Morphology
The noun is directly compositional: 'unilateral' means one-sided and 'contract' means an agreement, so a B1 learner who knows both words can infer it refers to an agreement in which only one party makes a promise. It is a technical/legal term, but the core meaning is transparent and predictable from its constituents.
Etymology
Unilateral contract is like a public reward poster: someone promises to pay if anyone returns a lost dog, and the promise is only accepted when a person does the act. The word unilateral means 'one side' and the contract is the 'promise', so it means an agreement where only one party makes the promise and the other accepts by performing the act.
