Cross-chain State Committees turn multi-chain states into "citable resources"
The hurdle of cross-chain is "who can I trust". Lagrange uses State Committees built on EigenLayer to create a shared cross-chain security zone: protocols only need to verify a universal state proof, without the need to build their own observer network, and without being trapped by the 7-day challenge period of optimistic Rollups.
The official has disclosed integration with Arbitrum, focusing on "fast finality" for cross-chain access; the technical documentation also explains the combination of its light client committee and re-staking collateral, reducing the fragmentation risk of the traditional "each has their own patch" model. For scenarios like full-chain identity, cross-chain settlement, and cross-chain indexing, this is equivalent to packaging "what happened on other chains" into a standardized API, making it feel more like reading a signed read-only cache, which is worry-free.  
Some information is good to know, after all, there are all kinds of projects in the crypto space
