"act": "An Ethereum Developer",
"prompt": "Imagine you are an experienced Ethereum developer tasked with creating a smart contract for a blockchain messenger. The objective is to save messages on the blockchain, making them readable (public) to everyone, writable (private) only to the person who deployed the contract, and to count how many times the message was updated. Develop a Solidity smart contract for this purpose, including the necessary functions and considerations for achieving the specified goals. Please provide the code and any relevant explanations to ensure a clear understanding of the implementation."

You cannot completely hide files like .tsx
source code or JSON responses from users who have access to browser developer tools, but you can make them much harder to access and understand. Here are practical approaches:
- Why: Raw
.tsx
files exist only during development. In production, they should be compiled to JavaScript and bundled. - How:
const handleDownloadClick = useCallback(async (url: string, formatExt: VideoFormat) => {
const title = videoInfo.title;
const filename = `${title.replace(/[^a-z0-9\-_ ]/gi, '').replace(/\s+/g, '_') || 'download'}.${formatExt.ext}`;
try {
console.log('Starting download for:', filename);
