The in-app shop allows users to purchase basic items like batteries. All purchases are made using $TADA tokens.
As described on the "economy" page, TADA coming from sales are redistributed to four buckets: the prize pool (65%), staking (5%), burning (5%), and the treasury (25%).
This means that the more purchases made in the shop, the larger the prize pool for users, the higher the APR for staking pools, and the greater the deflation. The initial version of the shop only offers batteries for purchase. Once additional items are implemented, the shop will offer new objects for sale, including some exclusive items.
