2. Error Handling Techniques

2.1. Using try-catch Blocks

Using try-catch blocks allows for structured error handling within your application. This is particularly useful for handling synchronous code.

code
try {
    // Code that may throw an error
} catch (error) {
    // Handle the error
}

2.2. Leveraging Promises and Async/Await

For handling asynchronous code, leverage Promises and Async/Await to manage errors in a more organized manner.

code
async function fetchAccount() {
    try {
        const accounts = await ethereum.request({ method: 'eth_requestAccounts' });
        return accounts[0];
    } catch (error) {
        console.error(error);
        throw new Error('Failed to fetch account');
    }
}
