Ethereum and Base Part Ways on Wallet Standards—What It Means for Layer 2s

Ethereum and Base have hit a wall in their efforts to align on account abstraction standards, according to Ethlabs researcher Derek Chiang. The two networks are now charting separate paths on how they'll handle smart contract wallets, a critical infrastructure decision that could fragment the ecosystem.

The Breakdown

Account abstraction—the tech that lets users create programmable wallets without needing traditional externally-owned accounts (EOAs)—represents a major shift in how crypto wallets function. Instead of users holding private keys for standard Ethereum accounts, account abstraction enables flexible, recoverable, and feature-rich wallet designs.

The failed negotiations between Ethereum's core developers and Base's team suggest fundamental disagreements about implementation standards. Derek Chiang, who tracks these developments at Ethlabs, flagged that the two Layer 2s are now pursuing distinct account abstraction designs rather than converging on a unified approach.

Why This Matters

Fragmentation here is genuinely problematic. A unified standard would make it seamless for users to move between networks using compatible wallet infrastructure. Instead, projects deploying on Ethereum might need different smart contract wallet implementations for Base—complicating portfolio management and trading workflows.

Base, Coinbase's Layer 2 built on the OP Stack, has already become a major hub for crypto activity. If it develops its own account abstraction framework separate from Ethereum's trajectory, we could see wallets optimized for Base that don't play nicely with Ethereum mainnet or other L2s using different standards.

The Bigger Picture

This disagreement highlights broader tensions in how Layer 2s balance autonomy with ecosystem cohesion. Base wants flexibility in its technical decisions; Ethereum's broader community has different priorities. Neither approach is inherently wrong, but the lack of interoperability creates friction.

For traders and portfolio managers, this means keeping tabs on which wallets support which chains. An account abstraction standard that works seamlessly across Ethereum, Base, Arbitrum, and Optimism would be a game-changer for user experience. Without it, we're looking at a patchwork of competing solutions.

The crypto analysis here is straightforward: ecosystem fragmentation typically hurts adoption. When users have to learn different wallet mechanics for different chains, barriers to entry rise. That said, competing implementations sometimes drive innovation faster than committee-consensus approaches.

Derek Chiang's reporting signals that this isn't a minor technical disagreement—it's a fundamental divergence in philosophy. Ethereum mainnet and Base are going to solve the account abstraction problem differently, which matters for developers building cross-chain dapps and for users managing exposure across multiple networks.
