Native Account Abstraction vs ERC-4337: Account Abstraction Explained

We have already discussed about what account abstraction is. Account abstraction completely changes how blockchain wallets work by removing the limitations of traditional wallets.

While all account abstraction models turn wallets into programmable smart accounts, they are not all built the same. Two of the main approaches in account abstraction are: ERC-4337 and native account abstraction. Let's talk about these models and understand the exact difference in architecture which is important for the future of blockchain wallets:

What Is ERC-4337?

To understand ERC-4337, we first need to understand the problem with how Ethereum wallets traditionally work.

On EVM-compatible blockchains, most wallets today are called Externally Owned Accounts (EOAs). These wallets are controlled entirely by a single private key. If you lose the key, you lose access to your funds. If someone steals it, they control your wallet. There is no built-in recovery system, spending controls, biometric login, or flexible security model.

This system worked in the early days of crypto, but it creates major usability and security problems for mainstream adoption. Most users are not comfortable managing seed phrases, handling gas fees manually, or relying on a single key for everything.

This is where account abstraction comes in.

Account abstraction turns blockchain wallets into programmable smart accounts instead of rigid single-key wallets. Instead of transactions being approved only by one private key, the wallet can define custom rules for how transactions are validated and executed. This opens the door for features like:

• Biometric authentication
• Social recovery
• Gas fee sponsorship
• Multi-signature approvals
• Spending limits
• MPC security models

ERC-4337 is Ethereum’s way of introducing account abstraction without changing Ethereum’s core protocol.

Instead of modifying the blockchain itself, ERC-4337 adds a parallel infrastructure layer on top of Ethereum. This layer introduces several new components that work together to simulate smart account behavior.

To make this work without modifying Ethereum itself, ERC-4337 introduces several intermediary components. Here is how the ERC-4337 transaction flow works:

1. The user creates a UserOperation instead of a normal transaction: A UserOperation is a special instruction object that contains transaction details, validation logic, and gas-related information.
2. The UserOperation is sent to a separate mempool: Unlike normal Ethereum transactions, these operations are stored in a dedicated account abstraction mempool.
3. Bundlers collect UserOperations: A bundler is a network participant responsible for gathering multiple UserOperations and packaging them into a single blockchain transaction.
4. The bundled transaction is sent to the EntryPoint contract: The EntryPoint is a central smart contract that acts as the execution manager for ERC-4337 transactions. It verifies UserOperations and communicates with smart accounts.
5. Paymasters can sponsor gas fees: A paymaster is a smart contract that can pay gas fees on behalf of users, allowing applications to sponsor transactions so users do not need native ETH to get started.

This architecture allows account abstraction to work on existing Ethereum-compatible chains without requiring a hard fork or protocol redesign.

However, ERC-4337 still depends on additional infrastructure layers to function properly. Bundlers, paymasters, relayers, and EntryPoint contracts all add extra complexity to the transaction flow. Since the system operates as an overlay on top of EOAs rather than being integrated directly into the blockchain itself, scalability and efficiency can still be limited by the added infrastructure overhead.

What Is Native Account Abstraction?

Native account abstraction takes a completely different approach. Instead of adding account abstraction as an external framework on top of the blockchain, native account abstraction builds it directly into the blockchain protocol itself. In this model, smart accounts are treated as a core part of the network architecture from the very beginning.

This means the blockchain natively understands programmable accounts without relying on external transaction routing systems or intermediary smart contracts.

The transaction flow becomes much simpler:

1. The user initiates a transaction from a smart account: The account itself already contains programmable validation logic at the protocol level.
2. The blockchain directly validates the account rules: Instead of routing transactions through EntryPoint contracts or bundlers, the network itself processes validation natively.
3. Gas abstraction and authentication are handled directly within the protocol: Features like sponsored transactions, biometric authentication, passkeys, or MPC signing can be integrated much more efficiently because the blockchain is designed to support them from the start.
4. The transaction executes directly on-chain: Fewer external layers are involved, creating a cleaner, more streamlined process.

Because native account abstraction is embedded into the blockchain architecture itself, it removes much of the infrastructure complexity found in ERC-4337 systems. There is no dependency on separate bundler ecosystems or overlay transaction frameworks to make smart accounts function.

This approach also creates a stronger foundation for long-term scalability, advanced wallet security, and mainstream Web3 usability. Features such as biometric verification, gas sponsorship, social recovery, post-quantum security, and MPC wallet systems can integrate more naturally into the blockchain environment instead of being retrofitted onto legacy wallet models.

The Difference Between ERC-4337 and Native Account Abstraction at a Glance

While both models aim to improve blockchain wallet usability, security, and flexibility, the way they are implemented creates major differences in scalability, infrastructure complexity, and long-term user experience.

Where ARMchain Fits In

ARMchain is already among the very few blockchain projects that are being built with account abstraction embedded at the protocol level. This means that our quantum safe blockchain treats account abstraction as a foundational architecture layer rather than an external upgrade.

This allows users to interact with blockchain applications more securely and seamlessly without relying on a traditional EOA wallet structure. With native account abstraction and MPC-based security, users can effectively eliminate the limitations of single private key wallets, which is highly important for the future of blockchain adoption.

Not only this, ARMchain is specifically designed to support next-generation blockchain infrastructure where security, usability, and scalability work together instead of against each other. By integrating account abstraction directly into the protocol layer, ARMchain creates a more efficient environment for both enterprise-grade applications and mainstream users entering Web3 for the first time, offering: 

1. Native biometric authentication support
2. Built-in gas abstraction and sponsored transactions
3. Post-quantum cryptographic readiness for future-proof security

Final Words

As blockchain technology continues evolving toward mainstream adoption, account abstraction is becoming one of the most important infrastructure upgrades in Web3. While ERC-4337 introduced a major step forward by making smart accounts possible on existing Ethereum-compatible networks, native account abstraction pushes the concept even further by embedding it directly into the blockchain architecture itself.

This shift is helping create blockchain ecosystems that are more secure, scalable, and user-friendly for both enterprises and everyday users. By adopting native account abstraction at protocol level, ARMchain is positioning itself among the next generation of blockchain networks focused on long-term usability, advanced wallet security, and future-ready infrastructure.
