This is the core package that contains all of the UI and logic to be able to seamlessly connect user's wallets to your app and track the state of those wallets. Onboard no longer contains any wallet specific code, so wallets need to be passed in upon initialization.
Tip: Release 2.24.0 moves the default position of the account center from topRight to bottomRight. To reset your application to topRight, include the following when initializing onboard:
accountCenter: {
desktop: {
enabled: true,
position: 'topRight'
},
mobile: {
enabled: true,
position: 'topRight'
}
}

Install the core module:
npm i @freedx-connect/core
If you would like to support all wallets, then you can install all of the wallet modules:
npm i @web3-onboard/coinbase @web3-onboard/fortmatic @web3-onboard/gnosis @web3-onboard/infinity-wallet @web3-onboard/trust
@web3-onboard/injected-wallets @web3-onboard/keepkey @web3-onboard/keystone

theme
A string or an object that defines the color theme web3-onboard will render the components.
Define a custom or predefined theme for Web3Onboard using either:
- Native themes available: 'default', 'dark', 'light', 'system'
-
ThemingMap
object to create a totally custom theme - see below for the typing
Note: system
will default to the theme set by the users system.
type Theme = ThemingMap | BuiltInThemes | 'system'
type BuiltInThemes = 'default' | 'dark' | 'light'
type ThemingMap = {
'--w3o-background-color'?: string

'--w3o-border-color'?: string
'--w3o-action-color'?: string
'--w3o-border-radius'?: string
}
disableFontDownload
If set to true
the default Inter
font will not be imported and instead the web based sans-serif
font will be used if a font is not defined through the Theme
or exposed css variable.
To define the font use --w3o-font-family
prop within the Theme
initialization object or set as a css variable.
type disableFontDownload = boolean // defaults to false
i18n
An object that defines the display text for different locales. Can also be used to override the default text. To override the default text, pass in a object for the en
locale.
type Locale = string // eg 'en', 'es'
type i18nOptions = Record<Locale, i18n>
To see a list of all of the text values that can be internationalized or replaced, check out the default en file. Onboard is using the ICU syntax for formatting under the hood.
For example, to update the connect interface language for Metamask, while giving a different message for other wallets, you can include the following:
i18n: {
en: {
connect: {
connectingWallet: {
paragraph: '{wallet, select, MetaMask {{wallet} can only present one account, so connect just the one account you want.} other {Please connect to all of your accounts in {wallet}.}}'
}
}
}
}
Default Message- with no i18n override:
containerElements
An object mapping for W3O components with the key being the DOM element to mount the specified component to.
This defines the DOM container element for svelte to attach the component.
NOTE: containerElement must be a DOM element with a styleSheet property attached and the element must be available on the DOM at the time of component mounting. For an example please see containerElement usage here
type ContainerElements = {
// When attaching the Connect Modal to a container el be aware that the modal was styled to be
// mounted through the app to the html body and will respond to screen width rather than container width
// This is specifically apparent on mobile so please test thoroughly
// Also consider that other DOM elements(specifically Notifications and Account Center) will also
// append to this DOM el if enabled and their own containerEl are not defined
connectModal?: string
// when using the accountCenter with a container el the accountCenter position properties are ignored
accountCenter?: string
}
accountCenter
An object that defines whether the account center UI (default and minimal) is enabled and it's position on the screen. Currently the account center is enabled for both desktop and mobile devices.
type AccountCenter = {
enabled: boolean
position?: AccountCenterPosition // default: 'bottomRight'
expanded?: boolean // default: true

notify
Notify is a feature that provides transaction notifications for all connected wallets on the current blockchain. This document will provide you with an overview of Notify and guide you through the process of integrating it into your decentralized application (DApp).
To enable transaction notifications and updates simply add your Blocknative apiKey
(sign up for free) to the web3-onboard configurations as the value to the apiKey
prop and thats it!
Transaction notifications will be shown for all transactions occurring on supported chains for all of the users connected wallets.
When switching chains, the previous chain listeners remain active for 60 seconds to allow the capture and report of any remaining transactions that may be in flight.
Notifications are by default positioned in the same location as the Account Center (if enabled) or can be positioned separately using the position
property.
Property | Type | Description |
---|---|---|
enabled |
boolean | Indicates whether transaction notifications will be displayed |
transactionHandler |
function | Optional callback for customizations of notifications |
position |
CommonPositions | Position of the notification on the screen |
Property | Type | Description |
---|---|---|
desktop |
Notify | Configuration for desktop notifications. |
mobile |
Notify | Configuration for mobile notifications. |
Both desktop
and mobile
configurations are of type Notify
.
The transactionHandler
is a callback that receives an object of type EthereumTransactionData
. Based on the data received, the handler can return a custom Notification
object or a boolean value (false to disable the notification for the current event or undefined for a default notification).
Property | Type | Description |
---|---|---|
message |
string | Customizes the message shown |
eventCode |
string | Allows handling codes in a custom way |
type |
string | Represents the icon type displayed |
autoDismiss |
number | Time (in ms) after which the notification will be dismissed |
link |
string | Adds a link to the transaction hash |
onClick |
function | onClick handler for the notification element |
Notify automatically will match the theme
defined in the web3-onboard config. It can also be styled using the exposed css variables provided below. These variables allow for maximum customization with base styling variables setting the global theme (e.g., --onboard-grey-600
) and more precise component-level styling variables available (--notify-onboard-grey-600
). The latter takes precedence if defined.
If notifications are enabled, they can be fielded and handled through the onboard app state as seen in the example below - although this is not required for notifications to display:
const wallets = onboard.state.select('notifications')
const { unsubscribe } = wallets.subscribe(update =>
console.log('transaction notifications: ', update)
)
// unsubscribe when updates are no longer needed
unsubscribe()
The Notifications messages can also be used to send fully customized Dapp toast messages and updated. Check out the customNotifications API docs for examples and code snippets
const wallets = onboard.state.select('notifications')
const { unsubscribe } = wallets.subscribe(update =>
console.log('transaction notifications: ', update)
)
// unsubscribe when updates are no longer needed
unsubscribe()
type NotifyOptions = {
desktop: Notify

To initiate a user to select and connect a wallet you can call the connectWallet
function on an initialized Onboard instance. It will return a Promise
that will resolve when the user either successfully connects a wallet, or when they dismiss the UI. The resolved value from the promise will be the latest state of the wallets
array. The order of the wallets array is last to first, so the most recently selected wallet will be the first item in the array and can be thought of as the "primary wallet". If no wallet was selected, then the wallets
array will have the same state as it had before calling connectWallet
.
async function connectWallet() {
const wallets = await onboard.connectWallet()
console.log(wallets)
}
connectWallet()
A common UX pattern is to remember the last wallet that a user has previously connected by storing it in localStorage and then automatically selecting them for the user next time they visit your app.
You can enable this in your app by using the autoConnectLastWallet
parameter when initializing and Onboard will take care of it:
const onboard = Onboard({
// ... other options
connect: {
autoConnectLastWallet: true
}
})
A wallet can be disconnected, which will cleanup any background operations the wallet may be doing and will also remove it from the Onboard wallets
array:
// disconnect the first wallet in the wallets array
const [primaryWallet] = onboard.state.get().wallets
await onboard.disconnectWallet({ label: primaryWallet.label })
The disconnectWallet
method takes the wallet.label
value and returns a Promise
that resolves to the current state of the wallets
array.
Onboard currently keeps track of the following state:
-
wallets
: The wallets connected to Onboard -
chains
: The chains that Onboard has been initialized with -
accountCenter
: The current state of the account center UI -
walletModules
: The wallet modules that are currently set and will be rendered in the wallet selection modal

The current state of Onboard can be accessed at any time using the state.get()
method:
const currentState = onboard.state.get()
State can also be subscribed to using the state.select()
method. The select
method will return an RXJS Observable. Understanding of RXJS observables is not necessary to subscribe to state updates, but allows for composable functionality if wanted. The key point to understand is that if you subscribe for updates, remember to unsubscribe when you are finished to prevent memory leaks.
To subscribe to all state updates, call the select
method with no arguments:
const state = onboard.state.select()
const { unsubscribe } = state.subscribe(update =>
console.log('state update: ', update)
)
// remember to unsubscribe when updates are no longer needed
// unsubscribe()
Specific top level slices of state can be subscribed to. For example you may want to just subscribe to receive updates to the wallets
array only:
const wallets = onboard.state.select('wallets')
const { unsubscribe } = wallets.subscribe(update =>
console.log('wallets update: ', update)
)
// unsubscribe when updates are no longer needed
unsubscribe()
A limited subset of internal actions are exposed to update the Onboard state.
setWalletModules
For updating the wallets that are displayed in the wallet selection modal. This can be used if the wallets you want to support is conditional on another user action within your app. The setWalletModules
action is called with an updated array of wallets (the same wallets that are passed in on initialization)
import Onboard from '@freedx-connect/core'
import injectedModule from '@web3-onboard/injected-wallets'
import ledgerModule from '@web3-onboard/ledger'
import trezorModule from '@web3-onboard/trezor'
const injected = injectedModule()
const ledger = ledgerModule()
const trezor = trezorModule({
email: '<EMAIL_CONTACT>',
appUrl: '<APP_URL>'
})
// initialize with injected and hardware wallets
const onboard = Onboard({

})
// then after a user action, you may decide to only display hardware wallets on the next call to onboard.connectWallet
onboard.state.actions.setWalletModules([ledger, trezor])
updateTheme
An exposed method for updating the theme of web3-onboard. The function accepts Theme
types (see below)
Available native themes include:
'default' | a mix of light and dark elements found throughout the web3-onboard components |
'dark' | modern look - easy on the eyes in low-light settings |
'light' | bright and clean look - easier to read in bright environments |
'system' | automatically switch between 'dark' & 'light' based on the user's system settings |
The function also accepts a custom built ThemingMap
object that contains all or some of the theming variables
Example:
import Onboard from '@freedx-connect/core'
import injectedModule from '@web3-onboard/injected-wallets'
const injected = injectedModule()
const onboard = Onboard({
theme: 'dark',
wallets: [injected],
chains: [
{
id: '0x1',
token: 'ETH',
label: 'Ethereum Mainnet',
rpcUrl: `https://mainnet.infura.io/v3/${INFURA_KEY}`
}
]
})
// after initialization you may want to change the theme based on a theme switch within the dapp
onboard.state.actions.updateTheme('light')
// or
const customTheme: ThemingMap = {
'--w3o-background-color': '#f0f0f0',
'--w3o-foreground-color': '#333',
'--w3o-text-color': '#fff',
'--w3o-border-color': '#ccc',
'--w3o-action-color': '#007bff'
}
onboard.state.actions.updateTheme(customTheme)
type Theme = ThemingMap | BuiltInThemes | 'system'
type BuiltInThemes = 'default' | 'dark' | 'light'
type ThemingMap = {
'--w3o-background-color'?: string
'--w3o-foreground-color'?: string
'--w3o-text-color'?: string
'--w3o-border-color'?: string
'--w3o-action-color'?: string
'--w3o-border-radius'?: string
}
updateBalances
You may decide to get updated balances for connected wallets after a user action by calling the updatedBalances
function, which expects a conditional array of addresses:
onboard.state.actions.updateBalances() // update all balances for all connected addresses
onboard.state.actions.updateBalances(['0xfdadfadsadsadsadasdsa']) // update balance for one address
onboard.state.actions.updateBalances([
'0xfdadfadsadsadsadasdsa',
'0xfdsafdsfdsfdsfds'
]) // update balance for two addresses
setLocale
Onboard will automatically detect the browser locale at runtime, but if you would like to update it manually you can call the setLocale
function:
onboard.state.actions.setLocal('fr_FR')
updateNotify
If you need to update your notify configuration after initialization, you can do that by calling the updateNotify
function:
onboard.state.actions.updateNotify({
desktop: {
enabled: true,
transactionHandler: transaction => {
console.log({ transaction })
if (transaction.eventCode === 'txPool') {
return {
type: 'success',
message: 'Your transaction from #1 DApp is in the mempool'
}
}
},
position: 'bottomLeft'
},
mobile: {
enabled: true,
transactionHandler: transaction => {
console.log({ transaction })
if (transaction.eventCode === 'txPool') {
return {
type: 'success',
message: 'Your transaction from #1 DApp is in the mempool'
}
}
},
position: 'topRight'
}
})
customNotification
Notify can be used to deliver custom DApp notifications by passing a CustomNotification
object to the customNotification
action. This will return an UpdateNotification
type.
This UpdateNotification
will return an update
function that can be passed a new CustomNotification
to update the existing notification.
The customNotification
method also returns a dismiss
method that is called without any parameters to dismiss the notification.
Property | Type | Description |
---|---|---|
message |
string | Customizes the message shown |
eventCode |
string | Allows handling codes in a custom way |
type |
string | Represents the icon type displayed |
autoDismiss |
number | Time (in ms) after which the notification will be dismissed |
link |
string | Adds a link to the transaction hash |
onClick |
function | onClick handler for the notification element |
preflightNotifications
Notify can be used to deliver standard notifications along with preflight updates by passing a PreflightNotificationsOptions
object to the preflightNotifications
API action.
Preflight event types include:
-
txRequest
: Alert user there is a transaction request awaiting confirmation by their wallet -
txAwaitingApproval
: A previous transaction is awaiting confirmation -
txConfirmReminder
: Reminder to confirm a transaction to continue - configurable with thetxApproveReminderTimeout
property; defaults to 15 seconds -
nsfFail
: The user has insufficient funds for transaction (requiresgasPrice
,estimateGas
,balance
,txDetails.value
) -
txError
: General transaction error (requiressendTransaction
) -
txSendFail
: The user rejected the transaction (requiressendTransaction
) -
txUnderpriced
: The gas price for the transaction is too low (requiressendTransaction
)
This API call will return a promise that resolves to the transaction hash (if sendTransaction
resolves the transaction hash and is successful), the internal notification id (if no sendTransaction
function is provided) or return nothing if an error occurs or sendTransaction
is not provided or doesn't resolve to a string.
Example:
const balanceValue = Object.values(balance)[0]
// if using ethers v6 this is:
// ethersProvider = new ethers.BrowserProvider(wallet.provider, 'any')
const ethersProvider = new ethers.providers.Web3Provider(provider, 'any')
const signer = ethersProvider.getSigner()
const txDetails = {
to: toAddress,
value: 100000000000000
}
const sendTransaction = () => {
return signer.sendTransaction(txDetails).then(tx => tx.hash)
}
const gasPrice = () => ethersProvider.getGasPrice().then(res => res.toString())
const estimateGas = () => {
return ethersProvider.estimateGas(txDetails).then(res => res.toString())
}
const transactionHash = await onboard.state.actions.preflightNotifications({
sendTransaction,
gasPrice,
estimateGas,
balance: balanceValue,
txDetails: txDetails
})
console.log(transactionHash)
interface PreflightNotificationsOptions {
sendTransaction?: () => Promise<string | void>
estimateGas?: () => Promise<string>
gasPrice?: () => Promise<string>
balance?: string | number
txDetails?: {
value: string | number
to?: string
from?: string
}
txApproveReminderTimeout?: number // defaults to 15 seconds if not specified
}
updateAccountCenter
If you need to update your Account Center configuration after initialization, you can call the updateAccountCenter
function with the new configuration
onboard.state.actions.updateAccountCenter({
position: 'topRight',
enabled: true,
minimal: true
})
setPrimaryWallet
The primary wallet (first in the list of connected wallets) and primary account (first in the list of connected accounts for a wallet) can be set by using the setPrimaryWallet
function. The wallet that is set needs to be passed in for the first parameter and if you would like to set the primary account, the address of that account also needs to be passed in:
// set the second wallet in the wallets array as the primary
onboard.state.actions.setPrimaryWallet(wallets[1])
// set the second wallet in the wallets array as the primary wallet
// as well as setting the third account in that wallet as the primary account
onboard.state.actions.setPrimaryWallet(
wallets[1],
wallets[1].accounts[2].address
)
When initializing Onboard you define a list of chains/networks that your app supports. If you would like to prompt the user to switch to one of those chains, you can use the setChain
method on an initialized instance of Onboard:
type SetChain = (options: SetChainOptions) => Promise<boolean>
type SetChainOptions = {
chainId: string // hex encoded string
chainNamespace?: 'evm' // defaults to 'evm' (currently the only valid value, but will add more in future updates)
wallet?: string // the wallet.label of the wallet to set chain
rpcUrl?: string // if chain was instantiated without rpcUrl, include here. Used for network requests
token?: string // if chain was instantiated without token, include here. Used for display, eg Ethereum Mainnet
label?: string // if chain was instantiated without label, include here. The native token symbol, eg ETH, BNB, MATIC
}
const success = await onboard.setChain({ chainId: '0x89' })
The setChain
methods takes an options object with a chainId
property hex encoded string for the chain id to switch to. The chain id must be one of the chains that Onboard was initialized with. If the wallet supports programatically adding and switching the chain, then the user will be prompted to do so, if not, then a modal will be displayed indicating to the user that they need to switch chains to continue. The setChain
method returns a promise that resolves when either the user has confirmed the chain switch, or has dismissed the modal and resolves with a boolean indicating if the switch network was successful or not. The setChain
method will by default switch the first wallet (the most recently connected) in the wallets
array. A specific wallet can be targeted by passing in the wallet.label
in the options object as the wallet
parameter. If a chain was instantiated without an rpcUrl, token, or label, add these options for wallets that require this information for adding a new chain.
The Onboard styles can customized via CSS variables. The following properties and their default properties can be customized by adding these variables to the :root
in your CSS file:

Many of the wallet modules require dependencies that are not normally included in browser builds (namely the node builtin modules such as crypto
, buffer
, util
etc). If you are having build issues you can try the following bundler configs to resolve these dependency issues:
Everything should just work since the node built-ins are automatically bundled in v4
You'll need to add some dev dependencies with the following command:
npm i --save-dev assert buffer crypto-browserify stream-http https-browserify os-browserify process stream-browserify util browserify-zlib
Then add the following to your webpack.config.js
file:
const webpack = require('webpack')
module.exports = {
fallback: {
path: require.resolve('path-browserify'),
zlib: require.resolve('browserify-zlib')
},
resolve: {
alias: {
assert: 'assert',
buffer: 'buffer',
crypto: 'crypto-browserify',
http: 'stream-http',
https: 'https-browserify',
os: 'os-browserify/browser',
process: 'process/browser',
stream: 'stream-browserify',
util: 'util'
}
},
experiments: {
asyncWebAssembly: true
},
plugins: [
new webpack.ProvidePlugin({
process: 'process/browser',
Buffer: ['buffer', 'Buffer']

}
CRACO provides a way to override webpack config which is obfuscated in Create React App built applications.
The above webpack 5 example can be used in the craco.config.js
file at the root level in this case.

It seems some component or dependency requires Node's Buffer. To polyfill this, the simplest way I could find was to install the buffer package and include the following in web3-onboard.ts:
import { Buffer } from 'buffer'
globalThis.Buffer = Buffer

Web3-Onboard will work out of the box with npm
