Ethereum and Base Split on Account Abstraction After Standards Talks Fail

A split at the standards level matters more than any single wallet feature: account abstraction touches how users sign, pay fees and recover accounts, so divergent designs can harden into ecosystem lock-in and raise integration costs for wallets and app developers serving both chains. The immediate burden falls on teams building across Ethereum and Base, who now face two technical paths instead of one. Whether the camps later reconverge, or whether tooling emerges to bridge the two designs, is the open question.
