# Combine (C)

### Combine (C):

Combine transactions are used to merge tokens from multiple UTXOs into a single UTXO.

* **Type**: D (Deploy)
* **Action**: C

### **Example OP\_RETURN Data**:

```mathematica
D C TOKEN_NAME
```

### **Role of UTXOs**:

* Each UTXO represents a specific amount of tokens.
* Multiple UTXOs are consumed from the sender's address to represent the combining of tokens.
* A single new UTXO is created with the combined total of the consumed UTXOs, encoded with a value of 0.01 DOGE.
* This simplifies the management of token amounts by consolidating multiple UTXOs into one.
* Each UTXO is connected to the token name and amount, ensuring the integrity of the combined token amount.

### Example Transaction Processing:

Combine Transaction

1. **Extract OP\_RETURN Data**: Decode the hex-encoded string to extract the token details.
2. **Validate Fields**: Ensure the token field is present.
3. **Combine UTXOs**: Merge multiple UTXOs into a single UTXO to simplify token amount management.
