In recent weeks the blockchain community has witnessed a notable divergence between two of the most prominent public‑layer networks: Ethereum and Base, the latter being the Layer‑2 solution launched by Coinbase. After months of back‑and‑forth negotiations, the two projects have decided to abandon the idea of a unified wallet standard that would have allowed developers and users to move assets and execute transactions across both ecosystems using a single, seamless protocol.
Instead, each chain is moving forward with its own improvement proposal – Ethereum with EIP‑8141 and Base with EIP‑8130 – a development that will have far‑reaching consequences for wallet providers, decentralized applications (dApps), and anyone who regularly interacts with both networks. ### The background of the proposed common standard The original goal of a common wallet standard was to simplify the user experience for those who hold assets on both Ethereum and Base.
By agreeing on a single set of transaction semantics, developers could write code once and have it work on both chains without needing to maintain separate code paths. The proposal was especially attractive for multi‑chain wallets, DeFi platforms, and NFT marketplaces that already support a growing list of Layer‑1 and Layer‑2 networks.
A shared standard would also have reduced the risk of bugs and inconsistencies that can arise when developers try to translate one chain’s transaction format into another’s. ### Why the talks stalled Despite the clear benefits, the discussions encountered several technical and governance hurdles.
Ethereum’s community, which follows a rigorous EIP (Ethereum Improvement Proposal) process, placed a high priority on backward compatibility and the preservation of existing transaction semantics. The EIP‑8141 draft, which eventually won the internal vote, focuses on enhancing transaction privacy, introducing a new fee‑calculation model, and adding optional fields that improve composability for advanced smart‑contract interactions.
These changes were seen as essential for Ethereum’s long‑term roadmap, especially as the network prepares for upcoming upgrades that aim to increase throughput and reduce gas costs. Base, on the other hand, is a relatively newer chain that benefits from the backing and strategic direction of Coinbase. Its engineering team emphasized speed of deployment and alignment with the existing Coinbase wallet ecosystem. The EIP‑8130 proposal reflects those priorities: it introduces a streamlined transaction format that reduces the data payload, thereby lowering latency for high‑frequency trading and gaming use cases.
It also incorporates a different approach to fee estimation that better matches Base’s optimistic roll‑up architecture. When the two groups attempted to reconcile their differences, they discovered that the core design choices – such as how to handle transaction signatures, the order of fields in the binary encoding, and the mechanisms for fee refunds – were fundamentally incompatible. Compromise would have required either Ethereum to adopt a less optimal fee model for the sake of uniformity, or Base to accept a more complex transaction structure that could hamper its performance targets.
Neither side was willing to sacrifice the strategic advantages that their respective proposals offered. ### The decision to go separate ways Ultimately, after a series of community polls, technical reviews, and stakeholder meetings, the consensus emerged that pursuing a single standard would delay critical upgrades on both chains. Ethereum’s developers voted to push EIP‑8141 forward, citing the proposal’s alignment with the network’s broader roadmap toward scalability and security.
Meanwhile, Base’s leadership formally announced the adoption of EIP‑8130, highlighting the need for a lightweight transaction format that can support the high‑throughput applications that Coinbase envisions for its user base. The split was formally communicated in a joint statement that emphasized mutual respect and a commitment to interoperability through other means, such as bridge protocols and cross‑chain messaging standards. While the two chains will continue to support each other’s assets via established bridges, the underlying transaction mechanics will remain distinct.
### Practical implications for wallets and dApps For wallet developers, the immediate impact is the need to implement dual transaction handling logic. This means updating SDKs, API endpoints, and user‑interface components to recognize whether a user is interacting with Ethereum or Base and to construct the appropriate transaction payload accordingly.
Many popular multi‑chain wallets have already begun rolling out beta support for EIP‑8130, but full production‑grade integration will likely take several weeks, if not months, of testing and user education. Decentralized applications that operate on both layers will also need to adapt. Smart‑contract developers must be mindful of the differing fee structures, as a transaction that is cheap on Base could be comparatively expensive on Ethereum once EIP‑8141’s new fee model is live.
Moreover, cross‑chain functionalities – such as atomic swaps or multi‑hop bridges – will have to incorporate logic that translates between the two transaction formats, potentially increasing the complexity of smart‑contract code and audit requirements. ### What this means for end users From a user perspective, the most noticeable change will be the appearance of two distinct transaction confirmation screens when moving assets between Ethereum and Base. Users will need to be aware of which network they are on, as the fee estimates and confirmation times will differ. Educational material from wallet providers and exchanges will become essential to prevent confusion, especially for newcomers who may not yet understand the nuances of Layer‑2 scaling solutions.
Despite the added complexity, the split also brings benefits. Ethereum’s EIP‑8141 promises enhanced privacy features and more flexible fee calculations, which could improve the experience for DeFi participants and developers building privacy‑focused protocols. Base’s EIP‑8130, with its streamlined payload, is expected to deliver faster transaction finality, making it an attractive platform for gaming, micro‑transactions, and high‑frequency trading.
### Looking ahead The decision to pursue separate standards does not signal an end to collaboration between Ethereum and Base. Both communities have pledged to continue working on bridge security, cross‑chain messaging, and shared tooling that can abstract away the underlying differences for developers. In the longer term, the industry may see the emergence of higher‑level interoperability layers that sit on top of the native transaction formats, providing a unified developer experience without forcing the underlying protocols to converge.
In summary, while the abandonment of a common wallet standard represents a setback for the ideal of a seamless multi‑chain user experience, it also reflects the practical realities of balancing technical innovation with network‑specific goals. Wallets, dApps, and users will need to adapt to the dual ecosystem, but the continued focus on interoperability and the development of robust bridging solutions should ensure that the broader ecosystem remains cohesive and vibrant.
