Thirdweb Account Abstraction on SEI

Overview

This guide provides a comprehensive, step-by-step tutorial for integrating thirdweb’s Account Abstraction SDK on Sei. By the end of this guide, you will understand how to create seamless wallet connectivity with social logins and build decentralized applications with sponsored gas transactions.

What This Guide Covers

  • Core concepts and benefits for user experience
  • Creating a React application with thirdweb SDK and Vite
  • Setting up social logins and gasless transactions
  • Interacting with smart contracts

Prerequisites

Before starting, ensure you have:

  • Node.js v18+ installed
  • Basic knowledge of React and TypeScript
  • A thirdweb account with API key from thirdweb Dashboard 
  • A deployed smart contract on SEI (we’ll use a simple Storage contract)
For Mainnet: An active thirdweb Pay As You Go subscription ($5/month minimum) is required for gas sponsorship on mainnet.

What is Account Abstraction?

Account Abstraction (AA) is a paradigm that transforms how users interact with blockchain applications. Instead of traditional externally-owned accounts (EOAs), users get smart contract wallets that enable advanced features.

Core Concepts

  • Smart Wallets: Contract-based accounts with programmable logic
  • Gas Sponsorship: Dapps pay transaction fees on behalf of users
  • Social Recovery: Alternative authentication methods beyond private keys
  • Batch Transactions: Multiple operations in a single transaction

Network Information

SEI Mainnet Configuration

  • Network Name: SEI EVM
  • Chain ID: 1329
  • Public RPC URL: https://evm-rpc.sei-apis.com
  • Explorer: https://seiscan.io/ 
  • Currency: SEI
  • thirdweb RPC: https://1329.rpc.thirdweb.com/{YOUR_CLIENT_ID}

Step 1: Deploy a Storage Contract

Before integrating the SDK, deploy a simple Storage contract on SEI. This contract will store and retrieve a number.

Storage Contract (Solidity)

Storage.sol
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;
 
contract Storage {
    uint256 private value;
 
    function store(uint256 num) public {
        value = num;
    }
 
    function retrieve() public view returns (uint256) {
        return value;
    }
}

Deploy this contract using Remix  on Sei. Note down the contract address - you’ll need it in the code.

Step 2: Project Setup

Create a New Project

npm create vite@latest sei-thirdweb-app -- --template react-ts
cd sei-thirdweb-app
npm install

Install Dependencies

npm install thirdweb@^5

Configure Environment Variables

Create a .env file in your project root:

.env
VITE_TEMPLATE_CLIENT_ID=your_thirdweb_client_id_here

Get your Client ID from thirdweb Dashboard  → Settings → API Keys.

Enable Gas Sponsorship

If you want to sponsor gas on mainnet:

  1. Go to thirdweb Dashboard Billing 
  2. Subscribe to the Pay As You Go plan ($5/month)
  3. Without this, sponsored transactions will fail on mainnet

Step 3: Configure thirdweb Client

Create src/client.ts:

src/client.ts
import { createThirdwebClient } from 'thirdweb';
 
export const client = createThirdwebClient({
  clientId: import.meta.env.VITE_TEMPLATE_CLIENT_ID
});

Step 4: Smart Contract Integration

Replace src/App.tsx:

src/App.tsx
import {
  ConnectButton,
  TransactionButton,
  useActiveAccount,
} from "thirdweb/react";
import { inAppWallet } from "thirdweb/wallets";
import { client } from "./client";
import { getContract } from "thirdweb";
import { defineChain } from "thirdweb/chains";
import { prepareContractCall, sendAndConfirmTransaction } from "thirdweb";
 
const THIRDWEB_API_KEY = import.meta.env.VITE_TEMPLATE_CLIENT_ID;
 
// Configure Sei network
const rpc = `https://1329.rpc.thirdweb.com/${THIRDWEB_API_KEY}`;
const seiChain = defineChain({
  id: 1329,
  rpc,
});
 
// Your deployed Storage contract address
const storageContract = getContract({
  client,
  chain: seiChain,
  address: "0xYourContractAddressHere", // Replace with your contract address
});
 
// Configure wallet options
const wallets = [
  inAppWallet({
    auth: {
      options: [
        "google",
        "x",
        "apple",
        "discord",
        "facebook",
        "farcaster",
        "telegram",
        "email",
        "phone",
        "passkey",
        "guest",
      ],
    },
  }),
];
 
// Store custom value function
async function handleStore(account: any, value: string) {
  if (!account) return;
 
  const transaction = prepareContractCall({
    contract: storageContract,
    method: "function store(uint256 num)",
    params: [BigInt(value)],
  });
 
  try {
    const txResult = await sendAndConfirmTransaction({
      transaction,
      account,
    });
    console.log("Transaction successful:", txResult.transactionHash);
    alert(`Stored ${value} successfully!`);
    return txResult.transactionHash;
  } catch (error) {
    console.error("Transaction failed:", error);
    alert("Transaction failed. Check console for details.");
  }
}
 
// Retrieve value function
async function handleRetrieve(account: any) {
  if (!account) return;
 
  const transaction = prepareContractCall({
    contract: storageContract,
    method: "function retrieve() view returns (uint256)",
  });
 
  try {
    const txResult = await sendAndConfirmTransaction({
      transaction,
      account,
    });
    console.log("Retrieved value:", txResult);
    return txResult.transactionHash;
  } catch (error) {
    console.error("Retrieve failed:", error);
    alert("Failed to retrieve value. Check console.");
  }
}
 
function App() {
  const account = useActiveAccount();
 
  return (

Understanding Key Components

ComponentDescription
ConnectButtonPre-built UI component for wallet connection
TransactionButtonSimplified transaction execution with loading states
useActiveAccountHook to get currently connected account
prepareContractCallPrepares transaction for contract interaction
inAppWalletSmart wallet with social login capabilities

Step 5: Package Configuration

Ensure your package.json includes:

package.json
{
  "name": "sei-thirdweb-app",
  "private": true,
  "version": "0.0.0",
  "scripts": {
    "dev": "vite",
    "build": "tsc && vite build",
    "preview": "vite preview"
  },
  "dependencies": {
    "react": "^18.3",
    "react-dom": "^18.3",
    "thirdweb": "^5"
  },
  "devDependencies": {
    "@types/react": "^18.2.56",
    "@types/react-dom": "^18.2.19",
    "@vitejs/plugin-react": "^4.2.1",
    "typescript": "^5.2.2",
    "vite": "^4"
  }
}

Step 6: Run the Application

Start Development Server

npm run dev

Test the Application

  1. Open your browser and navigate to http://localhost:5173
  2. Click “Connect to Sei Network”
  3. Choose your preferred login method (Google, email, etc.)
  4. A smart wallet is automatically created for you (no gas fees!)
  5. After connecting, you’ll see three interaction buttons
  6. Try storing number 37 or a custom number
  7. Retrieve the stored value - all transactions are gasless!
  8. Monitor the browser console for: - Transaction hashes - Error messages - Connection status - Smart contract interactions
Gas fees are automatically sponsored when using Account Abstraction, so users don’t need SEI tokens to interact with the contract.

Step 7: Done!

You’ve successfully integrated thirdweb’s Account Abstraction SDK with Sei! Users can now connect with social logins and interact with your contracts without needing to hold SEI tokens for gas.

What You’ve Accomplished

  • Created a React application with thirdweb SDK v5
  • Configured Account Abstraction for SEI network
  • Implemented social login authentication
  • Deployed gasless transaction capabilities
  • Built contract interaction interfaces
  • Learned error handling for web3 applications
