* **Bulk Processing**: Supports 100+ addresses via CSV upload
* **Multi-Asset Support**: ETH & ERC-20 tokens
  {% endhint %}

***

## **Setup Guide**

### **1. Configure Transfer Parameters**

**a) Select Asset**

* ETH (default)
* ERC-20 (paste contract address)

**b) Set Amount per Transfer**

text

```
Example: 0.005 ETH → each sender-recipient pair moves this amount  
```

**c) Execution Interval** *(Optional)*

text

```
5-60 seconds recommended to avoid clustering  
```

***

### **2. Import Addresses**

**Sender Wallets** *(Requires private keys)*

text

```
0xPRIVATEKEY1  
0xPRIVATEKEY2  
```

*(Or upload CSV/TXT file)*

**Recipient Wallets** *(Addresses only)*

text

```
0xADDRESS1  
0xADDRESS2  
```

*(Or upload CSV/TXT file)*

>  **All keys processed locally** — Never stored or transmitted
