Custom creator fees, on‑chain.
Pick where the fees go before the coin exists. Launch on pump.fun, and every fee it earns gets routed the way you said it would.
Your coin's fees are already being spent.
You just don't know on what.
Every coin on pump.fun pays its creator a cut of every trade. Where that cut goes is decided afterwards, by one person, with nothing written down. It accrues quietly, one wallet claims it, and what happens next is whatever the creator says happened.
The damage is not the theft. It is that an honest launch and a dishonest one look identical at mint. Saying “fees go to buybacks” costs nothing and proves nothing. So decide first, and let the chain hold the receipt.
Launch
The mint is a pump.fun transaction. The split is a second one that says where the fees go, forever.
How it actually works
Three things worth knowing before you pick, because they decide what a split can and cannot be.
pump's fee sharing can only pay wallets
A shareholder is { address, share_bps }. It cannot call a program. So “burn” is not something the config can express — anything that is not a plain payout has to route to a wallet that then goes and does the work.
That single constraint decides the whole architecture, and every honest description of a fee-split launcher has to start there.
Your four-leg split will show one shareholder
Every leg that is not a direct payout collapses onto the executor address in the on-chain config. Four legs can appear as one shareholder in an explorer. It looks wrong the first time you check, and you should know that before you look rather than after.
Direct legs are enforced. Action legs are promises.
Creator and wallet legs are paid by pump directly, in the same transaction as the claim, and nothing anyone runs can interfere with them. Burn, holder rewards and jackpot are performed by a keeper wallet afterwards — auditable, because every transaction it makes is public, but not enforced by the chain.
The panel tells you which is which, in percent, before you sign. A split made only of direct legs needs no keeper at all.
Written once
pump's program marks the sharing config non-editable once the authority is given up. Read your split carefully before you sign, because that is the coin's policy for as long as the coin exists.
