The blockchain space is evolving rapidly, and user experience is now a key focus. Tools like Account Abstraction (AA) and Web3Auth are game-changers, offering powerful solutions for improving usability, security, and accessibility in decentralized applications (dApps). By integrating these tools with the XDC Network, developers can unlock unparalleled potential for creating seamless, Web2-like user experiences.
This article will guide you through understanding AA and Web3Auth, their benefits, real-world use cases, and how to leverage them with the XDC Network.
What is Account Abstraction(AA)?
Account Abstraction (AA) is a game-changing mechanism that decouples account logic from the underlying blockchain protocol. Traditionally, blockchain accounts are categorized as:
- Externally Owned Accounts (EOAs): Controlled by private keys.
- Contract Accounts (CAs): Governed by smart contract code.
With AA, the distinction between EOAs and CAs blurs, allowing users to design custom account behavior. This opens up a world of possibilities for developers and end users alike.
Key Features of Account Abstraction:
- Customizable Logic: Define how transactions are signed and executed with programmable rules.
- Enhanced Security: Implement advanced features like multi-factor authentication, spending limits, and time-based restrictions.
- Improved Usability: Support gas sponsorships, enabling users to pay transaction fees in tokens rather than native cryptocurrencies.
What is Web3 Auth?
Web3 Auth bridges traditional Web2 authentication methods with Web3’s decentralized ecosystem. By integrating user-friendly login options, it simplifies the onboarding process for new dApp users.
Benefits of Web3 Auth:
- Ease of Use: Familiar login methods, such as Google, Facebook, or email, reduce barriers for new users.
- Interoperability: Functions seamlessly across multiple blockchains and wallets.
- Security: Combines Web2 simplicity with Web3’s robust security protocols.
Why Integrate AA and Web3Auth with XDC Network?
The XDC Network is a robust enterprise-grade blockchain designed for real-world applications. It combines high performance with low costs, making it an ideal choice for developers aiming to build scalable, user-friendly dApps.
Key Advantages of the XDC Network
- EVM Compatibility: Enables seamless integration with Ethereum-based tools and applications.
- Low Transaction Costs: Transactions cost almost nothing, ideal for high-frequency dApps.
- Global Reach: Designed for real-time, cross-border settlements with minimal latency.
- Sustainability: XDC uses an energy-efficient XDPoS (Delegated Proof of Stake) consensus mechanism.
Integrating AA and Web3Auth with XDC Network allows developers to deliver sophisticated yet user-friendly experiences, catering to both Web2 and Web3 users.
Real-World Use Cases
1. Decentralized Finance (DeFi)
Leverage AA to implement enhanced security and allow gasless transactions. Use Web3Auth to simplify wallet access for non-technical users.
2. Gaming dApps
Enable gas-free in-game transactions using AA. Web3Auth can streamline onboarding by letting players log in with familiar credentials.
3. E-commerce
AA supports token-based payments with features like transaction batching and custom spending rules. Web3Auth ensures a smooth, secure user login experience.

How to Get Started
1. Understand AA and Web3Auth Fundamentals
Before diving into development, explore how AA and Web3Auth work. Focus on their core features and benefits.
2. Set Up Your Development Environment
Utilize the XDC Network's developer tools, including Etherspot’s SDK, to get started.
3. Build and Test Your dApp
Experiment with AA features like gas sponsorships and transaction batching. Use Web3Auth to implement user-friendly authentication.
4. Explore Etherspot’s Developer Guide
Access the comprehensive guide to learn how to implement AA on the XDC Network efficiently.
(As per the above guide link) To implement powerful Account Abstraction features into your dApp, follow these steps:
1. Install the packages
Note: You should have installed Node.js (version 18.10.0 or higher).
Install Etherspot Modular SDK with this command
npm i @etherspot/modular-sdk --save
2. Import the SDK
import { ModularSdk } from '@etherspot/modular-sdk';
3. Get the smart contract address
If you’re unsure about the difference between key-based accounts and smart contract accounts, please take a look at this page.
In this example, we simply create a key-based wallet with ethers.js like so:
const randomWallet = ethers.Wallet.createRandom();
const privateKey = randomWallet.privateKey;
Set the privayeKey in the .env : WALLET_PRIVATE_KEY
set the apiKey in .env: API_KEY
Then we use this key-based wallet to instantiate the SDK on XDC Network and get the wallet address.
const chainId = 50;
const modularSdk = new ModularSdk({ privateKey: process.env.WALLET_PRIVATE_KEY },
{ chainId: chainId,
bundlerProvider: new EtherspotBundler(chainId,
bundlerApiKey, customBundlerUrl) })
const address: string = await primeSdk.getCounterFactualAddress();
console.log(address);
4.Send funds to another address
Getting all together into a function
import { EtherspotBundler, ModularSdk, MODULE_TYPE, printOp, sleep } from '@etherspot/modular-sdk';
import * as dotenv from 'dotenv';
const recipient = ''; // recipient wallet address
const value = '0.0000001'; // transfer value
const bundlerApiKey = process.env.API_KEY;
const privateKey = process.env.WALLET_PRIVATE_KEY;
// initializating sdk...
const modularSdk = new ModularSdk({ privateKey: process.env.WALLET_PRIVATE_KEY },
{ chainId: Number(process.env.CHAIN_ID),
bundlerProvider: new EtherspotBundler(Number(process.env.CHAIN_ID), bundlerApiKey) })
console.log('address: ', modularSdk.state.EOAAddress)
// get address of EtherspotWallet...
const address: string = await modularSdk.getCounterFactualAddress();
console.log('\x1b[33m%s\x1b[0m', `EtherspotWallet address: ${address}`);
// clear the transaction batch
await modularSdk.clearUserOpsFromBatch();
// add transactions to the batch
const transactionBatch = await modularSdk.addUserOpsToBatch({ to: recipient, value: ethers.utils.parseEther(value) });
console.log('transactions: ', transactionBatch);
// get balance of the account address
const balance = await modularSdk.getNativeBalance();
console.log('balances: ', balance);
// estimate transactions added to the batch and get the fee data for the UserOp
const op = await modularSdk.estimate();
console.log(`Estimate UserOp: ${await printOp(op)}`);
// sign the UserOp and sending to the bundler...
const uoHash = await modularSdk.send(op);
console.log(`UserOpHash: ${uoHash}`);
// get transaction hash...
console.log('Waiting for transaction...');
let userOpsReceipt = null;
const timeout = Date.now() + 60000; // 1 minute timeout
while ((userOpsReceipt == null) && (Date.now() < timeout)) {
await sleep(2);
userOpsReceipt = await modularSdk.getUserOpReceipt(uoHash);
}
console.log('\x1b[33m%s\x1b[0m', `Transaction Receipt: `, userOpsReceipt);
