The Ethereum ecosystem continues to evolve at a rapid pace, with a strong focus on improving usability, security, and scalability. One of the most transformative developments currently shaping the future of Ethereum is Account Abstraction (AA)—a concept gaining momentum since 2023 and set to reach new heights with the upcoming Pectra upgrade in early 2025.
At the heart of this transformation are two pivotal Ethereum Improvement Proposals: EIP-3074 and EIP-7702. These upgrades aim to bridge the gap between traditional wallet functionality and the advanced capabilities of smart contracts, paving the way for a more intuitive and secure web3 experience.
This article dives deep into how EIP-3074 and EIP-7702 are redefining account control, enhancing transaction efficiency, and bringing Ethereum closer to full account abstraction—without compromising decentralization or security.
What Is the Pectra Upgrade?
The Pectra upgrade, scheduled for early 2025, marks the next major milestone in Ethereum's evolution. While it includes various technical enhancements—such as increasing validator stake limits and optimizing EVM performance—one of its most anticipated features is the integration of user-facing improvements through native support for account abstraction.
Key objectives of Pectra include:
- Enhancing wallet flexibility and user experience.
- Introducing new opcodes to enable smart contract interaction with externally owned accounts (EOAs).
- Laying the foundation for widespread adoption of account abstraction across dApps and wallets.
As web3 onboards millions of new users, reducing friction in blockchain interactions becomes critical. That’s where Account Abstraction comes in.
Understanding Account Abstraction
In Ethereum, there are two primary types of accounts:
- Externally Owned Accounts (EOAs): Controlled by private keys. These are the standard wallets most users interact with (e.g., MetaMask). They can send transactions but cannot execute logic.
- Smart Contract Accounts (SCAs): Programmable accounts that can automate actions based on predefined rules but cannot initiate transactions on their own.
Account Abstraction (AA) aims to merge the best of both worlds—allowing EOAs to benefit from smart contract functionality while maintaining familiar signing mechanisms.

This means users could perform complex operations like batched swaps, gasless transactions, or multi-factor recovery—without needing to manage multiple signatures or understand underlying blockchain mechanics.
Benefits of Account Abstraction
Account Abstraction unlocks several key advantages:
- User-Friendly Interactions: Simplifies blockchain usage for non-technical users.
- Enhanced Security: Reduces reliance on private key exposure through delegated execution.
- Advanced Transaction Logic: Enables conditional transactions, scheduled actions, and cross-chain operations.
- Gas Flexibility: Supports paying fees in ERC-20 tokens instead of ETH only.
- Recovery Mechanisms: Offers social recovery, time locks, and multi-signature fallbacks.
Despite these benefits, widespread adoption has been limited—primarily because most wallets remain EOAs, and native support for SCAs is still emerging.
The Road to Full Abstraction: ERC-4337 and Beyond
ERC-4337, introduced as a major step toward account abstraction, enables smart contract wallets without protocol changes. It allows features like:
- Paymasters that sponsor gas fees.
- Aggregated signatures via bundlers.
- Session keys and intent-based transactions.
However, ERC-4337 operates externally to the protocol—meaning it relies on off-chain infrastructure and isn't universally supported by dApps or wallets. Most users still rely on EOAs controlled by a single private key.
To address this, Ethereum developers are pushing for on-chain solutions—starting with EIP-3074.
What Is EIP-3074?
EIP-3074 introduces two new opcodes—AUTH and AUTHCALL—to the Ethereum Virtual Machine (EVM), enabling EOAs to securely delegate transaction execution to smart contracts.
This proposal effectively gives traditional wallets the power of smart contract accounts—without requiring users to migrate or deploy new contracts.
How EIP-3074 Works
- AUTH: A user signs a message authorizing a specific smart contract (called an invoker) to act on their behalf. The signature is verified using ECDSA.
- AUTHCALL: The authorized contract can now make calls from the user’s address, sending transactions, interacting with dApps, or executing multiple actions in sequence.
For example:
You want to swap DAI for ETH on Uniswap. Instead of signing two separate approvals and swaps, you sign once usingAUTH. The invoker contract then usesAUTHCALLto approve DAI spending and execute the swap—all in one flow.
This reduces friction, lowers gas costs via batching, and improves UX significantly.
Key Benefits of EIP-3074
🔐 Secure Delegation Without Key Exposure
Users retain full control over their private keys. The invoker never gains access to funds—only permission to execute specific transactions under defined conditions.
💸 Sponsored Transactions (Gasless UX)
Third parties (like dApps or protocols) can cover gas fees for users. The sponsor submits the transaction after the user signs it—enabling truly gasless onboarding experiences.
⚡ Batched Operations
Multiple transactions (e.g., approvals, swaps, staking) can be grouped into a single execution path. This saves time, reduces errors, and cuts gas costs by minimizing redundant computations.

Challenges with EIP-3074
Despite its promise, EIP-3074 comes with trade-offs:
- Risk of Malicious Invokers: If a user authorizes a malicious contract, it could drain funds during the active session.
- Nonce Dependency: Authorizations expire when the EOA sends any other transaction (due to nonce change), limiting long-term delegation.
- No Direct Ether Control: EOAs under
AUTHcannot directly send ETH; all value transfers must go throughAUTHCALL.
These limitations highlight the need for further refinement—enter EIP-7702.
Introducing EIP-7702: The Next Evolution
Proposed by Vitalik Buterin, EIP-7702 enhances EIP-3074 by allowing an EOA to temporarily become a smart contract for a single transaction.
It introduces a new transaction type containing:
contract_code: Temporary logic injected into the EOA.signature: ECDSA proof authorizing the code execution.
After execution, the EOA reverts to its original state—making the upgrade both powerful and safe.
Example Use Case
Imagine swapping tokens and staking the output in one atomic operation:
- Your EOA includes contract code that performs a swap and deposits into a staking pool.
- You sign the transaction.
- The network executes the logic as if your wallet were a smart contract—then returns it to normal.
No permanent delegation. No risk of lingering permissions.
Advantages of EIP-7702 Over EIP-3074
| Feature | EIP-3074 | EIP-7702 |
|---|---|---|
| Execution Model | Delegates to external invoker | Turns EOA into temporary SCA |
| Trust Requirements | Requires trusted invoker | Trustless; no intermediary needed |
| Security Risk | Higher (malicious invoker) | Lower (self-contained execution) |
| Flexibility | Limited by invoker logic | Fully programmable per transaction |
EIP-7702 eliminates dependency on third-party invokers, making transactions more secure and composable.
FAQ: Account Abstraction & Upcoming Upgrades
Q: What is Account Abstraction in simple terms?
A: It’s a way to make crypto wallets smarter—letting them do things like batch transactions, recover accounts, or pay gas in any token—just like apps do.
Q: Will EIP-3074 replace MetaMask?
A: Not replace—but enhance. MetaMask and similar wallets can integrate EIP-3074 to offer smart contract features without changing how users sign messages.
Q: Is EIP-7702 safer than EIP-3074?
A: Yes. Because it avoids permanent delegation and removes reliance on external contracts, EIP-7702 reduces attack surfaces and offers trustless execution.
Q: When will these upgrades go live?
A: Both are expected in the Pectra hard fork, targeting early 2025. Final inclusion depends on testing and consensus among core developers.
Q: Do I need to migrate my wallet?
A: No. These upgrades work with existing EOAs. You’ll gain enhanced features automatically through compatible wallets and dApps.
Q: Can I use any token to pay gas after Pectra?
A: With paymaster integrations enabled by AA, yes—many dApps will allow gas payment in popular ERC-20 tokens like USDC or DAI.
The Bigger Picture: A Smoother Web3 Future
Together, EIP-3074 and EIP-7702 represent a strategic move toward seamless account abstraction. They lower barriers for mainstream adoption by:
- Removing technical complexity.
- Enabling gasless onboarding.
