Ethereum Proposes ERC-7828 and ERC-7930 to Fix Crosschain Wallet Confusion
Ethereum Developers Unveil New Token Standards to Solve Crosschain UX Woes
May 1, 2025 — Ethereum’s development community is preparing to roll out two new token standards that could dramatically streamline how users and applications navigate between different blockchains. The proposal aims to reduce the friction and financial risk currently tied to crosschain transactions — a growing pain point in the multichain era of decentralized finance (DeFi).
At the center of the initiative are ERC-7930 and ERC-7828, two complementary standards introduced by Wonderland, a coalition of Ethereum ecosystem developers, researchers, and data scientists. These standards seek to create a universal address system for crosschain payments and interactions, benefiting both machines and people.
Why Ethereum’s Crosschain Experience Is Still Broken
Despite Ethereum’s expanding multichain ecosystem, from rollups like Optimism to privacy chains like Aztec, there is no universal rulebook for how wallets, DApps, or smart contracts interpret or present blockchain addresses. As Wonderland put it in a May 1 post:
“The result? A messy, inconsistent experience that breaks cross-chain UX.”
Each wallet or application follows its own logic, forcing users to constantly tweak network settings, often resulting in failed or misrouted transactions. A single Ethereum-compatible address can work on multiple chains — but without context, that flexibility becomes a risk rather than a feature.
Two Standards, One Goal: Frictionless Multichain Transactions
ERC-7930: The Machine’s Language
ERC-7930 introduces a compact, binary address format, designed for technical applications such as APIs and smart contracts. By standardizing how machines read addresses across chains, the format reduces complexity for developers and improves backend consistency.
ERC-7828: The Human’s Interface
ERC-7828 builds on that technical layer by adding human-readable address formats such as wallet123@chainname. This structure lets users immediately identify the correct blockchain, ensuring that funds aren’t accidentally sent to the wrong network.
“Target audience for ERC-7828 is anything that interacts with humans… It’s the text layer,” said Teddy, one of the developers behind the proposal.
A Safer, Simpler Wallet Experience
Under the proposed system, a sender can explicitly designate the destination chain in a transaction using either the machine or human format. This would eliminate the need to manually switch blockchain networks in wallet settings, and help users avoid costly mistakes from address confusion.
With adoption, Ethereum wallets could become truly blockchain-agnostic, offering a cleaner, safer experience as DeFi protocols continue to operate across multiple Layer-1s and Layer-2s.
What’s Next? Community Feedback Urgently Needed
The Ethereum Foundation’s interoperability working group recently reviewed the proposal. According to Wonderland, the goal is to finalize both standards within two weeks, pending public feedback.
Developers are urging the community to weigh in on the ETH-Magicians forum — a hub for shaping Ethereum standards — to ensure these improvements reflect real-world needs.
