sendrawtransaction Method

Broadcasts transactions over the NEO network.

You must install the plugin RpcServer before you can invoke the method.

Parameter Description

transaction: A Base64-encoded string that has been serialized after the transaction signed in the program.

Example

Request body:

{
  "jsonrpc": "2.0",
  "method": "sendrawtransaction",
  "params": ["ALmNfAb4lqIAAAAAAAZREgAAAAAA8S8AAAEKo4e1Ppa3mJpjFDGgVt0fQKBC9gEAKQwFd29ybGQRwAwDcHV0DBR9rbALvBGpMrl7cXVBdSsPOC0EmUFifVtSAUIMQACXF48H1VRmI50ievPfC042rJgj7ZQ3Y4ff27abOpeclh+6KpsL6gWfZTAUyFOwdjkA7CWLM3HsovQeDQlI0oopDCEDzqPi+B8a+TUi0p7eTySh8L7erXKTOR0ziA9Uddl4eMkLQZVEDXg="],
  "id": 1
}

Response body in successful cases:

{
    "jsonrpc": "2.0",
    "id": 1,
    "result": {
        "hash": "0x13ccdb9f7eda95a24aa5a4841b24fed957fe7f1b944996cbc2e92a4fa4f1fa73"
    }
}

Response body in unsuccessful cases:

{
    "jsonrpc": "2.0",
    "id": 1,
    "error": {
        "code": -500,
        "message": "AlreadyExists"
    }
}

Response Description:

When result is false, the current transaction has failed to broadcast and an exception occurs. In this example, a confirmed transaction is broadcast, which fails due to the double cost.

The following error codes can be expected:

Error codes	Message	Description
500	AlreadyExists	Block or transaction already exists and cannot be sent repeatedly.
	OutOfMemory	The memory pool is full and no more transactions can be sent.
	UnableToVerify	The block cannot be validated.
	Invalid	The format or parameter is incorrect
	Expired	The block information is expired
	InsufficientFunds	Insufficient funds
	PolicyFail	The behavior is not allowed (such as blacklist address trading)
