Risk and custody

Two questions matter more than any other in a product like this: how much can this cost me, and who can move my money. Both have exact answers.

What you can lose

You can never lose more than you put in.

Every copy is an isolated margin position. One bad trade cannot reach the rest of your account. The most a copy can cost you is the margin you chose for it, and that number is printed on the ticket before you commit to anything.

Exits are armed at entry

Callers rarely post their sells. So Rubick does not wait for them: your take profit and your stop loss are attached the moment the position opens, and they close it for you whether or not the caller ever follows up.

Custody and keys

Your funds sit in your own account on Hyperliquid.

Trading runs through an agent key that can only trade. It cannot withdraw, and it cannot change where money goes. Withdrawals are signed by your master key alone, to your own wallet alone.

That is the whole security model in one line: Rubick cannot move your funds, and neither can a compromised agent key.

If Rubick is not there

Because the account is yours, you are never dependent on us to reach it. If Rubick is unavailable for any reason, go to Hyperliquid directly and close, adjust or withdraw on your own. Full detail in the failsafe.
