After months of negotiations aimed at unifying how wallets interact across their networks, Ethereum and Coinbase-backed Base have abandoned efforts to agree on a common standard, leaving developers to grapple with competing systems.
A Split Over Standards
The disagreement centers on two rival technical proposals. Ethereum is pressing forward with EIP-8141, while Base has thrown its weight behind EIP-8130. The failure to reconcile the two means wallets and applications that operate across both chains will now have to accommodate different transaction frameworks depending on which network they touch.
The talks had stretched on for months, reflecting how difficult it can be to align priorities between an open, community-driven blockchain like Ethereum and a corporate-backed layer-2 network such as Base. Both sides ultimately concluded that pushing their preferred approach was preferable to a compromise neither fully embraced.
Two of crypto's most closely linked networks are now walking separate paths on a question meant to bring them together.
What It Means for Developers
For builders, the divergence introduces added complexity. Wallets and apps designed to function seamlessly across Ethereum and Base may need to support two distinct transaction systems rather than a single unified one. That could increase development overhead and complicate the user experience for people moving between the networks.
The outcome is notable given the tight relationship between the two ecosystems. Base is built as a layer-2 network settling on Ethereum, and the two are often seen as deeply intertwined. A shared wallet standard was viewed as a way to smooth interoperability and reduce friction for the broader user base.
Key takeaways from the split include:
- Ethereum is advancing EIP-8141 as its chosen path.
- Base is backing the alternative EIP-8130.
- Cross-network wallets and apps face fragmented transaction systems.
For now, the crypto community will be watching to see whether either standard gains broader adoption, or whether the fracture prompts renewed efforts to bridge the divide down the line.
