Get started with ERC-4337 ⚡

It’s been ~6 months since ERC-4337 went live on Ethereum Mainnet — but 99% of web3 developers still don’t know how to get started with account abstraction.

We all know that traditional wallets (such as MetaMask) are extremely limited — with challenges like security risks, lack of customization, and generally, a poor user experience & onboarding process.

Smart wallets, on the other hand, introduce advanced functionality that’s not possible with traditional wallets. They use account abstraction (ERC-4337) to enable powerful features such as:

• Auto-generated wallets: Create new non-custodial wallets for your users when they sign up for your app, website, or game automatically

• Wallet recoverability: Create recoverable wallets for users that don’t require private keys or seed phrases

• Transaction batching: Execute multiple transactions at once to create delightful user experiences, like shopping cart & checkout flows

• Multisig wallets: Create shared wallets for multiple people, with enhanced security & tiered permissions

• Custom transactions: Enable signless transactions, set spend limits, & cover users’ fees with gasless for the smoothest app UX

This all sounds great… but how do you even get started?

At thirdweb, we built smart wallet contracts that you can deploy & use today — with 3 sets of 'account factory' + 'account' contracts:

But how are they all different, and which one should I choose for my web3 app?

📚️ Guide: How to Create Batch Transactions with Smart Wallets (ERC-4337)

In this guide, learn how to use account abstraction (ERC-4337) to batch multiple transactions with smart wallets — unlocking powerful features like:

• NFT checkouts: Allow users to purchase multiple NFTs with a shopping cart & checkout flow — saving gas with one transaction

• Multi-step app flows: Deploy an NFT contract, mint an NFT, and transfer it to a user — all in a single click/transaction

• Customizable transactions: Create an array of transactions you want to execute all at once using the Transaction Builder
