Unchained:
* Bitcoin only
* I've met a number of Unchained folks (MANY of whom are @npub17tyke9lkgxd98ruyeul6wt3pj3s9uxzgp9hxu5tsenjmweue6sqq4y3mgl maxis!) and consider a bunch of them friends. They are all hard-core Bitcoiners and super-focused on improving self-custody as much as possible.
* Will be moving my self-directed bitcoin IRA over to their service (better match for me vs Swan's IRA product).
* Pricing model: free for basic 2-of-3; $20 each time you need Unchained to co-sign for you (should only be needed in an emergency/catastrophe).
Casa:
* not Bitcoin only. I have a ton of respect for Lopp but since there are various competing services in the market, it's nice that I can choose accordingly.
* Pricing model: Annual fee ($100-200?)
* Fewer personal connections there.
* Overall I just know less about them, to be honest.
Nunchuk:
* Hadn't even occurred to me. Their collaborative custody service is brand new, yes? I would need to see a longer track record before committing any of my stack that way (see below).
* Their early product releases were broken in unacceptable ways (e.g. my cosigner on iOS signed a tx but the app in Android never--to this day--showed the signature as complete. Possibly a problem with which UX flow I used, but still shouldn't be possible to screw that up. Their app has ONE JOB and the early release I tried failed. A subsequent release worked better but was still plagued with some really bad UI/UX decisions: hiding crucial info, not indicating pending txs/balance changes, etc). I love the idea of their app but it'll be a while before I'd feel comfortable deeply integrating any of my multisig setups / cosigners in their ecosystem.
Coming soon (~Oct?): Swan:
* Will def give their service a try when it's available. I want multiple multisigs storing bits of my stack w/different collaborative custody services.
* Bitcoin only
* I have more personal connections to Swan.
* I've worked on and worked closely with the Specter Desktop team, which is now under the Swan umbrella and I'd guess will be the main interface for Swan's collaborative custody service.
