MANTRA Chain halted its network on August 21 after an attacker exploited a vulnerability in an upstream software dependency, freezing validators, public endpoints, bridges and managed relays. The network said this was a precaution while its engineering and security teams, with external partners, investigate the issue. With everything frozen, all deposits and withdrawals to and from MANTRA Chain are currently on hold. MANTRA has said the attacker exploited an upstream dependency, software used by the chain but built outside it, and that it is preparing a patched release. It has not said whether any assets were taken. MANTRA’s team told users to wait for official updates and to rely only on its own channels. In the meantime, the price of the MANTRA token fell as trading activity increased, showing market concerns about the network halt.
What the MANTRA Chain Halt Stopped
The halt has stopped validators from producing blocks, so users cannot move funds, use apps or access bridges. MANTRA says the freeze includes validators, public blockchain endpoints, MANTRA Bridge migration operations, and MANTRA-managed Inter-Blockchain Communication relays. Deposits and withdrawals through affected exchanges are paused as well. MANTRA said users need take no action for now, and that the network will not restart until the team is confident it is safe. A network halt like this preserves the ledger’s state so engineers can check what happened. But MANTRA hasn’t said whether they’ll need to change, roll back, or alter the chain. There’s no information on whether developers are considering a rollback, asset freeze, or any modification to the chain’s state. With a patch in preparation, validators will need to apply and test it before block production resumes.
MANTRA Confirms Exploit, Losses Still Unclear
MANTRA has attributed the incident to an exploited upstream dependency but has not detailed the full scope. No independent security researchers have published evidence of stolen funds. The team has not reported any assets stolen, minted or compromised, so it is still unclear whether anyone lost money. Exchanges have paused deposits and withdrawals, with Upbit among those affected. Trading continues on centralised exchanges, since those orders do not settle on MANTRA Chain. This incident comes as MANTRA works on infrastructure for tokenized real-world assets. Earlier, the project announced a $108.8 million fund for RWA projects, planning to deploy it over four years.
We’re aware of an incident affecting MANTRA Chain and have halted the chain as a precaution while we investigate. All endpoints and transactions are currently frozen.
This means deposits and withdrawals to/from MANTRA Chain are temporarily affected. If you’re unsure how this…

MANTRA Token Falls as Trading Activity Rises
The network pause has affected the MANTRA token. The token fell 18.5% from its 24-hour high to an all-time low of $0.004126 around 11:10 pm UTC Thursday, before recovering to about $0.0044, down roughly 10% on the day, according to CoinGecko. Trading volume rose nearly 600% to about $24 million. The spike points to higher market activity, though not every trade is necessarily linked to the halt. The current token followed a rebrand in early 2026, when the project carried out a 1-to-4 redenomination and replaced the OM ticker without changing holders’ proportional value. Because of the split, current MANTRA prices can’t be compared directly with the old OM price without adjustments.
