Pawn is a really cool feature, i think some stuff could be implemented (just my personal ideas, that could be further thought thru):
idea1:
Pawn vaccum mode:
you can only pawn if floor price is above 0.8 eth or it is below 0.4 eth, this way, people dont over pawn (reduced incentives) keeps good floor since below 0.4 eth is like free money to buy pawn and sell higher (marketmaking).
idea2:
Pawn max degen:
the more you pawn, the more eth you win each pawn. incentivise people to pawn and trade, bringing more volume both sides.
idea3:
Pawn Debt fee staking:
the more time your wassie is pawned, the more fee's you need to pay, for a limited but reasonable amount of time (3 years). This way pawners don't get rekt so often by needing to unpawn to sell to pay for other unpawning/extentions, they have enough time for a new market cycle and time to plan their trades.
