EIP-3074 is a groundbreaking Ethereum Improvement Proposal designed to revolutionize how users interact with the Ethereum network by introducing sponsored transactions. At its core, this proposal aims to simplify the user experience and reduce financial barriers by enabling third parties to pay gas fees on behalf of users. This shift could dramatically expand Ethereum’s accessibility, making decentralized applications (dApps) more intuitive for both newcomers and experienced users.
By addressing long-standing pain points like high transaction costs and complex wallet management, EIP-3074 aligns with Ethereum’s broader vision of scalability, usability, and inclusivity. Let’s dive into the technical foundation, benefits, security considerations, and future implications of this transformative upgrade.
Understanding EIP-3074: The Technical Foundation
According to the official GitHub proposal, EIP-3074 introduces two new opcodes to the Ethereum Virtual Machine (EVM): AUTH and AUTHCALL. These operations are central to enabling secure and efficient transaction sponsorship.
The AUTH opcode allows a user (externally owned account, or EOA) to authorize a designated smart contract—known as a caller—to act on their behalf. This authorization is stored within the user’s account storage and can be revoked at any time, ensuring control remains in the user's hands.
Once authorized, the caller contract uses the AUTHCALL opcode to execute transactions from the user’s address. Crucially, these calls maintain the same execution context as if the user had initiated them directly, preserving integrity and consistency across the network.

This mechanism lays the groundwork for native support of gasless transactions, eliminating the need for complex off-chain relayers or custodial setups that have historically plagued solutions like meta-transactions.
How Sponsored Transactions Work
Sponsored transactions under EIP-3074 allow a third party—such as a dApp developer, service provider, or enterprise—to cover the gas costs associated with a user’s on-chain activity. Here's how it works:
- A user signs a transaction without specifying gas price or limit.
- A sponsor retrieves this signed message and pays the required gas fee.
- The sponsor submits the transaction to the network via an authorized caller contract.
This process removes the necessity for users to hold ETH solely for gas payments—a major hurdle for onboarding non-crypto-native individuals.
Key benefits include:
- Improved user experience: No need to pre-fund wallets with ETH.
- Greater accessibility: Lowers entry barriers for new users unfamiliar with blockchain mechanics.
- Innovative business models: Enables services like subscription-based dApps where gas fees are bundled into monthly plans.
As adoption grows, we may see gaming platforms, social networks, and fintech apps using sponsored transactions to offer seamless, wallet-free interactions.
Addressing Core Challenges in Ethereum UX
EIP-3074 directly tackles two persistent issues: high gas fees and cumbersome user workflows.
During periods of network congestion, gas prices can spike unpredictably, making small-value transactions economically unviable. For instance, transferring $5 worth of tokens might cost $15 in gas—an obvious deterrent.
While previous solutions like meta-transactions attempted to solve this, they often required trust in third-party relayers who held partial signing rights or managed off-chain infrastructure. These systems introduced complexity, latency, and potential security risks.
EIP-3074 offers a cleaner alternative by embedding sponsorship directly into the protocol layer. With native support through AUTH and AUTHCALL, there's no reliance on external relays or custodial setups, reducing trust assumptions and improving reliability.

Security Considerations and Safeguards
Despite its advantages, EIP-3074 introduces potential attack vectors that require careful mitigation.
One concern is caller contract security. Since these contracts act on behalf of users, they must be rigorously audited. Best practices include implementing multi-signature controls, rate limiting, and time-locked authorizations to prevent abuse.
Another risk involves phishing attacks, where malicious actors trick users into authorizing rogue caller contracts. To counter this, EIP-3074 proposes a phishing protection registry—a verifiable list where legitimate callers can register their addresses. Wallets and interfaces can then cross-check authorizations against this registry before confirming approvals.
Additionally, because AUTH grants temporary but powerful permissions, clear user interface indicators will be essential. Users must understand exactly what they’re approving and retain easy revocation mechanisms.
Impact on the Ethereum Ecosystem
The implications of EIP-3074 extend far beyond convenience—it could catalyze widespread adoption and innovation across the ecosystem.
Lowering Barriers to Entry
Many potential users abandon dApps due to confusion over gas fees or reluctance to manage private keys. With EIP-3074, services can absorb transaction costs, offering a frictionless experience akin to traditional web platforms.
Imagine signing up for a DeFi app without needing ETH in your wallet—your first swap or deposit is fully sponsored. This model mirrors freemium offerings in Web2 and could accelerate mainstream adoption.
Enabling New Business Models
Developers gain flexibility in monetizing their platforms:
- Offer premium features with sponsored transactions as part of a paid tier.
- Bundle gas costs into service fees, creating predictable pricing.
- Launch onboarding campaigns where initial interactions are gas-free.
Enterprises integrating blockchain can also streamline B2B processes by covering gas for partners or customers, fostering smoother collaboration.
Boosting Liquidity and Market Efficiency
With reduced friction, users may engage in more frequent asset transfers. This increased activity can enhance liquidity for ERC-20 tokens and NFTs, leading to better price discovery and tighter spreads across decentralized exchanges.
Relationship with Account Abstraction
EIP-3074 complements broader efforts toward account abstraction, particularly ERC-4337 (also known as EIP-4337). While ERC-4337 enables smart contract wallets with advanced features like session keys and paymasters, it operates entirely off-chain via an EntryPoint contract.
In contrast, EIP-3074 brings similar capabilities—like gas sponsorship—directly into the EVM through native opcodes. It serves as a stepping stone toward full account abstraction while being simpler to implement in the near term.
Other proposals like RIP-7560 aim for native account abstraction too, but EIP-3074 stands out for its focused scope and backward compatibility with existing EOAs.
Together, these initiatives push Ethereum toward a future where accounts are more programmable, secure, and user-centric.
Current Status and Future Outlook
As of 2025, EIP-3074 remains under active discussion within the Ethereum community. It has not yet been implemented but is being considered for inclusion in upcoming network upgrades such as the proposed Pectra hard fork.
Debate continues around potential risks, especially regarding smart contract vulnerabilities introduced by AUTH and AUTHCALL. However, proponents argue that with proper safeguards—such as standardized caller templates and wallet-level verification—the benefits outweigh the risks.
Community feedback plays a crucial role in shaping its final design. Developers, researchers, and stakeholders are encouraged to participate in discussions on GitHub, Ethereum Magicians, and core developer calls.
If approved, EIP-3074 could roll out within the next major upgrade cycle, marking a pivotal step toward mass adoption.
