Currently, there is no published ERC-7628 standard in the official Ethereum Improvement Proposals repository. This may be due to several reasons: the standard could be in early draft stages, the numbering might refer to a proposed but not yet finalized ERC, or there may be confusion with a similar ERC number.
Understanding Ethereum Request for Comments (ERCs)
Ethereum Request for Comments (ERC) is a category of EIPs dedicated to application-level standards and conventions. ERCs define how smart contracts, tokens, and decentralized applications should interact on the Ethereum blockchain. These standards ensure interoperability across different platforms, wallets, and applications.
ERC standards specify a base set of functions and events that smart contracts must support, allowing wallets and onchain apps to interact with any compliant token predictably. The ERC process promotes community review to ensure standards meet real-world requirements and operate harmoniously across the ecosystem.
How ERC Numbering Works
ERC numbers are assigned sequentially when proposals are submitted to the Ethereum Improvement Proposal process. The ERC process involves multiple stages: Draft, Review, Last Call, Final, or potentially Withdrawn. Not every number in the sequence results in a published standard, as proposals may be withdrawn, rejected, or remain in draft status indefinitely.
Recently published ERCs in the 7600-7700 range include ERC-7683 cross-chain intents and ERC-7730 for structured data signing. These standards demonstrate the ongoing evolution of blockchain interoperability and improvements in user experience.
Related Standards You Might Be Looking For
If you're researching blockchain standards related to interoperability or user experience, several relevant ERCs exist:
Cross-Chain Standards: ERC-7683 enables cross-chain intents, allowing users to execute complex transactions across multiple blockchain networks through standardized protocols.
Wallet Integration: Blockchain intents represent user-defined goals that solvers execute, simplifying complex operations without requiring users to understand technical implementation details.
The absence of ERC-7628 from official documentation suggests either the standard hasn't been proposed yet, was withdrawn during the review process, or the inquiry might reference a different standard number. For the most current information about Ethereum standards, always consult the official Ethereum Improvement Proposals repository and related documentation.
Key Takeaway: While ERC-7628 isn't currently published, the Ethereum ecosystem continues evolving with new standards for improved interoperability, user experience, and cross-chain messaging capabilities.
