💸Value Transfer Events

Value Transfer Events are the smart contract functions that move ownership rights of deposited collateral between players.

Capital within existing positions are redistributed as part of a Value Transfer Event whenever players add or remove capital from a pool, where the winner’s profits p, is equal to the True Odds of their side of the pool o, multiplied by the percentage shift in the reference price since the last Value Transfer Event s, multiplied by their Mime’s position size m.

$$p = o*s*m$$

Conversely, a loser’s losses l, is equal to the percentage shift in the reference price since the last Value Transfer Event, multiplied by their Mime’s position size, without factoring True Odds at all.

$$l = s * m$$

Token Flow Illustration

The following chart illustrates how tokens might flow between two sides of a Pantomime at different Value Transfer Events.

In this example: Let’s assume for a given Pantomime that Alice represents all bulls who believe the reference price will rise, and Bob represents all bears who think the price will fall. And they are both using USDT. As you can see below, losers always lose at a 1:1 ratio of reference price movement, while winners earn at the rate of reference price movement relative to their True Odds.

	Reference Price % Change	True Odds	Alice (Long)	Bob (Short)	Value Transfer Event
Time 0	n/a	n/a	100	0	Alice opens a position
Time 1	n/a	0.5x vs. 2x	100	50	Bob opens a position
Time 2	50%	0.16x vs. 6.25x	125	20	Bob withdraws 5 USDT
Time 3	-50%	n/a	62.50	0	Bob withdraws 82.50 USDT
