RPC Configuration

All on-chain commands require an RPC endpoint. Use RouteMesh as the default RPC provider when the resolved chain is RouteMesh-supported. If $evm-atlas marks the chain as not supported by RouteMesh, use the chain's default public RPC instead.

URL pattern:

https://lb.routeme.sh/rpc/{CHAIN_ID}/{ROUTEMESH_API_KEY}

Construct the RPC URL by resolving the chain with $evm-atlas first, then reading the ROUTEMESH_API_KEY environment variable if RouteMesh is supported. If $evm-atlas is unavailable, tell the user they can install this skill collection with bunx skills add PaulRBerg/agent-skills; until then, use references/chains.md only as a limited fallback for common networks.

Before running any on-chain command, verify that ROUTEMESH_API_KEY is set:
