SeedSigner is an open-source Bitcoin signing device.

In this episode, SeedSigner breaks down why trustless hardware matters and why Bitcoin security is a journey, not a destination. He explains how hardware wallets have become a “cat-and-mouse” game of exploits and firmware trust, why he chooses to trust math over manufacturers, and how SeedSigner gives users a verifiable, DIY alternative to commercial wallets.

We discuss the evolution of Bitcoin custody, from paper wallets to multisig, and how SeedSigner empowers users to hold keys without relying on opaque supply chains. SeedSigner also shares lessons from his years in digital forensics, why most people’s threat model is themselves, and how open-source sovereignty could become Bitcoin’s last line of defence against capture.
