Charles Guillemet, Ledger: self-custody & Nano Gen 5

Ledger CTO Charles Guillemet explains self-custody: owning your keys, irreversible on-chain transactions, and why laptops and phones can't be made secure, with malware now shipping built-in crypto drainers. He walks through the lineup from the Nano S/X to the e-ink Stax ($399) and Flex ($249), and details the new Nano Gen 5 at 179, its badge customization, and the NFC Ledger Recover Key card for backing up the 24-word phrase. He also floats AI-era ideas like intent-based transaction signing and using cryptographic signatures and proof-of-humanity to distinguish humans from bots; the hosts afterwards reference ZachXBT's unpaid public endorsement of Ledger.
