External Functions

External Marketplace Contract Functions
External functions in Solidity serve as defined entry points for other contracts and external entities to interact with a smart contract. These functions allow for communication and integration between contracts, enabling the exchange of data and triggering specific actions. By leveraging external functions, developers can create interoperable smart contracts that interact seamlessly with the wider blockchain ecosystem.
In the following sections, we will explore the various external functions available in our marketplace contract and provide detailed documentation on their usage, parameters, and return values. Gain a deeper understanding of how to utilize these functions to enhance the functionality and interconnectivity of your smart contracts.
