A paid contract refers to a contract in which either party has the obligation to pay a certain amount of money while enjoying the rights. Most paid contracts such as sales, leasing, contracting, paid entrustment and paid custody are bilateral contracts.
A gratuitous contract refers to a contract in which one party only enjoys contractual rights without paying any price, also known as a favor contract. Free contract is not a typical transaction form. In practice, there are mainly gift contracts, free loan contracts and free custody contracts.
A unilateral contract, also known as a unilateral contract or a unilateral obligation contract, refers to a contract in which one party only enjoys the right but fails to perform the obligation, while the other party only undertakes the obligation but does not enjoy the right (such as a gift contract, a loan contract for returning the goods and a contract for keeping them free of charge), which corresponds to a two-way contract.
