The short answers.

A single coin only has its own holders. A pair has a rival from the first block, and every trade on the other side still pays into the pot your side can win. People trade rivalries more than they trade anything else.

Because that is what gives the fight a reason. The program checks the type chart and refuses two types that are neutral in both directions, like Normal and Psychic. That leaves 77 pairs, and in most of them one type is favoured, which is why the underdog gets a bonus.

Each side scores by how far its SOL on the pump.fun curve rose during the round, averaged over time. Readings are taken every minute, and each gap between two readings counts at the lower of the two, so money only counts while it is actually there. The higher score, if it is above zero, gets the pot.

No. A buy only starts counting once it has survived to the next reading, and it only counts for as long as it stays. Buying big, taking a reading and selling adds nothing; the fork test does exactly that with 10 SOL and checks it moved the score by zero.

The winning side is owed it. Anyone can then trigger the buy: the pot buys that coin on its curve, or on PumpSwap once it has graduated, at most 2 SOL at a time, and burns every token it bought in the same instruction. A keeper does it automatically.

30% of both coins' creator fees, for as long as they trade. The other 70% is the pot. Pokepair takes nothing and has no admin key that could change that.

The first coin to fill its bonding curve wins the whole battle. Rounds stop, and from then on the pot and every fee from either coin is spent buying and burning the winner on its PumpSwap pool.

No. The program is unaudited and you should read it before sending anything. Nothing here is an investment or advice, and a coin that wins every round can still go to zero.
