You need a wallet (e.g. MetaMask) connected to Dogechain
Wait a few seconds
You can buy DEADHEADZ "on sale" for a fixed price of 10 WDOGE.
If you no longer love your DEADHEADZ, you can sell it at any time to the pool contract for a fixed price (100% mint cost) of 5 WDOGE.
Approve first and then sale.
