In recent weeks, the blockchain community has been closely watching the evolving standards that govern how users interact with decentralized applications (dApps) on various networks. Two of the most prominent platforms, Ethereum and the newly launched Base network—backed by Coinbase—have each decided to pursue separate technical proposals for handling transaction requests, effectively ending a long‑running effort to create a single, universal wallet standard. Ethereum’s roadmap now officially includes the implementation of EIP‑8141, a proposal that introduces a novel transaction format aimed at improving user experience, security, and compatibility with emerging use cases such as account abstraction and layer‑2 scaling solutions.
Meanwhile, Base has announced its commitment to EIP‑8130, a different specification that focuses on a complementary set of features, including enhanced gas‑price flexibility and tighter integration with Coinbase’s own infrastructure. The split is the result of months of back‑and‑forth between developers, wallet providers, and the core engineering teams of both networks.
Early in the year, a joint working group was formed with the explicit goal of harmonising the two proposals into a single, cross‑chain standard. The hope was that a unified approach would simplify the developer experience, reduce fragmentation, and enable end‑users to manage assets on both chains with a single wallet interface. However, as the technical details of each EIP were fleshed out, fundamental differences emerged. EIP‑8141, championed by Ethereum’s core developers, emphasizes a more granular control over transaction fields, allowing for custom signature schemes and the optional inclusion of auxiliary data.
This design aligns closely with the broader Ethereum roadmap that envisions a future where smart contract accounts can act like regular user accounts, blurring the line between externally owned accounts (EOAs) and contract‑based accounts. Proponents argue that this flexibility is essential for supporting sophisticated DeFi protocols, advanced NFT minting processes, and emerging identity solutions.
On the other hand, EIP‑8130 was drafted with a different set of priorities. Base’s engineering team, leveraging its close ties to Coinbase’s custodial and trading services, sought to streamline the transaction flow for high‑throughput applications and to provide a more predictable gas‑fee model.
The proposal introduces a new transaction envelope that can carry multiple operations in a single on‑chain submission, effectively reducing the number of separate calls required for complex workflows. Additionally, it incorporates a built‑in mechanism for dynamic fee adjustment, which is particularly valuable for users transacting on a network that aims to maintain low latency and cost‑efficiency. When the two groups attempted to reconcile these approaches, several sticking points became apparent.
First, the data structures proposed by each EIP are not directly compatible; merging them would require a substantial rewrite of the underlying client software for both networks. Second, the security assumptions differ: EIP‑8141’s emphasis on custom signatures introduces new attack vectors that Base’s team felt were beyond the scope of their immediate risk model. Third, the governance processes for approving and rolling out the standards diverged, with Ethereum’s decentralized improvement proposal (EIP) system operating on a broad consensus model, while Base’s roadmap is more centrally coordinated through Coinbase’s product teams.
Given these challenges, the working group concluded that attempting to force a single standard would likely delay critical upgrades on both chains and could lead to a fragmented ecosystem where developers must maintain two separate codebases. Instead, they opted for a pragmatic split: each network will move forward with its chosen proposal, while a set of interoperability guidelines will be published to help wallet developers bridge the gap.
For wallet providers, this development means that supporting both Ethereum and Base will now involve integrating two distinct transaction schemas. Most major wallets—such as MetaMask, Trust Wallet, and Coinbase Wallet—have already begun work on modular architectures that can load network‑specific handlers at runtime. In practice, a user who holds assets on both Ethereum and Base may see slightly different UI prompts when signing a transaction, depending on which network the operation targets. The underlying cryptographic signing process remains the same (e.g., using ECDSA‑secp256k1 keys), but the payload format and fee calculation logic will differ.
Developers building dApps that aim to be multi‑chain will need to adapt their backend services to detect the active network and format transaction requests accordingly. Many SDKs are being updated to abstract away these differences, offering a unified API that automatically selects the appropriate EIP based on the chain ID. For example, a DeFi protocol that offers liquidity pools on both Ethereum and Base can now expose a single “deposit” function in its front‑end code; the SDK will translate that call into an EIP‑8141‑compatible transaction for Ethereum and an EIP‑8130‑compatible one for Base.
The broader community reaction has been mixed. Some purists lament the loss of a single, elegant standard, fearing that the proliferation of multiple formats could hinder the user experience and slow adoption among non‑technical users.
Others view the decision as a realistic acknowledgment of the diverse needs of different ecosystems. They argue that competition between standards can spur innovation, leading to better solutions overall.
Looking ahead, both Ethereum and Base have committed to ongoing collaboration. The interoperability guidelines will include best‑practice recommendations for cross‑chain token bridges, shared address registries, and standardized error handling. Moreover, the two networks will continue to share research findings on topics such as transaction bundling, gas‑price prediction, and post‑quantum cryptography, ensuring that the divergence in standards does not translate into a divergence in security posture.
In summary, the abandonment of a common wallet standard marks a pivotal moment for the blockchain space. While Ethereum advances with EIP‑8141 and Base adopts EIP‑8130, the ecosystem must adapt to support dual transaction models. Wallet developers, dApp creators, and end‑users alike will need to stay informed about the nuances of each proposal, but the collaborative spirit that underpins both communities promises that seamless cross‑chain experiences will still be achievable, even if they now require a bit more engineering finesse.
