Cosmos Hub, the main blockchain supporting the ATOM token, has resumed operation after a network stall. However, users who hold ATOM through a Ledger hardware wallet still cannot view their balances, review transaction history, or send transactions through Ledger Wallet.

The situation highlights the difference between recovery of the underlying blockchain and restoration of wallet software that reads and interacts with that network.

Cosmos Hub resumes after network stall

Cosmos Mainnet appeared to stall at block 32,878,318, according to infrastructure provider QuickNode, which reported the issue on September 8, 2026, at 18:12 UTC. The timestamp indicates when QuickNode flagged the problem and does not establish the exact moment the chain stopped.

QuickNode said its nodes had recovered and were back at the chain tip by September 9, 2026, at 14:26 UTC. This meant its servers were again processing the latest blocks on the network.

QuickNode reported the incident as resolved on September 12, 2026, at 00:24 UTC. The provider said the fix followed direct communication with Cosmos Labs and linked to a Cosmos Labs post concerning the binary package used to resolve the incident. The report did not disclose the contents of that package.

“Our nodes have recovered and are back at the chain tip. We are continuing to monitor the situation and will provide further updates as needed.” — QuickNode incident response team, via its incident report

The restart of the network does not necessarily restore every application that depends on it. In this case, Cosmos Hub recovered while Ledger’s wallet-related services for ATOM remained unavailable. A similar distinction arose when Cosmos disclosed a SagaEVM exploit as a patch shipped and users had to wait for the software side to catch up.

Ledger Wallet continues to report an ATOM service disruption

Ledger, the company behind its hardware wallets, opened a Cosmos (ATOM) Mainnet service-disruption incident on September 8, 2026, at 19:41 CEST, or 17:41 UTC. Ledger identified the affected component as Ledger Explorers (Cosmos (ATOM)), the service that reads blockchain data for the wallet.

The disruption affects several functions. Ledger Wallet cannot display ATOM balances or transaction history, and users cannot send ATOM transactions through the wallet. Ledger’s initial notice also warned that adding accounts could be affected.

In its most recent update, dated September 10, 2026, at 16:12 CEST, or 14:12 UTC, Ledger said restoration work was continuing while the features remained unavailable. The incident was still classified as “Identified” as of September 13, 2026.

“Our team is continuing to work on restoring Cosmos (ATOM) Mainnet service. Balances, transaction history, and transactions for Cosmos (ATOM) remain unavailable in Ledger Wallet in the meantime.” — Ledger incident response team, on its status page

Ledger’s status-page incident is available at

A wallet application failing to display a balance does not by itself indicate that funds have been lost. It means the application is currently unable to read and show the relevant blockchain data. The failure alone does not establish anything about the underlying holdings on the chain.

The available information concerns access to ATOM through Ledger Wallet. It does not point to a hardware fault, a network-wide transaction failure, or an issue affecting other assets. CryptoSlate also reported on September 13, 2026, that Cosmos Hub had recovered while ATOM remained unavailable through Ledger Wallet.

ATOM was trading near $1.61 with a modest 24-hour move. There is no evidence that the Ledger wallet outage caused that price movement. Wallet reliability has been a recurring issue across the crypto sector, including the Lightning Development Kit v0.2.6 node-restart fixes and the current Cosmos-related disruption. Related coverage is available in Lightning Development Kit v0.2.6: Fund-Theft and Node-Restart Fixes.

Recovery timing and cause remain unconfirmed

The available information does not establish when Ledger Wallet will again display ATOM balances or allow users to send transactions. Ledger has not provided a root-cause explanation or an estimated restoration time.

Balance display and transaction sending also require separate confirmation. One function could return before the other, so both must be verified independently once Ledger issues further updates.

The cause of the continuing disruption, the number of affected users, and the availability of a verified fix remain unconfirmed. No specific bug, exploit, or service provider has been identified as the reason for the Ledger outage.

For users who hold ATOM on a Ledger device, the available information supports monitoring Ledger’s official incident page rather than assuming that the inability to view a balance means the funds are missing. The broader context includes other crypto infrastructure incidents, such as the Chainflip TRON exploit, but those events do not establish a connection to the Ledger disruption.
