Help understanding transaction.

Hey guys, I’ve been mining RVN for a few months now. I was mining directly into my Binance wallet… a few days ago I had over 10k RVN and thought it would be safer in the RVN Wallet on my iOS device. I did a few small test transactions that were successful, so then I sent a large transaction of 10k… it showed up on my RVN wallet but was showing pending. This morning when I checked the wallet the transaction disappeared from my RVN wallet.
