Summary
This wraps Foundry's cast CLI for on-chain operations: sending transactions, calling contracts, encoding ABI data, and managing wallets. It defaults to RouteMesh RPCs when available and prioritizes browser wallet signing so you never paste private keys into chat. The Multicall3 batching guidance is solid for reducing RPC round-trips when reading multiple values. The skill enforces environment variable checks before hitting the chain, which saves you from half-signed transactions. If you're doing any EVM work in the terminal, this handles the tedious parts of constructing RPC URLs, picking signing methods, and decoding calldata without memorizing cast flags.
