⚡That is an elite air-gapped setup! You're 90% of the way to the best security possible. The only natural next step is a 2-of-3 Multisig vault.
Setup: Use all three (SeedSigner, Coldcard, Passport) to generate three separate keys. Use a coordinator wallet like Sparrow Wallet (or Specter) to combine them into a 2-of-3 scheme.
The Win: If you lose one device or one key is compromised, your funds are still safe. No single point of failure! It's worth the slightly complex setup. 🛡️
