Validators were told to keep nodes offline after an issue affecting the chain's EVM compatibility layer, with the token dropping over 18% to a new all-time low.
<p>The MANTRA blockchain, built using the Cosmos SDK, was halted on August 21 after an incident affecting its Cosmos EVM module, with the project instructing validators to keep their nodes offline while engineers worked through the issue.</p>
<p>The Cosmos EVM module allows a Cosmos-based chain to run Ethereum-compatible smart contracts, giving developers access to Ethereum's broader tooling and application ecosystem while still operating within the Cosmos framework and its interchain communication capabilities. An incident affecting that specific module suggests the problem was tied to how MANTRA's chain processes Ethereum-compatible transactions or contract execution, rather than a more fundamental failure of its underlying Cosmos-based consensus mechanism.</p>
<p>The MANTRA team stated that no user funds were exploited as a result of the incident, distinguishing it from a malicious hack or theft. Instead, the halt appears to reflect a technical fault serious enough to warrant freezing all transactions and staking activity network-wide while the team develops and tests a patched software release before attempting to restart the mainnet -- a standard, conservative response for blockchain networks facing a bug with unclear scope, prioritizing preventing further complications over resuming activity quickly.</p>
<p>Despite the team's assurance that funds remain safe, the incident hit MANTRA's native token hard, with the price dropping more than 18% to a new all-time low following the halt announcement. That kind of sharp price reaction is a common pattern following network halts, even when no funds are directly at risk, since an extended outage raises broader questions about a network's reliability and can trigger risk-averse selling from holders uncertain how long normal operations might be disrupted.</p>
<p>MANTRA has not provided a specific timeline for when mainnet operations might resume, saying only that a patched release is being tested. The incident adds to a difficult recent stretch for the project, whose token has faced significant price pressure over the past year following an earlier, unrelated period of volatility -- making this latest technical halt a further setback for a network that had already been working to rebuild market confidence heading into the second half of 2026.</p>
