feat: add getter to return all source chain config

0xsuryansh commented 2 weeks ago

Motivation

The current offchain initialization process involves calling getSourceChainConfig(sourceChainSelector), which retrieves configurations for a specific source chain selector. However, there's no mechanism to fetch a complete list of supported source chains during the initialization phase. This limitation complicates the process, as the full list of source chain selectors is not readily available.

Solution

To address this, the proposed solution introduces an enumerable set of all source chain selectors. By implementing a getAllSourceChainConfig() function, we can easily retrieve the complete list of source chains on-chain. This eliminates the need for additional rounds of OCR gossip to share known source chains, simplifying initialization and improving efficiency.
