sendrawtransaction

Send a raw transaction to the network and local node that is serialized and hex-encoded.

Because nodes typically won't rebroadcast non-wallet transactions that are already in their mempool, utilizing this for manual rebroadcasting may compromise privacy by disclosing the transaction's origin. Keep in mind that the transaction will be delivered unconditionally to all peers.
