Hi,

I am at the very last step of creating a stake pool where it says that only 3 keys need to be there  
( **kes.skey, vrf.skey, node.cert** ), however I also see deleg.cert, pool.cert and stake.cert.

In other words: on the screenshot attached below, do you see any file that should **not** be on the block-producer?

As always, your help is much appreciated. Thanks!

Hi!

Yes - put those cert files to your cold environment and you will be fine…
