Ethereum continues to evolve with innovations aimed at improving accessibility, usability, and efficiency. Among the most promising proposals shaping its future is EIP-3074, a technical enhancement designed to introduce sponsored transactions directly into the Ethereum protocol. This guide explores what EIP-3074 is, how it works, its benefits, security considerations, and its role in Ethereum’s broader roadmap toward account abstraction.
Understanding EIP-3074
EIP-3074 is an Ethereum Improvement Proposal that introduces two new operations to the Ethereum Virtual Machine (EVM): AUTH and AUTHCALL. These opcodes enable a trusted third party—such as a dApp or service provider—to pay gas fees for users, effectively sponsoring their transactions.
The AUTH operation allows a user (externally owned account, or EOA) to authorize a specific smart contract—called an invoker—to act on their behalf. This authorization is stored securely within the user’s account and can be revoked at any time. Once authorized, the invoker uses AUTHCALL to execute transactions as if they were initiated directly by the user.
This mechanism enables gasless transactions, where users sign a transaction without specifying gas price or limit. A sponsor then wraps this signature, adds gas payment, and submits it to the network.

Key Benefits of Sponsored Transactions
- Improved user experience: Users no longer need to hold ETH solely for gas, reducing friction when interacting with dApps.
- Greater accessibility: Newcomers unfamiliar with gas mechanics can participate seamlessly.
- Innovative business models: Projects can cover transaction costs to attract users, offer premium services, or bundle fees into subscriptions.
Solving Real-World Challenges
Two major pain points in Ethereum adoption are high gas fees and onboarding complexity. During network congestion, simple transactions can cost more than their intended value—discouraging casual use. Additionally, managing gas requires technical understanding that many users lack.
While solutions like meta-transactions have attempted to solve this, they often rely on off-chain infrastructure and trust assumptions. Many require relayers to front gas costs and involve complex architectures that hinder scalability and security.
EIP-3074 addresses these limitations by integrating sponsorship natively into the protocol. It eliminates reliance on external relayer networks and minimizes trust requirements through cryptographic enforcement and secure contract patterns.
Research indicates that native support for sponsored transactions could significantly lower barriers to entry, especially for non-crypto-native users who find wallet management overwhelming.
Security Implications and Safeguards
With any protocol-level change, security is paramount. EIP-3074 introduces powerful capabilities—and with them, potential risks.
Secure Invoker Contracts
Invoker contracts must be rigorously audited. Since they act on behalf of users, vulnerabilities could lead to unauthorized fund transfers or data manipulation. Best practices include:
- Multi-signature controls
- Time-locked authorizations
- Whitelisting approved actions
The Ethereum Research community has emphasized designing invokers with minimal permissions and clear audit trails.
Phishing Protection
A major concern is phishing: malicious actors might trick users into authorizing rogue invokers. To counter this, EIP-3074 supports a phishing protection registry, allowing wallets and interfaces to verify whether an invoker is legitimate before authorization.
Wallets can display warnings or block known malicious contracts, enhancing user safety without compromising functionality.

EIP-3074 and the Ethereum Ecosystem
The impact of EIP-3074 extends beyond convenience—it could reshape how users engage with decentralized applications.
Lowering Barriers to Entry
One of the biggest hurdles for new users is needing ETH just to pay gas—even when using token-based dApps. With EIP-3074, services can sponsor gas for onboarding flows, enabling frictionless sign-ups, NFT mints, or DeFi interactions without requiring upfront ETH.
This shift could dramatically increase adoption across gaming, social platforms, and real-world applications.
Enabling New Business Models
Developers gain flexibility in monetization:
- Freemium dApps that cover gas for basic actions
- Subscription services bundling transaction costs
- Brands sponsoring transactions for marketing campaigns
Such models align incentives between platforms and users, fostering loyalty and engagement.
Boosting Liquidity and Activity
When users aren’t deterred by gas costs, they’re more likely to transact frequently. This increased velocity enhances liquidity for ERC-20 tokens and NFTs, leading to more dynamic markets and better price discovery.
Relationship with Account Abstraction
EIP-3074 complements Ethereum’s journey toward account abstraction, a vision where user accounts become smarter, more flexible, and programmable.
While full account abstraction (e.g., via ERC-4337 or RIP-7560) enables features like multi-sig wallets, session keys, and AI agents managing funds, EIP-3074 provides a simpler, near-term step: gas sponsorship via EOAs.
Unlike ERC-4337—which relies on off-chain mempools and bundlers—EIP-3074 operates at the protocol level, offering faster finality and tighter integration with existing tooling.
Together, these initiatives build toward a future where Ethereum feels as seamless as traditional web apps—without sacrificing decentralization or control.
Current Status and Future Outlook
As of 2025, EIP-3074 remains under active review and discussion within the Ethereum community. It has not yet been activated on mainnet but is considered a strong candidate for inclusion in upcoming upgrades such as the Pectra upgrade.
Experts are evaluating both its potential and risks:
- Some warn that improper implementation could expose users to novel attack vectors.
- Others argue that with proper safeguards, the benefits far outweigh the risks.
Community-driven debate reflects Ethereum’s decentralized governance model—ensuring robust scrutiny before deployment.
If implemented, EIP-3074 would mark a pivotal advancement in making Ethereum truly user-centric.
Frequently Asked Questions (FAQ)
Q: Can EIP-3074 allow someone else to steal my funds?
A: No—if properly implemented. The AUTH operation only grants permission to make calls on your behalf; it does not give access to private keys or unrestricted fund movement. Malicious activity would still require vulnerabilities in the invoker contract.
Q: Do I need to hold ETH after EIP-3074 is live?
A: Not necessarily. If a dApp sponsors your transactions, you can interact without holding ETH. However, holding ETH may still be useful for unsponsored actions or emergency recoveries.
Q: How is EIP-3074 different from ERC-4337?
A: EIP-3074 works at the protocol level using new EVM opcodes and supports EOAs directly. ERC-4337 achieves similar goals off-chain using bundlers and user operation mempools, enabling smart contract wallets without protocol changes.
Q: Will EIP-3074 reduce gas prices overall?
A: Not directly. It doesn’t lower base fees but shifts who pays them. However, widespread sponsorship could indirectly reduce per-user cost burdens.
Q: Who can become a transaction sponsor?
A: Any entity willing to pay gas—dApps, protocols, businesses, or individuals. Sponsors must run infrastructure to collect signed authorizations and submit transactions.
Q: Is EIP-3074 reversible?
A: Yes. Users can revoke authorization at any time via their wallet interface, stopping any further actions by the invoker contract.
Final Thoughts
EIP-3074 represents a critical leap toward making Ethereum more inclusive and intuitive. By enabling native transaction sponsorship, it removes one of the most persistent friction points in blockchain interaction: gas management.
When combined with broader efforts like account abstraction, EIP-3074 paves the way for a future where decentralized applications feel as smooth as centralized ones—while preserving user sovereignty.
As development progresses, staying informed about proposals like EIP-3074 ensures you're prepared for the next wave of innovation on Ethereum.
