what is arc-dex-ui fr?

ArcDEX describes itself as the first decentralized exchange interface built for something called the Arc Testnet, a test version of a blockchain network used for trying out new features before they go live for real money. According to the project's short description, it lets people swap between two types of digital tokens, USDC and EURC, which are digital versions of the US dollar and the euro pegged one to one in value, with sub second finality, meaning trades are confirmed and settled in under a second. Beyond that short description, the README included in this repository does not actually explain any of that. Instead, it is the standard, unedited starter text that comes automatically when someone creates a new Next.js project using the create-next-app tool. It only covers generic instructions: how to start a local development server with commands like npm run dev, where to find the main page file to edit, and links to Next.js's own documentation and a suggested way to deploy the finished site to Vercel, the company behind Next.js. Because the README has not been filled in with real project details, there is no information here about how the swap feature actually works, what smart contracts or blockchain libraries the interface talks to, how wallets connect, or what sub second finality specifically relies on. Anyone wanting to understand ArcDEX's actual behavior would need to look through the application's source code directly rather than this documentation page, since the page currently only reflects the default project template rather than the finished product it is meant to describe.
