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 (@MANTRA_Chain on X).

The network remains offline with validators and MANTRA-managed infrastructure down as the patch is tested, according to the project's status page (status.mantrachain.io). Transactions cannot be processed during the shutdown, leaving deposits, withdrawals and asset movements through affected MANTRA Chain services temporarily unavailable. Because a mainnet halt stops the chain itself rather than a single application, the outage reaches every service that depends on MANTRA infrastructure until validators return. Fund tracing is underway alongside coordination with exchange partners, and no asset-loss figure has been published while the full scope of the exploit is still being assessed.

Validators Await Patched MANTRA Release

The shutdown affects MANTRA Chain validators, public blockchain endpoints, MANTRA Bridge Ops and MANTRA-managed IBC relays, the Cosmos ecosystem's channels for moving assets between separate chains. Restarting the network requires the patched software to pass testing before validators coordinate a wider mainnet restart, a sequence common to Cosmos-based networks, which resume only when validators adopt a fixed release in coordination.

MANTRA first halted the chain as a precaution shortly after detecting abnormal activity. The vulnerability was later isolated to software used by the chain — an upstream dependency, meaning code the network relies on beneath its application layer — 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, so mainnet availability underpins the chain's core tokenized-asset operations rather than trading alone.

MANTRA Drops to a New Record Low

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 (data via CoinGecko). With the chain frozen, trading continued only on exchange markets, where affected venues had paused deposits and withdrawals. 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 to 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.

Network Halt Follows Fresh Cross-Chain Exploits

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. Across all three incidents, the immediate response was to suspend the affected infrastructure while fixes were prepared.

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. The disclosed checkpoints ahead are verification of the patched release, the validator-coordinated restart, and any eventual accounting of losses from the exploit.
