¿Es viable construir una cold wallet casera usando software open-source en vez de comprar un Trezor o Ledger?

He estado mirando hardware wallets como Trezor y Ledger, y vi que muchas de las cosas que usan están basadas en estándares abiertos (BIP32, BIP39, BIP44, etc.). Eso me hizo pensar en algo.

En lugar de comprar una hardware wallet, ¿sería viable crear una cold wallet “casera” usando otro dispositivo?

Por ejemplo:

  • un teléfono viejo que permanezca siempre offline
  • una Raspberry Pi sin conexión de red
  • un notebook antiguo que nunca vuelva a conectarse a internet

La idea sería algo así:

  1. Generar la seed completamente offline
  2. Guardar el backup de la seed en papel o metal
  3. Usar ese dispositivo solo para firmar transacciones
  4. Transferir transacciones sin firmar o firmadas usando QR o microSD
  5. Transmitir la transacción desde otro dispositivo conectado a internet

En teoría suena parecido al modelo de una hardware wallet, excepto que no habría hardware especializado.

Mis dudas:

  • ¿Es realmente viable este enfoque en la práctica?
  • ¿Qué riesgos de seguridad tendría comparado con usar un Trezor o Ledger?
  • ¿Existen proyectos open-source que ya implementen algo parecido?

No estoy pensando en guardar grandes cantidades de cripto. Me interesa más entender el modelo de seguridad y si algo así se puede hacer de forma razonablemente segura.
