AirGapped Hardware Wallets

Regarding the secure elements. They have always been a black-box chip. It was never trustless, regardless if the HW was open or closed-source. The only thing that has changed now after Ledger's revelations is that we know that secure elements allow for remote sending of secrets.   

You are completely right, man.That is why the multisig wallet which requires at least two cosigners from wallets which use those  black-box chips produced by different makers is considered to be more safe haven for the stash in bitcoins than just, let's say, a single hardware wallet regardless the reputation of its manufacturer.

You are completely right, man.

After thinking about it, I should clarify the previous post. It's actually not from the secure elements that the secrets get sent from. The code retrieves the keys, encrypts them, and divides them into shards. Those shards are then sent over the internet to 3 third-parties. Ultimately, it doesn't really matter to the end user. The point is that private data that was never supposed to be online now can.

SeedSigner.  Buy it fully assembled if you don't feel comfortable doing it yourself.  Use it with BlueWallet.  Both are 100% open source.  Why tie yourself to a company that you'll have to trust?

Best of all, if you someday change your mind, you can just buy a different wallet and import your seed.  You won't need to make a new seed & move your coins again because, with SeedSigner and BlueWallet, your seed won't have been exposed to a company that went dirty like Ledger is doing.

If you're waiting for a reply everyone can agree on, you're never going to get one.  Some people are followers and feel like they need to trust a company.  To me, that's bizarre.

Passport is probably one of the best air gapped hardware wallet options right now.
It is better built quality than Keystone, you can easily remove battery and you have clean open source code that works only for Bitcoin.

SeedSigner.  Buy it fully assembled if you don't feel comfortable doing it yourself.  Use it with BlueWallet.  Both are 100% open source.

Seedsigner is not bad but I still consider it as experimental device, and Bluewallet code can't be verified and reproduced, as far as I know.
For any newbie or beginner I would not suggest seedsigner for various reasons, but it's nice to use it in some multisig setup.

True. The latest version that WalletScrutiny tested was 6.4.8, and they weren't able to build it from the provided source. Blue Wallet's latest app version is 6.4.10, released a few days ago. The latest versions that WalletScrutiny were able to reproduce from source were 6.4.5 and 6.4.4.
