Long description

A Call Option Contract is a derivative product and is a right but not an obligation to buy a commodity, currency, or other instruments at a predetermined price at a specified time in the future.

Opium.Exchange offers several of its trading products in the form of a Call Option Contract with crypto cash settlement.

Option contracts do not require traders to post 100% of collateral as margin, because of this you can trade with leverage of up to 100x on some Opium.Exchange contracts.

All margin on Opium.Exchange is denominated in stable coins or any ERC20 coins, allowing traders to speculate on the future value of its products only using stable cryptocurrency or other Ethereum based tokens.

"European style" means options cannot be exercised before expiration, but can only be exercised at expiration.

"Cash settled" means when a cash settled option is exercised the writer of the contract pays any profit due to the holder in stable coins (or any ERC20 coins specified in the contract) rather than any asset transfer taking place.
