Ethereum 🤝 React

Framework for rapid Dapp development.
Simple. Robust. Extendable. Testable.

About

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

Example

import{Mainnet}from'@usedapp/core/modal/chain/ethereum'import{useEthers,useEtherBalance}from'@usedapp/core'constconfig={readOnlyChainId: Mainnet.chainId,readOnlyUrls: {[Mainnet.chainId]: 'https://mainnet.infura.io/v3/62687d1a985d4508b2b7a24827551934',},}ReactDOM.render(<DAppProviderconfig={config}><App/></DAppProvider>,document.getElementById('root'))constSTAKING_CONTRACT='0x00000000219ab540356cBB839Cbe05303d7705Fa'exportfunctionApp(){const{ activateBrowserWallet, deactivate, account }=useEthers()constuserBalance=useEtherBalance(account)conststakingBalance=useEtherBalance(STAKING_CONTRACT)return(<div>{!account&&<buttononClick={activateBrowserWallet}> Connect </button>}{account&&<buttononClick={deactivate}> Disconnect </button>}{stakingBalance&&<p>ETH2 staking balance: {formatEther(stakingBalance)} ETH </p>}{account&&<p>Account: {account}</p>}{userBalance&&<p>Ether balance: {formatEther(userBalance)} ETH </p>}</div>)}

Ethereum 🤝 React
Framework for rapid Dapp development.

Simple. Robust. Extendable. Testable.
About
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
Example
import{Mainnet}from'@usedapp/core/modal/chain/ethereum'import{useEthers,useEtherBalance}from'@usedapp/core'constconfig={readOnlyChainId: Mainnet.chainId,readOnlyUrls: {[Mainnet.chainId]: 'https://mainnet.infura.io/v3/62687d1a985d4508b2b7a24827551934',},}ReactDOM.render(<DAppProviderconfig={config}><App/></DAppProvider>,document.getElementById('root'))constSTAKING_CONTRACT='0x00000000219ab540356cBB839Cbe05303d7705Fa'exportfunctionApp(){const{ activateBrowserWallet, deactivate, account }=useEthers()constuserBalance=useEtherBalance(account)conststakingBalance=useEtherBalance(STAKING_CONTRACT)return(<div>{!account&&<buttononClick={activateBrowserWallet}> Connect </button>}{account&&<buttononClick={deactivate}> Disconnect </button>}{stakingBalance&&<p>ETH2 staking balance: {formatEther(stakingBalance)} ETH </p>}{account&&<p>Account: {account}</p>}{userBalance&&<p>Ether balance: {formatEther(userBalance)} ETH </p>}</div>)}
