ethereum-boilerplate

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

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.

πŸ— Ethereum Components
πŸ›  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.

πŸ“¨

: Displays an Ethereum address with Blockie avatar.
Options:
copyable (optional): display icon for copying.
avatar (optional): display blockie avatar.
size (optional): text size.




πŸ“« : Input for eth address. Displays Blockie avatar for the entered wallet. Helps to validate addresses. After entering 42 characters (wallet length) freezes inout and calls setValidatedAddress
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();


β›“ : Active network switch. Supports Ethereum, Polygon, BSC and Avalacnhe blockchains. Works only with networks that have already been added to Injected Wallet. You can find a guide on how to programmatically add a new network here. Easily customizable, you can add other networks
Options:
props (optional): networks to display. Added by default: polygon, eth, bsc and avalanche

πŸ’΅ : displays the price of the token specified in the settings. Uses Moralis Web3API (does not require an active web3 provider).
Options:
address (required): Token contract address
chain (optional): The network to which the token is deployed. Default: ETH
image (optional): local path or link to token logo
size (optional): logo size

πŸ’° : displays the ERC20 balance of an address. Uses Moralis Web3API (does not require an active web3 provider).
Options:
chain (optional): network for displaying balances on. Will use your wallet network if you do not specify chain yourself

πŸ’Έ : displays the ERC20 transfers of an address. Uses Moralis Web3API (does not require an active web3 provider).
Options:
chain (optional): network for displaying transfers on. Will use your wallet network if you do not specify chain yourself

πŸ’± : interface for Moralis 1Inch Plugin. This plugin integrates the DeFi / DEX aggregator 1Inch to any project that uses Moralis.
Options:
chain (optional): network. Available: Ethereum (β€œeth”), Binance Smart Chain (β€œbsc”), Polygon (β€œpolygon”)

πŸ’Ό : example interface for interacting with your wallet. Uses components from the boilerplate: ,

, , . Has the functionality to send tokens




🧰 Ethereum Hooks
useAPIContract()
πŸ“‹ Runs a given function of a contract abi and returns readonly data. Uses Moralis Web3API (does not require an active web3 provider).
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 Eth.
functionName (required): The function name
address (required): A smart contract address
abi (required): contract or function ABI(should be provided as an array)
Example:
const ShowUniswapTotalSupplyLP = () => {
const { runContractFunction, contractResponse, error, isLoading } = useAPIContract({
abi: usdcEthPoolAbi,
address: usdcEthPoolAddress,
functionName: “totalSupply”,
});

return (

{error && }

{data &&

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

}

)
}
useWeb3Contract()
πŸ“‹ Runs on-chain functions. Requires active Web3 Provider.
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 Eth.
functionName (required): The function name
contractAddress (required): A smart contract address
abi (required): contract or function ABI(should be provided as an array)
params (optional): Parameters needed for your specific function
Example:
const ShowUniswapObserveValues = () => {
const { runContractFunction, contractResponse, error, isRunning, isLoading } = useWeb3Contract({
abi: usdcEthPoolAbi,
contractAddress: usdcEthPoolAddress,
functionName: “observe”,
params: {
secondsAgos: [0, 10],
},
});

return (

{error && }

{data &&

      {JSON.stringify(contractResponse),
