MANTRA2026-08-21 14:50:51MANTRA Halts Its Layer 1 Chain, Points to Cosmos EVM Module as CauseMANTRA froze its Layer 1 blockchain late on Aug. 20 after what the team described as an incident in the Cosmos EVM module of MANTRA Chain. All endpoints and transactions were halted, and the network was still offline as of Friday morning. About nine and a half hours after the first notice, the team said it had identified the root cause, contained the threat, and determined that the issue affected two MANTRA-managed wallet addresses. The company said it had no indication that user, exchange, or partner funds were impacted, and added that no user funds were exploited. The outage hit infrastructure positioned for regulated real-world asset settlement. MANTRA has said Securitize, the tokenization platform behind BlackRock’s BUIDL, joined its active validator set in May. The chain also hosts mantraUSD, which MANTRA says is backed by short-term U.S. Treasuries, as well as a Layer 2 that uses MANTRA’s security. The halt came while Inveniam Capital Partners was still working to complete its planned acquisition of the company. Market data showed the MANTRA token hit an all-time low shortly before the halt was disclosed. At the same time, the chain had relatively little onchain value at stake based on tracked DeFi TVL. MANTRA said it is testing a patched release on its DuKong testnet and coordinating a restart with validator partners, but has not committed to a restart time.610

The company said the issue was limited to its Cosmos EVM module, affected two wallet addresses before the chain went down, and did not lead to user funds being exploited. MANTRA also described the chain halt and the upcoming patch as precautionary measures aimed at reducing further risk to users and on-chain assets. The team is now testing a fix and said the network could resume today if those tests go well, with a full postmortem to follow.1140
