I want to send raw transactions but I don't want to accidentally overwrite any transactions.
Afaik when using eth.sendTransaction it automatically increments the nonce and doesn't overwrite any transactions (is the node keeping track of the nonce here?). Now I have a script that sends raw transactions to a node (no account listed there for security reasons, obviously).
Is there a way to automatically append transactions without knowing the nonce or accidentally overwriting transactions? Or do I have to keep track of the nonce myself?
