Web

Auth Core is a library that makes it easy to add wallet connection to your dapp. It's intuitive, responsive and customizable.

Introduction

Auth Core can be integrated with any wallet, platform, chain and social login. You can even plug in your existing auth setup.

Wallet management

Auth Core will automatically create a crypto wallet without a private key. The security is guaranteed by MPC (Multi-Party Computing) - based threshold signatures, which is ahead of other technologies.

Customizable

You can tweak the Auth Core to match your branding. You can pick from a few pre-defined accent colors and border-radius configurations. For more advanced use cases, you can provide in a fully custom theme, render your own button, and omit certain features. Dark mode included.

Industry standards

For better interoperability with most products, we support use with web3.js, ethers.js, and viem — the most commonly used libraries in the space.

Installation

Get up and running with Auth Core.

Quick start

You can scaffold a new AuthCore + React app with one of the following commands, using your package manager of choice:


npm init @particle-network/auth-core-modal@latest
# or
pnpm create @particle-network/auth-core-modal@latest
# or
yarn create @particle-network/auth-core-modal

This will prompt you for a project name, generate a new directory containing a boilerplate project, and install all required dependencies.

Alternatively, you can manually integrate Auth Core into your existing project.

Manual setup


yarn add @particle-network/auth-core-modal

Additional build tooling setup

The Webpack v5 bundler used by Create React App no longer provides Node polyfills, so you'll need to include these modules yourself to satisfy AuthCore's peer dependencies. add the below code to webpack config.


{
    resolve: {
        fallback: {
            http: require.resolve('stream-http'),
            https: require.resolve('https-browserify'),
            stream: require.resolve('stream-browserify'),
            assert: require.resolve('assert'),
            zlib: require.resolve('browserify-zlib'),
            url: require.resolve('url'),
        },
        plugins:[
            new webpack.ProvidePlugin({
                Buffer: ["buffer", "Buffer"],
            })
        ]
    }
}

And install dependence packages.


yarn add stream-http https-browserify stream-browserify assert browserify-zlib url

Configure

Init Auth Core with Particle project config, you can get the config from Particle Dashboard.

Wrap your application with AuthCoreContextProvider.


import { AuthCoreContextProvider } from '@particle-network/auth-core-modal';

const App = () => {
    // replace 'xxxx' with particle project config.
    return (
        <AuthCoreContextProvider
            options={{
                projectId: 'xxxx',
                clientKey: 'xxxx',
                appId: 'xxxx',
                promptSettingConfig: { //optional
                    //set payment password prompt: none, first, every, everyAndNotSkip.
                    promptPaymentPasswordSettingWhenSign: PromptSettingType.first,
                    //set master password prompt: none, first, every, everyAndNotSkip.
                    promptMasterPasswordSettingWhenLogin: PromptSettingType.first,
                },
                erc4337: { // optional
                    name: 'SIMPLE',  // support 'SIMPLE', 'CYBERCONNECT', 'BICONOMY'
                    version: '1.0.0',
                },
                wallet: {
                    visible: true,  //show wallet entrance when connect success.
                }
            }}
        >
            <YourApp />
        </AuthCoreContextProvider>
    );
};

ERC-4337

Auth Core Modal will display smart account address and badge when set erc4337 param, you can use smart account send gasless transaction, refer to Account Abstraction.

Embedded Wallet

A fully functional wallet will be embedded in your web page when you set param wallet, and you can custom Wallet UI style to match your branding.

Now, you can use Auth Core in your app.

Usage

Auth Core is implemented based on React, provides a rich set of hook functions and custom components.

Connect Wallet

Custom you own connect button and call connect function to connect Auth Core.


import { useConnect } from '@particle-network/auth-core-modal';

const { connect, disconnect, connectionStatus, requestConnectCaptcha } = useConnect();

// open modal and connect 
const userInfo = await connect();

// connect with email.
const userInfo = await connect({
    email: 'xxx@xx.com',
    code: 'xxxxxx', // optional
});

// connect with phone.
const userInfo = await connect({
    phone: '+1xxxxxxxx', //E.164 format
    code: 'xxxxxx', // optional
});

// connect with social type.
const userInfo = await connect({
    socialType: 'google',
    prompt: 'select_account', //optional, only google, discord and microsoft support it.
});

// connect with JWT.
const userInfo = await connect({
    jwt: 'xxxxxxxxxx'
});

For using a email/phone connect wallet, you can custom UI and get code by requestConnectCaptcha.

For using social connect wallet, you can specify the prompt param. prompt is A space-delimited list of string values that specifies whether the authorization server prompts the user for reauthentication and consent. The possible values are:

none
The authorization server does not display any authentication or user consent screens; it will return an error if the user is not already authenticated and has not pre-configured consent for the requested scopes. You can use none to check for existing authentication and/or consent.
consent
The authorization server prompts the user for consent before returning information to the client.
select_account
The authorization server prompts the user to select a user account. This allows a user who has multiple accounts at the authorization server to select amongst the multiple accounts that they may have current sessions for.

If no value is specified and the user has not previously authorized access, then the user is shown a consent screen.

Connect with specified chain


import { BNBChain } from '@particle-network/chains';

// connect with social type.
const userInfo = await connect({
    socialType: 'google',
    prompt: 'select_account', //optional
    chain: BNBChain,
});

Connect and authorize

When connect Auth Core, Sign-In with Ethereum(EVM) or signMessage(Solana) will auto run.


import { BNBChain } from '@particle-network/chains';

// connect with social type.
const userInfo = await connect({
    socialType: 'google',
    prompt: 'select_account', //optional
    chain: BNBChain,
    authorization: {
        uniq: true,  // uniq sign
        message: 'base58 string', // solana need it, evm will ignore it
    }
});
// get authorize signature
const signature = userInfo.signature;

Disconnect

The user wallet local information will be deleted.


import { useConnect } from '@particle-network/auth-core-modal';

const { disconnect } = useConnect();
// disconnect
await disconnect();

EVM Chains

Ecdsa Wallet will be created when connect with EVM chains.


import { useEthereum } from '@particle-network/auth-core-modal';

const { provider,   // eip1193 provider
        address,    // evm wallet public address
        chainId,    // current chain
        chainInfo,
        switchChain,
        signMessage,
        signTypedData,
        sendTransaction,
        enable } = useEthereum();

// send transaction.
const txHash = await sendTransaction({
    to: '0xe8fc0baE43aA264064199dd494d0f6630E692e73',
    value: '1000000',
});

// sign message.
const signature = await signMessage(message);

// sign typed data
const signature = await signTypedData(typedData);

// switch chain to Ethereum Mainnet, chainId: number or prefixed hex string
await switchChain('0x1')

It is easy to use hook methods, you can also set provider to web3.js / ethers.js / viem and use third-party lib api.

Create wallet manually

If you connect Auth Core with Solana chain, the EVM wallet will not be created, and the address will return null. You can create wallet manually.


import { useEthereum } from '@particle-network/auth-core-modal';

const { address, enable } = useEthereum();

if (!address) {
    await enable();
}

Solana

EdDsa Wallet will be created when connect with Solana.


import { useSolana } from '@particle-network/auth-core-modal';

const { address,  // solana public address
        chainId,  // solana current chain id
        chainInfo,
        switchChain,
        signMessage,
        signTransaction,
        signAllTransactions,
        signAndSendTransaction,
        enable } = useSolana();

// send transaction.
const txHash = await signAndSendTransaction(txData);

// sign message.
const signature = await signMessage(message);

Create wallet manually

If you connect Auth Core with EVM chain, the Solana wallet will not be created, and the address will return null. You can create wallet manually.


import { useSolana } from '@particle-network/auth-core-modal';

const { address, enable } = useSolana();

if (!address) {
    await enable();
}
