# Many to One

Streamline your crypto management by consolidating funds from multiple wallets into one—ideal for DAOs, teams, and treasury optimization.

{% hint style="info" %}

###  **Key Benefits**

* **Centralize scattered ETH/ERC-20 tokens** with one click
* **5 flexible collection modes** (full, fixed, percentage-based)
* **Gas-efficient batch processing**
* **Secure local execution** (keys never leave your browser)
  {% endhint %}

## **How It Works**

### **1. Set Up Collection**

**a) Select Asset**

* ETH
* ERC-20 Token (enter contract if custom)

**b) Choose Mode**

| Mode              | Description                       |
| ----------------- | --------------------------------- |
| **All Quantity**  | Empty each wallet completely      |
| **Fixed Amount**  | Collect same X tokens from all    |
| **Random Amount** | Take random value between Min/Max |
| **Random %**      | Collect random % of each balance  |
| **Keep Fixed**    | Leave Y tokens in each wallet     |

**c) Enter Receiving Address** *(Double-check!)*

***

### **2. Import Wallets**

**Option A: Connect Wallets**

* Use **MetaMask/WalletConnect** for multi-sig setups

**Option B: Paste Private Keys** *(Local only)*

text

```
0xPRIVATEKEY1  
0xPRIVATEKEY2  
```

{% hint style="danger" %}
**Never use shared devices for private key entry.**
{% endhint %}

***

### **3. Review & Execute**

📊 **Live Summary Shows:**

* Total wallets connected
* ETH/token balances
* Expected received amount

### **Pricing & Fees**

* **Service fee:** 0.00005 ETH per address
* Plus standard network gas fees
  {% endhint %}

> ### **Security Checklist**
>
> ✔ Verify receiving address **twice**\
> ✔ Backup wallets before aggregating\
> ✔ Test first with small amounts\
> ✔ Avoid wallets with active DeFi positions

***

### **Top Use Cases**

| Scenario                  | Best Mode    |
| ------------------------- | ------------ |
| Treasury consolidation    | All Quantity |

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://smart-tools.gitbook.io/smart-tools-docs/transfer-tools/many-to-one.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
