 ### eth_sendRawTransaction
 
-Sends a signed transaction. A transaction can send ether, deploy a contract, or interact with a contract.  
+Sends a [signed transaction](../Using-Pantheon/Transactions.md). A transaction can send ether, deploy a contract, or interact with a contract.  
 
 You can interact with contracts using [eth_sendRawTransaction or eth_call](../Using-Pantheon/Transactions.md#eth_call-or-eth_sendrawtransaction).
 
-To avoid exposing your private key, create signed transactions offline and send the signed transaction data using this method. For information on creating signed transactions and using `eth_sendRawTransaction`, refer to [Using Pantheon](../Using-Pantheon/Transactions.md).  
+To avoid exposing your private key, create signed transactions offline and send the signed transaction data using `eth_sendRawTransaction`. 
 
 !!!important
     Pantheon does not implement [eth_sendTransaction](Using-JSON-RPC-API.md#account-management).
 
 **Parameters**
 
-`DATA` - Hash of the signed raw transaction in hexadecimal format; for example:
+`data` -  Signed transaction serialized to hexadecimal format. For example:

+!!! note
+    [Creating and Sending Transactions](../Using-Pantheon/Transactions.md) includes examples of creating signed transactions using the [web3.js](https://github.com/ethereum/web3.js/) library.
 
 **Returns**
 
-`result` : `DATA` - 32-byte transaction hash, or zero hash if the transaction is not yet available.
+`result` : `data` - 32-byte transaction hash
