Ethereum developers have announced that EIP-3074 will be included in the upcoming hard fork upgrade, bringing this proposal into the spotlight. While many are still asking, “What is EIP-3074?”, the answer lies at the intersection of user experience, security, and scalability. At its core, EIP-3074 is a protocol enhancement designed to bridge the gap between traditional externally owned accounts (EOAs) and advanced smart contract wallets—without altering the core Ethereum Virtual Machine (EVM).
This upgrade introduces new capabilities for EOAs by enabling them to delegate transaction authority to smart contracts, unlocking features previously exclusive to account abstraction (AA) systems. Let’s explore what EIP-3074 entails, how it impacts users and developers, and why it's sparking both excitement and debate across the Ethereum ecosystem.
Understanding EIP-3074: Enhancing Externally Owned Accounts
EIP-3074 is best described as a short-term improvement aimed at modernizing the user experience for EOAs—the standard wallet types most Ethereum users interact with today (like MetaMask). By modifying the Ethereum protocol, EIP-3074 allows an EOA to designate a smart contract (referred to as a “caller”) to execute transactions on its behalf.
This simple yet powerful change unlocks three critical functionalities:
- Sponsored transactions – Third parties can pay gas fees for users, enabling gasless onboarding.
- Batched transactions – Multiple operations can be executed in a single transaction, reducing complexity.
- Delegated access – Users can grant temporary control over their account to trusted services or dApps.
These features were previously only available through smart contract wallets. As a result, dApp developers had to build dual logic paths: one for EOAs and another for smart accounts. With EIP-3074, this fragmentation begins to dissolve.

Key Benefits of EIP-3074
While EIP-3074 primarily enhances EOAs, it also creates positive ripple effects for smart contract accounts and the broader ecosystem.
1. Smoother Migration to Smart Contract Wallets
One of the biggest hurdles in adopting smart contract wallets has been the cumbersome process of migrating existing assets. Transferring tokens, NFTs, and managing gas across multiple steps can be expensive and technically daunting.
EIP-3074 simplifies this by allowing users to initiate a single batched and sponsored transaction that moves assets and sets up a new smart account—all in one go. This reduces friction and lowers the barrier to entry for mainstream adoption.
2. Unified Developer and User Experience
With EIP-3074, dApps no longer need to maintain separate workflows for EOAs and smart accounts. Developers can design a single, streamlined interface that supports advanced features like transaction batching and fee sponsorship universally.
This unification encourages broader implementation of account abstraction patterns, even before full native support arrives. It also pushes development standards forward, making features like session keys and multi-signature controls more accessible within existing frameworks.
3. Hybrid Account Models: The Best of Both Worlds
Perhaps one of the most innovative outcomes of EIP-3074 is the emergence of hybrid accounts. Users can now designate a smart contract as the caller for their EOA, effectively giving a smart wallet partial control over a traditional key-based account.
For example:
- A user keeps their private key secure but allows a smart contract to manage routine transactions.
- If needed, they can revoke access instantly using their private key—acting as a failsafe mechanism.
This model enables experimental use cases in custodial solutions, enterprise wallets, or gradual onboarding flows where users “test” smart wallet features before fully migrating.
Is EIP-3074 Good for Account Abstraction?
The rise of EIP-3074 has sparked an important discussion: Does it accelerate or delay full account abstraction (AA)?
Historically, ERC-4337 was seen as the first major step toward widespread AA adoption. It introduced a standard for bundling user operations outside of consensus layers, enabling key features like social recovery and paymasters—without requiring protocol changes. Major platforms like OKX, Coinbase, Trust Wallet, and MetaMask have since begun integrating ERC-4337 support, signaling strong industry momentum.
However, ERC-4337’s initial hype also led to inflated expectations. The path to native AA, such as through RIP-7560 on Layer 2 or future Layer 1 upgrades, is proving longer than anticipated. Interest in native AA remains low on many Layer 2 networks due to competing priorities and technical complexities.
In this context, EIP-3074 emerges as a pragmatic solution—enhancing EOAs while we wait for full AA infrastructure to mature.
Synergy, Not Competition
Importantly, EIP-3074 does not replace ERC-4337; instead, the two proposals complement each other. EIP-3074 improves the immediate user experience for EOAs, while ERC-4337 continues laying the groundwork for long-term account abstraction.
That said, there are valid concerns:
- By improving EOAs, EIP-3074 may reduce the urgency for users to switch to smart contract wallets.
- It doesn’t solve deeper issues like automated recovery or complex permissions—key advantages of true AA.
- Without EIP-5003, which would enable direct upgrades from EOAs to smart accounts, EIP-3074 lacks a clear migration path toward full abstraction.
Moreover, after the Prague/Electra hard fork, Ethereum’s focus will likely shift toward Verkle trees and stateless clients—potentially leaving little room for AA-related upgrades in the next two years. This makes the inclusion of complementary proposals like EIP-5003 even more critical.
The Road Ahead: Innovation with Caution
EIP-3074 introduces two new opcodes—AUTH and AUTHCALL—that allow ordinary addresses to behave like smart contracts during execution. This subtle but powerful shift could redefine how users interact with dApps, DeFi protocols, and NFT marketplaces.
Yet, with innovation comes risk:
- Security models must evolve to handle delegated control safely.
- Phishing attacks could exploit user confusion around “authorized callers.”
- Malicious contracts might trick users into granting persistent access.
Developers must implement robust safeguards, including clear UI indicators for authorization status and time-limited delegation windows.

Frequently Asked Questions (FAQ)
Q: What problem does EIP-3074 solve?
A: It improves the functionality of externally owned accounts (EOAs) by enabling sponsored transactions, batched operations, and delegated access—features previously limited to smart contract wallets.
Q: Does EIP-3074 replace ERC-4337?
A: No. EIP-3074 complements ERC-4337 by enhancing EOAs in the short term, while ERC-4337 continues advancing full account abstraction independently.
Q: Can EIP-3074 enable gasless transactions?
A: Yes. Through sponsored transactions, third parties (like dApps or relayers) can pay gas fees on behalf of users.
Q: Will EIP-3074 delay full account abstraction?
A: It may slow migration momentum by improving EOAs, but it doesn’t block progress. Inclusion of EIP-5003 would help ensure a smoother transition path.
Q: Are there security risks with EIP-3074?
