# TheButton Wrapped AZERO

Few months ago, in 2023, we've deployed a game called **TheButton** (<https://the-button.azero.dev/>). The game allowed users to play, and earn rewards token, but for that it was necessary to hold some wrapped AZERO (`wAZERO`) in the wallet. For that purpose a special contract was deployed.

Since then we've worked hard on Common AMM and finalised the new, latest version of wrapped AZERO - <https://github.com/Cardinal-Cryptography/wAZERO>.&#x20;

That new contract is being used in Common AMM - which means if you hold `wAZERO` from **TheButton,** you won't be able to use with Common.

To fix this situation, you first need to unwrap **TheButton** `wAZERO`.

Step 1. Go to <https://the-button.azero.dev/exchange> and connect your wallet.

Step 2. Select `wAZERO` as the token you're selling and `AZERO` as the token you want to buy.

Step 3. Specify the amount of `wAZERO` tokens you want to sell.

Step 4. Click Swap and sign the transaction.

et voila - you've successfully unwrapped your `wAZERO` back to `AZERO`.

Step 5. Go to Common AMM and use your native `AZERO`.
