This is a web application for Giwa Sepolia, a test network for a layer 2 blockchain built on top of Ethereum. Layer 2 networks are separate chains that settle back to Ethereum to move funds faster and more cheaply. The app combines two related features in one Next.js site: a faucet that gives out small free amounts of test cryptocurrency, and a bridge that lets people move funds between the main test network, called Sepolia, and the Giwa Sepolia layer 2 network. On the homepage, anyone can donate test funds to the faucet address, and users can request a small drip of Giwa Sepolia test ETH once every 24 hours. A scheduled job runs once a day and automatically moves any surplus funds from the main network up to the layer 2 network to keep the faucet supplied, using the standard deposit process for this type of blockchain bridge. On the bridge page, users connect their own crypto wallet and move ETH or other tokens between the two networks themselves. Moving funds down to the layer 2 network is a single transaction for ETH. Moving funds back up to the main network is a three step process: starting the withdrawal, then a required waiting period of about two hours to prove it happened, then a further waiting period of about seven days before the funds can finally be claimed. The app tracks a user's pending withdrawals directly from public blockchain records tied to their wallet address, rather than storing that information locally, so it works the same way across different devices. The project is built with Next.js, Tailwind CSS, and several standard Ethereum development libraries, and is meant to be deployed on Vercel. Setting it up requires creating a dedicated wallet to hold and send the faucet's funds, and configuring how that wallet's private key is stored and signed, with options ranging from a simple environment variable for testing up to cloud key management services for production use. No license is mentioned in the README, so its terms of reuse are unclear.
