Developers from Wonderland have proposed adopting a universal address format in Ethereum that clearly indicates the corresponding L2 network, aimed at preventing errors in cross-chain operations.
Experts have drafted preliminary versions of complementary standards ERC-7930 and ERC-7828, covering the necessary changes.
ERC-7930 defines a binary format for displaying the “network+address” pair and is intended for data exchange between machines such as smart contracts and off-chain agents. Additionally, a text version is provided for debugging and other technical tasks.
ERC-7828 describes a human-readable representation built on top of ERC-7930. The standard relies on decentralized name registries like ENS to link understandable text identifiers such as alice.eth@optimism.eth with the corresponding machine addresses.
According to the developers, the proposed standards will significantly enhance the user experience within the ecosystem by utilizing familiar ENS names across multiple networks.
For wallets, block explorers, protocols, and applications, the standard unifies the way addresses from any network are handled and provides a “building block” for creating cross-chain systems.
Back in April, Ethereum proposed increasing the gas limit by 100 times.
