there will be changes to speedy nodes in the near future:
Dear @cryptokid,
As far as I understand, we will be able to access the transactions that took place in the last 15 minutes from the speedy nodes paid and methods. Do I understand correctly?
I don’t understand the connection with what you want to do, you want the pending transactions
yes, it shows that with this new incoming upgrade, new methods are coming for pending transactions.
I don’t think now that getting the list of all pending transactions is something that we plan to support
