Ethereum and Base Diverge on Account Abstraction After Months of Failed Merger Talks

The ongoing evolution of the Ethereum Virtual Machine (EVM) ecosystem has reached a defining crossroads after core developers from Ethereum and Coinbase-backed Layer 2 network Base officially abandoned a months-long initiative to unify their competing account abstraction frameworks. The breakdown of these high-stakes negotiations means that both networks will forge ahead independently, implementing distinct, native account abstraction standards rather than a single, harmonized protocol format. This development marks a significant philosophical shift in how the Ethereum mainnet and its most prominent scaling layers plan to handle user experience, transaction processing, and protocol-level innovation in the years ahead.

Account abstraction has long been heralded by blockchain engineers as a critical milestone for mass adoption. Traditional externally owned accounts (EOAs) require users to manage complex cryptographic private keys, hold native network tokens like Ether (ETH) strictly for transaction fees, and execute operations in rigid, single-step sequences. Account abstraction transforms standard accounts into smart contract wallets, unlocking modern software capabilities such as gas fee payments in stablecoins or application tokens, mobile phone passkey authentication via biometrics, and the batching of multiple transactions into a single, atomic user action. Historically, the shared transaction architecture of the EVM ensured that a single wallet design functioned seamlessly across both Ethereum Layer 1 and its secondary rollup networks. However, the divergence between Ethereum and Base exposes the widening gap between the architectural goals of a secure, decentralized settlement layer and those of high-throughput, enterprise-ready execution environments.

The Breakdown of EIP-8130 and EIP-8141

The failed collaboration centered on reconciling two distinct protocol proposals: EIP-8130, spearheaded by Base developers, and EIP-8141, commonly referred to as Frame Transactions, championed by core contributors on the Ethereum mainnet. Over the course of several months, technical working groups explored various compromises to bridge the gap between the two designs. Ultimately, every potential technical bridge demanded that one side compromise fundamental aspects of its core protocol philosophy.

EIP-8141, which Ethereum core developers have already designated as a mandatory inclusion for the upcoming Hegotá network upgrade, treats transactions as a programmable sequence of execution "frames" or contract calls. This structure allows wallets to handle validation logic, gas abstraction, and zero-knowledge privacy proofs natively within the transaction envelope without requiring constant structural rewrites. Ethereum’s primary optimization vector for Layer 1 remains uncompromisingly focused on long-term censorship resistance, absolute security, maximum privacy, and protocol extensibility.

Conversely, Base and other participating Layer 2 networks are structurally optimized for high transaction throughput, deep customization flexibility, and regulatory compliance features. EIP-8130 introduces an entirely novel transaction format alongside an on-chain keystore that explicitly tracks which authorization keys an account permits. This architecture makes it significantly easier for network sequencers to inspect, parse, and enforce policy rules on incoming transactions, directly supporting high-performance environments and institutional compliance mandates. Base successfully tested iterations of this framework within its experimental "vibenet" sandbox, positioning the standard as an ideal architectural match for the OP Stack.

Reflecting on the collapse of the negotiations, Derek Chiang, a developer at Ethlabs who helped facilitate the coordination talks, noted that the ideological divide proved insurmountable. Both ecosystems prioritized optimizing their respective layers over maintaining cross-layer uniformity. While interoperability remained a shared goal, it was ultimately insufficient to override the distinct developmental trajectories of Layer 1 and Layer 2.

Chronology of the Standard Split

The divergence of Ethereum and Base account abstraction standards is the culmination of a multi-year effort to modernize the user experience of the EVM. The timeline of events leading up to the final split highlights the mounting pressures within the modular blockchain ecosystem:

• 2023–2024: The introduction of ERC-4337 established a smart contract wallet standard on Ethereum without requiring core protocol consensus changes. While successful, ERC-4337 relied on a separate mempool and auxiliary bundlers, introducing higher gas overheads and complexity.
• Early 2025: As Layer 2 adoption surged—led heavily by Base’s explosive growth in transaction volume—developers recognized the urgent need for native, protocol-level account abstraction (NATIVE AA) rather than auxiliary smart contract layers.
• Spring 2026: Base developers introduce EIP-8130 to optimize sequencer inspection and compliance, while Ethereum researchers advance EIP-8141 (Frame Transactions) to secure Layer 1 extensibility and privacy.
• Mid-2026: Formal collaboration talks begin to merge the two designs into a single universal standard, aiming to preserve the unified UX that users and developers had come to expect from the EVM ecosystem.
• September 2026: Technical compromises fail as core contributors realize that forced harmonization would degrade the performance and core objectives of both networks. Talks officially collapse, with both teams announcing independent deployment paths.

Technical Implications for Developers and Wallets

The decision to pursue separate paths introduces immediate logistical friction for application developers, infrastructure providers, and digital wallet creators. If both EIP-8130 and EIP-8141 successfully deploy to their respective networks, the development community will no longer be able to rely on a single transaction type or account logic across the entire Ethereum ecosystem. Wallet applications will be forced to maintain parallel support structures to interact natively with Layer 1’s frame-based architecture and Layer 2’s sequencer-optimized keystore models.

Despite the added complexity, industry analysts argue that the split should not be viewed as a failure of decentralized governance. Forcing a singular compromise design onto two fundamentally different network topologies risked yielding a lowest-common-denominator standard that served neither user base effectively. By decoupling their development roadmaps, Ethereum and Base gain the freedom to innovate rapidly within their respective operational domains.

The burden of bridging this architectural gap will now fall squarely on wallet infrastructure providers. By abstracting the underlying differences between the two protocols through sophisticated user interfaces, modern crypto wallets can theoretically preserve a unified, frictionless experience for end users, masking the underlying cryptographic divergence from the consumer-facing layer.

Broader Economic and Structural Impact on the EVM

Beyond technical implementation details, the split lays bare a deeper, structural tension within the broader Ethereum ecosystem. For nearly a decade, the EVM served as the undisputed, monolithic anchor that kept Ethereum mainnet and its various execution layers tightly aligned both economically and philosophically. However, as the economic and operational interests of Layer 1 and Layer 2 continue to diverge—with Layer 1 focusing on decentralized security and censorship resistance, and Layer 2 prioritizing commercial scalability and regulatory compliance—that foundational layer is experiencing unprecedented strain.

Derek Chiang, outlining the future of the EVM in the wake of the failed merger, suggested that the community faces a fundamental choice. The ecosystem can either establish formal, wide-ranging coordination mechanisms that give Layer 2 networks a formal, binding voice in core EVM governance decisions, or it can accept protocol fragmentation as an inevitable reality of modular blockchain scaling, investing heavily in smart wallet layers designed to paper over the cracks. Chiang’s assessment leans toward the latter, predicting that protocol fragmentation will become a permanent characteristic of the multi-chain era.

Ultimately, the termination of the joint account abstraction initiative does not signal the death of account abstraction itself. Rather, it marks the definitive end of the assumption that a single, monolithic protocol-level design can simultaneously serve the security-maximalist constraints of the Ethereum mainnet and the high-volume, performance-driven demands of modern Layer 2 rollups without severe compromise. As both ecosystems push forward with their independent standards, the responsibility for maintaining a cohesive user experience has shifted decisively from core protocol developers to the wallet and application layer.
