Ethereum and Base abandon shared wallet standard, creating multi-chain incompatibility

Ethereum and Coinbase-backed Base have ended efforts to align on a common account abstraction standard, according to CoinDesk reporting. Ethereum is moving ahead with EIP-8141, while Base is backing EIP-8130, a separate standard developed independently. Account abstraction refers to a set of protocol rules that determine how transactions are authorized and processed on a blockchain. When standards diverge between chains, wallets and applications that operate across both networks must maintain separate code paths for each chain's requirements, creating friction in multi-chain user experience and developer workflow. Per CoinDesk, the collaboration between the two chains broke down after months of talks.Cointelegraph reports that each chain is now developing its account abstraction standard independently. The sources do not indicate whether the two standards will eventually converge or remain permanently distinct. The failed collaboration signals that even well-resourced, major chains struggle to coordinate on protocol design when implementation philosophy, governance philosophy, or risk tolerance diverge. No statement from either the Ethereum Foundation or Coinbase on the reasons for the breakdown appears in the available reporting.
