Charles Guillemet, Ledger CTO — AI Agents, Self-Custody & Wallet Security

Author: Bitcoin.com July 18, 2026 Duration: 23:34

🎙️ As AI agents become more capable, who should control your crypto wallet—you or the AI?

Charles Guillemet, CTO of Ledger, joins Alex Richardson at Proof of Talk 2026 to discuss the future of crypto security and why self-custody will become even more important in the age of AI.

Guillemet shares how he got started in hardware security, why Ledger built its underground Dungeon security lab, and how the company stress-tests wallets, chips, and software before attackers can exploit them.

The conversation also explores why AI agents should never have direct access to private keys, how Ledger is approaching AI-powered wallets, and the security challenges posed by quantum computing, side-channel attacks, and the next generation of digital assets.

Topics include:

  • Ledger's Dungeon security lab
  • Hardware wallet security
  • AI agents and wallet safety
  • Self-custody and private key protection
  • Clear signing
  • Quantum and side-channel attacks
  • The future of secure wallet design
