What many people don't get is that "custodial vs. non-custodial" is NOT about how secure the Bitcoin is that's held by the custodian. It doesn't matter. Think like an autist or a mathematician:

Do you control your Bitcoin, yes or no?

It's not about "how easy can someone collude to steal your Bitcoin that you don't control" or "does the code run in an HSM" or "theft would be detectable". All these things don't matter for this question. They're interesting but that's not the point. You're thinking about the wrong categories, namely *security*, not *custody*.

Words have meaning. Unilateral exit is a necessary condition.

So for Cashu, the answer is sometimes?

No for Cashu it's "no you don't control the Bitcoin"

I see, because the unilateral exit is to Lightning. So is Lightning “sometimes”?

There's no unilateral exit to Lightning unfortunately. It's technically impossible. We don't even have many options for on-chain exit other than Lighting, Ark, and state chains. Maybe bitvm based things but that's still vaporware at this point.

True I should know this. At any point the mint can disable lightning exchange for ecash.

There is unilateral exit in lightning : you can force-close a channel.

I said TO lightning, not from ;)

yes, you can exit from Lightning.

No worries mate. It's an important point.
