EIP-3074 is an Ethereum Improvement Proposal designed to streamline transactions while enhancing security on the Ethereum network. By introducing two groundbreaking operations—AUTH and AUTHCALL—it decouples transaction authorization from execution, offering new flexibility for users and developers alike. As of August 2024, EIP-3074 is slated for deployment with the Pectra upgrade by late 2024.
How EIP-3074 Works
The AUTH Operation
AUTH enables delegation of transaction authority. Traditionally, the sender and authorizer of a transaction are the same entity. With AUTH, users can authorize another Ethereum address to initiate transactions on their behalf—similar to granting a trusted proxy limited spending rights.
Key features:
- Delegated control: Authorize third-party addresses (e.g., smart contracts or trusted agents) to act for you.
- Reduced friction: Eliminates repetitive manual approvals for recurring actions.
The AUTHCALL Operation
AUTHCALL empowers smart contracts to execute transactions impersonating an authorized address. Think of it as a "digital assistant" that performs tasks in your name, such as automated DeFi trades or subscription payments.
Use cases:
- Batch transactions: Execute multiple actions in a single call.
- Gas abstraction: Allow sponsors to cover gas fees for users.
Benefits of EIP-3074
Enhanced Security
- Separation of authorization and execution reduces attack vectors (e.g., phishing).
User Experience Improvements
- Fewer manual signatures needed for DApp interactions.
- Supports gasless transactions via sponsored meta-transactions.
DeFi Innovation
- Enables complex transaction flows (e.g., atomic swaps, automated portfolio rebalancing).
Flexible Account Management
- Shared control for multisig or institutional setups.
Practical Applications

- Gasless Experiences: Users interact with DApps without holding ETH for fees.
- Automated Services: Recurring payments or DeFi strategies execute autonomously.
- Enterprise Adoption: Businesses can delegate transaction workflows securely.
Risks and Mitigations
While EIP-3074 introduces powerful capabilities, risks include:
- Over-delegation: Unrestricted authority grants could lead to abuse.
- Smart contract vulnerabilities: Flaws in AUTHCALL logic might be exploited.
Solutions proposed by the community:
- Expiry timestamps for authorizations.
- Scoped permissions (e.g., limiting fund access).
EIP-3074 and Ethereum’s Roadmap
This upgrade synergizes with other proposals:
- EIP-2930: Optimizes gas costs with access lists.
- EIP-1559: Fee market reform for predictable pricing.
Together, they aim to make Ethereum scalable, affordable, and intuitive.
FAQs
Q: When will EIP-3074 go live?
A: Expected with the Pectra hard fork in late 2024.
Q: Can EIP-3074 reverse unauthorized transactions?
A: No—authorizations are immutable once broadcast. Always verify trusted callers.
Q: Does this replace Ethereum account abstraction (ERC-4337)?
A: No, EIP-3074 offers a complementary approach for specific use cases.
Q: How does AUTHCALL impact gas fees?
A: It may reduce costs by batching operations, but complex calls could increase fees.
Conclusion
EIP-3074 marks a paradigm shift in Ethereum transaction design. By enabling secure delegation and contract-driven actions, it paves the way for richer DeFi ecosystems and mainstream adoption.
