In recent weeks, the blockchain community has witnessed a notable shift in strategy among two of the most prominent platforms in the ecosystem: Ethereum and Base. After months of intensive negotiations and technical deliberations, both networks have decided to part ways on the pursuit of a single, universal wallet standard.
This decision marks a turning point for developers, users, and service providers who had hoped for a seamless, cross‑chain experience. Ethereum, the world’s leading smart‑contract platform, is moving forward with the implementation of EIP‑8141. This improvement proposal introduces a new transaction format designed to enhance security, improve gas efficiency, and provide better support for emerging use cases such as account abstraction and layer‑2 scaling solutions. The proposal has been refined through multiple rounds of community feedback, formal reviews, and test‑net deployments, and it now enjoys broad consensus among core developers and major stakeholders.
On the other side of the equation, Base—an L2 solution launched by Coinbase—has chosen to adopt a different specification, EIP‑8130. While EIP‑8130 shares some conceptual similarities with its Ethereum counterpart, it diverges in key technical details, including signature handling, fee calculation, and compatibility layers for existing wallet infrastructure.
Base’s team argues that this approach better aligns with their roadmap for rapid onboarding, lower transaction costs, and tighter integration with Coinbase’s own custodial services. The split has immediate practical implications. Wallet providers that aim to support both Ethereum and Base will now need to implement two distinct transaction pipelines. This means handling separate data structures, validation rules, and user interface cues to ensure that users are aware of which network they are interacting with and what fee regime applies.
For decentralized applications (dApps) that operate across both chains, the development effort increases as they must accommodate two sets of APIs and potentially reconcile differing security models. Why did the negotiations break down after such a long period of discussion?
Several factors contributed to the outcome. First, the technical requirements of each network evolved at different paces. Ethereum’s focus on maintaining backward compatibility while introducing advanced features forced a conservative approach to any new standard. Base, meanwhile, prioritized speed to market and the ability to offer lower fees, which led them to favor a more lightweight and flexible specification.
Second, governance structures differ: Ethereum’s improvement proposals undergo a rigorous, community‑driven review process, whereas Base, being a product of a single corporate entity, can make swift executive decisions. These contrasting decision‑making models created friction when trying to converge on a single set of rules. From a user perspective, the divergence may initially feel like a setback. Historically, the promise of a unified wallet experience has been a major selling point for the broader adoption of decentralized finance.
Users have grown accustomed to the idea that a single seed phrase or hardware device could manage assets across multiple networks without needing to switch contexts. With the current landscape, however, users will need to pay closer attention to the network they are transacting on, verify that their wallet software supports the appropriate standard, and possibly manage separate fee expectations. Despite these challenges, there are still pathways to mitigate the impact. Many wallet developers are already working on abstraction layers that can automatically detect the network and apply the correct transaction format behind the scenes.
Some are exploring modular plugin architectures that allow developers to add support for new standards without overhauling the entire codebase. Additionally, cross‑chain bridges and relayers can serve as intermediaries, translating transactions from one format to another where feasible, though this adds latency and may introduce additional trust assumptions. Looking ahead, the ecosystem is likely to see a period of adaptation.
Developers will invest time in updating SDKs, documentation, and user education materials. Exchanges and custodial services will need to adjust their onboarding flows to clearly differentiate between Ethereum‑native and Base‑specific transaction types.
Meanwhile, the broader community will continue to monitor the performance and security outcomes of both EIP‑8141 and EIP‑8130, gathering data that could inform future attempts at standardization. It is also worth noting that the split does not preclude future convergence. History shows that standards often evolve through iterative, sometimes divergent, paths before eventually coalescing around a common baseline.
Should both networks demonstrate robust, secure implementations and the market demand a unified experience, a new collaborative effort could emerge, potentially building on the lessons learned from EIP‑8141 and EIP‑8130. In summary, the decision by Ethereum and Base to pursue separate wallet standards after extensive talks reflects deeper differences in technical priorities, governance models, and strategic objectives. While this creates short‑term complexity for wallets, dApps, and end‑users, the industry is well‑equipped to develop solutions that bridge the gap. The ongoing evolution of these standards will be a key area to watch as the blockchain space strives for greater interoperability, user friendliness, and security.
