In derivatives trading, a contract is an agreement that defines financial rights and obligations linked to an underlying asset, index or other reference. Trading the contract creates contractual exposure; it does not necessarily transfer ownership of the referenced asset.
The specification defines the product
A contract’s terms identify its underlying reference, size or multiplier, quotation method, settlement currency and settlement process. They also establish whether it expires and how margin or other performance obligations work.
Different contract types allocate rights differently. A futures position carries contractual settlement obligations, while an option gives its buyer a specified right and imposes corresponding obligations on the seller if exercised. A perpetual contract can continue without a scheduled expiry, subject to its rules.
One contract is not always one coin
On a trading screen, “contract” can also mean a unit of position size. One unit might represent a fraction of an asset or a fixed amount of quote-currency value. Comparing contract counts without reading the multiplier can therefore misstate exposure.
A financial contract is also distinct from a smart contract, which is executable blockchain code. A derivative may use smart-contract infrastructure, but its economic payoff still depends on the product’s particular terms.
