Ethereum boilerplate - React components and hooks for fast building dApps

ethereum-boilerplate

React components and hooks for fast building dApps without running own backend

🚀DEMO: https://ethereum-boilerplate.github.io/ethereum-boilerplate

This boilerplate is built on react-moralis and Moralis. Also has its own context provider for quick access to chainId or ethAddress

There are many components in this boilerplate that do not require an active web3 provider, they use Moralis Web3 API. Moralis supports the most popular blockchains and their test networks. You can find a list of all available networks in Moralis Supported Chains

Please check the official documentation of Moralis for all the functionalities of Moralis.

🤝 Need help?

If you need help with setting up the boilerplate or have other questions - don't hesitate to write in our community forum and we will check asap. Forum link. The best thing about this boilerplate is the super active community ready to help at any time! We help each other.

🚀 Quick Start

📄 Clone or fork ethereum-boilerplate:

git clone https://github.com/ethereum-boilerplate/ethereum-boilerplate.git

💿 Install all dependencies:

cd ethereum-boilerplate
yarn install

✏ Rename .env.example to .env in the main folder and provide your appId and serverUrl from Moralis (How to start Moralis Server) Example:

REACT_APP_MORALIS_APPLICATION_ID = xxxxxxxxxxxx
REACT_APP_MORALIS_SERVER_URL = https://xxxxxx.grandmoralis.com:2053/server

🚴‍♂️ Run your App:

yarn start

🏗 Ethereum Components

🛠 The ready for use react-components are located in src/components. They are designed to be used anywhere in your dApp.

⚡ Note that many components may get params like chain, address, size and etc.

Account

address

📨

: Displays an Ethereum address with Blockie avatar.

Options:

  • copyable (optional): display icon for copying.
  • avatar (optional): display blockie avatar.
  • size (optional): text size.

input

📫 : Input for eth address. Displays Blockie avatar for the entered wallet. Helps to validate addresses. After entering 42 characters (0x… wallet length) or valid crypto domain freezes input and calls setValidatedAddress. Supported domains: [".eth", ".crypto", ".coin", ".wallet", ".bitcoin", ".x", ".888", ".nft", ".dao", ".blockchain"]

Options:

  • autoFocus (optional): focuses object after rendering the component.
  • placeholder (optional): text to display before entering address.
  • onChange (required): your setState hook.
const [address, setAddress] = useState();

network

import { useChain } from "react-moralis";

function Chains() {

  return (
    <>

useTokenPrice()

💰 Gets the price nominated in the native token and usd for a given token contract address

Options:

  • exchange (optional): The factory name or address of the token exchange. Possible exchanges, for different chains are: ETH mainnet: uniswap-v3, sushiswap, uniswap-v2, BSC mainnet: pancakeswap-v2, pancakeswap-v1. Polygon mainnet: quickswap. If no exchange is specified, all exchanges are checked (in the order as listed above) until a valid pool has been found. Note that this request can take more time. So specifying the exchange will result in faster responses most of the time.
  • to_block (optional): Returns the price for a given blocknumber (historical price-data).

Example

import { useTokenPrice } from "react-moralis";

const TokenPrice = () => {
  const { fetchTokenPrice, data: formattedData, error, isLoading, isFetching } = useTokenPrice({ address: "0x1f9840...1f984", chain: "eth" });

{JSON.stringify(data, null, 2)}

    

  );
}
