An UpVote costs 3 dollars, paid in the chain's own coin, so the amount of BNB, SOL or ETH changes with the price. One transaction is one vote. The fee goes to MemeWarzone.
A battle Boost costs 1 dollar and adds 1 point. 90% of a Boost goes to the prize and 10% to MemeWarzone. A wallet can Boost twice per battle, and Boosts close in the last 20% of a battle.
