ref #13187

cc @hai-rise

further @hai-rise I think we can make this a reference:

reth/crates/transaction-pool/src/pool/txpool.rs

Lines 1181 to 1184 in c608679

	pub(crate) fn update(
	&mut self,
	changed_accounts: HashMap<SenderId, SenderInfo>,
	) -> Vec<PoolUpdate> {

and change the order

reth/crates/transaction-pool/src/pool/txpool.rs

Lines 465 to 468 in c608679

	// track changed accounts
	self.sender_info.extend(changed_senders.clone());
	// Apply the state changes to the total set of transactions which triggers sub-pool updates.
	let updates = self.all_transactions.update(changed_senders);

yep makes sense
