sendrawtransaction

Submit a raw transaction (serialized, hex-encoded) to local node and network.

Note that the transaction will be sent unconditionally to all peers, so using this for manual rebroadcast may degrade privacy by leaking the transaction’s origin, as nodes will normally not rebroadcast non-wallet transactions already in their mempool.

Also see createrawtransaction and signrawtransactionwithkey calls.

Argument #1 - hexstring

Type: string, required

The hex string of the raw transaction

Argument #2 - maxfeerate

Type: numeric or string, optional, default=0.10

Reject transactions whose fee rate is higher than the specified value, expressed in BTC/kB.

Set to 0 to accept any fee rate.

Result

Name	Type	Description
hex	string	The transaction hash in hex

Examples

Create a transaction:

bitcoin-cli createrawtransaction "[{\"txid\" : \"mytxid\",\"vout\":0}]" "{\"myaddress\":0.01}"

Sign the transaction, and get back the hex:

bitcoin-cli signrawtransactionwithwallet "myhex"

Send the transaction (signed hex):

bitcoin-cli sendrawtransaction "signedhex"
