Cashu offers the best privacy for custodial wallets. Custodial wallets make up the vast majority of all wallets in the world. It's not 3D chess. Our plan is pretty obvious.

Liquid is a Blockchain and has a transaction graph, block explorers, etc. Everybody sees which address pays which. Monero has better privacy than Liquid because the transaction graph is "blurred", but still exists. Coinjoins can help here as well. Ecash has no transaction graph at all.

Is there a mint standard operating procedure that verifies their reserves are what they should be? Worries me that mints can cheat.
A random Cashu mint is less trustworthy than the liquid federation. Don't put more than a small spending balance in so you don't get rekt. It's meant for short-term payments and nothing else.
Mints can debase the reserves just like basically every non-ecash custodian can. Ecash can be audited better than an ordinary custodian though, but not as easily as a Blockchain.
It was kinda the common mindset of everyone back when it was introduced a long time ago.
One difference: Liquid hides the amounts, which is great, but as it's a blockchain, the relationship between subsequent transactions is clear to be seen (transaction graph). That's not the case in cashu (ecash).
Currently a wallet is composed of a bunch of nuts that make up your entire balance. We must do this to maintain privacy (all nuts with the same amount look the same to the mint). When we hide the amount, we can store the entire wallet in a single nut while having better privacy than today. Wallets will be less than 1kb in size. We will put them literally everywhere. It will be in-fucking-sane
Cashu uses Lightning for inter-mint payments. A mint likely has better channels than an ordinary user but Lighting remains Lightning. Intra-mint payments always settle instantly.

why does cashu need lightning, my friend (voices in my head) says you don't need it
As long as it’s a free market who cares if it’s custodial or not. The puritans getting all bent out of shape for no reason.
