Editorial assessment
In this direct comparison, Ledger Flex and Ledger Stax are two premium hardware wallets with touch displays from the Ledger ecosystem. Both offer USB, Bluetooth and NFC; Secure Element and Seedphrase backup are documented, SLIP39 is missing. Open source firmware is not shown in the catalog for either - if you prioritize that, compare other brands. The features table shows form factor, assets and MSRP; List prices are not a guarantee of an offer.
Ledger Flex combines touch controls in a more compact body than Stax. Multi-asset according to the catalog: Bitcoin, Ethereum/EVM, Solana. Air gap missing; Signature runs via Ledger Live. MSRP EUR 249 — the lower list price in this pair. If you want touch and mobile signature without buying the largest display, read Flex more closely. Profile: Ledger Flex.
Ledger Stax relies on a larger touch display in a curved design - connection profile identical (USB · Bluetooth · NFC). RRP EUR 399. Differences lie in form factor, display size and price, not in a fundamentally different security architecture. If you prioritize a portfolio or NFT overview on the device, compare Stax - still Ledger live workflow, no air gap. Details: Ledger Stax.
No ranking: Flex for touch premium with lower MSRP; Stax for maximum display and design - scenario and budget decide, not brand loyalty alone.
