# ERC-20 Input Call Data Generator
This Python script constructs input call data for transferring ERC-20 tokens using the `transfer(address,uint256)` function.
## Features
- Generates the input call data for the ERC-20 `transfer(address,uint256)` function.
- Encodes:
- The recipient's Ethereum address.
- The transfer amount in the smallest units of the token (e.g., 1 USDC = 10^6).
- Provides a reusable function (`construct_input_data`) for creating input call data for any ERC-20 token.
## Prerequisites
1. Python 3.12 or later installed.
2. Installed required Python dependencies.
## Installation
1. Clone this repository.
2. Install the required Python dependencies:
```bash
pip install -r requirements.txt
```
## Usage
1. Open the script file and ensure the recipient address and transfer amount are correct:
- **Recipient Address**: `0x85b931A32a0725Be14285B66f1a22178c672d69B` (PLACEHOLDER; Binance 10 account).
- **Transfer Amount**: `100 USDC` (PLACEHOLDER; represented as `100 * 10^6` in smallest units).
2. Run the script:
```bash
python eth-input-call-data-builder.py
```
3. The output will display the constructed input call data.
