Modules

Solid.js

A collection of composable functions for implementing web3-onboard in to a Solid project;

Quickstart with Injected Wallets and Ethers Provider

Install

Quickstart

        import { init } from '@web3-onboard/solid'
import injectedModule from '@web3-onboard/injected-wallets'

const injected = injectedModule()

// Only one RPC endpoint required per chain
const rpcAPIKey = '<INFURA_KEY>' || '<ALCHEMY_KEY>'
const rpcUrl =
  `https://eth-mainnet.g.alchemy.com/v2/${rpcAPIKey}` ||
  `https://mainnet.infura.io/v3/${rpcAPIKey}`

const web3Onboard = init({
  wallets: [injected],
  chains: [
    {
      id: '0x1',
      token: 'ETH',
      label: 'Ethereum Mainnet',
      rpcUrl
    },
    {
      id: '0x2105',
      token: 'ETH',
      label: 'Base',
      rpcUrl: 'https://mainnet.base.org'
    }
  ]
})

const { wallets, connectWallet, disconnectConnectedWallet, connectedWallet } =
  useOnboard()

if (connectedWallet) {
  // if using ethers v6 this is:
  // ethersProvider = new ethers.BrowserProvider(wallet.provider, 'any')
  const ethersProvider = new ethers.providers.Web3Provider(
    connectedWallet.provider,
    'any'
  )
  // ..... do stuff with the provider
}

Functions

init

The init function initializes web3-onboard and makes it available to the useOnboard() composable. For references check out the initialization docs for @web3-onboard/core

Example usage

        import { init } from '@web3-onboard/solid'
import injectedModule from '@web3-onboard/injected-wallets'

const injected = injectedModule()
const infuraKey = '<INFURA_KEY>'
const rpcUrl = `https://mainnet.infura.io/v3/${infuraKey}`

const web3Onboard = init({
  wallets: [injected],
  chains: [
    {
      id: '0x1',
      token: 'ETH',
      label: 'Ethereum Mainnet',
      rpcUrl
    }
  ]
})

useOnboard

useOnboard must be used after the init function has been called - it will return an object that can be destructured to obtain the following reactive variables and functions:

Example usage

        import { useOnboard } from '@web3-onboard/solid'
// Use the composable
const onboard = useOnboard()
// Or destructure it
const {
  wallets,
  connectedWallet,
  connectedChain,
  connectWallet,
  disconnectConnectedWallet
} = useOnboard()
// do stuff

connectWallet

Function to open the onboard modal and connect to a wallet provider. For reference check out the connecting a wallet for @web3-onboard/core

Example usage

        function SampleConnect() {
  const { connectWallet } = useOnboard()

  return <button onClick={() => connectWallet()}> connect wallet</button>
}

connectedChain

Property that contains the current chain to which connectedChain is connected

Example usage

        function SampleConnect() {
    const { connectedChain } = useOnboard()

  return <span>Connected Chain: { connectedChain() }</span>

connectedWallet

Property that contains the latest connected wallet

Example usage

        function SampleConnect() {
  const { connectedWallet } = useOnboard()
  return <span>Connected Wallet: {connectedWallet()?.label}</span>
}

disconnectConnectedWallet

Function to disconnect the connectedWallet

Example usage

        import { useOnboard } from '@web3-onboard/solid'
function SampleConnect() {
  const { disconnectConnectedWallet } = useOnboard()
  return (
    <button onClick={() => disconnectConnectedWallet()}>
      {' '}
      disconnect wallet
    </button>
  )
}

getChain

Function that returns the current chain a wallet is connected to

Example usage

        import { useOnboard } from '@web3-onboard/solid'
function SampleConnect() {
  const { getChain } = useOnboard()
  return <span>MetaMask is connected to: {getChain('MetaMask')}</span>
}

setChain

Function to set the chain of a wallet

Example usage

        import { useOnboard } from '@web3-onboard/solid'
function SampleConnect() {
  const { setChain } = useOnboard()
  const set = () => setChain({ wallet: 'MetaMask', chainId: '0x1' })
  return (
    <button type="button" onClick={set}>
      Set MetaMask chain to mainnet
    </button>
  )
}

settingChain

Readonly boolean ref that tracks the status of setting the chain

Example usage

        import { useOnboard } from '@web3-onboard/solid'
function SampleConnect() {
  const { settingChain } = useOnboard()
  return { settingChain }
}

wallets

Readonly ref that contains every wallet that has been connected

Example usage

        import { useOnboard } from '@web3-onboard/solid'
function SampleConnect() {
    const { wallets } = useOnboard()
   return(
    <ul>
    <For each={wallets()}>{wallet=>{
      return <li>
        {wallet.label}
      </li>
      }}
    </For>
    </ul>
   )
  }
}

lastConnectedTimestamp

Readonly ref that contains the last time that the user connected a wallet in milliseconds

Example usage

        import { useOnboard } from '@web3-onboard/solid'
function SampleConnect() {
  const { lastConnectedTimestamp } = useOnboard()
  return (
    <span>Your last connection timestamp was: {lastConnectedTimestamp}</span>
  )
}
