Ethereum and Base abandon shared wallet standard after prolonged discussions

The blockchain ecosystem has long been driven by the promise of interoperability, especially when it comes to the user experience of moving assets and executing transactions across different networks. In recent months, however, two of the most prominent platforms in the Ethereum ecosystem—Ethereum itself and the Coinbase‑backed Layer‑2 solution Base—have reached a crossroads that could reshape how developers and users interact with these chains. After an extended period of negotiations and technical deliberations, the two projects have decided to abandon the pursuit of a common wallet standard. Instead, each network is moving forward with its own distinct improvement proposal: Ethereum is advancing with EIP‑8141, while Base is championing EIP‑8130.

This divergence means that wallets, decentralized applications (dApps), and other infrastructure tools that aim to support both networks will now have to accommodate two separate transaction systems, rather than a single, unified approach. ### Background: The Quest for a Unified Standard The original goal of a shared wallet standard was to simplify the user experience across multiple Ethereum‑compatible chains. By agreeing on a single set of transaction formats, signature schemes, and data structures, developers could write code once and have it work seamlessly on any chain that adopted the standard.

This would reduce friction for end‑users, who would no longer need to worry about compatibility issues when moving funds between, for example, the Ethereum mainnet and a Layer‑2 rollup. The conversation began in earnest in early 2023 when several key stakeholders—including Ethereum core developers, wallet providers, and Layer‑2 teams—identified the need for a more streamlined approach to transaction handling. The idea was to create a universal standard that could be implemented by both the base layer and any number of scaling solutions built on top of it.

Such a standard would cover everything from basic transaction fields to more advanced features like fee markets, gas estimation, and support for emerging account abstraction concepts. ### The Proposals: EIP‑8141 vs. EIP‑8130 As the dialogue progressed, two competing proposals emerged.

Ethereum’s community gravitated toward EIP‑8141, which builds on the existing transaction format but introduces enhancements aimed at improving security, reducing transaction size, and better supporting account abstraction. EIP‑8141 emphasizes backward compatibility, ensuring that legacy transactions continue to be valid while offering a clear migration path for newer, more efficient transaction types.

Conversely, Base, the Layer‑2 solution backed by Coinbase, championed EIP‑8130. This proposal takes a slightly different route, focusing on optimizing transaction throughput for rollup environments and incorporating features that are particularly beneficial for high‑frequency trading and DeFi applications. EIP‑8130 also proposes a novel fee‑payment mechanism that aligns more closely with Base’s own economic model, allowing users to pay fees in a broader set of assets and potentially reducing overall transaction costs.

Both proposals are technically sound and have strong arguments in their favor. However, the core differences—especially around fee handling, transaction encoding, and the extent of backward compatibility—proved to be sticking points during the negotiations. ### Why the Split Occurred Several factors contributed to the decision to abandon a single, shared standard: 1.

**Technical Divergence**: The underlying design philosophies of the two proposals began to diverge significantly. While EIP‑8141 prioritizes a smooth transition from the current Ethereum transaction model, EIP‑8130 aims to push the envelope on performance and flexibility for rollups.

Reconciling these approaches without compromising the strengths of either proved increasingly complex. 2. **Timeline Pressures**: Both Ethereum and Base have ambitious roadmaps that include upcoming upgrades, fee market changes, and new scaling solutions. The need to ship these improvements on schedule left little room for a prolonged standard‑unification effort.

3. **Stakeholder Alignment**: Wallet providers and dApp developers expressed differing priorities.

Some valued the stability and predictability of EIP‑8141, while others were eager to adopt the more aggressive performance gains promised by EIP‑8130. Achieving consensus across this diverse group was challenging. 4. **Economic Considerations**: Base’s fee model, which allows for multi‑asset fee payment, is a strategic differentiator for the platform.

Aligning this model with Ethereum’s more traditional fee structure would have required significant compromises on both sides. Given these challenges, the two communities concluded that pursuing separate standards would allow each network to move forward at its own pace, delivering the promised improvements to users without further delay. ### Implications for Wallets and dApps The most immediate impact of this split will be felt by wallets and decentralized applications that aim to support both Ethereum and Base. Developers will now need to implement dual transaction handling logic, ensuring that the correct format is used depending on the target chain.

This may involve: - Detecting the destination network and automatically selecting the appropriate EIP (8141 for Ethereum, 8130 for Base). - Providing users with clear UI cues that indicate which transaction format is being used, especially when fees can be paid in different assets. - Maintaining compatibility layers for legacy transactions on both chains, to avoid breaking existing user balances and contract interactions.

While this adds a layer of complexity, many wallet teams are already accustomed to supporting multiple standards across the broader Ethereum ecosystem (e.g., ERC‑20, ERC‑721, ERC‑1155). The new requirement is essentially an extension of that multi‑standard support, albeit with a focus on transaction construction rather than token handling. ### Looking Ahead Both EIP‑8141 and EIP‑8130 are slated for inclusion in upcoming network upgrades.

Ethereum’s roadmap indicates that EIP‑8141 will be part of the next major hard fork, bringing its enhancements to the mainnet within the next year. Base, meanwhile, plans to roll out EIP‑8130 alongside its own scaling upgrades, positioning the network as a high‑throughput alternative for DeFi and NFT projects.

In the longer term, the community may revisit the idea of a unified standard once the individual proposals have matured and the ecosystem has had time to adapt. Lessons learned from implementing both standards in parallel could inform a future convergence effort, potentially leading to a more robust and flexible universal standard. For now, developers, wallet providers, and users should prepare for a dual‑standard environment. By building flexible tooling and staying informed about the specifics of each EIP, the ecosystem can continue to thrive, delivering the promised benefits of faster, cheaper, and more secure transactions across both Ethereum and Base.
