Long or short, up to 5x.

Post ETH margin from your wallet. The mark is the Uniswap pool. A 5x position liquidates after a 20% move, and you cannot lose more than the margin.

The first signature publishes the margin contract from your wallet. Fern has no key that can withdraw it.

Portfolio

Your balances land here.

Connect a Robinhood Chain wallet and this card reads ETH, USDG, and the tokens you hold.

Up to 5x

Long or short. A 5x long liquidates if the pool mark falls 20%. A 5x short liquidates if it rises 20%.

Loss stops at the margin

The ETH you post is the most that position can lose. Profit is paid only from liquidity in the margin contract.

Spot is still there

Buy or sell the token itself with ETH or USDG. That swap is signed to Uniswap and lands in your wallet.
