I’m testing some code that replaces transactions.
I send a transaction with very low gas, and get a response back which gives me my transaction hash.
However, when I look for the hash on kovan, it’s not there.
When I then send another transaction, with the same nonce, and high gas, the transaction goes through as expected.
Does Infura hold back transactions, not broadcasting them to the mempool if they are low gas? If so, what is the threshold for this as I want to see my first transaction sitting in the pending state before I send my high gas transaction to replace it.
