Get ETH onto Arbitrum
bring one asset, trade every pad
Coins here are priced in ETH, ARB, USDC, rHOOD, rAAPL or rSPCX, and ETH on Arbitrum is what you bring whichever one you trade. It pays for gas, which is cents rather than dollars here. Each coin settles in the token it bonds against, and the app wraps or swaps your ETH into it as part of the trade, so ETH alone covers every coin on the board.
rHOOD, rAAPL, rSPCX are tokenized equities rather than plain crypto tokens. Trading on those pads still needs nothing but ETH, and the swap runs through USDC because none of them has a market against ETH worth using. What holding one costs you is set out on the how page, and it is worth reading before you buy on one.
