Hardware-based cryptocurrency wallet provider Ledger has experienced some issues due to massive outflows from crypto exchanges amid the FTX bloodbath, according to its chief technology officer.

Ledger saw a “massive usage” of their platforms and suffered a “few scalability challenges” on Nov. 9, Ledger CTO Charles Guillemet reported in a statement on Twitter.

Guillemet reasoned Ledger’s issues by the outcomes of the ongoing crisis of a major global cryptocurrency exchange, FTX. The CTO said that crypto investors have been increasingly offloading their holdings from crypto exchanges to Ledger, stating:

“​​​​After the FTX earthquake, there’s a massive outflow from exchanges to Ledger security and self sovereignty solutions.”

According to Guillemet, Ledger should have resolved the outages as of 5:30 am UTC.

Ledger first reported the wallet issues on Nov. 9 at around 11:00 pm UTC, officially announcing that its hardware wallet interface application Ledger Live was experiencing downgraded server performance.

“Specific issues may vary, including connecting to the My Ledger tab and performing a Genuine Check,” Ledger said in a tweet, adding that the client’s assets were safe.

The hard wallet company subsequently took to Twitter to announce that it fixed the server outage in about one hour after detecting the issue. “Our server outage has been resolved and all systems are operational,” Ledger said, adding that their server outage was resolved and all systems were operational.

Previously, Ledger Support also announced that it also temporarily paused FTX and FTX.US swaps on Ledger Live. Ledger launched the swap integration with FTX in July 2022.

According to Ledger’s Twitter thread, the outages caused some users to be unable to send any transactions using Ledger Live, including withdrawals.

The crypto community was quick to react to the issues despite many staying confident about Ledger’s operations amid the larger market issues. Some industry observers criticized Ledger for choosing the wrong wording to communicate with their customers amid the ongoing issues at FTX. People apparently got triggered by Ledger’s wording “assets are safe” as FTX founder Sam Bankman-Fried made a similar statement on Twitter on Nov. 7, only to delete it a day after.

“FTX is fine. Assets are fine,” Bankman-Fried declared in his tweet, just hours before the exchange stopped all crypto withdrawals after becoming unable to process such transactions.

The recent issues on Ledger Live came as Ledger saw one of its “highest traffic days ever,” Ledger CTO told Cointelegraph. “Traffic has increased significantly over time, even without major industry events,” he noted, adding that Ledger also previously saw plenty of traffic spikes after Celsius bankruptcy, the Solana hack as well as the FTX bank run.

Guillemet also said that Ledger Live had an “unusual load on the device manager service,” which is likely to be attributed to users updating their device for the first time in a while or using a brand new device for the first time. “It was quickly resolved and the team is already working on improving automatic detection and restoration,” he added.

A major rival cold wallet provider, Trezor, has not recorded any issues due to the FTX issues so far, Trezor executive Josef Tětek told Cointelegraph. “The only way to avoid these massive blow-ups is to understand self-custody as a necessity,” the exec stated. “Not an option; a true necessity,” he emphasized.

Despite self custody being associated with its own set of risks, many crypto people, including Tether and Bitfinex CTO Paolo Ardoino, still recommend users “always to self custody in cold storage” if they want to hold their Bitcoin (BTC) and crypto.
