Currently, USDT, BTC, ETH, and XRP are accepted. Regardless of the instrument type, you can use your assets as a margin deposit for orders. (e.g., Buying BTC futures with XRP deposit)

However, all transactions are settled based on USDT. If you don't have USDT deposit, then the deficit amount will be automatically exchanged to USDT at the market rate when the position is closed. (depending on the market volatility, 90-95% of the market price).

0.1% of the underlying or $0.01 whichever is greater for the Futures, and 2.5% of the price of options or $0.01 whichever is greater for option products.

Maker order (post order) rebate is available by requests for the users who have at least $1M USD per day trading volume.

2.5% of the settlement amount at maturity.

We use the spot prices from Crypto Compare to ensure clarity of the settlement process and make sure we have no influence over the index.

All your position will be automatically liquidated if your estimated balance is lower than the total sum of maintenance margin.

Deposits other than USDT will be valued 90-95% of their spot price considering their market volatility and market correlation when losses are settled.

A futures contract is a legal agreement to buy or sell a particular commodity or asset at a predetermined price at a specified time in the future. Futures contracts are standardized for quality and quantity to facilitate trading on a futures exchange.

The buyer of a futures contract is taking on the obligation to buy the underlying asset when the futures contract expires. The seller of the futures contract is taking on the obligation to provide the underlying asset at the expiration date.

However, you can always clear your obligation before the expiration date by taking the opposite position on the market.

An options contract is a type of investment that gives you the right but not the obligation to make a trade in an underlying asset.

Options contracts have specified expiration dates and the price, known as the strike price. You can choose whether to exercise your option on the expiration date or simply allow the option to expire unexercised.

Call option is the right to purchase the underlying asset and Put option is the right to sell the underlying asset. All options traded in Option Pool are European style vanila option which you can exercise only on the expiration date.
