Ethereum and Base abandon plans for unified programmable wallet standard

Ethereum and Base have ended discussions to align on a single transaction format for programmable wallets, opting for separate paths. Ethereum will proceed with EIP-8141, while Base, the rollup backed by Coinbase (Coinbase), will implement EIP-8130. This divergence requires developers to maintain two distinct codebases for wallets and applications, though the ERC-5792 standard may help mitigate cross-chain compatibility issues. Both proposals aimed to advance native account abstraction, a long-standing goal to move beyond traditional externally owned accounts (EOAs).
