Yoroi Testnet Wallet
Well, it might be a noob question, sorry for that. After downloading Yoroi Testnet Wallet Firefox version) I was able to restore my wallet with 15 words (from Byron wallet) and new spending phase. I used option: restore wallet. I tried to stake a few times, but it didn’t work, wallet was pending all the time. Finally I had to switch to chrome version. I can stake now. But my question refers to something else: during the first recovery it took me 0.6 ADA as transaction fee. Shelley wallet has recorded the transaction (receive) with ADA from addresses I used to transfer my ADA from exchange to Byron wallet. During the process of recovery/creation of Shelley wallet Byron wallet was active. Is it ok, or ADA from Byron was transferred somehow? Balance on Byron Wallet (Firefox) is unaffected and all transactions are as they should be: transfers from exchange and nothing else.
