As the Ethereum ecosystem continues to evolve, the need for seamless interoperability between the ever-expanding Layer 2 (L2) networks has become critical. Ethereum co-founder Vitalik Buterin recently announced It was revealed A comprehensive plan to address this challenge aims to create a seamless user experience across the entire “Ethereum universe” and overcome the current fragmented ecosystem by improving layer-to-layer communication and multi-layer interoperability.
Addressing the Layer 2 Compatibility Challenge
Buterin recognizes that the complexity and inefficiency of trading assets between different L2 networks, such as Optimistic Pools, Plasma, and State Channels, has long been a pain point for DeFi users and developers. In response, he highlighted a roadmap for Ethereum Improvement Proposals (EIPs) that aim to standardize how these networks communicate and execute cross-chain transactions, enable seamless cross-chain asset swaps, and improve blockchain interoperability.

EIP-3370: Standardization of Address Formats
A key step in this process is EIP-3370, which introduces a new address standard to be adopted by wallets and decentralized applications (dApps) across EVM-compatible chains. This standard will allow chain-specific addresses to be displayed using human-readable prefixes, making it easier for users to navigate the Ethereum ecosystem and promoting cryptocurrency interoperability.
EIP-7683: Establishing a connection over L2
Another important proposal is EIP-7683, which aims to create a standard set of rules that all Ethereum L2 networks, including those using cross-chain technologies like Connext and Hop Protocol, can follow to facilitate seamless communication and exchange of assets. This would alleviate the current complexity and inefficiencies associated with cross-chain trading and improve cross-chain liquidity.

EIP-3668: Enable Layer 2 Light Clients
Buterin also highlighted EIP-3668, a proposal that outlines a way for Ethereum smart contracts to access off-chain data in a standardized manner. The concept, referred to as “layer 2 light clients,” allows developers to build applications that require large amounts of data without incurring high on-chain storage costs, enhancing composability across layer 2 scaling solutions like the Validium and Polkadot chains.
Replayable account state updates via L2
In addition to the EIP proposals, Buterin discussed the concept of “replayable computation state updates via L2,” which he previously outlined in Blog postThis approach aims to enable L2s to receive the latest L1 state updates while maintaining security and low latency, enhancing the cross-chain experience and facilitating roll-to-roll transfers.
Go to ZK-Rollups
Buterin also shared his vision for the future of Ethereum scaling solutions, stating that he believes all staking will eventually move to zero-knowledge (ZK) technology. He believes this shift will be necessary to achieve once-per-slot finality on the Ethereum mainnet, which he estimates will take at least 5 years to achieve, and will further improve blockchain interoperability solutions.
Decentralization Achievement in Optimism
Buterin praised Optimism for its recent success in achieving decentralization in the first phase, which includes implementing a centralized security council that can override root submissions in the event of errors. This achievement represents a significant step forward in enhancing the security and decentralization of Ethereum’s L2 ecosystem and improving interoperability between layers.
Al Qaeda’s Decentralization Roadmap
Buterin also highlighted the efforts of Base, the Ethereum L2 network backed by Coinbase, which aims to achieve phase one decentralization by 2025. This will include implementing fault-tolerant measures on the mainnet, enhancing the security and resilience of the Ethereum ecosystem, and enabling seamless cross-chain communication.
The importance of meeting the needs of all levels of users
In a separate appearance, Buterin emphasized the need for Ethereum developers to balance the needs of Web3 newcomers with seasoned dApp users. He stressed the importance of creating applications that are easy enough for the general public to use while maintaining the core values of decentralization and self-custody, which can be facilitated by liquidity networks like Connext and Composable Finance.
Leveraging CeFi Platforms for Mass Adoption
Buterin acknowledged the pivotal role that centralized finance (CeFi) platforms, such as Coinbase, can play in helping surface-level crypto users engage in on-chain activity. He believes that by integrating these platforms and leveraging automated market makers, the Ethereum ecosystem can better serve the needs of the millions of users already involved in the cryptocurrency market.
Achieving a seamless experience across the chain
Buterin emphasized the need for developers to reduce friction in transferring assets and accessing decentralized applications across different L2 networks, emphasizing his vision of an Ethereum world where Layer 2 feels like an integral part of Ethereum, rather than 34 separate blockchains. This can be achieved through the use of cross-chain liquidity solutions such as General Token Bridge, Hop Bridge Tokens, and LiquidityPoolManager.
Conclusion
Vitalik Buterin’s comprehensive plan to address interoperability between L2 chains in the Ethereum ecosystem demonstrates his visionary leadership and commitment to creating a seamless user experience. By leveraging a suite of EIPs, innovative approaches to account state updates, and a focus on decentralization, Buterin and the Ethereum community are paving the way for a future where L2 networks truly feel like an integral part of the Ethereum ecosystem, supported by arbitrary data networks and data availability layers.
