If you already have a wallet, you can just go to www.alive.house, click the wallet icon next to your avatar on the top right of the screen and follow the instructions after selecting CONNECT METAMASK.
In order to complete transactions on a.live, you will also need to add the Polygon Network to MetaMask wallet. Here's how:
- Go to https://polygonscan.com/ and click 'Add Polygon Network' at the bottom of the site
- Click 'Approve' then 'Switch Network'
- Once you complete the steps above, you should see the 'Matic Mainnet' in your MetaMask dropdown menu in the browser extension and the dot next to 'Polygon' shown on our wallets page should now be green.
