Adding funds
Funds live in your own trading account, which is a Hyperliquid account controlled by your wallet. Rubick never holds them. Adding funds means moving money into that account, and it is the only step between signing in and trading.
What you can send
Section titled “What you can send”USDC on Arbitrum One. There is no minimum. Send what you want to trade with.
What it costs
Section titled “What it costs”Deposits are free. You pay network gas for the transfer itself and nothing to Rubick. See Fees for the full picture, including what it costs to take money back out.
Funding at the moment you need it
Section titled “Funding at the moment you need it”You do not have to plan ahead. If you are sizing a strategy and your balance cannot cover it, Add funds is available right there, and the strategy picks up the new balance when it lands.
Automatic top ups
Section titled “Automatic top ups”Deposits can be set to move into your trading account on their own as they arrive, so you do not have to confirm each one by hand. This is a setting you turn on, and it is off until you do.
