cleanly. This marks a critical juncture where security verification takes precedence over immediate network availability.
