MANTRA Chain, an RWA-focused Layer 1 network, completely halted its blockchain after discovering that an attacker had exploited a vulnerability in third-party software. Transactions, validators, public endpoints and some bridge services are currently unavailable.
The MANTRA team did not initially disclose details about the incident. However, according to the latest update published on the project’s status page, the attacker exploited a vulnerability in an external dependency used by the network.
The team identified the vulnerability and began preparing a patched software release. The full impact of the incident and the status of user funds remain unclear.
Why did MANTRA Chain halt transactions?
MANTRA Chain stopped block production as a precaution after detecting the incident. As a result, the network cannot process new transactions and no assets can move on-chain.
The disruption affects MANTRA Chain validators, public blockchain endpoints, Migrate bridge operations and MANTRA-managed IBC relays. Some cryptocurrency exchanges have also temporarily suspended MANTRA deposits and withdrawals.
In its initial statement on X, MANTRA advised users against submitting new transactions. The team said it would not restart the network until it was confident that doing so was safe.
The network will require a coordinated restart
MANTRA engineers are preparing and testing an update designed to close the identified vulnerability. The project’s own validators will remain offline until this process is complete.
Other validators will also need to install the patched release before the network can resume operations. The team will therefore coordinate the restart with the wider validator set.
MANTRA also said it was tracing fund movements connected to the attack and communicating with cryptocurrency exchanges. However, no verified information is available on how many assets the attacker accessed or whether users suffered any losses.
The team said users do not need to take any action at this stage. It also warned against scammers claiming to offer “recovery” or “support” services related to the incident.
MANTRA price falls more than 9%
The network halt increased selling pressure on MANTRA. According to market data, MANTRA coin was trading at around $0.00448 when the article was prepared.
The price fell approximately 9.5% over the past 24 hours. The token dropped as low as $0.004126 during the day, while its 24-hour trading volume surged by more than 500% to over $25 million.
MANTRA replaced the former OM token as part of a transition completed in March 2026. The project distributed 4 MANTRA for every 1 OM and increased the maximum supply to 10 billion tokens.
The network remains offline. The MANTRA team will issue another update after testing the patch and completing coordination with validators.
