According to Derek Chiang, a researcher at Ethlabs, Ethereum and the Coinbase-incubated Layer 2 network Base have officially moved in different directions regarding their account abstraction wallet standards. The failure to reach a consensus means that users may face disparate onboarding, gas payment, and transaction signing experiences depending on whether they are interacting with the Ethereum Mainnet or the Base ecosystem. This technical schism marks a pivotal moment in the 2026 roadmap for modular blockchain development.
The negotiations, which were intended to harmonize how smart contract wallets interact with various layers of the ecosystem, reportedly stalled over fundamental differences in technical implementation priorities. Ethlabs noted that while Ethereum continues to refine its native AA roadmap—largely centered on evolving EIP-4337 and its successors—Base is optimizing its standards to better serve its specific high-throughput requirements and its integration with the broader Coinbase product suite.
From a regulatory and geopolitical perspective, this divergence underscores the growing independence of U.S.-based Layer 2 networks from the core Ethereum foundation's technical dictates. While Ethereum remains a global, decentralized standard, Base's move to a proprietary or specialized AA design reflects a trend toward localized optimization. For developers, this necessitates maintaining separate codebases or utilizing complex middleware to ensure that smart contract wallets remain functional across both environments.
Moving forward, the market should watch for how other OP Stack chains respond to this development. If more Layer 2 networks follow Base’s lead, the dream of a 'unified wallet layer' across all of Ethereum’s extensions could be permanently shelved in favor of a fragmented but specialized landscape. Investors should monitor the upcoming Ethereum protocol upgrades scheduled for late 2026 to see if any new EIPs are introduced to bridge this growing technical gap.
