If you have just created a wallet at https://raidowallet.com/login and have not yet made any transactions, you will not be able to find your wallet on Raidoscan
That happens because you did not generate any transactions yet, in other words, you wallet was not involved in the block creation.
To have information about your wallet displayed on Raidoscan, make at least one transaction. For example, you can buy RDO for cryptocurrency or via bank card at Fast exchange.
Then transfer RDO from your Raidofinance wallet to your RDO wallet . This transaction will appear as "Received RDO" in your Transactions section
Now copy your RDO wallet and paste it in the Raidoscan and voila, your wallet has been found. You may check the current balance and the last transactions on your wallet.
