Summary
-
Solving Cross-Chain Confusion: Ethereum is introducing two new standards, ERC-7930 and ERC-7828, to create a universal method for clearly identifying which blockchain network an address belongs to, tackling a major usability issue.
-
Dual Approach for Clarity: ERC-7930 provides a standardized format for computer systems to recognize an address’s specific chain, while ERC-7828 aims to create simpler, human-readable address formats (e.g., user@chainname) for easier recognition by users.
-
Enhanced User Experience and Security: These standards are expected to simplify cross-chain transactions, significantly reduce the risk of sending assets to the wrong network, and are nearing finalization (targeted for May 9th) for implementation in wallets and protocols.
Addressing Cross-Chain Address Ambiguity
Ethereum developers are advancing two interconnected proposals, designated ERC-7930 and ERC-7828, designed to resolve a long-standing usability challenge within the network and its associated blockchains: the lack of a standardized method for clearly identifying addresses across different chains.
The core issue stems from the current difficulty users and applications face in unambiguously associating a specific address with its originating blockchain.
As the Wonderland team, contributors to Ethereum and other decentralized systems, highlighted, there is currently no universal protocol for wallets, applications, or underlying blockchain mechanisms to interpret or display this crucial chain-specific information.
During a recent Ethereum L2 Interop Working Group discussion, Wonderland detailed how these forthcoming standards, conceptualized as “interoperable addresses,” aim to significantly improve the clarity and safety of interactions spanning multiple chains.
Introducing ERC-7930 & ERC-7828: A Dual Approach
The proposed solution utilizes a two-pronged approach to cater to different needs within the ecosystem.
-
ERC-7930 (Technical Standard): This proposal establishes a standardized format specifically for computer systems. It ensures that applications can programmatically and reliably determine the exact blockchain network to which a given address belongs.
-
ERC-7828 (User-Facing Standard): Complementing the technical standard, ERC-7828 focuses on creating human-readable address formats. Instead of relying solely on lengthy, complex strings of characters, users could see more intuitive identifiers, potentially resembling familiar formats like username@chainname, making cross-chain addresses much easier to recognize and verify.
Enhancing User Experience and Preventing Errors
For end-users, the implementation of these standards promises a markedly simpler and safer experience when conducting transactions between different networks.
By replacing potentially confusing strings with clear, chain-associated names, the risk of costly errors, such as sending funds to the correct address but on the wrong network, is substantially reduced.
This simplification facilitates smoother navigation within the expanding landscape of interconnected blockchains and sidechains.
As explained by Wonderland’s pseudonymous developer, Teddy, the fundamental concept involves augmenting existing address information with an explicit chain identifier, ensuring clarity about where an address resides.
Finalization Timeline and Call for Community Input
With a target finalization date set for May 9th, ERC-7930 and ERC-7828 are nearing readiness for adoption.
Following final approval, implementation is anticipated across essential ecosystem components, including digital wallets, block explorers, and cross-chain communication protocols.
To ensure broad consensus, the Wonderland team is soliciting final feedback from the community via dedicated threads on the Ethereum Magicians forum before the proposals reach their definitive “final call” status.
