Live ERC-20 spending allowance an owner has granted a spender: calls `allowance(owner, spender)` on the token and returns the raw amount, a decimal-formatted amount (using the token's decimals) with its symbol, and an `isUnlimited` flag for effectively-infinite approvals. Use it to audit token approvals / approval risk before signing. Reads live on-chain data with automatic endpoint fallback.Overview
