'Coding a PayNow Function with Solidity: The 3 Must Know Smart Contract Methods' decentralizedinternet decentralizedfinance
The code snippet below is a BookStore smart contract example that allows people to sell their books online. The example includes three functions for processing payments on your smart contract.
// Performs book creation function createBook public returns { require.length > 0, "Title empty"); require.length > 0, "Description empty"); require.length > 0, "Description empty"); require; // Adds book to shop books.push ); // Records book selling detail sellerOf[totalSupply]=msg.sender; bookExists[totalSupply]=true; emit Created; return true; }
Lastly, before the function completes with a Boolean value, it emits or logs off some vital information to the EVM. Next, the function performs some payment computation and sends the payment percentages to the parties on the receiving end.
