The Ledger Podcast

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.

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.

Leonard Lin, Founder and CTO of Shisa.ai who builds Japanese language/audio models and secure agent frameworks. He discusses Shisa D, a security‑first agent design that flips control so the system decides, removing secrets and routing high‑risk actions to hardware signing. Talks cover prompt‑injection risks, TextGuard, modular skills, and a live demo of hardware approval for agent actions.

What is a DeFi vault, and how do you use one without handing over control of your money?In this episode of The Ledger Podcast, Ledger’s EVP of Consumer Services JF Rochet sits down with Adrian, co-founder of Steakhouse Financial, a leading on-chain asset manager specializing in institutional-grade DeFi vaults, to break it down from the basics up.The takeaway: do your own research, take it seriously, and when you're ready, sign with a Ledger signer.

Quantum computing is coming for the cryptography that secures payments, messaging, websites, banks and blockchains. But how worried should you actually be, and what should anyone be doing about it?In this new episode of The Ledger Podcast, Ledger CTO Charles Guillemet sits down with Ledger Head of Brand Development Mo El-Sayed to unpack what's really happening — without the doom.

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.

Rand Hindi, Founder and CEO of Zama, and Charles Guillemet, CTO of Ledger, dive into the crucial topic of privacy in cryptocurrency. They explore how fully homomorphic encryption (FHE) could revolutionize blockchain confidentiality. Rand highlights the need for privacy over mere public verifiability, while Charles discusses the balance between secure hardware and performance. The duo examines the rising demand for confidential tokens and predict that FHE will become as essential for blockchains as HTTPS is for the web.
