why not just build your own cold wallet? All it needs is a simple USB, practical and does not catch unnecessary attention @DarthCoin has a great guide for that.

All these tools seem really cool and overcomplicated things somehow, and maybe you might want to minimize dependence on any companies?

If you're going Multisig, then we'd highly recommend the SeedQR route. It adds security, drastically reduces complexity and also means you don't need to buy/learn/use multiple hardware wallets.

Others have mentioned the SeedSigner which is fantastic and also avoids supply chain risks... but if you don't want to build it yourself the Blockstream Jade is great too. The Foundation Passport is gorgeous and super great quality, but more expensive than the Jade. Passport doesn't fully support SeedQR (yet) but will soon.

Basically using SeedQR means you can just use the SeedSigner / Jade as a temporary signer. If you have a 2-of-3 multisig you have have 3 QR codes and that's it. That's all you ever need to remember or protect. No PINs, no HWWs to care about. Just the QR codes (and the multisig descriptor file of course).

So a 2-of-3 setup might look like:

If you want to send funds, you create your transaction then to sign it you grab your Jade, scan in a QR code, sign it, then turn it off, grab and scan the second QR code, sign it and it's good to broadcast!

If you don't want to go the SeedQR route, then our top recommendations are:

I'd say if you're really going for the multisig/psbt feature, go for the passport. Using microSD cards is super cumbersome and CC's open source grifting isn't something I would support. If not, I'd suggest taking a look at the BitBox02.

You might want to look into Anti-Klepto rather than "airgapped", which fixes actual security issues compared to made up security benefits.

I will always say:

And I can prove it. Please try to open this wallet:

Foundation Passport ticks all your boxes. I would advice looking deeply into it, I would expect you to love it.

SeedSigner

Nothing else.

100% the Blockstream Jade is the best bang-for-buck hww. 10% off using the aforementioned link:

Blockstream Jade can also be built using compatible HW and there are instructions on their Github repo for doing that. I guess DIY might not be everyone's choice. It can be quite rewarding to learn how to build with components.

I've not heard anything said on Trezor's new model yet.

As already mentioned by others: Seedsigner is the go-to wallet if you value security and transparency in the code. The lack of a dedicated secure element is seen as a feature, since the device is completely stateless and heavily based on the SeedQR standard to quickly import seeds, being them smple ones or part of a multi-sig setup. Then, the fact that it's air-gapped adds extra security, something that I never liked about Trezor and Ledger, for example.

Another big plus: it's extremely funny to build a Seedsigner from scratch, and it's a very nice educational activity that you can do together with friends. Great for orangepilling ;)

Blockstream JADE

Another one is I heard about SATslink I don't know much about it but always DYOR

I actually just entered a competition for the new X1 SafePal bluetooth wallet.
