There is no possibility to filter on a pending subscription transaction. I don’t want all pending transactions only ones sent to a specific address.
additionally from your documenttion:
newPendingTransactions - Returns the hash for all transactions that are added to the pending state and are signed with a key that is available in the node. When a transaction that was previously part of the canonical chain isn’t part of the new canonical chain after a reogranization its again emitted."
I want all pendingTransactions sent to a specific address, wether or not that were signed with a key available in the node.
Hope this makes sense.
