Ethereum Layer 2s and the Race for Smart Contract Wallet Standardization

The Ethereum ecosystem is witnessing a significant push towards standardizing smart contract wallets, particularly among Layer 2 solutions. As Layer 2s have been quicker to adopt and develop their own smart contract wallets, the absence of a unified standard has sparked debates and discussions about the future of account abstraction across different layers of the Ethereum network.

The Rise of Layer 2 Smart Contract Wallets

Layer 2 solutions have been at the forefront of integrating smart contract wallets into their chains, driven by the need to enhance user experience and functionality. Unlike the slower-moving Ethereum Layer 1, Layer 2s have "rolled their own code," leading to a proliferation of custom solutions. This rapid development has been beneficial for users, as smart contract wallets offer powerful features and are seen as the future of wallet technology.

However, the downside of this approach is the fragmentation of standards across different Layer 2s. Each solution has its own implementation, which complicates interoperability and creates challenges for developers and users alike. As a result, the Ethereum community is grappling with the need to establish a standard that can be universally adopted.

The Impact on Layer 2 Roadmaps

The ongoing discussions around smart contract wallet standardization are influencing the roadmaps of Layer 2 solutions. The introduction of a standard by Ethereum Layer 1, such as the EIP-7007 proposal, is seen as a step in the right direction. However, experts like Tim from the Ethereum community note that there is still "a lot to unpack" in terms of standardizing account abstraction on Layer 2s.

Key issues that need to be addressed include gas payments, default user onboarding flows, and interoperability across different Layer 2s. These challenges are expected to be focal points for developers and researchers in the coming years. The debate over account abstraction, which has been ongoing since at least 2017, is likely to continue as the community works towards a consensus.

Market Analysis and Expert Predictions

Market analysts have noted that the push for standardization in smart contract wallets could have significant implications for the Ethereum ecosystem. The adoption of a standard could lead to increased interoperability and efficiency, potentially driving more users and developers towards Layer 2 solutions.

According to data from DeFi Llama, the total value locked (TVL) in Layer 2 solutions has been steadily increasing, reaching over $10 billion as of the latest reports. This growth is partly attributed to the user-friendly features offered by smart contract wallets, which are becoming more prevalent in Layer 2 ecosystems.

Experts predict that the standardization of smart contract wallets will be a multi-year process, with incremental improvements and updates being rolled out over time. The EIP-7007 proposal, which aims to introduce a practical step towards standardization, is seen as a positive development but not the final solution.

In addition to smart contract wallets, other Ethereum Improvement Proposals (EIPs) are being discussed, such as the DLS pre-compile for smart contract developers and tweaks to the deposit queue and execution layer withdrawal credentials for validators. These proposals indicate a broader effort to enhance the Ethereum ecosystem's functionality and efficiency.

As the Ethereum community continues to debate and refine the standards for smart contract wallets, Layer 2 solutions will play a crucial role in shaping the future of the network. The outcome of these discussions will have far-reaching implications for the adoption and usability of Ethereum-based technologies.
