description: This skill should be used when the user asks to resolve an EVM chain name or chain ID, find chain metadata such as a default public RPC or native currency symbol, determine whether a chain is supported by RouteMesh, or needs chain resolution before fetching data from or interacting with an EVM chain.

# EVM Chains

Local EVM chain reference for chain name, chain ID, default public RPC, native currency symbol, and RouteMesh support lookups.

Use this skill to resolve chain metadata before reading from an RPC, sending transactions, calling contracts, or constructing chain-specific RPC URLs.

Match chains by displayed name or numeric chain ID. 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.

## RouteMesh

Use RouteMesh only when the `RouteMesh` column is `Yes` and the `ROUTEMESH_API_KEY` environment variable is available.

Construct the RouteMesh RPC URL as:

```text
https://lb.routeme.sh/rpc/CHAIN_ID/ROUTEMESH_API_KEY
```

Replace `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.
