Agent-skills evm-chains

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:

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

No

ROUTEMESH_API_KEY

is not available, use the chain's default public RPC instead.
