In recent weeks the blockchain community has witnessed a notable shift in strategy among two of the most prominent platforms in the ecosystem: Ethereum, the world’s leading smart‑contract network, and Base, the Layer‑2 solution backed by Coinbase. After months of negotiations, technical workshops, and community consultations, both projects have decided to move forward with separate transaction standards rather than converging on a single, unified wallet protocol. This decision marks the end of an extended period of collaboration that aimed to simplify cross‑chain interactions for users, developers, and wallet providers, but ultimately proved too complex to reconcile given the divergent priorities and technical constraints of each network. ### Background: The quest for a common standard The idea of a shared wallet standard originated from a shared desire to reduce friction for end‑users who frequently move assets between Ethereum and Base.

Both chains use the same underlying Ethereum Virtual Machine (EVM) and share many of the same tooling and developer resources, which led many in the community to believe that a single transaction format could be adopted across both layers. Such a standard would have allowed a wallet to generate a single transaction payload that could be broadcast on either chain without modification, streamlining the user experience and lowering the barrier for developers building multi‑chain applications.

Two proposals emerged as the leading candidates: **EIP‑8141**, championed by the Ethereum core developers, and **EIP‑8130**, which was drafted by the Base team in close collaboration with Coinbase engineers. Both drafts sought to address similar pain points—namely, the need for a more expressive transaction format that supports advanced features like fee markets, pay‑master contracts, and batch execution—while preserving backward compatibility with existing infrastructure. ### Why the split happened Despite the shared objectives, several technical and governance issues began to surface as the working groups dug deeper into the specifications: 1. **Fee model divergence**: Ethereum continues to evolve its fee mechanism around the base fee and priority fee model introduced by EIP‑1559, whereas Base, leveraging its close relationship with Coinbase, has experimented with alternative fee structures that prioritize transaction throughput and cost predictability for retail users.

Aligning these models within a single standard would have required significant compromises that could dilute the benefits each chain was seeking. 2. **Governance and upgrade cadence**: Ethereum’s upgrade process is notoriously deliberate, involving extensive peer review, multiple testnets, and a broad consensus among core developers, researchers, and ecosystem participants.

Base, on the other hand, operates under a more centralized governance model, allowing for faster iteration and deployment of new features. The differing timelines made it difficult to synchronize a joint rollout without risking delays on either side. 3. **Security assumptions**: The two proposals introduced subtle but important differences in how transaction signatures are verified and how replay protection is handled across layers.

Ethereum’s approach places a strong emphasis on preserving the security guarantees of the mainnet, while Base’s design incorporates additional checks tailored to its roll‑up architecture. Reconciling these security models without introducing new attack vectors proved to be a non‑trivial challenge.

4. **Community consensus**: Both EIPs attracted robust discussion on public forums, with developers, wallet providers, and users weighing in.

While there was enthusiasm for a unified standard, the majority of feedback ultimately reflected a preference for each chain to retain control over its own transaction format, ensuring that optimizations could be made independently. Given these factors, the working groups concluded that pursuing two parallel standards would allow each network to move forward at its own pace, incorporate feedback from its specific user base, and avoid the risk of a compromised, “one‑size‑fits‑all” solution that might have hindered innovation.

### What this means for wallets and dApps The immediate impact of the decision is that wallet developers now need to support **both EIP‑8141 and EIP‑8130** if they wish to offer seamless experiences across Ethereum and Base. This entails implementing dual transaction encoding paths, handling distinct fee calculations, and ensuring that signature verification logic respects the nuances of each standard.

While this adds a layer of complexity, many major wallet providers have already begun integrating the necessary code branches, leveraging modular design patterns that make it easier to maintain multiple transaction schemas. For decentralized applications (dApps) that aim to be cross‑compatible, the split encourages a more explicit handling of chain‑specific logic. Developers will likely adopt abstraction layers that detect the underlying network at runtime and automatically select the appropriate transaction format. In practice, this could look like a library that exposes a unified API—`sendTransaction(params)`—while internally routing the request through the correct EIP implementation based on the target chain identifier.

### Future outlook and potential convergence Although the two standards are diverging for now, the broader ecosystem remains hopeful that lessons learned from the parallel implementations will eventually converge. Both EIP‑8141 and EIP‑8130 share many core concepts, and future iterations may incorporate cross‑compatibility bridges or translation layers that allow a transaction crafted for one standard to be interpreted by the other with minimal friction. Moreover, the dialogue sparked by this effort has already yielded valuable insights into how Layer‑2 solutions can interoperate with the Ethereum mainnet without sacrificing performance or security. The ongoing research around meta‑transactions, pay‑master contracts, and batch processing continues to benefit both communities, even if the standards themselves remain distinct.

### Conclusion In summary, the decision by Ethereum to advance with **EIP‑8141** and by Base to adopt **EIP‑8130** reflects a pragmatic recognition of each network’s unique technical roadmap and governance model. While wallets and applications that span both ecosystems will need to accommodate two transaction formats, the separation also opens the door for tailored innovation on each chain.

As the blockchain space matures, the experience gained from this episode will likely inform future attempts at standardization, ensuring that any eventual convergence is built on a solid foundation of security, usability, and community consensus.
