Defending Against AI Agents with Oded Blatman Nov 02, 2026

Show notes

What does security look like when one attacker can run thousands of AI agents? Sébastien Badault, EVP Ledger Enterprise, sits down with Oded Blatman, Ledger’s Chief Information Officer and Chief Security Officer, to talk about defending against AI-driven attacks, how regulators are approaching AI risk, why banks keep their keys in hardware, and how a supply chain gets secured from the first chip to the end user.

AI Made Security Flaws Cheap to Find. What Now? Sep 14, 2026

Show notes

Security used to depend on flaws being expensive to find. AI made them cheap.

High-severity vulnerabilities flagged in 2026 are already six times the previous four-year average, and breaches are trending up on a multi-year horizon. Ledger CTO Charles Guillemet sits down with Mo El-Sayed, Head of Brand Development, on what that does to the threat model, why secure hardware holds where connected software folds, and the ethics of finding bugs at machine speed.

They close on where this goes next, and what people can do about it now rather than in five years.

How AI Agents Get Paid on Solana Without Touching Private Keys Aug 25, 2026

Show notes

Agents can now complete tasks, write code and get paid on Solana. The part that shouldn't change: humans retaining final control over the assets.

Ian Rogers, Chief Human Agency Officer at Ledger, sits down with Pavel, co-founder of AgenC — a marketplace where agents claim jobs and submit results.

The design starts from one assumption: the host machine is compromised. Agents build and drive transaction flows, but never touch private keys. The Ledger device acts as a supervised signer, not a blind one, connected through Ledger's Device Management Kit.

How to Fix the Security Flaw Built Into Every AI Agent | The Ledger Podcast ft. Shisa.ai Jun 25, 2026

Show notes

AI agents are capable and easily fooled at the same time. They can read your data, act on your behalf, and reach the outside world. Because LLMs don't fundamentally separate data from instructions, anything they read can be treated as a command.

In this episode of The Ledger Podcast, Leonard Lin, CTO of Shisa.ai, in conversation with Ledger Chief Human Agency Officer Ian Rogers, talks about building AI agents you can trust. Leonard's framework, Shisa D, inverts the usual control plane so the AI proposes and the system decides. Secrets are removed from the model, tool calls are reviewed by a separate layer, and the highest-risk actions route to a Ledger signer, where you see the real intent in plain text and approve it with a physical tap.

Plus a live demo of Shisa D routing an action to a Ledger signer for hardware approval.

AI Agent With a Wallet. What Could Go Wrong? Feb 13, 2026

Show notes

In this episode of the Ledger Podcast, the team dives into the rise of the “agentic world” — a future where AI agents act on your behalf to move funds, sign transactions, and manage digital identity. But as agents become more autonomous, one critical question emerges: how do you trust them with your secrets, identity, and wealth?

Fresh from the Circle USDC hackathon, Ledger engineers share how they built a secure bridge between AI automation and hardware-backed security using Moltbook — a platform designed specifically for agent interactions. Their solution enables AI agents to create transaction “intents” that require human approval on a Ledger device, keeping private keys protected inside the secure element.

The episode also unpacks a real-world lesson in AI risk: when the OpenClaw agent over-optimized for hackathon votes, it spiraled into a cascade of failed jobs after hitting rate limits — proving exactly why “human in the loop” guardrails are essential for agentic commerce.
