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.
