ColosseumThe house
never empties.
Every trade pays a one percent toll in USDG. Half raises the row behind every seat. Half is scattered to the stands in USDG. Exits burn seats, and the row rises again.
Light scale. Lit height = row ÷ (row + 0.10 USDG/seat). A permanent scale, never rescaled — a tier that has lit stays lit. It is not how much of the reserve is left, and not a projection.
Take a seat.
Be paid in USDG.
At the games, gifts were scattered into the stands. Here half of every toll is paid to the seats that are enrolled — in real USDG, streamed over eight-hour epochs. Nothing is printed to pay it, and no seat is locked.
Connect a wallet holding ARENA to take a seat.
Burn seats.
Receive USDG.
The house buys your seats back just under the row, then destroys them. Every exit raises the row for everyone still inside.

Five pieces.
No discretion.
Every claim on this page is a line of a contract, not a promise.
10,000 seats at creation
ARENA is minted once, in the constructor, and never again. There is no minter to renounce, because there is no mint function. The only thing that changes the supply is a holder burning their own seats.
The tessera
Every trade pays a one percent toll, in all four swap shapes. Half goes to the cavea, half to the sparsio. The pool's own trading fee is separate and belongs to the position that opened it.
The row
The cavea's USDG per seat outstanding. It is stored, and one line writes it, guarded by a strict greater-than. No function lowers it and no caller passes a value in.
The sparsio
The dividend. Seats enrolled in the stands are paid their share of the toll in USDG, streamed over eight-hour epochs. Nothing is printed: the income is money, not dilution.
The vomitorium
The exit. One percent under the row, every seat taken is burned, capacity one percent of the reserve per hour with no rollover.
What this is not
The row rising does not mean the market price cannot fall. The pool price is set by trading and can sit above or below the row. The row is a floor you can exit into, within the hourly capacity — not a guarantee of value.

What the house did.
Tolls seated in the cavea, dividends collected, seats burned on the way out, and every time the row rose.
Nothing yet. The house opens when the pool does.
