Hi all, newbie here I am trying to send ETH from my Ledger Nano S to my Kraken account. This morning I sent a small amount of ETH and it arrived in my Kraken account within 10 Minutes. After this I tried to send a larger amount of ETH and it said successfully broadcast. However it has been 2 hours and is it still showing in my Ledger. I tried again with the same success message. Unfortunatelty the funds are still showing in my ledger and have not been sent. I have a few questions. Any help would be gratefully received. Why has it not sent? Do I need to use a higher gas limit when sending a larger amount? What should the Gas limit be? What is Gas Contract & can this be left blank? Thanks In advance.
