A library that holds the core functional logic of a dapp on the MultiversX blockchain
See Dapp template for live demo or checkout usage in the Github repo
The library can be installed via npm or yarn.
npm install @multiversx/sdk-dapp
or
yarn add @multiversx/sdk-dapp
If you need only the sdk-dapp basic logic, without the additional UI, consider using the --no-optional
flag.
This will not install the packages needed for the optional UI components.
npm install @multiversx/sdk-dapp --no-optional
or
yarn add @multiversx/sdk-dapp --no-optional
If you're transitioning from dapp-core 1.x to @multiversx/sdk-dapp (dapp-core 2.0), please read the Migration guide
As of @multiversx/[email protected] Node >=18 is required since Node 16 reached its EOL.
sdk-dapp aims to abstract and simplify the process of interacting with users' wallets and with the MultiversX blockchain, allowing developers to easily get started with a new application or integrate sdk-dapp into an existing application.
This library covers two main areas: User Identity and Transactions. The API for interacting with library's logic is exposed via hooks and methods that can be called for logging in the user, getting the status of the user or sending transactions.
However, to simplify usage even further, the library also comes with a default UI that already uses these hooks and methods under the hood. These UI elements can be easily customized with custom css classes.
The default UI is exposed via the UI
module.
import * as DappUI from "@multiversx/sdk-dapp/UI";
Please be aware that this style of importing might also import unused code.
To reduce the amount of dead code, you can use named imports for each component like
import { UnlockPage } from '@multiversx/sdk-dapp/UI/pages';
or;
import { UnlockPage } from '@multiversx/sdk-dapp/UI/pages/UnlockPage';
There are a couple of requirements that need to be met for the application to work properly.
If you experience bugs, please make sure that you read these, before opening an issue
React
This library was built for applications that use React, it might not be suitable for usage with other libraries or frameworks.
DappProvider
You need to wrap your application with the DappProvider component, which is exported by the library, as we need to create a global Context to be able to manipulate the data.
- import the Provider:
import { DappProvider } from '@multiversx/sdk-dapp/wrappers/DappProvider';
or;
import { DappProvider } from '@multiversx/sdk-dapp/wrappers';
- Wrap your application with this Provider.
<DappProvider
environment="devnet"
customNetworkConfig={customNetworkConfig} // optional
dappConfig={dappConfig} // optional
>
environment
is a required key that is needed to configure the app's endpoints for a specific environment. Accepted values are testnet
, devnet
and mainnet
(also configured in EnvironmentsEnum
)
DappProvider also accepts an optional customNetworkConfig
object with a couple of keys.
This allows using different APIs and different connection providers to configure your network configuration.
All keys are optional
{
id?: string;
name?: string;
egldLabel?: string;
decimals?: string;
digits?: string;
gasPerDataByte?: string;
walletConnectDeepLink?: string; // a string that will create a deeplink for an application that is used on a mobile phone, instead of generating the login QR code.
walletConnectV2ProjectId?: string; // a unique ProjectID needed to access the WalletConnect 2.0 Relay Cloud
walletAddress?: string;
apiAddress?: string;
explorerAddress?: string;
apiTimeout?: 4000;
}
DappProvider also accepts an optional dappConfig
object.
{
logoutRoute?: string; // a route to redirect after auto-logout (session expired, native auth token expired or idle app)
}
UI Wrappers
The library exposes a couple of Components that are connected to the redux store and are used to display various elements when something happens inside the app:
TransactionsToastList
will display new transactions in nice toasts at the bottom of the screen. This component is fully customizable.
import {TransactionsToastList} from "@multiversx/sdk-dapp/UI/TransactionsToastList";
// all properties are optional
<TransactionsToastList
className = 'transactions-toast-list'
transactionToastClassName="transactions-toast-class"
successfulToastLifetime={30000}
parentElement={
/*
React NodeElement where the toast will be rendered
*/
}
/>
SignTransactionsModals
will show a modal when a new transaction is submitted, prompting the user to verify and sign it.
Important! This is required to make transactions work, except when you use hooks to sign the transactions manually (more on this below).
import { SignTransactionsModals } from '@multiversx/sdk-dapp/UI/SignTransactionsModals';
<App>
<SignTransactionsModals />
<Content />
</App>;
NotificationModal
Will show a modal to the user with various warnings and errors.
import { NotificationModal } from '@multiversx/sdk-dapp/UI/NotificationModal';
<App>
<NotificationModal />
<Content />
</App>;
If you want to show custom notifications, you can use the useGetNotification
hook to get the notifications (like insufficient funds, errors etc).
sdk-dapp makes logging in and persisting user's session easy and hassle-free.
A handy component is AuthenticatedRoutesWrapper, which can be used to protect certain routes and redirect the user to login page if the user is not authenticated.
Import from sdk-dapp:
import { AuthenticatedRoutesWrapper } from '@multiversx/sdk-dapp/wrappers/AuthenticatedRoutesWrapper';
or;
import { AuthenticatedRoutesWrapper } from '@multiversx/sdk-dapp/wrappers';
Use with routes:
<AuthenticatedRoutesWrapper routes={routes} unlockRoute='/unlock'>
{appContent}
</AuthenticatedRoutesWrapper>
routes should be an array with objects with a signature similar to this:
{
path: "/dashboard",
title: "Dashboard",
component: Dashboard,
authenticatedRoute: true,
}
The important parts that makes this component work are the flag authenticatedRoute: true and the key path, which means that this route should be accessible only to authenticated users.
Login UI
There are a couple of very handy React components that can be used to login the user and protect certain routes if the user is not logged in.
Under the DappUI
object mentioned above, you can find 4 buttons (one for each provider) which abstract away all the logic of loggin in the user and render the default UI. These buttons can be easily customized with a custom css class.
The exported buttons are:
- ExtensionLoginButton
- WalletConnectLoginButton
- LedgerLoginButton
- WebWalletLoginButton
example:
<ExtensionLoginButton
callbackRoute='/dashboard'
buttonClassName='extension-login'
loginButtonText='Extension login'
/>
They can also be used with children
<ExtensionLoginButton
callbackRoute="/dashboard"
buttonClassName="extension-login"
loginButtonText="Extension login"
>
<>
<icon/>
<p>Login text</p>
<>
</ExtensionLoginButton>
WalletConnectLoginButton
and LedgerLoginButton
will trigger a modal with a QR code and the ledger login UI, respectively.
These are automatically triggered by the buttons.
If, however, you want access to these containers without the buttons, you can easily import and use them.
<WalletConnectLoginContainer
callbackRoute={callbackRoute}
loginButtonText='Login with xPortal'
title='xPortal Login'
className='wallect-connect-login-modal'
lead='Scan the QR code using xPortal'
wrapContentInsideModal={wrapContentInsideModal}
redirectAfterLogin={redirectAfterLogin}
token={token}
onLoginRedirect={onLoginRedirect}
onClose={onClose}
/>
<LedgerLoginContainer
callbackRoute={callbackRoute}
className='ledger-login-modal'
wrapContentInsideModal={wrapContentInsideModal}
redirectAfterLogin={redirectAfterLogin}
nativeAuth
onClose={onClose}
onLoginRedirect={onLoginRedirect}
/>
<WebWalletLoginButton
callbackRoute="/dashboard"
loginButtonText="Web Wallet login"
>
If you have a custom Web Wallet provider you can integrate it by using the customWalletAddress
prop:
<WebWalletLoginButton
callbackRoute="/dashboard"
loginButtonText="Custom Web Wallet login"
customWalletAddress="https://custom-web-wallet.com"
>
All login buttons and hooks accept a prop called redirectAfterLogin
which specifies of the user should be redirected automatically after login.
The default value for this boolean is false, since most apps listen for the "isLoggedIn" boolean and redirect programmatically.
If you need to authenticate some requests, you can provide the nativeAuth
flag to your login buttons. It comes as a boolean or as a configuration object. This token will be available in useGetLoginInfo
hook later, inside tokenLogin.nativeAuthToken
. If you need to use an interceptor for your requests, make sure to check out the implementation of AxiosInterceptorContext
. Use it like:
import { AxiosInterceptorContext } from '@multiversx/sdk-dapp/wrappers/AxiosInterceptorContext';
<AxiosInterceptorContext.Provider>
<AxiosInterceptorContext.Interceptor
authenticatedDomanis={['https://my-api.com']}
>
<Router>
<DappProvider environment={EnvironmentsEnum.devnet}>
<>
<AxiosInterceptorContext.Listener />
{/*
// other components below
*/}
<TransactionsToastList />
<NotificationModal />
<SignTransactionsModals />
<Routes>...</Routes>
</>
</DappProvider>
</Router>
</AxiosInterceptorContext.Interceptor>
</AxiosInterceptorContext.Provider>
Another handly component is AuthenticatedRoutesWrapper, which can be used to protect certain routes and redirect the user to login page if the user is not authenticated.
Import from sdk-dapp:
import { AuthenticatedRoutesWrapper } from '@multiversx/sdk-dapp/wrappers/AuthenticatedRoutesWrapper';
Use with routes:
<AuthenticatedRoutesWrapper routes={routes} unlockRoute={routeNames.unlock}>
{appContent}
</AuthenticatedRoutesWrapper>
routes should be an array with objects with a signature similar to this:
{
path: "/dashboard",
title: "Dashboard",
component: Dashboard,
authenticatedRoute: true,
}
The important parts that makes this component work are the flag authenticatedRoute: true and the key path, which means that this route should be accessible only to authenticated users.
Login hooks
This area covers the login hooks, which expose a trigger function and the login data, ready to be rendered.
These hooks are exposed as named exports, which can be imported from sdk-dapp:
import {
useExtensionLogin,
useWalletConnectV2Login,
useLedgerLogin,
useWebWalletLogin
} from '@multiversx/sdk-dapp/hooks';
or;
import { useExtensionLogin } from '@multiversx/sdk-dapp/hooks/login/useExtensionLogin';
import { useWalletConnectV2Login } from '@multiversx/sdk-dapp/hooks/login/useWalletConnectV2Login';
import { useLedgerLogin } from '@multiversx/sdk-dapp/hooks/login/useLedgerLogin';
import { useWebWalletLogin } from '@multiversx/sdk-dapp/hooks/login/useWebWalletLogin';
There are 4 available hooks:
- useExtensionLogin
- useWalletConnectV2Login
- useLedgerLogin
- useWebWalletLogin
All hooks have the same response signature:
return type is as follows:
const [initiateLogin, genericLoginReturnType, customLoginReturnType] =
useLoginHook({
callbackRoute,
token,
nativeAuth,
onLoginRedirect
});
- initiateLogin is a function that needs to be called for the login flow to be initiated;
- genericLoginReturnType is an object that is exactly the same for all hooks:
{
error: string,
loginFailed: boolean,
isLoading: boolean,
isLoggedIn: boolean
}
-
customLoginReturnType is an object that is custom for each hook and returns specific data for that login:
-
null for useExtensionLogin;
-
null for useWebWalletLogin;
-
{ uriDeepLink: string, qrCodeSvg: svgElement }
for useWalletConnectV2Login;
-
{
accounts: string[];
showAddressList: boolean;
startIndex: number;
selectedAddress: SelectedAddress | null;
onGoToPrevPage: () => void;
onGoToNextPage: () => void;
onSelectAddress: (address: SelectedAddress | null) => void;
onConfirmSelectedAddress: () => void;
}
for useLedgerLogin;
Reading User State
Once logged in, the user's session is persisted and can be read and deleted via a couple of handy functions.
For logging out, the library exposes a simple function called logout, which can be called to clear the user data.
the function accepts 2 arguments:
callbackUrl: string (optional)
the url to redirect the user to after logging him outonRedirect: (callbackUrl: string) => void (optional)
a function that will be called instead of redirecting the user. This allows you to control how the redirect is done, for example, with react-router-dom, instead of window.location.href assignment. Important this function will not be called for web wallet logout
You can opt-in for using the useIdleTimer
hook, which logs out the user after a period of inactivity (default set to 10 minutes). Optionally it accepts an onLogout
function that fulfills your dapp's specific logout business logic. Make sure to call the above logout
function inside this onLogout
callback.
You can also opt-in for using the useRegisterWebsocketListener
hook. The hooks accepts a callback which will get fired once a websocket message is received, receiving the string
argument provided by the event. Optionally you can simply listen to changes on account/transactions with the useGetWebsocketEvent
hook.
There are 2 ways of reading the user current state: hooks (to be used inside components and for reacting to changes in the data) and simple functions (for reading data outside of React components or inside handlers).
- hooks:
useGetLoginInfo, useGetAccountInfo, useGetNetworkConfig, useGetWebsocketEvent
; - functions:
getAccount, getAccountBalance, getAccountShard, getAddress, getIsLoggedIn;
The sdk-dapp library exposes a straight-forward way of sending transactions and tracking their status, with a couple of handy UI components;
Sending Transactions
The API for sending transactions is a function called sendTransactions:
import { sendTransactions } from "@multiversx/sdk-dapp";
It can be used to send a transaction with minimum information:
const { sessionId, error } = await sendTransactions({
transactions: [
{
value: '1000000000000000000',
data: 'ping',
receiver: contractAddress
},
],
callbackRoute?: string // (optional, defaults to window.location.pathname) the route to be redirected to after signing. Will not redirect if the user is already on the specified route;
transactionsDisplayInfo: TransactionsDisplayInfoType // (optional, default to null) custom message for toasts texts;
minGasLimit?: number (optional, defaults to 50_000);
sessionInformation?: any (optional, defaults to null) extra sessionInformation that will be passed back to you via getSignedTransactions hook;
signWithoutSending?: boolean // (optional, defaults to false), the transaction will be signed without being sent to the blockchain;
completedTransactionsDelay?: number // delay the transaction status from going into "successful" state;
redirectAfterSigning?: boolean // (optional, defaults to true), whether to redirect to the provided callbackRoute;
});
It returns a Promise that will be fulfilled with {error?: string; sessionId: string | null;}
sessionId
is the transaction's batch id which can be used to track a transaction's status and react to it.
Important! For the transaction to be signed, you will have to use either SignTransactionsModals
defined above, in the Prerequisites
section,
or the useSignTransactions
hook defined below. If you don't use one of these, the transactions won't be signed
Sending sync transactions in batches (batch transactions mechanism)
The API for sending sync transactions is a function called sendBatchTransactions:
import { sendBatchTransactions } from "@multiversx/sdk-dapp/services/transactions/sendBatchTransactions";
It can be used to send a group of transactions (that ca be synchronized) with minimum information:
const { batchId, error } = await sendBatchTransactions({
transactions: [
[
{
value: '1000000000000000000',
data: 'tx1',
receiver: receiverAddress
},
],
[
{
value: '1000000000000000000',
data: 'tx2',
receiver: receiverAddress
},
{
value: '1000000000000000000',
data: 'tx3',
receiver: receiverAddress
},
]
],
/**
* the route to be redirected to after signing. Will not redirect if the user is already on the specified route
* @default window.location.pathname
*/
callbackRoute?: string;
/**
* custom message for toasts texts
* @default null
*/
transactionsDisplayInfo: TransactionsDisplayInfoType;
/**
* Minimum amount of gas in order to process the transaction.
* @default 50_000
*/
minGasLimit?: number (optional, defaults to 50_000);
/**
* Contains extra sessionInformation that will be passed back via getSignedTransactions hook
*/
sessionInformation?: any (optional, defaults to null)
/**
* The transactions will be signed without being sent to the blockchain
*/
signWithoutSending?: boolean;
/**
* Delay the transaction status from going into "successful" state
*/
completedTransactionsDelay?: number;
/**
* If true, redirects to the provided callbackRoute
*/
redirectAfterSigning?: boolean;
});
It returns a Promise that will be fulfilled with {error?: string; batchId: string | null;}
batchId
is the transactions' batch id used to send the batch to the batch service and to track the transactions status and react to it. This is composed by thesessionId
(received after signing) and the user address. Eg.12123423123-erd1address...
.error
is the error that can appear during the signing/sending process.
sendBatchTransactions
accepts an argument transactions
which is an array of transactions arrays.
Each transaction array will be sent to the blockchain in the order they are provided.
Having the example above, the transactions will be sent in the following order:
tx1
tx2, tx3
tx1
will be sent first, waits until is completed, then tx2
and tx3
will be sent in parallel. This means that the groups are sent synchronously, but the transactions inside a group are sent in parallel.
** Important! This function will send the transactions automatically in batches, based on the provided transactions array, immediately after signing.
If you do not want them to be sent automatically, but on demand, then you should use send callback exposed by the useSendBatchTransactions
hook.
Be sure to save the sessionId
passed to the batch. We recommend to generate a new sessionId like this: Date.now().toString();
**
import { sendBatchTransactions } from '@multiversx/sdk-dapp/services/transactions/sendBatchTransactions';
import { useSendBatchTransactions } from '@multiversx/sdk-dapp/hooks/transactions/batch/useSendBatchTransactions';
const { send: sendBatchToBlockchain } = useSendBatchTransactions();
// Use signWithoutSending: true to sign the transactions without sending them to the blockchain
sendBatchTransactions({
transactions,
signWithoutSending: true,
callbackRoute: window.location.pathname,
redirectAfterSign: true
});
const { error, batchId, data } = await sendBatchToBlockchain({
transactions,
sessionId
});
Important! For the transaction to be signed, you will have to use either SignTransactionsModals
defined above, in the Prerequisites
section,
or the useSignTransactions
hook defined below. If you don't use one of these, the transactions won't be signed
Transaction Signing Flow
Once a transaction has been submitted, you have to use either the SignTransactionsModals
or the useSignTransactions
hook,
for the user to be prompted in his provider (Extension, xPortal App etc) to sign the transaction.
If you don't want to use the default modals that appear for the user when the signing process happens,
you have to use the useSignTransactions
hook to sign those transactions.
const {
callbackRoute,
transactions,
error,
sessionId,
onAbort,
hasTransactions,
canceledTransactionsMessage
} = useSignTransactions();
This hook will let you know if there are any transactions and you can programmatically abort the signing process.
We suggest displaying a message on the screen that confirms the transaction that needs to be signed.
You can also get the provider via
const { providerType, provider } = useGetAccountProvider();
and use that to display an appropriate message to the user.
For ledger, signing a transaction is simple if you're using the SignTransactionsModal
component.
It is fully customizable and will take care of walking the user through the signing flow.
If, however, you want to implement a different experience, you will have to use the useSignTransactionsWithLedger
hook.
it accepts the following props:
{
onCancel: () => void;
}
and returns an object with the following keys:
{
onSignTransaction: () => void;
onNext: () => void;
onPrev: () => void;
waitingForDevice: boolean;
onAbort: (e: React.MouseEvent) => void;
isLastTransaction: boolean;
currentStep: number;
signedTransactions?: Record<string, Transaction>;
currentTransaction: {
transaction: Transaction;
transactionTokenInfo: {
tokenId: string;
amount: string;
receiver: string;
type?: string;
nonce?: string;
multiTxData?: string;
};
isTokenTransaction: boolean;
tokenDecimals: number;
dataField: string;
};
}
Tracking a transaction
The library has a built-in implementation for tracking the transactions sent normally or synchronously via batch transactions.
Also, exposes a hook called useTrackTransactionStatus
;
There is a TransactionTracker
component that is used to track transactions. It is used by default in the DappProvider
component.
This component is using the useTransactionsTracker
and useBatchTransactionsTracker
hooks to track the transactions.
useTransactionsTracker
- track transactions sent normally
useBatchTransactionsTracker
track batch transactions
The developers are be able to create their own implementation for the transaction tracking component (using these hooks or creating their own logic) and pass it to the DappProvider
component through customComponents
field.
import { TransactionsTracker } from "your/module";
<DappProvider
environment={environment}
customNetworkConfig={{
name: 'customConfig',
apiTimeout,
walletConnectV2ProjectId
}}
customComponents={{
transactionTracker: {
component: TransactionsTracker,
props: {
onSuccess: (sessionId) => {
console.log(`Session ${sessionId} successfully completed`);
},
onFail: (sessionId, errorMessage) => {
if (errorMessage) {
console.log(`Session ${sessionId} failed, ${errorMessage}`);
return;
}
console.log(`Session ${sessionId} failed`);
}
}
}
}}
>
The props passed to the TransactionsTracker
component are:
export interface TransactionsTrackerType {
getTransactionsByHash?: GetTransactionsByHashesType;
onSuccess?: (sessionId: string | null) => void;
onFail?: (sessionId: string | null, errorMessage?: string) => void;
}
Also, the same props can be passed to the useTransactionsTracker
and useBatchTransactionsTracker
hooks.
import { useBatchTransactionsTracker } from 'hooks/transactions/batch/tracker/useBatchTransactionsTracker';
import { useTransactionsTracker } from 'hooks/transactions/useTransactionsTracker';
const props = {
onSuccess: (sessionId) => {
console.log(`Session ${sessionId} successfully completed`);
},
onFail: (sessionId, errorMessage) => {
if (errorMessage) {
console.log(`Session ${sessionId} failed, ${errorMessage}`);
return;
}
console.log(`Session ${sessionId} failed`);
}
};
useTransactionsTracker(props);
useBatchTransactionsTracker(props);
The transactions trackers will automatically update the transactions statuses in the store. This functionality is used by the TransactionToastList
component to display the transactions statuses.
import {useTrackTransactionStatus} from @multiversx/sdk-dapp/hooks;
const transactionStatus = useTrackTransactionStatus({
transactionId: sessionId,
onSuccess,
onFail,
onCancelled,
});
transactionStatus has the following information about the transaction:
{
isPending,
isSuccessful,
isFailed,
isCancelled,
errorMessage,
status,
transactions;
}
It's safe to pass in null
as a sessionId, so if the transaction wasn't yet sent, the hook will just return an empty object.
Tracking transactions' statuses
sdk-dapp also exposes a number of handy hooks for tracking all, pending, failed, successful and timed out transactions.
Use:
useGetPendingTransactions
to get a list of all pending transactions.useGetSuccessfulTransactions
to get a list of all successful transactions.useGetFailedTransactions
to get a list of all pending transactions.
An especially useful hook called useGetActiveTransactionsStatus
will keep you updated with the status
of all transactions at a certain point in time.
it's return signature is
{
pending: boolean, // at least one transaction is pending;
hasPendingTransactions: boolean, // the user has at least 1 pending transaction active;
timedOut: boolean, // there are no pending transactions and at least one has timed out;
fail: boolean, // there are no pending and no timedOut transactions and at least one has failed;
success: boolean, // all transactions are successful and all smart contract calls have been processed successfully;
}
Transaction Toasts UI
sdk-dapp also exposes a toast component for tracking transactions that uses the above mentioned hooks and displays toasts with transactions statuses.
The toasts list is exposed via TransactionsToastList UI component and can be used just by rendering it inside the application.
TransactionToastList
component renders also custom toasts. A custom toast can be added using the util function: addNewCustomToast
and can be removed using deleteCustomToast
When TransactionToastList
is also used for displaying custom toasts, is enough to call addNewCustomToast
to add new custom toast to the list;
<App>
<Router />
<TransactionsToastList />
</App>
Important: This has to be inside the <DappProvider/>
children.
In case you don't want to use TransactionToastList
and just display a custom toast, then you have to import CustomToast
component
const customToast = addNewCustomToast(
{
toastId: 'toast-id',
message: '',
type: 'custom',
duration: 2000
}
);
<CustomToast
{...customToast}
onDelete: () => deleteCustomToast(toastId)
/>
Removing transactions manually
sdk-dapp takes care to change transactions' statuses and removes them when needed, but if you need to do this manually, you can use the exposed functions for this:
removeTransactionsToSign(sessionId);
removeSignedTransaction(sessionId);
removeAllTransactionsToSign();
removeAllSignedTransactions();
The sdk-dapp library exposes bundles for both CommonJS and ESModules, however, in some environments, Jest might require manual mapping of the CommonJS output. To implement it, add the following snippet inside your jest config file.
moduleNameMapper: {
'@multiversx/sdk-dapp/(.*)':
'<rootDir>/node_modules/@multiversx/sdk-dapp/__commonjs/$1.js'
}
Since version 2.0, sdk-dapp does not have a default export object. You have to import everything from its own separate module. Below you can find all the exports.
You can either import everything from a module, or if you really want to make sure you're not importing anything that is not used, you can import everything from its own file.
You can either go into their specific folder in the module for extra trimming, or import everything together.
for example, these 2 imports are both valid:
import {
useExtensionLogin,
useGetAccountInfo
} from '@multiversx/sdk-dapp/hooks';

We are aware that there are projects out there that would like to use this library to allow users to seamlessly authenticate with the xPortal App.
You can use this library for its utility functions, like "formatAmount, parseAmount", mnemonic words list or its constants.
However, certain architectural decisions that we made do not work out of the box with React Native runtime (neither Metro nor Re.pack). Due to this, you cannot yet use the DappProvider wrapping logic in a React Native application.
We have a couple of solutions in mind and are actively working on exploring ways to overcome these limitations. Until then, you can use @multiversx/erdjs libraries and @walletconnect to connect to the xPortal App. There are also guide for doing this from the community
If you are using Next.js, make sure to check out the README and implementation of the Next.js Template dApp.
Starting with the 2.0 version of the dApp SDK ( previously @elrondnetwork/[email protected]
) and @multiversx/[email protected]
WalletConnect 2.0 is available as a login and signing provider, allowing users to login by scanning a QR code with the Mobile App
This is an implementation of sdk-wallet-connect-provider ( docs ) signing provider
As a ProjectID is needed for the complete functionality, the following change is needed:
In the DappProvider wrapper a walletConnectV2ProjectId
must be provided in the customNetworkConfig
The Project ID can be generated for free here: https://cloud.walletconnect.com/sign-in
<DappProvider
environment="devnet"
customNetworkConfig={{
name: 'customConfig',
walletConnectV2ProjectId: '9b1a9564f91...'
}}
>
The WalletConnect Project ID grants you access to the WalletConnect Cloud Relay that securely manages communication between the device and the dApp.
If the Project ID is valid, the new functionality will work out of the box with the Transactions and Message signing flows.
