What Rubick is
Rubick is a copy trading app. It watches crypto traders on X, reads the calls they make in public, and turns those calls into trades sized by rules you set in advance. Those trades execute on Hyperliquid, from a wallet that belongs to you.
The pitch is time. If you want exposure to what good callers are doing but you do not want to sit in front of a feed, a terminal and a chart all day, Rubick does the watching and the executing for you.
The three pieces
Section titled “The three pieces”The feed. Rubick monitors a roster of trader accounts on X. When one of them posts a call, that post becomes a signal: which asset, which direction, and the words that produced it. Nothing is hidden behind a summary. You can always read the post the trade came from.
Strategies. A strategy is a group of traders plus your settings. You choose the size, the leverage, the take profit and the stop loss. When a trader in that strategy makes a call, your rules turn it into a position. You can also run a strategy in Counter mode, which takes the other side of what a trader calls.
The terminal. Everything a strategy does lands in a normal trading account you can drive yourself. Open, adjust or close positions by hand at any time.
What Rubick does not do
Section titled “What Rubick does not do”- It does not take custody of your funds. Money stays in your own wallet on Hyperliquid, and you can reach it there directly even if Rubick is not working. See the failsafe.
- It does not set your leverage or your boost. Both are yours to choose, never inherited from the trader you are copying.
- It cannot withdraw your money. Trading runs through an agent key that can only trade. Withdrawals are signed by your master key alone. See Risk and custody.
- It does not silently change your open positions when you edit a strategy. Settings changes apply to future trades, and anything already open stays under the terms it opened with.
- It does not require the traders to participate. Callers are read from their public posts. They do not configure anything on your behalf.
Using Rubick is free. Revenue comes from a builder fee attached to the trades it executes, so there is no subscription and no charge for the app itself. See Fees for the numbers.
