Framework for rapid Dapp development.
Simple. Robust. Extendable. Testable.
Introduces great features:
- 🏗️ React hooks - Uses React hooks as your primary building ingredient
- 🚅 Auto refresh - Refreshes on a new block, wallet change or network change
- 🛒 Multicall - Combines multiple blockchain calls into a single multicall
Combines the best practices:
- 🔧 Modern stack - Employs ethers.js, multicall & waffle
- 📚 Extendability - Extends easily with custom hooks
- 💡 Testability - Simple integration tests for UI and blockchain
