	// This is only for in-wallet transaction
	const getTransaction = (txid) => new Promise((resolve, reject) => {
	client.gettransaction(txid, (err, r) => {
	if (err) {
	reject(new DashCoreRpcError(err.message, null, err.code));
	} else {
	resolve(r.result);

	client.gettransaction(txId, (err, r) => {
	if (err) {
	reject(new DashCoreRpcError(err.message, null, err.code));

	});
	});

Where is is this getting called? A masternode does not have an attached wallet, so calling this on an MN will return the empty set and an error. IMO these two methods should be removed.
