a second chance for every trader

Fumbled?
Undo it.

On a protected coin, part of every trade fills a pot. Once a day the pot pays back the people who bought the top or sold too early. No claiming, no wallet connect.

how undo works
1A coin gets protected 🛡

Its dev shares 25%+ of the pump.fun creator fees with undo. It's on-chain, anyone can check it.

2You trade like always

Axiom, GMGN, Phantom, pump.fun or a bot. undo reads every trade on-chain. Nothing to connect.

3You fumble

Undo Buy: you bought, then it fell 50%+. Undo Sell: you sold, then it ran 3×+. A dev dump or a rug counts too.

4You get paid back

Every day at 00:00 UTC the coin's pot is split between its fumblers, by the size of the fumble. SOL lands in your wallet.

Check a wallet

Every fumble undo has found for this wallet on protected coins, and what it was paid.

Protect your coin

Your coin stays on pump.fun. You share part of its creator fees with undo, and your holders get their fumbles paid back. Your coin gets the 🛡 badge and a shout from undo.

  1. Open your coin on pump.fun and turn on creator fee sharing.
  2. Add the undo wallet with 25% or more:
  3. Paste your coin's address below. undo checks the share on-chain and starts right away.
  4. Optional: lock the sharing on pump.fun for the 🛡 permanent badge.

20% of what undo receives buys back $UNDO and burns it. The rest is your coin's pot and only pays your coin's holders.
