Treat any chain missing from the tables as outside this skill's local dataset. If the requested chain is not listed, use the web search tool to find authoritative metadata from the chain's official documentation or Chainlist before proceeding.\n\n## RouteMesh\n\nUse RouteMesh only when the `RouteMesh` column is `Yes` and the `ROUTEMESH_API_KEY` environment variable is available.\n\nConstruct the RouteMesh RPC URL as:\n\n```text\nhttps://lb.routeme.sh/rpc/CHAIN_ID/ROUTEMESH_API_KEY\n```\n\nReplace `CHAIN_ID` with the numeric chain ID and `ROUTEMESH_API_KEY` with the value of the `ROUTEMESH_API_KEY` environment variable. If `RouteMesh` is `No` or `ROUTEMESH_API_KEY` is not available, use the chain's default public RPC instead.\n\n## Mainnets\n\n| Chain name | Chain ID | Default public RPC | Native currency symbol |
