EIP-3074 is a groundbreaking Ethereum improvement proposal designed to revolutionize user interaction with the Ethereum network by introducing sponsored transactions. This innovation aims to simplify blockchain operations, reduce financial barriers, and enhance accessibility for both new and experienced users. By enabling third parties to cover gas fees, EIP-3074 paves the way for a more inclusive and seamless decentralized ecosystem.
At its core, EIP-3074 introduces two new operations to the Ethereum Virtual Machine (EVM): AUTH and AUTHCALL. These functions allow users to authorize trusted smart contracts—called invokers—to execute transactions on their behalf, with another party paying the associated gas costs. This mechanism eliminates the need for users to hold ETH solely for gas, significantly lowering the entry barrier for mainstream adoption.
How EIP-3074 Works
The technical foundation of EIP-3074 lies in two novel opcodes:
AUTH: Allows a user (externally owned account, or EOA) to sign a message authorizing an invoker contract to act on their behalf. This authorization is stored securely in the user’s account state and can be revoked at any time.AUTHCALL: Enables the authorized invoker contract to make a call that appears to originate directly from the user’s address, using their identity and nonce, while the sponsor covers the gas.
This setup allows for gasless transactions, where users interact with dApps without pre-funding their wallets. Instead, a dApp, service provider, or platform can sponsor the transaction—similar to how web2 platforms absorb infrastructure costs for user actions.

Solving Real-World Challenges
Ethereum has long faced criticism over high transaction costs and complex user workflows. EIP-3074 directly addresses two major pain points:
1. High Gas Fees
During network congestion, gas prices can spike dramatically, making small transactions economically unviable. EIP-3074 mitigates this by allowing businesses or protocols to absorb these costs, ensuring consistent user experience regardless of market conditions.
2. Poor Onboarding Experience
New users often struggle with concepts like gas, wallets, and private keys. Requiring them to purchase ETH before interacting with a dApp creates friction. With sponsored transactions, users can engage immediately—similar to signing up for a free trial—enhancing conversion rates and retention.
Compared to earlier solutions like meta-transactions—which require off-chain relays and complex infrastructure—EIP-3074 offers a native, streamlined approach built into the protocol layer, reducing reliance on external systems and improving security.
Security Considerations
While EIP-3074 brings substantial benefits, it also introduces new security dynamics that must be carefully managed.
Secure Invoker Design
Invoker contracts must be rigorously audited and designed with safeguards such as:
- Time-locked authorizations
- Multi-signature requirements
- Rate-limiting mechanisms
These prevent misuse and ensure that even if compromised, damage is contained.
Phishing Protection
A major concern is phishing attacks, where malicious actors trick users into authorizing rogue invokers. To combat this, EIP-3074 proposes a phishing protection registry, allowing wallets and interfaces to flag known safe (or unsafe) invokers. Users would receive warnings before authorizing untrusted contracts.
Wallet developers play a critical role here—by integrating verification layers and clear UI cues, they can help users make informed decisions.

Impact on the Ethereum Ecosystem
EIP-3074 has far-reaching implications across multiple dimensions of the Ethereum ecosystem.
Enhanced User Adoption
By removing the need to manage gas, EIP-3074 makes Ethereum accessible to non-crypto-native users. Imagine signing up for a DeFi app or minting an NFT without ever touching ETH—this frictionless experience could drive mass adoption.
New Business Models
Developers gain flexibility in designing economic models:
- Freemium dApps offering gasless trades
- Subscription services bundling transaction costs
- Game publishers covering in-game actions
Such models align incentives between platforms and users, fostering loyalty and engagement.
Increased Asset Liquidity
When transaction costs are no longer a deterrent, users are more likely to move assets frequently. This boosts liquidity across DeFi protocols, NFT marketplaces, and tokenized ecosystems—leading to tighter spreads and better price discovery.
Relationship with Account Abstraction
EIP-3074 complements broader efforts toward account abstraction, particularly ERC-4337 and proposed RIP-7560. While ERC-4337 achieves similar goals through higher-layer standards (without protocol changes), EIP-3074 offers a native protocol-level solution that enhances efficiency and reduces overhead.
Together, these initiatives aim to transform EOAs into smart contract wallets capable of advanced functionality—like session keys, social recovery, and batched transactions—while maintaining backward compatibility.
EIP-3074 serves as a critical stepping stone toward full account abstraction by proving the viability of sponsored interactions within the core protocol.
Current Status and Future Outlook
As of 2025, EIP-3074 remains under active review within the Ethereum community. It is being considered for inclusion in upcoming upgrades such as the Pectra hard fork, which aims to enhance wallet functionality and scalability.
Key debates center around:
- Potential attack vectors from poorly implemented invokers
- Long-term implications for network decentralization
- Balancing innovation with security
Despite concerns, there is growing consensus that EIP-3074’s benefits outweigh risks—provided robust implementation standards are adopted.
Once deployed, EIP-3074 could catalyze a new wave of innovation, much like ERC-20 did for tokens or ERC-721 for NFTs.
Frequently Asked Questions (FAQ)
Q: Can I revoke authorization after granting it via AUTH?
A: Yes. Users retain full control and can revoke access at any time through a dedicated revocation function.
Q: Who pays for the gas in a sponsored transaction?
A: A third party—the sponsor—such as a dApp or service provider—covers the gas fees when submitting the transaction.
Q: Is EIP-3074 live on Ethereum mainnet?
A: Not yet. As of 2025, it remains in proposal stage and awaits final approval and integration into a future network upgrade.
Q: Does EIP-3074 require users to share private keys?
A: No. Authorization occurs through cryptographic signatures without exposing private keys to invokers or sponsors.
Q: How does EIP-3074 differ from ERC-4337?
A: EIP-3074 operates at the protocol level with new EVM opcodes, while ERC-4337 is a higher-layer standard implemented entirely in smart contracts.
Q: Could EIP-3074 lead to spam attacks?
A: The risk exists but can be mitigated through rate limiting in invoker contracts and network-level safeguards during implementation.
