# Item.formatWithArgs

> Format a single ABI item with concrete argument values

## Overview

`Item.formatWithArgs` formats an ABI item by inserting argument values into the call string.

## Quick Start

```typescript theme={null}
import { Abi } from '@tevm/voltaire/Abi';

const transfer = {
  type: 'function',
  name: 'transfer',
  inputs: [
    { type: 'address', name: 'to' },
    { type: 'uint256', name: 'amount' }
  ]
} as const;

const formatted = Abi.Item.formatWithArgs(transfer, [
  '0x742d35Cc6634C0532925a3b844Bc9e7595f51e3e',
  1000n
]);
// "transfer(0x742d35Cc6634C0532925a3b844Bc9e7595f51e3e, 1000)"
```
