Reimagining bitcoin hardware wallets with SeedSigner

In this episode, we compare common hardware wallets with SeedSigner, a DIY bitcoin hardware wallet. We explore the reasons behind building SeedSigner, the process of securely generating seeds, and the considerations for holding a private key on hot devices like an iPhone or cold devices like a Trezor, Ledger, or Coldcard. We also discuss the evolution of bitcoin custody over the last decade, the risks associated with using common hardware like Raspberry Pi, and the advantages of multisig versus singlesig setups.

Awesome interview. Open source the world

Thanks! And yes 100%.

Why call it a "signing device"? Because that's a much more descriptive name than the misleading term "wallet." The BTC aren't inside like cash in a wallet. And the case is even stronger for any device that doesn't even store the private key inside.

There is a huge need for a reliable and bonded service to set up boomers' BTC savings. Unchained's position would be perfect, but they would have to figure a way to limit liability, which seems to be a huge issue- how can an owner truly TRUST that third party?
