EIP-8048은 토큰 레지스트리를 위한 온체인 메타데이터 표준을 제안하는 Draft ERC입니다. 토큰 이름, 심볼, 소수점 자릿수 등의 메타데이터를 레지스트리 컨트랙트에서 표준화된 방식으로 저장하고 조회할 수 있게 합니다.
Motivation
Token registries aggregate information about multiple tokens but currently lack a standardized way to store and expose token metadata on-chain. EIP-8048 proposes a common interface for registry contracts to expose token name, symbol, decimals, and other attributes. This enables consumers to query registries without relying on off-chain data sources.
Metadata Schema
The proposed standard defines a set of required and optional metadata fields that a token registry must expose. Required fields include token name, symbol, and decimal precision. Optional fields may include description, logo URI, and categorization tags. The schema is designed to be extensible without breaking existing implementations.
On-Chain Queryability
Having metadata stored on-chain allows smart contracts and decentralized applications to query token properties without trusted oracles or off-chain APIs. This is particularly valuable for on-chain governance systems, DEX aggregators, and automated portfolio tools. Standardization reduces integration costs for developers.
Draft Status
As a Draft, EIP-8048 is seeking feedback on the metadata schema, the registry interface design, and update mechanisms for mutable metadata fields. Versioning and access control for metadata updates are open design considerations. The proposal aims to complement existing token standards like ERC-20 and ERC-721.
