## Overview

This is a centralized wallet-and-transfer web app: users look up an address balance, then submit a transfer; the server updates its in-memory balances. The sampled source implements neither ECDSA signing nor signature verification. The README describes those as project goals and phased work, so they are not shown as runtime components. The graph follows the sampled client components and server routes; unsampled files may contain additional behavior.

Main entry points: [`client/src/server.js`](https://github.com/azeezabidoye/ecdsa-node-au/blob/main/client/src/server.js) (Axios client), [`server/index.js`](https://github.com/azeezabidoye/ecdsa-node-au/blob/main/server/index.js) (Express API), [`client/src/App.jsx`](https://github.com/azeezabidoye/ecdsa-node-au/blob/main/client/src/App.jsx) (App shell), [`client/src/Wallet.jsx`](https://github.com/azeezabidoye/ecdsa-node-au/blob/main/client/src/Wallet.jsx) (Wallet view)
