# Sending Transaction

### The routine for sending

A normal routine for sending a transaction is:

> Create -> Sign -> Broadcast -> (wait) -> Lookup and get receipt

Aixchain SDK defines the same protobufs include all RPC APIs and transaction related classes, also, Aixchain SDK wraps the functions in AixcClient.class.

#### An simple example

```java
  public static void sendTrx() 
  {        
  System.out.println("============= TRC transfer =============");
   AixcClient client = new AixcClient("172.104.51.182:16669","172.104.51.182:16669","private key");        
  try {            
  TransactionExtention transactionExtention = client.transfer("414203485a535a4072C9FBFaADDfe2A010AD0BcdB0", "41a9c46373aEB4749E3CE45acA242b027A46f486f9", 20_000_000);           
      Transaction signedTxn = client.signTransaction(transactionExtention);                       
      String ret = client.broadcastTransaction(signedTxn);            
      System.out.println("======== Result ========\n" + ret.toString());        
      } 
      catch (Exception e) {
    System.out.println("error: " + e);        
    }    
  }
```

**result**:

  public static void sendTrx() 

```

In Aixchain SDK, the routine is:

1. Create a **AixcClient** object with your private key.
2. Obtain a **TransactionExtention** object from  **AixcClient**.transfer().
3. Call **AixcClient.signTransaction()**&#x74;o sign the transaction with your private key binding with the **AixcClient** object.
4. Call **AixcClient`.`broadcastTransaction()** to broadcast the transaction and get a **TransactionReturn** for analysis.
