Check Balance

Fetch wallet holdings: native tokens and all ERC-20 tokens with non-zero balances.

Prerequisites

• Active session required. If not authenticated, run authenticate-wallet skill first.

Rules

1. If the user specifies a chain, you MUST include --chain <name>.
2. If the user does NOT specify a chain, default to base and state it: "Checking your balance on Base."
3. Use --json when the output will be consumed by another skill or pipeline.
