A web based interface to the Bitcoin API JSON-RPC

Command: sendrawtransaction

The sendrawtransaction RPC validates a transaction and broadcasts it to the peer-to-peer network.

Parameter #1—a serialized transaction to broadcast
Parameter #2–whether to allow high fees
Result—a TXID or error message

The serialized transaction to broadcast encoded as hex.
Set to true to allow the transaction to pay a high transaction fee. Set to false (the default) to prevent Bitcoin 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.
null
