The LP and the payout queue
What Papertrade traders are trading against, where the LP balance comes from and what happens when a winning payout cannot be paid immediately.
The Papertrade LP
The LP starts without a conventional seeded pool and grows through cumulative protocol trading economics. It is not a public deposit vault.
The payout queue
If LP reserves are insufficient for the profit portion of a winning close, the unpaid amount can enter a FIFO payout queue and is serviced as solvency returns.
What is and is not queued
The documentation distinguishes winning profit from user margin. Margin is returned to available balance on close; only unpaid profit can wait in the payout queue.
What this means for traders
A solvent winning close pays immediately. An underfunded profit becomes onchain debt awaiting queue harvest rather than being permanently haircut.
PAPER emissions are designed to be strongest while the LP is small or underwater.
