BroadcastTransaction()

NODISCARD TransactionError BroadcastTransaction	(	NodeContext &	node,
		CTransactionRef	tx,
		std::string &	err_string,
		const CAmount &	max_tx_fee,
		bool	relay,
		bool	wait_callback
	)

Submit a transaction to the mempool and (optionally) relay it to all P2P peers.

Mempool submission can be synchronous (will await mempool entry notification over the CValidationInterface) or asynchronous (will submit and not wait for notification), depending on the value of wait_callback. wait_callback MUST NOT be set while cs_main, cs_mempool or cs_wallet are held to avoid deadlock.

Parameters

[in]	node	reference to node context
[in]	tx	the transaction to broadcast
[out]	err_string	reference to std::string to fill with error string if available
[in]	max_tx_fee	reject txs with fees higher than this (if 0, accept any fee)
[in]	relay	flag if both mempool insertion and p2p relay are requested
[in]	wait_callback	wait until callbacks have been processed to avoid stale result due to a sequentially RPC. return error

Variable Documentation

DEFAULT_MAX_RAW_TX_FEE_RATE

const CFeeRate DEFAULT_MAX_RAW_TX_FEE_RATE {COIN / 10}

static

Maximum fee rate for sendrawtransaction and testmempoolaccept RPC calls.

Also used by the GUI when broadcasting a completed PSBT. By default, a transaction with a fee rate higher than this will be rejected by these RPCs and the GUI. This can be overridden with the maxfeerate argument.
