In this beginner’s guide, we will delve into what ERC-4337 is, the idea of account abstraction, how it works, and the potential benefits it offers to Ethereum users.
What is the ERC-4337?
In 2023, Ethereum is simplifying the onboarding of user wallets with EIP-4337 and ERC-4337, which is crucial for Web3 adoption.
Did you know? EIP proposes technical changes, while ERC drives Ethereum’s development.
ERC-4337 introduces smart capabilities for user accounts via “account abstraction,” removing or enhancing elements like seed phrases. This upgrade enables smart contracts in wallets, turning them into versatile “smart accounts.” But what does account abstraction entail, and why is it beneficial for Ethereum at this juncture? Account abstraction implies the introduction of fresh ideas or capabilities to user accounts under ERC-4337. It can also refer to the removal or extraction of certain aspects from user accounts, such as reducing reliance on seed phrases, private keys, and individual transaction signing.
Smart accounts manage various tasks, from authentication to crypto subscriptions. ERC-4337 expands wallet capabilities, offering personalized user experiences. It’s like transforming your wallet into a multifunctional tool, seamlessly adapting to various payment methods. This analogy underscores how account abstraction in blockchain fosters user-centric smart accounts.
The journey of ERC-4337 began as EIP-4337, thus establishing a clear differentiation between the two. It’s important to note that ERC mainly focuses on defining standards for protocol specifications and development methodologies.
Essentially, ERC-4337 serves as an upgrade to the Ethereum ecosystem, enabling the integration of smart contract functionalities into wallets. In essence, it seeks to transform your wallets into “smart accounts.” But what exactly are “smart accounts,” and how can they be advantageous? Smart accounts can serve a multitude of functions, from managing multi-factor authentication to initiating and maintaining crypto subscriptions through code.

How Does ERC-4337 Work?
With ERC 4337’s implementation, the entire process becomes more automated and eliminates the need for private key dependencies and laborious user tasks, as illustrated below.
To dive deeper into the concept, ERC-4337 introduces a something called a UserOperation, which represents a pseudo-transaction that can be sent on behalf of a user. Unconfirmed UserOperation transactions are held in an alternative memory pool, referred to as the alt mempool.
Within the Ethereum network, nodes have the option to act as Bundlers. These Bundlers collect multiple UserOperations and combine them into a single transaction, known as a bundle transaction. These bundle transactions are then transmitted to a global smart contract known as the EntryPoint, which is unique on the Ethereum blockchain.
The Bundler initiates a function call on the EntryPoint smart contract called handleOps. In this function, the bundle transaction is received, and a specific function, validateUserOp, is executed for each account.
The primary purpose of the validateUserOp function is to verify the signature of the operation and, if the operation aligns with the account’s criteria, process the corresponding gas fee payment. Subsequently, each smart contract wallet must implement an additional function to execute the operation sent by the EntryPoint contract.

What are the benefits of Account abstraction?
There are a few benefits that the Ethereum ERC 4337 token standard brings to the table. Some of them are listed below:
- Seed Phrase Independence in ERC-4337
ERC-4337 offers more secure wallets free from seed phrase reliance, reducing vulnerabilities. It introduces user-friendly alternatives like two-factor authentication and biometrics to enhance adoption.
- Enhanced Precision with Smart Contract Wallets
By incorporating smart contract wallets, ERC-4337 reduces human error and bolsters network security through account abstraction, safeguarding against unauthorized fund access.
- Seamless Cross-Blockchain Compatibility
ERC-4337 simplifies adaptation across various blockchains, supporting Ethereum Virtual Machine-compatible networks like Polygon, Avalanche, and Arbitrum.
- Flexible Shared Accounts and Multi-User Operations
Unlike traditional EOA wallets, which offer full access control via a single seed phrase, account abstraction wallets allow multi-signature systems and controlled payments to specific wallet collections by multiple users within set timeframes.
How Will ERC-4337 Help Users?
ERC-4337 has the potential to revolutionize the complex user experience of crypto wallets, potentially driving higher adoption rates. Let’s explore some key aspects of what ERC-4337 could offer:
- Simplified Wallet Setup: With ERC-4337, there’s no need to laboriously record seed phrases. Wallet setup becomes a breeze, requiring just a few clicks for quick and easy activation.
- Stress-Free Account Recovery: Users can bid farewell to the anxiety of losing their seed phrases. The implementation of multi-factor authentication and account recovery mechanisms becomes feasible, eliminating the fear of being locked out of their accounts.
- User-Friendly Wallet Features: ERC-4337 empowers users with an array of customizable services, such as automated payments, pre-approved transactions, and bundled transactions. The possibilities become limitless for users, ensuring a highly personalized experience.
- Enhanced Security: There’s the potential for heightened wallet security as the likelihood of human errors diminishes. No longer will people resort to concealing their seed phrases under their mattresses. In theory, ERC-4337 promises a smoother and more user-friendly experience, removing a significant obstacle to widespread adoption.
- Gas Fee Versatility: Wallets leveraging ERC-4337 gain the ability to pay gas fees with a wide range of tokens, including ERC-20 tokens and more. Developers can create wallets that facilitate gas fee payments using various tokens, and even fiat currencies, offering greater flexibility in transaction processing.
In summary, ERC-4337 has the potential to streamline crypto wallet usage, making it more accessible and secure, thus eliminating a major barrier to mass adoption. This standard also introduces versatility in gas fee payments, further enhancing the user experience.
The history of Account abstraction wallets
The significance of ERC-4337 is clear when we review the history that had previously stated proposals for account abstraction.
- EIP-86, from 2016-17, aimed to empower smart contracts to initiate and approve transactions, but it required approval from account owners, creating friction.
- In 2020, EIP-2938 focused on creating a new top-level account using address-specific smart contract generation.
- EIP-3074, also in 2020, sought to make smart contract execution more efficient with a new opcode for self-executing smart contracts.
- EIP-196 aimed to enhance smart contract efficiency and security but faced rejection due to its need for changes in the Ethereum consensus layer.
In contrast, EIP-4337, proposed in 2021 and authorized in 2023, is notable for avoiding consensus-layer changes, addressing the challenges that actually hindered the previous account abstraction proposals.
