A Cumble is a pump.fun coin with permanent rules for the coins launched under it. You choose the fee split and who can launch. Each new coin inherits those terms.
Before you start
Have your artwork and a Solana wallet ready. On mobile, open Cumble inside your wallet app. Keep SOL for the 1 SOL creation fee plus about 0.0115 SOL of network fees and rent for the new accounts.

Choose a launchpad kindLink to Choose a launchpad kind
Every Cumble has one kind, chosen at creation.
- Direct payout: creator fees are distributed to holders of the Cumble token each round.
- Burn: creator fees buy back the Cumble token and burn it each round.
Understand creator feesLink to Understand creator fees
pump.fun pays a creator fee on every trade. On Cumble, that fee is sent to a program vault instead of a personal wallet, and is split by the rule you chose.
Know what is permanentLink to Know what is permanent
Rules are frozen on chain so launchers and holders can trust them.
- The kind and fee split can never change.
- Launch access can only be loosened, never tightened.
- Artwork and metadata follow pump.fun rules.
Follow rewards and roundsLink to Follow rewards and rounds
Fees accumulate in the vault and settle in rounds. Each settled round shows on the Rounds page with its payout or burn amount and a link to the transaction.
Check launch accessLink to Check launch access
A Cumble can be open to everyone or limited to allowlisted wallets. The Cumble page shows which one applies before you try to launch.
Resolve common issuesLink to Resolve common issues
Most failed transactions come from a few causes.
- Not enough SOL for fees and rent. Top up and try again.
- Wallet not on the allowlist for a restricted Cumble.
- Network congestion. Wait a moment and retry with the same details.
