sendrawtransaction "hexstring" ( maxfeerate maxburnamount )
Submit a raw transaction (serialized, hex-encoded) to the network.
If -privatebroadcast is disabled, then the transaction will be put into the
local mempool of the node and will be sent unconditionally to all currently
connected peers, so using sendrawtransaction for manual rebroadcast will degrade
privacy by leaking the transaction's origin, as nodes will normally not
rebroadcast non-wallet transactions already in their mempool.
If -privatebroadcast is enabled, then the transaction will be sent only via
dedicated, short-lived connections to Tor or I2P peers or IPv4/IPv6 peers
via the Tor network. This conceals the transaction's origin. The transaction
will only enter the local mempool when it is received back from the network.
A specific exception, RPC_TRANSACTION_ALREADY_IN_UTXO_SET, may throw if the transaction cannot be added to the mempool.

Arguments:
1. hexstring (string, required) The hex string of the raw transaction
2. maxfeerate (numeric or string, optional, default="0.10") Reject transactions whose fee rate is higher than the specified value, expressed in BTC/kvB.
Fee rates larger than 1BTC/kvB are rejected.
Set to 0 to accept any fee rate.
3. maxburnamount (numeric or string, optional, default="0.00") Reject transactions with provably unspendable outputs (e.g. 'datacarrier' outputs that use the OP_RETURN opcode) greater than the specified value, expressed in BTC.
If burning funds through unspendable outputs is desired, increase this value.
This check is based on heuristics and does not guarantee spendability of outputs.
Result:
"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"
