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.
