Ethereum and Base Abandon Unified Wallet Standard After Prolonged Discussions

In recent weeks the blockchain community has witnessed a decisive shift in the approach taken by two major platforms—Ethereum and the Coinbase‑backed Layer‑2 solution known as Base—regarding a shared wallet standard that had been the subject of extensive negotiations for months. The outcome of those talks is that each network will now pursue its own distinct improvement proposal, leaving developers, wallet providers, and end‑users who operate across both chains to adapt to two separate transaction models.

## Background and the original goal of a common standard The idea of a unified wallet standard emerged from a desire to simplify the user experience for those who hold assets on both Ethereum’s mainnet and on Base, which inherits much of Ethereum’s security model while offering lower fees and faster finality. A single standard would have meant that a wallet could construct, sign, and broadcast transactions in an identical format regardless of the underlying network, thereby reducing the need for duplicate code paths, minimizing the risk of bugs, and fostering smoother cross‑chain interactions. Two proposals were at the heart of the discussion: EIP‑8141, championed by the Ethereum core developers, and EIP‑8130, which received strong backing from the Base team and its parent company, Coinbase. Both drafts aimed to introduce a new transaction envelope that would support advanced features such as account abstraction, batch processing, and more expressive fee mechanisms.

However, subtle differences in how each proposal handled signature validation, gas pricing, and compatibility with existing smart contracts led to a protracted debate. ## Why the talks broke down The negotiations spanned several months and involved multiple working groups, community polls, and technical review sessions. While there was broad agreement on the need for an upgraded transaction format, the two camps diverged on three critical technical points: 1.

**Signature Scheme Flexibility** – EIP‑8141 advocated for a strict adherence to the secp256k1 curve, preserving backward compatibility with the majority of existing wallets. EIP‑8130, on the other hand, opened the door to alternative signature schemes such as Ed25519 and BLS, which could enable novel use‑cases like multi‑signature wallets but required more extensive changes to the client software. 2. **Fee Market Design** – The Ethereum proposal retained the legacy base‑fee and tip model introduced by EIP‑1559, whereas Base’s draft introduced a dynamic, market‑driven fee auction that could better reflect Layer‑2 demand but would complicate fee estimation for users accustomed to Ethereum’s predictable pricing.

3. **Roll‑up Compatibility** – Base, being a roll‑up, needed a format that could be efficiently aggregated and proved on‑chain.

EIP‑8130 included specific fields for batch identifiers and proof metadata, features that were not present in EIP‑8141 and would have required additional engineering effort for Ethereum validators. When the working groups attempted to reconcile these differences, they found that any compromise would either dilute the benefits of each proposal or impose a heavy implementation burden on both networks. The consensus eventually coalesced around the view that pursuing separate standards would allow each chain to optimize for its own performance goals without being constrained by the other’s requirements.

## Implications for wallets and dApps The decision to diverge has several practical consequences: - **Dual Integration Effort** – Wallet developers will now need to maintain two distinct transaction builders. This means supporting both EIP‑8141 and EIP‑8130 libraries, handling different fee calculations, and ensuring that signatures are generated according to the appropriate scheme for each network. - **User Experience Fragmentation** – End‑users may notice subtle differences when switching between Ethereum and Base within the same application.

For example, the fee preview UI might display a base‑fee on Ethereum but a market‑driven estimate on Base, potentially causing confusion for newcomers. - **Security Audits** – Each standard will undergo its own audit process. While this can lead to more thorough scrutiny tailored to the specific chain, it also means that security teams must allocate resources to two codebases rather than focusing on a single, unified implementation. - **Cross‑Chain Tooling** – Projects that aim to provide seamless cross‑chain functionality—such as bridges, aggregators, and multi‑chain explorers—will need to incorporate logic that detects the target chain and applies the correct transaction format.

This adds a layer of complexity but also opens opportunities for innovative adapters that abstract away the differences for end‑users. ## Potential benefits of separate paths Although the split may appear as a setback for standardization, there are strategic advantages: - **Tailored Innovation** – Base can experiment with cutting‑edge fee mechanisms and signature schemes without being limited by Ethereum’s legacy constraints.

This could lead to faster iteration cycles and the introduction of features that eventually inform future Ethereum upgrades. - **Performance Optimization** – By designing a transaction format specifically for roll‑up environments, Base can achieve lower latency and higher throughput, reinforcing its value proposition as a high‑speed, low‑cost alternative for everyday transactions.

- **Risk Isolation** – If a vulnerability is discovered in one standard, it does not automatically affect the other network. This separation can act as a safety valve, limiting the blast radius of potential exploits.

## What developers should do now For teams building on either or both platforms, the immediate steps are: 1. **Assess Current Dependencies** – Identify any libraries, SDKs, or smart contracts that assume a single transaction format. Pinpoint where changes will be required to support both EIP‑8141 and EIP‑8130. 2.

**Implement Abstraction Layers** – Create a thin abstraction that selects the appropriate transaction builder based on the destination chain. This pattern will simplify future updates and keep the codebase maintainable. 3. **Update Documentation** – Clearly communicate to users the differences they may encounter, especially around fee estimation and signature options.

Transparent guidance can mitigate confusion and improve adoption. 4.

**Participate in Community Testing** – Both Ethereum and Base are likely to roll out test‑net versions of their respective proposals. Engaging with these test environments early will help uncover integration issues before mainnet deployment. ## Looking ahead While the dream of a single, universal wallet standard for Ethereum and Base has been set aside for now, the broader ecosystem continues to evolve toward greater interoperability.

Initiatives such as cross‑chain messaging protocols, standardized token bridges, and shared identity solutions remain active areas of research. In the long term, the experience gained from implementing and operating two distinct transaction formats may inform a future convergence, perhaps through a third‑generation proposal that harmonizes the best aspects of both EIP‑8141 and EIP‑8130. In summary, the decision to pursue separate wallet standards reflects a pragmatic response to technical realities and strategic priorities. Developers, wallet providers, and users should prepare for a period of dual‑format support, while also recognizing the opportunities for innovation and optimization that each network can now pursue independently.
