Every privacy tool ships with a list of rules you have to follow.
Don't withdraw the same amount you put in. Don't do it an hour later. Don't reuse the address.
That isn't privacy. That's homework.
On H0 the rules are the contract.
Every amount the chain can see is a whole number of grains 100 USDT0, 0.001 oz of gold and the fee is charged on top of the grain, never out of it. Nothing ever leaves as an odd number, so two withdrawals the same size are just that: the same size.
And a trading desk is funded once, comes home once, and only empty.
You can't use it wrong. It won't let you.
Hyperliquid will tell a contract what your trading account is worth.
It will not tell it what is inside.
On HyperEVM, equity reads. Positions, marks, orders those calls revert.
Every privacy design treats that as a limitation.
It is the whole product.
H0 funds a trading desk out of a shielded note, watches its equity move without ever seeing a position, and takes the money back when it goes flat. The chain can prove the desk came home empty.
It can never prove it was yours.
