How it works.
Every coin launched through Combo has a combo counter and a dev bag cut into 12 slices. Buyers build the combo together, any seller breaks it, and each combo goal burns a slice of the dev bag. Here it is step by step, then try it yourself below on the same engine the site runs.
Step by step
The dev launches and reserves
The dev buys at launch on pump.fun and reserves part of that buy, 50% by default and never less than 25%. The reserved part is cut into 12 slices, and the dev pre-signs a burn for each one.
Buys build the combo
A buy of at least 0.02% of supply, from a wallet that is not among the last 10 counted, adds one hit. Small buys and repeat wallets do nothing.
Sells break it
A sell of at least 0.02% of supply puts the combo back to zero. The seller is shown as the breaker, for everyone, forever.
Goals burn slices
A combo of 10 burns slices 1 to 4, 15 burns 5 to 8, 20 burns 9 to 12. Each burn uses the transaction the dev signed at launch.
The brake
At most one slice every 10 minutes, at most four in the first hour. A finished combo waits for the brake, and a sell during the wait still breaks it. If nothing burned after 30 minutes, slice 1 burns anyway.
The end
If the dev sells into the reserved part, every slice left turns VOID, in red. After 30 days, every slice left burns. Same trades, same result, for anyone who replays them.
Try it.
A made-up coin on the real engine: the dev bought 8% of supply and reserved half. Every button is one trade or a jump in time.
Launched. The combo is at zero; slice 1 needs 10 hits.
