Foundry Cast CLI

Overview

Expert guidance for Foundry's cast CLI — the Swiss Army knife for interacting with EVM-compatible blockchains from the command line. Use this skill for signing transactions, sending them to chain RPCs, reading on-chain state, encoding/decoding ABI data, and managing wallets.

Key capabilities:

• Send transactions and call contracts via RPC
• Sign messages and typed data
• Encode and decode ABI calldata
• Query balances, transaction receipts, and block data
• Resolve ENS names and addresses
• Manage keystores and wallet operations

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-chains marks the chain as not supported by RouteMesh, use the chain's default public RPC instead.
