Ethereum and Base Account Abstraction Standards Diverge

Collaboration between Ethereum and Base on a unified Account Abstraction (AA) standard has ended, with both chains pursuing separate paths. Ethereum is prioritizing EIP-8141 for its upcoming Hegotá upgrade, while Base is moving forward with EIP-8130. Ethlabs researcher Derek Chiang noted that this split reflects differing design philosophies, as Ethereum focuses on L1 security and decentralization, while Base prioritizes L2 scalability and user experience. This divergence may force wallet developers to support multiple transaction formats, raising concerns about potential fragmentation in the wallet ecosystem.
