Mantra token fell 18.5% to a record low, and the blockchain halted block production after a software exploit was discovered. The price dropped from $0.005060 to $0.004126 around 11:10 p.m. UTC, according to CoinGecko, before recovering to about $0.0044, a 10% decline over 24 hours, with trading volume rising to roughly $24 million, a nearly sixfold increase. The network produced its last recorded block at 11:13 p.m. UTC and announced the halt about 30 minutes later in an X post from MANTRA. MANTRA said an attacker exploited a vulnerability in an upstream dependency, though it has not disclosed which software was affected or whether any assets were lost. Validators remain offline while developers prepare a patched release and coordinate with the wider group of operators to restart the network. The incident follows a token collapse of more than 90% in April 2025 and an ongoing acquisition plan by Inveniam Capital Partners, which invested $20 million in 2025 and expects to close the deal in the third quarter. The full scope of the breach and its impact on assets have not been confirmed.
