Sign Transactions

Arcana wallet is an embedded Web3 wallet available to all the dApps that integrate with the Arcana Auth SDK..

In this guide, you will learn how a dApp can add functionality to allow users to sign blockchain transactions by using the JSON RPC calls supported by Arcana wallet.


Register and configure your application using the Arcana Developer Dashboard. Next, install the @arcana/auth package. Integrate the Auth SDK with your dApp. For details, see Arcana Auth Quick Start Guide.

const { AuthProvider } = window.arcana.auth // From CDN
import { AuthProvider, CHAIN } from '@arcana/auth' //From npm
//clientId : Arcana Unique App Identifier via Dashboard
const clientId = 'xar_test_445007f942f9Ba718953094BbeeeeeB9484cAfd2'
const auth = new AuthProvider(`${clientId}`, { //required
  network: 'testnet', //defaults to 'testnet'
  position: 'left', //defaults to right
  theme: 'light', //defaults to dark
  alwaysVisible: false, //defaults to true, wallet always visible
  chainConfig: {
    rpcUrl: '', //defaults to ''
try {
  await auth.init()
} catch (e) {
  // Handle exception case

Make sure you have already initialized the wallet before invoking any JSON RPC call to sign a transaction using Arcana wallet.

// Assuming Auth SDK is integrated and initialized
try {
  provider = auth.provider
  const connected = await auth.isLoggedIn()
  console.log({ connected })
} catch (e) {
  // Handle exception case

// setHooks: Manage chain or account switch in Arcana wallet
function setHooks() {
  provider.on('connect', async (params) => {
    console.log({ type: 'connect', params: params })
    const isLoggedIn = await auth.isLoggedIn()
    console.log({ isLoggedIn })
  provider.on('accountsChanged', (params) => {
    console.log({ type: 'accountsChanged', params: params })
  provider.on('chainChanged', async (params) => {
    console.log({ type: 'chainChanged', params: params })

Sign Transaction

async function signTransaction() {

  const { sig } = await provider.request({
    method: 'eth_signTransaction',
    params: [
        from, // sender account address
        gasPrice: 0,
        to: '0xE28F01Cf69f27Ee17e552bFDFB7ff301ca07e780', // receiver account address
        value: '0x0de0b6b3a7640000',
  console.log({ sig })

The following figure shows how Arcana wallet displays the details of a blockchain sign transaction and asks the user to approve or reject it:

That is all! You are all set to allow dApp users to sign blockchain transactions.
