A collection of composable functions for implementing web3-onboard in to a Solid project;
NPM
npm i @web3-onboard/solid @web3-onboard/injected-wallets ethers
PNPM
pnpm i @web3-onboard/solid @web3-onboard/injected-wallets ethers
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
}
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
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
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:
import { useOnboard } from '@web3-onboard/solid'
// Use the composable
const onboard = useOnboard()
// Or destructure it
const {
wallets,
connectedWallet,
connectedChain,
connectWallet,
disconnectConnectedWallet
} = useOnboard()
// do stuff
Function to open the onboard modal and connect to a wallet provider. For reference check out the connecting a wallet for @web3-onboard/core
function SampleConnect() {
const { connectWallet } = useOnboard()
return <button onClick={() => connectWallet()}> connect wallet</button>
}
Property that contains the current chain to which connectedChain
is connected
function SampleConnect() {
const { connectedChain } = useOnboard()
return <span>Connected Chain: { connectedChain() }</span>
Property that contains the latest connected wallet
function SampleConnect() {
const { connectedWallet } = useOnboard()
return <span>Connected Wallet: {connectedWallet()?.label}</span>
}
Function to disconnect the connectedWallet
import { useOnboard } from '@web3-onboard/solid'
function SampleConnect() {
const { disconnectConnectedWallet } = useOnboard()
return (
<button onClick={() => disconnectConnectedWallet()}>
{' '}
disconnect wallet
</button>
)
}
Function that returns the current chain a wallet is connected to
import { useOnboard } from '@web3-onboard/solid'
function SampleConnect() {
const { getChain } = useOnboard()
return <span>MetaMask is connected to: {getChain('MetaMask')}</span>
}
Function to set the chain of a wallet
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>
)
}
Readonly boolean ref that tracks the status of setting the chain
import { useOnboard } from '@web3-onboard/solid'
function SampleConnect() {
const { settingChain } = useOnboard()
return { settingChain }
}
Readonly ref that contains every wallet that has been connected
import { useOnboard } from '@web3-onboard/solid'
function SampleConnect() {
const { wallets } = useOnboard()
return(
<ul>
<For each={wallets()}>{wallet=>{
return <li>
{wallet.label}
</li>
}}
</For>
</ul>
)
}
}
Readonly ref that contains the last time that the user connected a wallet in milliseconds
import { useOnboard } from '@web3-onboard/solid'
function SampleConnect() {
const { lastConnectedTimestamp } = useOnboard()
return (
<span>Your last connection timestamp was: {lastConnectedTimestamp}</span>
)
}
