Hate can be a powerful tool if you use it as motivation to accomplish something good.
But if you don't direct it as a useful motivator, hate can be a powerful poison that consumes you from within.

Open source vs source viewable is irrelevant in this context: the point is that publishing code by no means guarantees that vulnerabilities will be found in a timely manner.
In the context of Casa, which only generates and stores the mobile key, a malicious app could be deployed to steal keys practically instantly, far faster than any human or machine would catch the malicious code. Having the code available would not change the security model: either you trust Casa to handle the mobile key or you don't, and we offer multiple options that serve both of those models.

2026-08-15 10:28:41 UTC

- reply

If Casa had access to mobile keys then it would make us a custodian, which we're quite careful to avoid becoming since our business isn't set up for it nor do we KYC clients.
Casa open sourcing the app wouldn't guarantee that mobile keys couldn't be stolen, just like how coldcard being open source didn't prevent keys from being stolen.
The only way to guarantee that a malicious Casa app can't steal the mobile key is to swap it for a hardware key so that the app never has access.

2026-08-15 01:22:49 UTC

- reply

If you're worried about a malicious Casa app stealing the mobile key then you can opt to use a second hardware key in lieu of the mobile key. What you lose is the automatic encrypted key backup.
