what is amphi fr?

Amphi is a simulated economy built on a test blockchain network called GIWA Sepolia, meant for experimenting with how money might move between risky crypto assets and safer commodity backed assets like gold, silver, and platinum. It is not connected to real money. Everything runs on test tokens that stand in for things like Bitcoin, Ethereum, and stablecoins, priced using live market data pulled from real world sources so the simulation feels realistic. The project gives users several ways to interact with this pretend economy through a website. A faucet lets anyone claim a starting set of seven tokens for free, one time per wallet address. A premium faucet lets you buy simulated gold, silver, or platinum using test ETH at prices tracking the real market. From there you can swap between different tokens, add or remove funds from liquidity pools that make those swaps possible, or lock up commodity tokens in a vault for a set number of days to earn rewards over time. Larger decisions, like protocol changes, are controlled by a multi signature wallet with a 24 hour delay before changes take effect. Under the hood, the smart contracts are written in Solidity using the Foundry development toolkit, a background script keeps prices updated using outside price data sources, and the website itself is built with React and related web tools. All of the contracts are published and viewable on a blockchain explorer called Blockscout, and the author notes the contracts were reviewed with help from AI tools during development, but the project has not gone through a formal audit by a professional blockchain security firm. The README describes plans to eventually let anyone create and list their own tokens in the sandbox as a second phase. The project is released under the MIT license.
