The main page of your Koala Wallet shows a summary of your portfolio, with only the total dollar portfolio value, individual asset balances and their respective equivalent dollar value. To see specific transactions and details, tap the asset you want to check.
Inside a specific asset's wallet you'll find the "Transactions" tab listing all of its transactions. You can see if you sent it from your wallet or if it was received into it, as well as the other address involved, asset amount and transaction date. You can also filter the list to show only received, sent and failed transactions, or show only transactions in a specific chain.
By tapping an item of the list, you will see the transaction's complete details. It includes the full address involved, source and destination chains, number of confirmations and the transaction ID.
