02 · Random batches
Five rugs. Three runners. Two dead. You won't know which.
You don't pick the coin. You set the rules: narratives, how far they ran, how many died, how many rugged. Rewind draws real launches that match at random, and you only find out which coin you got when its chart starts. Odds are you've never seen it, so you trade it like it's live.
Narratives every narrative
Outcome mix what really happened to the coins you get
Each coin comes with the post it launched on, timed to the second. Dev buys and sells, whale entries, KOL wallets and the migration show up on the tape as they happen, with names and pictures. You get the same information the trenches had, in the same order.
Your orders fill against the bonding curve at the price when they land, so size, speed and fees cost what they cost on-chain. Pick how much the market punishes you.

08 · FAQ
Questions.
Is this real data?
Yes. Every coin is a real pump.fun launch. Rewind records its trades from the first second: time, side, size in SOL, market cap and wallet. The replay applies them in order, so the chart, the tape and the holder count are the ones the trenches saw.
How do my orders fill?
Against the bonding curve, or the pool after migration, at the price when your order lands. Fees, priority fee and the fill delay come from your difficulty. Big orders pay real curve slippage. Your paper orders never move the recorded market.
Can I replay any coin?
Paste any pump.fun contract address. Coins in the library load instantly. Any other coin is fetched from launch and cached for the next player.
Won't I just remember the coin?
You don't choose it. Rewind draws it at random from the launches that match your rules, and you only see which coin you got when its chart starts. Most launches are coins nobody remembers, so the chart, the tape and the post land on you the way they landed on the trenches. If you do recognise one, hit next and draw again.
What does my wallet sign?
One plain-text message with your score and the coins you played, only when you post a ranked score. No transaction, no token approval. Guests can play everything else without connecting.
Is this financial advice?
No. Rewind is paper trading on recorded market data. Past launches don't predict future ones.
