Ethereum and Base Abandon Shared Account-Abstraction Standard

The split matters less as a technical dispute than as a coordination signal: account abstraction was pitched as base-layer unification, and the two largest ecosystems diverging on it pushes complexity onto wallet teams, who must now choose or maintain parallel support. That fragmentation risk sits with builders, not end users, at least initially. Whether one format gains de facto dominance through wallet adoption, or the two coexist as a persistent compatibility tax, is the open question worth tracking.
