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.
If this boilerplate helps you build Ethereum dapps faster - please star this project, every star makes us very happy!
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.
📄 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🛠 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,sizeand etc.

}⛓ Hook for fast network switching or getting info about current network. To change the current network, set the target chainId to switchNetwork function. If the user does not have the target network in the wallet, it will automatically ask permission to add it to the wallet.
Example:
import { useChain } from "react-moralis";
function Chains() {
const { switchNetwork, chainId, chain, account } = useChain();
return (
<>
<button onClick={() => switchNetwork("0x1")}>Switch to Ethereum</button>

}💰 Gets the price nominated in the native token and usd for a given token contract address
Options:
chain(optional): The blockchain to get data from. Valid values are listed on the intro page in the Transactions and Balances section. Default value: current chain (if the chain is not supported it will use the Eth chain).address(optional): A user address (i.e. 0x1a2b3x...). If specified, the user attached to the query is ignored and the address will be used instead.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).
