Raw Transaction RPCs
CombineRawTransaction
The combinerawtransaction
RPC combine multiple partially signed transactions into one transaction.
The combined transaction may be another partially signed transaction or a
fully signed transaction.
Parameter #1---txs
Name | Type | Presence | Description |
---|---|---|---|
txs | string | Required | A json array of hex strings of partially signed transactions |
Result---hex-encoded raw transaction with signature(s)
Name | Type | Presence | Description |
---|---|---|---|
result | string | Required (Exactly 1) | The resulting raw transaction in serialized transaction format encoded as hex. |
Example from Dash Core 0.15.0
The following example shows a fully signed two input transaction being assembled
by combining two partially signed transactions. The first hex-encoded string is
the transaction with only the first input signed. The second hex-encoded string is
the transaction with only the second input signed.

FundRawTransaction
Requires wallet support (unavailable on masternodes).
The fundrawtransaction
RPC adds inputs to a transaction until it has enough in value to meet its out value. This will not modify existing inputs, and will add one change output to the outputs.
Note that inputs which were signed may need to be resigned after completion since in/outputs have been added. The inputs added will not be signed, use signrawtransaction for that.
All existing inputs must have their previous output transaction be in the wallet.
Parameter #1---The hex string of the raw transaction
Name | Type | Presence | Description |
---|---|---|---|
Hex string | string (hex) | Required (exactly 1) | The hex string of the raw transaction |

.

- CreateRawTransaction: creates an unsigned serialized transaction that spends a previous output to a new output with a P2PKH or P2SH address. The transaction is not stored in the wallet or transmitted to the network.
- DecodeRawTransaction: decodes a serialized transaction hex string into a JSON object describing the transaction.
- SignRawTransaction: signs a transaction in the serialized transaction format using private keys stored in the wallet or provided in the call.
- SignRawTransactionWithKey: signs inputs for a transaction in the serialized transaction format using private keys provided in the call.
- SendRawTransaction: validates a transaction and broadcasts it to the peer-to-peer network.

GetRawTransaction
The getrawtransaction
RPC gets a hex-encoded serialized transaction or a JSON object describing the transaction. By default, Dash Core only stores complete transaction data for UTXOs and your own transactions, so the RPC may fail on historic transactions unless you use the non-default txindex=1
in your Dash Core startup settings.
Note: By default this function only works for mempool transactions. When called with a blockhash argument, getrawtransaction will return the transaction if the specified block is available and the transaction is found in that block. When called without a blockhash argument, getrawtransaction will return the transaction if it is in the mempool, or if -txindex is enabled and the transaction is in a block in the blockchain.
Reindex note
If you begin using
txindex=1
after downloading the block chain, you must rebuild your indexes by starting Dash Core with the option-reindex
. This may take several hours to complete, during which time your node will not process new blocks or transactions. This reindex only needs to be done once.

Name | Type | Presence | Description |

TXID | string (hex) | Required (exactly 1) | The TXID of the transaction to get, encoded as hex in RPC byte order |

---|---|---|---|
Block Hash | bool | Optional (0 or 1) | Added in Dash Core 0.16.0 The hash of the block in which to look for the transaction |
Result (if transaction not found)---null
Name | Type | Presence | Description |
---|---|---|---|
result | null | Required (exactly 1) | If the transaction wasn't found, the result will be JSON null . This can occur because the transaction doesn't exist in the block chain or memory pool, or because it isn't part of the transaction index. See the Dash Core -help entry for -txindex |

SendRawTransaction
The sendrawtransaction
RPC validates a transaction and broadcasts it to the peer-to-peer network.
Parameter #1---a serialized transaction to broadcast
Name | Type | Presence | Description |
---|---|---|---|
Transaction | string (hex) | Required (exactly 1) | The serialized transaction to broadcast encoded as hex |
Parameter #2--whether to allow high fees
Name | Type | Presence | Description |
---|---|---|---|
Allow High Fees | bool | Optional (0 or 1) | Set to true to allow the transaction to pay a high transaction fee. Set to false (the default) to prevent Dash Core from broadcasting the transaction if it includes a high fee. Transaction fees are the sum of the inputs minus the sum of the outputs, so this high fees check helps ensures user including a change address to return most of the difference back to themselves |
Parameter #3--whether to use InstantSend
Name | Type | Presence | Description |
---|---|---|---|
Use InstantSend | bool | Optional (0 or 1) | Deprecated and ignored since Dash Core 0.15.0 |
Parameter #4--whether to bypass policy limits
Name | Type | Presence | Description |
---|---|---|---|
Bypass Limits | bool | Optional (0 or 1) | Bypass transaction policy limits |
Result---a TXID or error message
Name | Type | Presence | Description |
---|---|---|---|
result | null/string (hex) | Required (exactly 1) | If the transaction was accepted by the node for broadcast, this will be the TXID of the transaction encoded as hex in RPC byte order. If the transaction was rejected by the node, this will set to null , the JSON-RPC error field will be set to a code, and the JSON-RPC message field may contain an informative error message |
Examples from Dash Core 0.12.2
Broadcast a signed transaction:
dash-cli -testnet sendrawtransaction 01000000016b490886c0198b\
