EIP-7888은 체인 간 메시지를 표준화된 방식으로 브로드캐스트하는 Crosschain Broadcaster 인터페이스를 제안합니다. 이 표준은 멀티체인 생태계에서 상호 운용성을 향상시키기 위한 ERC Draft입니다.
Problem Statement
Cross-chain messaging protocols are numerous and incompatible, forcing developers to write custom integration code for each bridge or messaging layer. A standard broadcaster interface would abstract over these differences.
Interface Design
The ERC defines a broadcast function that accepts a target chain ID, target address, and message payload. Implementations wrap the specific cross-chain transport (e.g., LayerZero, Hyperlane, or native bridges) behind this common API.
Benefits
Protocol developers can write chain-agnostic code that works with any compliant broadcaster. Upgrades to the underlying transport layer do not require changes to the calling contracts.
Status
EIP-7888 is in Draft and gathering community input on the function signatures, fee handling, and acknowledgement patterns.
