OK, so you opted in to RIO in the Algorand wallets. Can you send me the Algorand address, for which MEXC gives the error message?

(Address sent in private mail…)

OK. I looked up the address in [algoexplorer.io](http://algoexplorer.io)  
The problem is, that you haven’t opted in to asset RIO.  
Press the tab “Assets” beside “Transactions”, you will see that it is empty.  
Opt in to the required asset. Only after opt in can you receive it.

How to opt in? In the “usual” wallets like Pera Algo wallet there is a searate function for that:  
Assets Manage +  
Then you can sepcify asset id or asset name you want to opt in.

Opt in = adding asset to wallet

Try to add RIO in the Pera Algo wallet. You can download Pera from the Google Play Store.  
OR  
You can use Pera Algio web app, from here: [https://perawallet.app/](https://perawallet.app/)
