Ledger has stated that the vulnerable version of its Ethereum app had already been patched before the exploit tied to it occurred, placing the timing of the fix, rather than the size of any loss, at the center of the story. For Bitcoin holders who use the same hardware to secure their coins, the episode is a reminder that wallet firmware, not the chain itself, is the surface most attackers probe.
The core of Ledger's position is a chronology claim: the weakness lived in its Ethereum app, and a patched version was released before the exploit took place. The statement is scoped to the Ethereum application specifically, not to the broader Ethereum network or to Bitcoin custody on the same devices.

Ledger's Ethereum app is maintained as an open-source project, and its version history is public. The tagged release list is where the sequence of app versions can be traced, which is the record that any patch-before-exploit claim ultimately has to be checked against. Bitcoin self-custody advocates who follow hardening efforts such as StarkWare's work on a quantum-resistant Bitcoin transaction already treat verifiable, open code as the baseline for trusting a wallet.
A vulnerability being discovered and an exploit being carried out are two separate events, sometimes separated by weeks. When a patch is available before an exploit, the question shifts from whether a fix existed to whether users installed it in time.

Patch availability does not by itself mean every user was protected. Hardware wallet apps require the owner to update through the manager software, and any user still running the older Ethereum app would remain exposed until they did. On that reasoning, exposure here should be treated as conditional rather than settled.
The relevant fix appears in Ledger's version tags, including the 1.22.2 release in the app-ethereum repository. Confirming which specific version closed the flaw, and when it shipped, is the detail that turns Ledger's claim from an assertion into a verifiable timeline. Beyond that release record and the attribution to Ledger, the available evidence does not establish attacker identity, losses, or root cause, and this article asserts none.
The open follow-up questions are narrow and concrete: which app versions were affected, and exactly when the fix reached users. Those two data points determine how wide the window of real exposure actually was.
Incidents involving wallet software also test trust and disclosure practices, because the security promise of a hardware wallet rests on transparent, timely communication when something goes wrong. That scrutiny is not unique to altcoin tooling; the same devices are marketed heavily for Bitcoin self-custody, a theme that runs alongside broader confidence signals like renewed corporate Bitcoin buying and shifting exchange demand visible in the Coinbase premium turning positive.
None of this changes Bitcoin's base layer, which continues to advance on its own cadence through difficulty epochs and steady hashrate growth regardless of application-level flaws in third-party wallet software. The lesson for holders is at the device layer: keep firmware and coin apps current, since the ledger of record on-chain is only as safe as the tool signing the transaction.
