Upside USD · Upside Market Maker
The chart that climbs.
Every creator fee goes back into the chart. The UUSD Engine buys the dips, automatically, on chain.

How it works
A machine with one job: every fee the coin earns goes back into buying it.
-
1
You trade $UUSD. Every buy and sell on pump.fun pays a 0.3% creator fee.
-
2
The treasury fills. The engine collects those fees into its treasury every few minutes.
-
3
The engine buys the dips. When the price falls from its recent high, it buys at -5%, -10%, -15% and -25%, more at every step.
-
4
The floor rises. Sellers always meet a buyer. The engine keeps what it buys: it doesn't sell.
The exact rules
What the engine never does
- Spend anything but the coin's own creator fees.
- Sell the dev's tokens, or anyone's but its own.
- Sell at all: selling is switched off.
- Chase a pump: it buys dips, and small slices when the chart is calm.
Check it yourself
Every engine transaction is signed by the engine wallet and carries a memo:
UUSD engine buy 12 …. Its effect is the wallet's own balance change in that transaction, so the treasury above can be
recomputed from the chain by anyone.
Questions
Does the price only go up?
No. The engine buys dips with real fees, which makes every dip shallower and every recovery faster. It cannot stop a market that wants to sell: when the treasury is spent, it waits for more fees.
Where does the money come from?
Only from creator fees: pump.fun pays 0.3% of every trade to the coin's creator, which is the engine wallet. The engine spends that, nothing else. Busier trading means a bigger treasury.
Can someone game it?
Dips are measured on 1-minute closes, so a spike bought and dumped within the minute moves nothing. Buys are small slices (each moves the price by at most 1.5%), with a cooldown and an hourly budget, and the price is re-read from the chain right before every trade.
What happens at graduation?
When the bonding curve completes, the coin moves to PumpSwap. The engine follows it there automatically and keeps collecting and buying.
Is this financial advice?
No. Memecoins are extremely risky and can go to zero. Only use money you can afford to lose.
