MANTRA Chain Pauses Mainnet After Suspected Upstream Dependency Exploit

The pause freezes transactions, halts deposits, requires a coordinated patch test, keeps assets locked until engineers confirm a safe restart.

Overview

  • The MANTRA network was halted on Friday, Aug. 21 and stopped producing blocks at block 17,449,398, with validators, public RPC endpoints, bridges and IBC relays frozen.
  • MANTRA’s engineering team and external security partners are investigating an incident the project says likely involves a compromised upstream dependency, though a full public post‑mortem and forensic confirmation are pending.
  • Exchanges including Upbit have suspended MANTRA token deposits and withdrawals while centralized trading continues, and the team has warned users not to engage with recovery offers.
  • The token plunged to a record low near $0.00413 as trading volume spiked roughly 591–600% to about $24 million, intensifying short‑term liquidity stress for holders.
  • A patched client (v8.4.0) is reported to be under test on a testnet and a coordinated validator upgrade is required before mainnet can restart, a process that will determine asset safety and the final recovery timeline; the situation bears extra scrutiny because Inveniam Capital Partners is set to acquire MANTRA in Q3 2026.
