What is the Ethereum Splurge Phase
The Ethereum Splurge Phase is the final component of Ethereum’s scaling roadmap, designed to handle miscellaneous improvements that don’t fit into other major categories. According to the Ethereum Foundation’s documentation, the Splurge encompasses over 20 Ethereum Improvement Proposals (EIPs) targeting network optimization and user experience enhancements.
Unlike The Surge (focused on scaling) or The Verge (focused on verifier efficiency), the Splurge Phase concentrates on features that make Ethereum more usable and maintainable. The phase includes account abstraction upgrades, EVM improvements, and state management solutions.
Core components include EIP-7702 for delegated smart contract accounts, EOF implementation for better EVM bytecode management, and various state management proposals. These changes work together to reduce complexity for developers while improving the experience for end users.
Why the Splurge Phase Matters
The Splurge Phase matters because it addresses critical usability gaps that limit mainstream Ethereum adoption. Traditional Ethereum accounts require users to manage private keys and pay gas in ETH for every transaction, creating friction for new users unfamiliar with crypto infrastructure.
Account abstraction removes these barriers by allowing smart contract wallets to pay gas in ERC-20 tokens, batch transactions, and implement social recovery features. The Ethereum Foundation’s account abstraction documentation explains how these changes democratize access to decentralized applications.
Beyond user experience, the Splurge Phase tackles technical debt accumulated since Ethereum’s launch. EVM improvements and state management solutions ensure the network remains efficient as transaction history grows over time. These optimizations directly impact node operators’ storage requirements and validators’ computational costs.
Investors should note that Splurge upgrades typically don’t generate dramatic price movements but rather strengthen Ethereum’s long-term utility proposition. The improvements make Ethereum more competitive against alternative layer-1 blockchains that offer simpler user experiences.
How the Splurge Phase Works
The Splurge Phase implements changes through a structured deployment process combining EIP adoption and gradual network upgrades. The following model illustrates the key components and their relationships:
Mechanism Architecture
Account Abstraction Stack:
User Transaction → Entry Point Contract → Smart Contract Wallet → Target DApp
Gas Payment Flexibility: ETH / ERC-20 / Sponsored Transactions
Core EIP Implementation Framework
EIP-7702 (Account Abstraction):
- Temporarily upgrades EOAs to smart contracts during transaction execution
- Enables paymaster contracts for gas abstraction
- Supports transaction batching without protocol forks
EOF (EVM Object Format):
- Separates code from data in EVM bytecode
- Enables static analysis and code validation
- Reduces deployment costs and improves execution efficiency
State Management:
- State expiry reduces historical state requirements
- State rent proposals encourage data pruning
- Historical bucket trie improves state storage efficiency
Deployment Sequence
Phase 1: EOF implementation via hard fork
Phase 2: EIP-7702 adoption with compatibility layers
Phase 3: State management EIPs based on community consensus
This layered approach allows testing and refinement at each stage, minimizing disruption to existing applications. According to Ethereum’s official documentation, developers prioritize backward compatibility wherever possible.
Used in Practice
Application developers are already preparing for Splurge Phase features by redesigning wallet architectures and transaction flows. Smart contract wallets like Argent and Sequence currently implement proprietary account abstraction solutions; EIP-7702 will enable these features natively on protocol level.
Gas sponsoring represents the most immediate practical application. Projects can now subsidize transaction costs for new users, removing the requirement that onboarding involves purchasing ETH first. This approach has proven successful on layer-2 networks and will eventually apply to Ethereum mainnet.
Developers building on Optimism and Arbitrum already experience benefits from account abstraction experiments. These layer-2 deployments serve as testing grounds for Splurge concepts before mainnet implementation. The Optimism documentation demonstrates how account abstraction reduces friction in daily transactions.
NFT marketplaces and gaming applications stand to benefit significantly from transaction batching. Users can approve multiple token transfers in a single transaction, reducing confirmation wait times and overall gas expenditure. This functionality mirrors features already available through ERC-4337 bundlers but with improved efficiency.
Risks and Limitations
Smart contract wallets introduced through account abstraction carry smart contract risk that doesn’t exist with traditional EOA accounts. If the Entry Point contract contains vulnerabilities, users’ funds could be compromised across thousands of wallets simultaneously. Audit firms face increased scrutiny as account abstraction adoption grows.
Complexity increases for developers learning Ethereum development. Account abstraction introduces new patterns around tx.origin behavior, gas estimation, and signature validation. The ecosystem requires updated tooling and documentation to support these changes effectively.
State management proposals remain contentious within the Ethereum community. Proposals like state expiry or state rent could invalidate existing contract assumptions about data accessibility. Projects storing critical data on-chain must prepare migration strategies if these EIPs proceed.
Timeline uncertainty poses challenges for project planning. Unlike The Surge with its clear milestones tied to Proto-Danksharding, the Splurge Phase lacks defined delivery dates. Features may be delayed, combined, or deprioritized based on development progress and community feedback.
The Splurge vs Other Ethereum Roadmap Phases
The Splurge Phase differs fundamentally from The Surge, which focuses on data availability and transaction throughput improvements. The Surge delivers scaling through Danksharding and blob transactions; the Splurge optimizes how users interact with the resulting capacity.
Comparing the Splurge to The Verge reveals distinct optimization targets. The Verge reduces verification costs through Verkle Trees and STARKs, making nodes lighter and faster. The Splurge, conversely, improves the execution layer and user-facing functionality rather than verification mechanics.
Against The Purge, which removes historical data and simplifies the protocol, the Splurge adds capability rather than removing complexity. The Purge streamlines Ethereum’s technical surface; the Splurge enhances its feature set.
Unlike the Scourge, which addresses MEV and validator centralization risks, the Splurge Phase doesn’t directly address consensus layer concerns. The Splurge operates primarily at the application layer, making Ethereum more accessible to users and developers.
What to Watch
Monitor EIP-7702 implementation progress as the most impactful Splurge feature. Developer feedback from early testnet deployments will indicate whether the proposal achieves its account abstraction goals without introducing significant vulnerabilities.
Track EOF adoption rates among smart contract developers. This EVM upgrade represents a breaking change for some existing contracts, and the ecosystem’s readiness for deployment will influence timing decisions.
Watch for state management EIP discussions on Ethereum’s governance forums. These proposals have historically faced implementation challenges due to their broad impact on existing applications. Community sentiment will determine which approaches move forward.
Pay attention to layer-2 implementations of Splurge concepts. Solutions deployed successfully on Arbitrum, Optimism, or Base will inform mainnet upgrade priorities and timing. The Arbitrum ecosystem often serves as a testing ground for Ethereum improvements.
Note developer tooling updates from major frameworks like Hardhat, Foundry, and Truffle. Account abstraction requires new debugging workflows and testing environments that the community must build collectively.
Frequently Asked Questions
When will the Splurge Phase be complete?
No fixed completion date exists for the Splurge Phase. Unlike The Merge with its clear deadline, the Splurge represents ongoing improvements deployed incrementally through multiple Ethereum upgrades.
Do regular Ethereum users need to do anything for Splurge upgrades?
Most users won’t need to take action. Smart contract wallet users may benefit from new features automatically; EOA holders won’t experience changes until adopting compatible wallets.
How does account abstraction affect gas costs?
Account abstraction can reduce effective gas costs through transaction batching and gas sponsorship. However, execution complexity may offset savings for simple transactions.
Is EIP-7702 replacing EIP-4337?
No, EIP-7702 complements EIP-4337 rather than replacing it. Both address account abstraction but through different mechanisms: 4337 uses an alternative mempool; 7702 modifies EOA behavior temporarily.
Will smart contract wallets become mandatory after the Splurge?
EOAs will continue functioning indefinitely. The Splurge enables smart contract wallets without mandating their adoption.
What happens to existing contracts under state expiry proposals?
Contracts may become inaccessible after designated periods under state expiry proposals. Developers must understand access windows and implement appropriate data retrieval mechanisms.
How does the Splurge affect Ethereum’s competitive position against Solana or other L1s?
The Splurge improves user experience but doesn’t directly address throughput competition. Ethereum maintains its security guarantees and decentralization while adding convenience features popular on alternative platforms.
Can developers start building for Splurge features today?
Yes, developer testnets and sandbox environments allow experimentation with EIP-7702 and EOF implementations. Production deployment should await mainnet activation dates.
