The MANTRA blockchain has been halted since Thursday night after developers traced a security exploit to a vulnerability in an upstream software dependency, freezing all on-chain activity and sending the OM token to a record low.
The network stopped producing blocks at 11:13 PM UTC on August 20, shortly after the OM token dropped 18.5 percent from $0.005060 to an intraday low of $0.004126, according to data from CoinMarketCap. Trading volume surged nearly 600 percent as panic selling gripped the market. The token, which powers the Layer 1 chain focused on real-world asset tokenization, partially recovered but remained under heavy pressure.
MANTRA issued its first public statement at 11:44 PM UTC, declaring the chain had stopped operating and that all endpoints were blocked. The team described the halt as a precautionary measure while investigators traced the exploit to a vulnerability in an upstream software dependency used by the chain. Within hours, the team confirmed that two wallet addresses were affected but said no user funds were stolen in the incident.
Validators Await Patch Testing Before Restart
Developers released a patched version of the network software designated v8.4.0 and began running tests on the DuKong testnet. A mainnet restart requires two conditions: the patch must pass all testnet checks without issues, and the broader validator set must coordinate a simultaneous upgrade. Until that happens, validators have been instructed to keep mainnet nodes offline, according to MANTRA official update posted on X.
The outage halted not just token transfers but the entire infrastructure layer, including transaction settlement, bridge activity, and public chain access. Deposits and withdrawals of OM remained suspended on affected exchanges throughout the downtime, according to reports from CryptoSlate and CryptoPotato. Futures data showed elevated risk premiums on OM as traders priced in uncertainty around the restart timeline.
Troubled Track Record Raises Questions
The incident compounds a difficult history for the MANTRA project. In March 2026, the protocol completed a one-for-four token split to restructure its tokenomics. Before that, in April 2025, the original OM token crashed more than 90 percent in minutes during a flash event that wiped billions from its market capitalization. The repeated disruptions have raised questions about the resilience of newer Layer 1 chains built on Cosmos-based technology.
The halt also affected MANTRA ecosystem of decentralized applications and institutional partners. Inveniam, which invested $20 million in MANTRA during August 2025, had been working with the protocol on real-world asset settlement infrastructure. The outage raises questions about service continuity for partners relying on the chain for daily operations.
The blockchain halt comes during a week of strong performance across broader crypto markets. Bitcoin surged 22 percent to around $77,000 for its best weekly gain since 2023, while spot Bitcoin and Ether ETFs drew record institutional inflows. Despite that momentum, the MANTRA outage serves as a reminder that security vulnerabilities remain a persistent risk across the Layer 1 landscape, even as institutional capital continues to flow into the sector.
