Cli Cast
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.

Foundry Cast CLI
This skill is coordination-exempt: skip the ai-coord gate for its declared work.
Separate read, preparation, simulation, signing, and broadcast. Do not hide state-changing actions inside command construction.
For EIP-7702 authorization or delegation revocation, read references/eip7702.md before preparation. It defines signer selection, authority versus transaction sender, and conditional staged approval. It also defines authorization verification in addition to the transaction receipt.
Resolve Chain and Provider
Invoke $evm-atlas before every network operation. It owns chain resolution, discrete reads, and bounded live
subscriptions. Pass the explicit chain name or ID, JSON-RPC method, exact parameters or call object, and block selector
or checkpoint requirement. State why you need the result. Require its read packet containing the resolved chain name and
ID, provider route, result, observed block or checkpoint, and coverage gaps.
If the chain is absent from evm-atlas, stop RPC-dependent work. Do not accept an arbitrary RPC URL to bypass that
restriction. When the chain is ambiguous, never infer Ethereum.
