MANTRA Chain halted its network after an attacker exploited a software vulnerability.

The incident froze transactions, deposits, withdrawals, and bridge operations.

MANTRA’s token fell to a record low before partially recovering.

MANTRA Chain halted its blockchain after an attacker exploited a vulnerability in an upstream software dependency, freezing transactions, deposits, and withdrawals while developers investigate the incident.

The Layer 1 blockchain built for real-world asset (RWA) tokenization stopped producing blocks at around 11:13 p.m. UTC on Thursday. The incident also affected public endpoints and bridge operations.

MANTRA’s native token fell to a record low of $0.004126 after the network shutdown, before partially recovering. At the time of writing, the token was trading at about $0.004442.

Validators Offline After Software Exploit

MANTRA confirmed the halt in an X post on August 21, saying it had taken the chain offline as a precaution while investigating the incident. All endpoints and transactions were frozen, temporarily affecting deposits and withdrawals on connected exchanges.

“We're aware of an incident affecting MANTRA Chain and have halted the chain as a precaution while we investigate. All endpoints and transactions are currently frozen. This means deposits and withdrawals to/from MANTRA Chain are temporarily affected. If you're unsure how this…” — MANTRA | The EVM L1 for RWAs (@MANTRA_Chain) August 21, 2026

An update on MANTRA’s status page said the attacker exploited a vulnerability in an “upstream dependency,” software used by the blockchain but developed outside the network itself.

MANTRA said it had identified the issue and was preparing a patched release.

Validators, the network operators responsible for processing and verifying transactions, remain offline while developers test the fix. Restarting the blockchain will require coordination across the validator set.

The outage has also affected MANTRA’s public endpoints and bridge operations, which connect the network with other blockchains. That means the immediate impact extends beyond block production to the tools users and exchanges rely on for network access and asset transfers.

MANTRA has not disclosed which software was exploited, how the attack was carried out, or whether any assets were stolen.

MANTRA Token Price Falls

The network halt triggered renewed selling pressure on MANTRA’s token, which fell 18.6% from its 24-hour high to reach $0.004126 before recovering part of the decline.

The token remains more than 83% below its March 2026 record high of $0.02627, based on the price figures cited above.

The latest sell-off comes more than a year after MANTRA’s token suffered a much larger market shock in April 2025, when its value fell more than 90% within hours.

MANTRA attributed that earlier collapse to forced liquidations of large leveraged positions and rejected allegations that an insider sale had caused the decline.

MANTRA has positioned itself as a blockchain focused on the tokenization of real-world assets, or RWAs, and has pursued partnerships aimed at institutional adoption. For projects in that segment, operational stability is especially important because the systems are designed to support asset transfer, exchange connectivity, and other functions that users and counterparties may need to remain predictable.

The company has not provided a timeline for restoring normal service, and the next development to watch is whether the patched release can be deployed and validator coordination completed without additional disruption.
