Tutorial: Rethinking dApp Onboarding with Account Abstraction

Source: Dev.to

Problem: The EOA (Externally Owned Account) Limitation

• On traditional EVM chains, a user’s account is just a keypair.
• It can’t initiate transactions on its own.
• It can’t batch transactions (e.g., approve + swap).
• Recovery is impossible if the key is lost.

The Abstract Chain Solution: Every Account is a Smart Contract

Gasless Transactions for Users

You could sponsor your users’ first few transactions. The protocol allows a paymaster to cover the gas fee, removing a major onboarding hurdle.

Secure, Social Recovery

Instead of forcing users to save a seed phrase, you can integrate a social recovery module.

// Hypothetical SDK for Abstract Chain
import { AbstractWallet } from '@abstract-chain/sdk';

// Onboarding a new user
async function createRecoverableWallet(userEmail, guardian1_address, guardian2_address) {
    const newWallet = await AbstractWallet.create({
        owner: userEmail, // User can log in via familiar methods
        recoveryMechanisms: [
            { type: 'social', guardians: [guardian1_address, guardian2_address], threshold: 2 }
        ]
    });
    console.log(`New smart account created at: ${newWallet.address}`);
}

Transaction Batching

Let users approve a token and swap it in a single, atomic transaction. This drastically improves UX for DeFi applications.
