The Ledger Podcast

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.

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.

In this episode of the Ledger Podcast, Jean-François Rochet (EVP of Consumer Services) sat down with Shah Ramezani, CEO and Founder of Noah, to explore how stablecoins are connecting the traditional finance world with crypto and why payments are the key to real adoption.

Shah explains why stablecoins quietly proved their value during the market downturn, how people were already using them to move money, and what’s been missing to make on-chain and fiat payments work seamlessly together.
