  The 'payable' keyword is used in smart contracts to indicate that a function can receive incoming payments in the form of digital currency. When a function is marked as payable, it means that users can send funds to that function as part of a transaction. This is particularly useful for decentralized applications (DApps) that require users to make payments or transfer funds. By using the 'payable' keyword, developers can ensure that their smart contracts can handle incoming payments and execute the necessary actions accordingly.

  In the context of digital currency transactions, the 'payable' keyword allows users to send funds directly to a specific function within a smart contract. This keyword enables the function to receive and process the incoming payment, triggering the desired actions or functionalities. It essentially serves as a way to interact with the smart contract and initiate transactions by sending digital currency to the designated payable function. This feature is crucial for various decentralized applications, as it enables seamless and secure financial transactions on the blockchain.
