- For those outside of Paris, registering for the livestream is the only way to catch the announcements as they happen.

This year AI started acting for you, inside software it can outsmart.

AI Is Already Acting on Your Behalf
AI agents read inboxes, browse the web, and increasingly act without a human confirming each step. The devices carrying out this shift, your everyday phone or laptop, were built for convenience and connectivity, not for resisting a system designed to fool them.
When software can be tricked, when AI makes it even easier for you to accidentally get scammed or lose access to the things you own and cherish, a Ledger signer provides a shield of approval, a physical root of trust. Whoever controls the code running on a device controls what that device’s screen displays. If an agent operates through the same general-purpose system it’s meant to be checked by, that check means very little.
Ledger Op3n 2026 will explore where that final say should live: what gets verified, and where it gets verified.
