Ethereum has long been the foundation for decentralized innovation, powering smart contracts, DeFi protocols, and next-generation dApps. As the ecosystem evolves, scalability, usability, and security remain top priorities. One of the most anticipated upgrades in this journey is EIP-3074, a proposal designed to streamline transaction workflows while enhancing user control and security.
Although not yet live on Ethereum’s mainnet as of mid-2025, EIP-3074 is expected to be implemented as part of the broader Pectra upgrade by the end of the year. This upgrade introduces two powerful new opcodes—AUTH and AUTHCALL—that fundamentally change how transactions are authorized and executed on the network.
These changes aim to bridge the gap between traditional account-based transactions and more flexible, contract-driven interactions—making Ethereum more accessible to both developers and everyday users.

Understanding AUTH: Separating Authorization from Execution
Currently, every Ethereum transaction requires the sender to both sign and broadcast it. This means your private key must be used each time you interact with the network—whether swapping tokens, voting in governance, or minting NFTs.
EIP-3074 introduces the AUTH opcode, which decouples who authorizes a transaction from who sends it. In simple terms, you can sign a message authorizing someone—or something—to submit a transaction on your behalf, without giving them access to your wallet.
Think of it like issuing a signed check: you authorize a specific amount to be spent, but another party deposits it. Similarly, with AUTH, you create a signed authorization that designates an “executor” address. That executor can then submit the transaction to the network, but only within the scope of what you’ve approved.
This model enhances flexibility in multi-user setups—such as DAOs or shared wallets—where one member may draft a proposal while another executes it after consensus. It also opens the door to gasless transactions, where third parties (like dApp operators) pay gas fees on users’ behalf, improving onboarding for newcomers unfamiliar with ETH gas mechanics.
Exploring AUTHCALL: Smart Contracts Acting on Your Behalf
While AUTH handles authorization, AUTHCALL enables execution. Once an address is authenticated via AUTH, AUTHCALL allows a smart contract to perform actions as if it were the user. This is a game-changer for automation and user experience.
Imagine having a personal finance bot that automatically pays your monthly subscriptions or rebalances your DeFi portfolio. With EIP-3074, this bot (a smart contract) could execute these transactions under your identity—without needing repeated manual approvals.
More importantly, because AUTHCALL operates within the context of your externally owned account (EOA), the transaction appears indistinguishable from one you signed directly. This preserves compatibility with existing protocols that don’t support account abstraction (like ERC-4337), while delivering similar benefits.
Developers can leverage this to build:
- Auto-repay mechanisms for lending platforms
- Subscription-based services with recurring payments
- Cross-protocol arbitrage bots triggered by user-defined conditions

Key Benefits of EIP-3074
1. Enhanced Security Through Controlled Delegation
By allowing limited delegation of transaction rights, EIP-3074 reduces exposure of private keys. Instead of signing every action, users sign once for a set of predefined operations—lowering the risk of phishing attacks or key compromise.
2. Improved User Experience
Removing friction from repeated signing improves UX dramatically. First-time users won’t need to understand gas fees upfront; experienced traders can automate complex strategies without relying on custodial solutions.
3. Support for Advanced DeFi Innovations
With secure delegation and contract-powered execution, DeFi protocols can introduce features like:
- Batched limit orders
- Conditional swaps based on price triggers
- Self-executing loan liquidations
These capabilities position Ethereum to compete with centralized platforms on functionality while maintaining decentralization.
4. Gasless Transactions and Sponsored Operations
DApps can sponsor gas fees for users by acting as executors. This enables truly gasless onboarding—users sign authorization messages off-chain, and the dApp submits transactions on their behalf using AUTH + AUTHCALL.
This is especially valuable for gaming, social apps, and emerging markets where ease-of-use drives adoption.
Addressing Risks and Challenges
Despite its promise, EIP-3074 introduces new trust considerations. Granting another entity the ability to act on your behalf carries inherent risks if misused.
For example:
- Could an executor front-run your transactions?
- What happens if the authorized contract contains malicious logic?
To mitigate these concerns, the Ethereum community is exploring safeguards such as:
- Time-bound authorizations
- Action-specific permissions (e.g., spend limits)
- Transparent audit requirements for executor contracts
Additionally, EIP-3074 works best when combined with other upgrades like EIP-1559 (predictable fee markets) and EIP-2930 (access lists), which reduce execution variability and optimize performance.
The Bigger Picture: Ethereum's Usability Evolution
EIP-3074 isn't an isolated change—it's part of a broader push toward account abstraction lite, making Ethereum more programmable and user-friendly without requiring full-scale architectural shifts.
Together with initiatives like ERC-4337 and future protocol upgrades, EIP-3074 helps lay the groundwork for a world where:
- Wallets become intelligent agents
- Transactions are seamless and intuitive
- Users retain full control without technical overhead
As adoption grows, simplifying interaction layers will be just as important as scaling throughput.

Frequently Asked Questions (FAQ)
Q: When will EIP-3074 go live on Ethereum mainnet?
A: As of 2025, EIP-3074 is scheduled for activation during the Pectra upgrade, expected by the end of the year. Final timelines depend on testing outcomes and network consensus.
Q: Does EIP-3074 require wallet updates?
A: Yes, wallets will need to support the new AUTH and AUTHCALL opcodes. Major providers like MetaMask and hardware wallets are already preparing for compatibility.
Q: Can I revoke an authorization after using AUTH?
A: While revocation isn’t built into EIP-3074 directly, developers can design time-limited or single-use authorizations. Future extensions may include native revocation mechanisms.
Q: Is EIP-3074 replacing account abstraction?
A: No—it complements it. EIP-3074 offers a simpler path to some account abstraction benefits without requiring full ERC-4337 adoption.
Q: Will EIP-3074 make Ethereum faster?
A: Not directly. It doesn’t increase block speed or throughput but improves transaction efficiency and reduces user burden.
Q: Can malicious actors exploit AUTHCALL?
A: Only if users authorize unsafe contracts. As with all DeFi interactions, due diligence is essential. Limiting permissions and using audited executors minimizes risk.
Conclusion
EIP-3074 represents a pivotal step forward in Ethereum’s mission to become more usable, secure, and developer-friendly. By introducing AUTH and AUTHCALL, it enables powerful new patterns—like gasless transactions, automated payments, and advanced DeFi logic—without sacrificing decentralization.
As part of the upcoming Pectra upgrade, this EIP could significantly lower barriers to entry while unlocking new possibilities for innovation across dApps, wallets, and financial protocols.
For developers, it’s an opportunity to rethink user flows. For users, it’s a path toward smoother, smarter interactions with Web3.
The future of Ethereum isn’t just about scaling—it’s about simplifying. And EIP-3074 is leading that charge.
