MANTRA Chain has halted its mainnet after an attacker exploited a vulnerability in an upstream software dependency, freezing transactions, public endpoints and cross-chain infrastructure while developers prepare a patched release.
The network remains halted with validators and MANTRA-managed infrastructure offline as the patch is tested. Transactions cannot be processed during the shutdown, leaving deposits, withdrawals and asset movements through affected MANTRA Chain services temporarily unavailable.
Fund tracing is underway alongside coordination with exchange partners. No asset-loss figure has been published while the full scope of the exploit is still being assessed.
The shutdown affects MANTRA Chain validators, public blockchain endpoints, MANTRA Bridge Ops and MANTRA-managed IBC relays. Restarting the network requires the patched software to pass testing before validators coordinate a wider mainnet restart.
MANTRA first halted the chain as a precaution shortly after detecting abnormal activity. The vulnerability was later isolated to software used by the chain rather than a user-facing wallet or exchange account.
The incident follows a major infrastructure transition earlier this year. Binance completed MANTRA’s OM token swap and rebranding in March, converting balances at a ratio of 1 OM to 4 MANTRA and opening new MANTRA spot markets.
MANTRA Chain is built around real-world asset tokenization and operates EVM-compatible infrastructure alongside Cosmos-based interoperability.
MANTRA fell from around $0.00506 to $0.004126 as the network disruption hit the market, marking a decline of roughly 18% at the session low.
The token had recovered to about $0.00449 at the latest check but remained down 9.4% over 24 hours. Its 24-hour range stood between $0.004126 and $0.005060, while trading volume jumped to roughly $24.8 million and market capitalization fell near $25 million.
The move adds another major drawdown to MANTRA’s history after the former OM token suffered a 90% collapse in April 2025. The March 2026 redenomination and rebrand reset the token structure, but MANTRA has since fallen about 83% from its post-migration high of $0.02627.
The shutdown comes days after Maya Protocol halted its own cross-chain network following a $1.7 million exploit, with developers similarly moving to patch affected transaction paths before restarting operations.
Another recent breach forced WEMIX to suspend bridges and decentralized trading services after compromised contract ownership enabled 5.23 million WEMIX$ to be minted without authorization.
MANTRA Chain mainnet remains halted, deposits and withdrawals remain paused on affected venues, and validators will stay offline until the patched release is verified and a coordinated restart is ready.
