Transfer Reddit Avatar to Brave Wallet Ethereum Adress.

I just want to transfer my Avatar to an other Wallet. I make a Wallet by Brave. I have sending the Avatar via transfer to the Ethereum Blockchain Adress. Now the Avatar is away from Reddit, but it is not arrived at my Brave Wallet. Was this the wrong Blockchain? And how can I get my avatar back? I have not so much experience with crypto and wallets. It was my first try to handle with crypto. I dont find any way in the reddit app or in brave wallet. In the case it was the wrong network, why to the hell it is not more in my wallet? Where is the Coin?
