duo.funOne coin. Two chains. Same second.
Every coin here is created on pump.fun and on PONS at the same opening market cap. A market maker, funded by the coin itself, keeps the two prices close whenever closing the gap pays for itself. Both caps, the live gap and every trade it makes are public.
Open pools chip in, share the fees
How it works
Created on pump.fun and PONS inside one second at the same opening cap, with the first buy inside the creation transaction on both chains. Nothing can be in front of it.
The dev's seed becomes the market maker. It sells the side that runs ahead and buys the side that lags, only when the gap is wider than the fees and impact of closing it. duo.fun never puts its money in.
Each page shows the band the maker holds right now, its cash, its inventory and every rebalance. Twine promised a number and bled defending it; we show the band and the money behind it.
2% creator tax on PONS, 0.3–0.95% on pump.fun. Half of every claim to duo.fun, half to the dev once the maker holds a small reserve. Every claim is listed with its transaction.
A coin with no trade on either chain for a full day is retired, with its numbers still on its page, and the maker's remaining seed goes back to whoever funded it.
The platform's coin. A fifth of what duo.fun earns buys $DUO and hands it to the $DUO maker as inventory, in public, listed here as it happens.
