This documentation for the Particle Network Javascript SDK will get you started in minutes!
Particle Network SDK allows you to easily integrate your app with the EVM and Solana blockchain, whether you already have a dApp integrated with web3 or are starting from scratch. Particle Network provides a smooth and delightful experience for both you and your app's users.
Download Particle Network SDK to your project via Yarn
yarn add @particle-network/auth
​
//if you need support evm-chains
yarn add @particle-network/provider
​
//if you need support solana chain
yarn add @particle-network/solana-wallet

<!-- Optional: Add EVM Chains suport -->
<script src="https://static.particle.network/sdks/web/provider/0.8.0/provider.min.js"></script>
<!-- Optional: Add Solana Chain suport -->

Before you can add Auth Service to your app, you need to create a Particle project to connect to your app. Visit Particle Dashboard to learn more about Particle projects and apps.
import { ParticleNetwork, WalletEntryPosition } from "@particle-network/auth";
import { ParticleProvider } from "@particle-network/provider";
import { SolanaWallet } from "@particle-network/solana-wallet";
import Web3 from "web3";
​
const pn = new ParticleNetwork({
projectId: "xx",
clientKey: "xx",
appId: "xx",
chainName: "Ethereum", //optional: current chain name, default Ethereum.
chainId: 1, //optional: current chain id, default 1.
wallet: { //optional: by default, the wallet entry is displayed in the bottom right corner of the webpage.
displayWalletEntry: true, //show wallet entry when connect particle.
defaultWalletEntryPosition: WalletEntryPosition.BR, //wallet entry position
supportChains: [{ id: 1, name: "Ethereum"}, { id: 5, name: "Ethereum"}], // optional: web wallet support chains.
customStyle: {}, //optional: custom wallet style
}
});
​
const particleProvider = new ParticleProvider(pn.auth);
//if you need support solana chain
const solanaWallet = new SolanaWallet(pn.auth);
​
//if you use web3.js
window.web3 = new Web3(particleProvider);
window.web3.currentProvider.isParticleNetwork // => true
​
//if you use ethers.js
import { ethers } from "ethers";
const ethersProvider = new ethers.providers.Web3Provider(providerProvider, "any");
const ethersSigner = ethersProvider.getSigner();
Your first Particle Network dApp! 🎉 You can implement web3 functionalities just like how you would normally with MetaMask.
import { ParticleNetwork } from "@particle-network/auth";
​
// open security account settings
const pn = new ParticleNetwork({...});
pn.auth.accountSecurity().catch((error) => {
if (error.code === 4011) {
//ignore window close
} else if (error.code === 10005) {
//invalid token
} else if (error.code === 8005) {
//user not login
}
});
If you use
window.ethereum to call RPC, The following things need to be noted:Use only the Particle wallet and block other plugin wallets. For example, you can directly replace the global variable window.ethereum injected by the Metamask plugin with particleProvider:
window.ethereum = particleProvider;
The Particle wallet co-exists with other plug-in wallets. You can create a new Provider object when switching wallets, avoiding contamination of Particle or Ethereum with assignment operations：
let provider = Object.create(particleProvider);
const ParticleWallet = document.getElementById("ParticleWallet");
const MetaMaskWallet = document.getElementById("MetaMaskWallet");
ParticleWallet.onclick = async () => {
provider = Object.create(particleProvider);
ethersProvider = new ethers.providers.Web3Provider(provider, "any");
};
MetaMaskWallet.onclick = async () => {
if (window.ethereum) {
provider = Object.create(window.ethereum);
}
ethersProvider = new ethers.providers.Web3Provider(provider, "any");
};
const accounts = await provider.request({
method: "eth_requestAccounts",
});
import { ParticleNetwork } from "@particle-network/auth";
​
//ethereum Kovan test net
const pn = new ParticleNetwork({
projectId: "xx",
clientKey: "xx",
appId: "xx",
chainName: "Ethereum",
chainId: 1, //mainnet
});
​
//bsc testnet
const pn = new ParticleNetwork({
projectId: "xx",
clientKey: "xx",
appId: "xx",
chainName: "BSC",
chainId: 56, // mainnet
});
​
//...
In order for web3 to work and grab the end-users' Ethereum wallet addresses, the users have to login first (similar to unlocking account in MetaMask). You can simply trigger the login for users with the web3 function call below.
import { ParticleNetwork } from "@particle-network/auth";
import Web3 from "web3";
​
const pn = new ParticleNetwork({...});
​
// Request user login if needed, returns current user info
pn.auth.login()
​
// optional: custom login params.
// support auth types: email,phone,facebook,google,apple,discord,github,twitch,microsoft,linkedin
pn.auth.login({
// when set social login auth type, will open thirdparty auth page directly.
preferredAuthType?: AuthType,
// when set email/phone account and preferredAuthType is email or phone,
// Particle Auth will enter directly input verification code page.
// when set JWT value and preferredAuthType is jwt, Particle Auth will auto login.
account?: string,
supportAuthTypes?: string, //need support social login types, split with ','. default value 'all'.
loginFormMode?: boolean, // login form mode will hide others ui except login form. only support supportAuthTypes equals email or phone.
hideLoading?: boolean, //hide particle loading when use jwt authorization.
socialLoginPrompt?: string, //social login prompt. none | consent | select_account
})
Login with Phone and input verification code directly.
pn.auth.login({
preferredAuthType: 'phone',
account: '+14155552671', //phone number must use E.164
});
Login with Social Account.
pn.auth.login({
preferredAuthType: 'google', //support facebook,google,apple,discord,github,twitch,microsoft,linkedin etc.
socialLoginPrompt: 'none', //default vaue is none
})
Login with JWT
pn.auth.login({
preferredAuthType: 'jwt',
account: 'JWT Value',
hideLoading: true, //optional: hide particle loading when login.
})
User login modal can also be triggered through web3 accounts.
import Web3 from "web3";
​
// Async functions that triggers login modal, if user not already logged in
web3.eth.getAccounts((error, accounts) => {
if (error) throw error;
console.log(accounts); // ['0x...']
});
A modal will open to ask users to sign up for an account or login with their mobile phone number/email or social account.
If you have replaced your web3 provider with Particle Network provider, nothing needs to be changed for web3 send Ether transactions to continue working.
The Particle Network X modal will pop open and ask users to confirm their transaction once this web3 function is called on the client-side.
const txnParams = {
from: "0xXX",
to: toAddress,
value: sendValue
};
window.web3.eth.sendTransaction(txnParams, (error, txnHash) => {
if (error) throw error;
console.log(txnHash);
});
​
//for solana chain
solanWallet.signAndSendTransaction(transaction)
​
This is a relatively advanced use case. If you use the signed typed data JSON RPC endpoint, Particle Network will support this as well.

​
const pn = new ParticleNetwork({...});
​
// Need check login state when open wallet.
// To set target and features for custom window style, same as window.open().
pn.openWallet(target?: string, features?: string)
​
​
//open wallet in iframe.
const url = pn.buildWalletUrl({
//optional: left top menu style, close or fullscreen
//"fullscreen": wallet will be fullscreen when user click.
//"close": developer need handle click event
topMenuType: "close"
});
​
const iframe = document.createElement("iframe");
iframe.src = url;
//if topMenuType is "close"
window.addEventListener("message", (event) => {
if (event.data === "PARTICLE_WALLET_CLOSE_IFRAME") {
//close click event
}
})
​
When initializing the Particle is complete, you can open the Buy Tokens page.
import { ParticleNetwork } from "@particle-network/auth";
​
const pn = new ParticleNetwork({...});
// open buy
// To set target and features for custom window style, same as window.open().
pn.openBuy(options?: OpenBuyOptions, target?: string, features?: string)
​
You can customize the open buy page by setting
options parameters.name | description | type | required |
|---|---|---|---|
network | [Solana, Ethereum, Binance Smart Chain, Avalanche, Polygon] | string | False |
fiatCoin | Fiat currency | string | False |
cryptoCoin | crypto currency | string | False |
fiatAmt | The amount of fiat currency that the user wants to spend.It's just for Buy Crypto | number | False |
cryptAmt | The amount of crypto currency that the user wants to sell.It's just for Sell Crypto | number | False |
fixFiatCoin | Prevent user from changing fiat currency | bool | False |
fixCryptoCoin | Prevent user from changing fiat cryptocurrency | bool | False |
fixFiatAmt | Prevent user from changing amount of fiat currency | bool | False |
walletAddress | Wallet address for the predefined cryptocurrency | string | False |
If Particle not connected. network and walletAddress are requried.

//install particle rainbowkit extension.
yarn add @particle-network/rainbowkit-ext
Init Particle.
// replace config 'xxx'
new ParticleNetwork({
appId: 'xxx',
clientKey: 'xxx',
projectId: 'xxx',
});
Add Particle to RainbowKit wallet list.
// add particle in group Popular
const popularWallets = {

​WalletConnect is an open protocol to communicate securely between Wallets and Dapps (Web3 Apps). If you integration Particle Auth, you can connect with other Dapps with WalletConnect protocol.
Download SDK to your project via Yarn.
yarn add @particle-network/walletconnect @particle-network/auth
Init SDK.
import { particleWalletConnect, IWalletConnectSession, SwitchChainEvent } from '@particle-network/walletconnect';
​
particleWalletConnect.init(evmProvider);
particleWalletConnect.hub.on(SwitchChainEvent.request, (options) => {
//TODO: listen switch chain
//approve switch chain
particleWalletConnect.approveSwitchChain(options.session.peerId);
//or reject switch chain
particleWalletConnect.rejectSwitchChain(options.session.peerId);
})
Connect to Dapps.
// connect dapp with uri, you can get uri from qrcode or clipboard.
const connectDapps = async (uri: string) => {
particleWalletConnect.hub.once(SessionRequestEvent.request, (peerInfo) => {
//TODO: receive dapps session request. show confirm modal for user.
//approve dapps session request.
particleWalletConnect.approveSessionRequest(walletconnectData.peerInfo.peerId);
//or reject dapps session request.
particleWalletConnect.rejectSessionRequest(walletconnectData.peerInfo.peerId);
});
particleWalletConnect.hub.once(SessionRequestEvent.connected, (session: IWalletConnectSession) => {
//TODO: dapps connect success.
});
particleWalletConnect.hub.once(SessionRequestEvent.error, ({ session, error }: { session: IWalletConnectSession; error: Error }) => {
//TODO: dapps connect error.
});
await particleWalletConnect.newSession(uri);
};
Other APIs
// get all connected sessions
particleWalletConnect.getSessions();
​
//kill session
await particleWalletConnect.killSession(peerId);
​
// check uri is connected
particleWalletConnect.isSessionConnected(uri);
​
// check string is walletconnect uri
particleWalletConnect.isValidUri(txt);
​Particle Wallet has already supported this protocol, you can use it scan qrcode connect to Dapps.
Particle Auth support Solana official component wallet-adapter, you can quickly add Particle Auth to your DApp.
export const Wallet: FC = () => {
// The network can be set to 'devnet', 'testnet', or 'mainnet-beta'.
const network = WalletAdapterNetwork.Devnet;
​
// You can also provide a custom RPC endpoint.
const endpoint = useMemo(() => clusterApiUrl(network), [network]);
​
const wallets = useMemo(
() => [
/**
* Select the wallets you wish to support, by instantiating wallet adapters here.
*
* Common adapters can be found in the npm package `@solana/wallet-adapter-wallets`.
* That package supports tree shaking and lazy loading -- only the wallets you import
* will be compiled into your application, and only the dependencies of wallets that
* your users connect to will be loaded.
*/
