A transitive call occurs when a smart contract interacts with another contract by invoking its functions and that second contract, in turn, calls a third one. This creates a chain of calls, allowing for complex operations to be executed across multiple contracts.For example, Contract A can call Contract B, which then calls Contract C. Each contract performs its designated functions, but the interaction can lead to complications such as gas costs, execution order, and state changes. Understanding transitive calls is important because they can introduce vulnerabilities. If one contract in the chain fails or behaves unexpectedly, it may affect the entire transaction. It’s crucial for developers to design contracts carefully and consider how these interactions can impact security and performance. Overall, transitive calls enable greater functionality in decentralized applications, but they also require careful management to avoid issues.
