Ledger CTO Charles Guimet: Self-Custody & the Nano Gen 5

After a Fora ad and audio issues, Ledger CTO Charles Guimet explains self-custody: keys stored on phones or laptops are exposed to malware and crypto-drainers, so hardware wallets keep keys off-device and let users verify what they're signing. He walks through the device lineup — the Nano, Stax, and Flex — and the new $179 Nano Gen 5, with personalization badges and the NFC Ledger Recovery Key backup card. He also covers Ledger's patented R&D toward secure phone-based wallets and ideas like signing content and proof-of-humanity to counter bots in the AI era.
