Developer builds index basket app on Robinhood Chain

A developer created a simple index basket app on Robinhood Chain, a custom Arbitrum chain, to explore the full developer path from contract deployment to frontend. The app lets users deposit Stock Tokens and receive ERC-20 basket shares priced via live feeds. The project uses standard Ethereum tools like Solidity, Foundry, viem, and wagmi, showing that custom chains can still leverage familiar developer workflows.
