In recent weeks, the blockchain community has been closely watching the unfolding debate over a shared wallet standard that could simplify cross‑network transactions for users of Ethereum and the emerging Base layer‑2 solution. After months of negotiations, both projects have now signaled that they will pursue separate technical pathways, effectively ending the push for a single, unified standard.
Ethereum’s development team has officially endorsed EIP‑8141, a proposal that introduces a new transaction format designed to improve scalability, reduce gas costs, and enhance the overall user experience on the mainnet. The proposal, which has been through several rounds of community review and testing, focuses on optimizing the way transaction data is encoded and processed by Ethereum nodes. By adopting EIP‑8141, Ethereum aims to streamline transaction handling, support future upgrades such as sharding, and lay the groundwork for more sophisticated smart contract interactions. At the same time, Base – a layer‑2 network launched by Coinbase to provide fast, low‑cost transactions while staying anchored to Ethereum’s security model – has chosen to back a different improvement, EIP‑8130.
This proposal targets a complementary set of challenges, emphasizing compatibility with Base’s roll‑up architecture and the specific needs of its user base. EIP‑8130 introduces a distinct transaction schema that better aligns with Base’s optimistic roll‑up design, allowing for quicker finality and reduced latency for end‑users.
While the two proposals share the overarching goal of improving transaction efficiency, their technical details diverge significantly. The decision to split on these standards carries important implications for developers, wallet providers, and end‑users who operate across both networks. Previously, many wallets and decentralized applications (dApps) hoped to implement a single codebase that could seamlessly handle transactions on Ethereum and Base, leveraging a common interface to reduce development overhead.
With the adoption of separate standards, developers will now need to maintain dual implementations, ensuring that their software can correctly interpret and sign both EIP‑8141 and EIP‑8130 transaction formats. This added complexity may increase development costs and could introduce a higher risk of bugs or incompatibilities. For wallet providers, the divergence means updating user interfaces to clearly distinguish between the two transaction types. Users may be prompted to select the appropriate network when initiating a transfer, and the wallet must correctly serialize the transaction according to the chosen standard.
Some wallets are already working on modular architectures that allow plug‑in style support for multiple standards, but the shift will still require extensive testing and user education to avoid confusion. From a broader ecosystem perspective, the split highlights the challenges of achieving consensus across independent blockchain projects, even when they share a common security foundation.
Ethereum and Base are both committed to advancing the user experience, yet their differing priorities—Ethereum’s focus on long‑term scalability and Base’s emphasis on immediate transaction speed—have led to distinct technical solutions. This outcome underscores the reality that a single, universal wallet standard may be difficult to achieve when layer‑2 solutions have unique design constraints.
Nevertheless, the community remains optimistic that interoperability tools will emerge to bridge the gap. Projects such as cross‑chain bridges, meta‑transaction relayers, and SDKs that abstract away the underlying transaction format are already in development. These solutions aim to provide a seamless experience for users who move assets between Ethereum and Base, despite the underlying technical differences. In summary, the decision by Ethereum to move forward with EIP‑8141 and by Base to adopt EIP‑8130 marks the end of the effort to create a unified wallet standard for both networks.
While this introduces additional work for developers and wallet providers, it also reflects the natural evolution of a diverse blockchain ecosystem where each layer‑2 solution tailors its protocols to meet specific performance and user‑experience goals. The industry will now focus on building robust tooling and best‑practice guidelines to ensure that the coexistence of multiple standards does not hinder the broader adoption of decentralized finance and blockchain technology.
