Review
Ledger Flex
Popular hardware wallet with closed-source firmware
Our Verdict
Polished hardware and a good mobile app, but Ledger's closed-source firmware and the 2023 Recover controversy raised real questions about the trust model. Three data breaches and a supply chain attack compound the trust issues. Still a reasonable option for casual holders, but not our top pick.
What we like
- Strongest Secure Element chip (EAL6+, ANSSI certified - unique in market)
- E-ink touchscreen display
- Strong mobile app (Ledger Live)
- Bluetooth connectivity for mobile use
- Wide third-party app ecosystem
- 6.5M+ units sold - largest install base
What could be better
- Closed-source firmware - cannot be independently verified
- 2023 Recover controversy proved firmware can extract keys from device
- Premium price ($249) plus optional $9.99/mo Recover subscription
- Three customer data exposures (2020 breach, Shopify incident, 2026 Global-e)
- December 2023 Connect Kit supply chain attack ($600K stolen)
- Supports altcoins (broader attack surface)
- Ex-CEO admitted "false sense of trustlessness" about prior security claims
How We Scored This
Community score compiled from Reddit threads, expert reviews, and app store ratings.
The Recover announcement triggered a mass exodus thread. Top comments: "This proves the firmware can extract your seed." Thousands of upvotes. Many users announced switching to Trezor or Coldcard.
Ledger recommendations have dropped sharply since 2023. Most top-voted replies actively warn against Ledger for anyone who values self-custody principles. "Not your keys" sentiment dominates.
Over 1 million customer emails and 272,000 physical addresses leaked. Led to phishing campaigns and physical threats against users. Ledger acknowledged and published a post-mortem.
Malicious code injected into the Ledger Connect Kit NPM package, draining $600K from DeFi users. Affected third-party dApps, not Ledger devices directly - but damaged ecosystem trust.
App itself receives reasonable ratings (4.1/5 on iOS). Common praise: clean interface, easy to buy/sell. Common complaints: customer support is poor, sync issues, and "why does a hardware wallet need a subscription?"
