This is the official repo for HelloBase, a starting place for any developer who is interested in building onchain.
The app is composed of two pieces:
- Next.js client
- Smart Contracts on Base Sepolia
This repo contains the code for the Next.js client and uses a combination of Wagmi.sh and Coinbase Smart Wallets to provide a seemless experience for anyone to start building onchain. Below is a flow chart for the user experience and what happens behind the scenes.
