Choodle is a simple mobile-first doodling app that publishes to the blockchain. By enabling creative expression and ownership, Choodle seeks to bring the advantages of web3 technologies to typical users without friction.
- Optimized for drawing on mobile touchscreens
- "Undo" functionality to remove last line stroke from canvas
- Text-based prompt for drawing, updatable via CMS (Sanity)
- Ability to save a black-and-white, aliased image with a 3:4 aspect ratio
- Image saved with unique browser ID
- Native sharing via "share" button allows user to save image, share via messaging application of choice, etc.
Choodle consists of three main parts: the progressive web app client, a Sanity Studio instance, and the smart contract for holding a collection of Choodles as on-chain ERC721 tokens.
frontend: built with SvelteKit.choodle-cms: a Sanity Studio application for viewing stored choodles, and static content for the interface.contracts: the smart contract that holds the collection of choodles.
To use the web client, run pnpm dev in the frontend/ directory, and connect to it
on [http://localhost:5173/]
To use Sanity Studio, run pnpm dev in the choodle-cms/ directory, and connect to it on [http://localhost:3333/]
We use Hardhat for building and testing smart contract code, and OpenZeppelin
Use hardhat tasks to deploy smart contracts to local / testnet / mainnet as needed. We host the PWA and sanity client on Vercel, which has an easy configuration for automatically deploying Sveltekit based on repo updates.
