What is circle-test?

HashCrew is a Web3 wallet built for the Arc Testnet, a blockchain test network from Circle, the company behind the USDC stablecoin. The project is meant to show how people could send, swap, and manage stablecoin payments in a simple, game-like app rather than through a typical crypto interface with seed phrases and wallet addresses. Instead of creating a wallet the traditional crypto way, users sign in with their Google account. Circle's wallet software then creates a blockchain wallet tied to that account behind the scenes, so there is no seed phrase to write down or lose. From there, users can send USDC to other people, swap between USDC and EURC, a euro backed stablecoin, and build up a transaction history over time. The app also wraps these actions in a set of lighter, game-like features. There is a staking section called Staking Garden, where users plant seeds and watch them grow as a way of visualizing staked funds. There are achievement badges for sending, staking, and swapping, an analytics view with balance history charts, a small AI assistant that can answer questions about the user's balance and help with transactions, and a learning section with content pulled from the Arc House community. The project is built with Next.js 16, TypeScript, and React on the frontend, and connects to Arc Testnet through Circle's wallet SDK for the blockchain and wallet parts, plus Google OAuth for login. It is deployed on Vercel, and a live demo link is included in the README. To run it locally, you clone the repository, install dependencies with npm, copy an example environment file, and fill in a Circle API key, a Google client ID, and a Circle app ID before starting the development server. Since this depends on the Arc Testnet and Circle's software development kit, it is a demo project rather than something ready to hold real money, and it reads as a personal or hackathon style project from a single developer rather than a maintained open source library.
