Ethereum wallets today are more limited than they might appear. While they serve their purpose, the current design stems from early blockchain paradigms that prioritized simplicity over flexibility. As the ecosystem evolves, so too must the tools users rely on to interact with it. Two groundbreaking proposals—EIP-3074 and ERC-4337—are poised to redefine how we think about digital ownership, security, and user experience in Ethereum.
This article explores the present limitations of Ethereum wallets, the innovations introduced by these proposals, and how they pave the way for a future where account abstraction becomes standard—ushering in a new era of usability, security, and accessibility.
Understanding Accounts, Wallets, and Abstraction
In today’s Ethereum network, there are two types of accounts: Externally Owned Accounts (EOAs) and Smart Contract Accounts.
- EOAs are controlled by private keys and are the most common form of wallet used today.
- Smart contract accounts, on the other hand, are governed by code and can execute complex logic autonomously.
All transactions on Ethereum currently originate from EOAs. These can interact with smart contracts, but only EOAs can initiate a transaction—and crucially, they must pay gas fees in ETH to do so.
A wallet is any system designed to manage user funds. While EOAs dominate, specially crafted smart contracts can also function as wallets—known as smart contract wallets. These offer advanced features beyond basic key-based control.
The concept of account abstraction aims to eliminate the distinction between EOAs and smart contract accounts. It allows all accounts to behave uniformly under the protocol, enabling enhanced functionality without special handling. This shift promises to solve long-standing usability issues and open doors to next-generation wallet experiences.

Limitations of Current Wallets
Despite their widespread use, EOAs come with significant drawbacks:
1. Private Key Management
Losing your private key means losing access to your assets—permanently. There’s no recovery option, making secure storage both critical and stressful for users.
2. Reliance on ECDSA Signatures
The Elliptic Curve Digital Signature Algorithm (ECDSA) has served Ethereum well, but it's not future-proof. Advances in quantum computing could eventually compromise its security.
3. Single-Operation Transactions
Each action requires a separate transaction, increasing costs and reducing efficiency. Batched operations aren’t natively supported.
4. ETH-Only Gas Payments
Users must hold ETH to pay gas fees—even if their primary assets are ERC-20 tokens. This creates friction for new users who may not know how to acquire ETH.
These pain points have driven demand for smarter, more flexible alternatives.
The Rise of Smart Contract Wallets
Smart contract wallets like Argent, Gnosis Safe, and Loopring already offer superior functionality compared to traditional EOAs. They enable features such as:
- Social recovery: Users designate trusted contacts or devices to help recover access—eliminating reliance on seed phrases.
- Multi-signature approvals: Require multiple parties to authorize transactions, enhancing security.
- Batched operations: Execute multiple actions in one transaction, saving gas and ensuring atomic execution.
- Custom validation logic: Support alternative signature schemes (e.g., BLS or Schnorr) that are simpler or quantum-resistant.
However, because Ethereum only allows EOAs to initiate transactions, these wallets rely on relayer services. A relayer takes a signed message from the user, wraps it into a standard EOA transaction, pays the gas, and submits it to the network. Some systems even allow gas payment in ERC-20 tokens via built-in fee abstraction mechanisms.
While functional, this approach lacks standardization. Each project must build its own infrastructure—increasing complexity and audit risk.
EIP-3074: Supercharging EOAs
One path toward account abstraction is enhancing existing EOAs rather than replacing them. Enter EIP-3074, proposed by Sam Wilson, Matt Garnett, and others.
This proposal introduces two new EVM opcodes:
AUTH: Authenticates a user’s signed intent.AUTHCALL: Allows a designated smart contract (called a signer or invoker) to act on behalf of the user.
Here’s how it works:
- A user signs a message with their private key.
- A smart contract (the invoker) submits a transaction containing this signature.
- Using
AUTH, the contract gains temporary control over the user’s EOA. - With
AUTHCALL, it executes transactions on the user’s behalf—without requiring the user to hold ETH.
This enables gas sponsorship, batched transactions, and even signature aggregation—all without migrating funds.
Crucially, EIP-3074 is backward-compatible. Users don’t need to move assets; they can opt in at any time.
But critics raise concerns: giving a contract full control over an EOA—even temporarily—carries risks reminiscent of past exploits like the DAO hack.

ERC-4337: Full Account Abstraction Without Forks
An alternative—and increasingly popular—approach is ERC-4337, championed by Vitalik Buterin and others.
Unlike EIP-3074, ERC-4337 doesn’t require a hard fork. Instead, it implements account abstraction at the application layer through a system called UserOperations.
Here’s the flow:
- Users submit a
UserOperationobject describing their desired action. - Bundlers collect these operations and package them into a single transaction.
- This bundle is sent to an EntryPoint contract, which validates and processes each operation.
- The EntryPoint triggers the user’s smart contract wallet, which executes the logic securely.
Because everything happens through smart contracts, users gain full programmability:
- Pay gas in any ERC-20 token.
- Use biometric or social login methods.
- Set up time locks or spending limits.
- Enable seamless recovery mechanisms.
ERC-4337 is already live on testnets like Goerli and supported by clients such as Nethermind and Go-Ethereum. Wallets like MetaMask are actively working on integration.
Comparing the Two Paths
| Feature | EIP-3074 | ERC-4337 |
|---|---|---|
| Requires Hard Fork | Yes | No |
| Backward Compatible | Yes | Requires migration |
| Native Gas Abstraction | Limited | Full support |
| Flexibility | Moderate | High |
| Security Risk | Higher (contract control) | Lower (sandboxed execution) |
While EIP-3074 offers a quick upgrade path for existing users, ERC-4337 represents a more sustainable long-term vision—one where all accounts are smart contract-based by default.
The Road Ahead: Toward Full Abstraction
The long-term goal is clear: eliminate EOAs entirely and replace them with upgradable smart contract wallets. This would make advanced features like social recovery and multi-sig standard—not optional extras.
ERC-4337 supporters envision a future where:
- The
UserOperationmempool replaces the traditional transaction pool. - A hard fork converts all EOAs into smart contract wallets.
- Systems like Optimism’s “account abstraction” upgrades become mainstream.
In contrast, EIP-3074 may create technical debt in a post-abstraction world. Its reliance on EOA-level permissions doesn’t align neatly with fully abstracted accounts.
Still, both proposals reflect years of experimentation and progress. They’re not mutually exclusive—many see them as complementary steps toward broader adoption.
