Creator fee economics
90% of creator fees to the sers, 10% to SER to buy and burn $SER: what the split covers and how it works on pump.fun (Solana, in SOL) and pons (Robinhood Chain, in ETH), with worked examples.

The short version
90% TO SERS. 10% TO SER. SER BUYS SER. SER BURNS SER.
The model in full, with a SOL and an ETH example
Every coin launched through SER puts its creator fees through one split: 90% to the sers, as the coin’s reward pool, and 10% to SER, which uses it to buy $SER and burn it. The split is the same on both launchpads SER supports. How it is enforced is not, so this page shows each side by side: pump.fun on Solana and pons on Robinhood Chain.
This is SER’s default and only public model. There is no other SER fee: nothing skims the 90%, and any future operating revenue would be documented separately before it exists.
On Solana (pump.fun)
SOLWorked example
A coin’s creator fees add up to 1 SOL and pump.fun distributes them.
0.9 SOL goes to the reward wallet for sers. 0.1 SOL goes to SER’s buyback treasury. Each share is rounded down to a whole lamport; dust stays in pump.fun’s vault for the next distribution.
On Robinhood Chain (pons)
ETHWorked example
A token’s SER fee router claims 0.1 ETH of creator-side fees from pons.
0.09 ETH goes to the SER reward vault, as WETH. 0.01 ETH goes to the buyback treasury. The SER share is rounded down, so any rounding remainder goes to the sers.

What counts as creator fees on each chain
Creator fees only. The split applies to the creator’s share of trading fees — never to the launchpad’s own fee, and never to the price traders pay for anything else.
On Solana (pump.fun)
SOL- The coin’s pump.fun creator fee, on the bonding curve and after graduation.
- Paid in the coin’s pair token — SOL by default. A coin paired with another token pays its fees, and its rewards, in that token.
- pump.fun’s own fee is unaffected and never reaches SER.
On Robinhood Chain (pons)
ETH- The part of every trade’s fees that pons pays to the token’s creator-fee recipient — plus any creator fee the creator set at launch. For SER launches that recipient is the token’s SER fee router.
- Every asset: the router splits native ETH, the pair token and any launch tokens pons vests to the recipient. The sers’ ETH share reaches the reward vault as WETH — wrapping is one-to-one, not a swap.
- pons’ own protocol share is unaffected. It never reaches the router; the split applies only to the creator-side fee allocation available through pons.

How the creator fee works on each chain
Where a launchpad lets the creator set their own fee, SER shows a slider for it on new launches. It is separate from the 90/10 split: the split decides where creator fees go, the creator fee decides how much traders pay.
On Solana (pump.fun)
SOLOn coins paired with SOL, the creator fee is set by pump.fun and can’t be adjusted, so SER shows no slider. SER does not set that rate and does not promise one; pump.fun can change it.
pump.fun lets the creator choose a fee only on certain other pairs. Where SER offers such a pair, the slider shows pump.fun’s own limits and rules, read from Solana.
On Robinhood Chain (pons)
ETH- The creator can add a fee at launch. Traders pay it on every buy and every sell, on top of pons’ base trading fee. The default is 0%.
- The maximum is set by pons and read from its contracts when you launch. SER does not set it and cannot raise it.
- pons fixes the fee in the token at launch. Nobody can change it afterwards.
- pons takes no protocol share of it: all of it reaches the token’s SER fee router and is split 90/10 like every other creator-side fee.
A higher fee means a bigger reward pool per trade, and a coin that costs more to trade. Each coin’s page shows its fee.

Each step, and what pump.fun can change
There is no SER contract on Solana. The launch transaction sets pump.fun’s own fee sharing for the coin — 90% to the reward wallet for sers, 10% to SER’s buyback treasury — and gives up the right to change it in the same step. After the launch confirms, SER reads the coin’s fee-sharing config back from Solana, and only says the fees are routed when it is exactly that split, and locked.
- 01
Fees accrue on pump.fun
Trades credit the coin’s creator fee to its creator vault, in the pair token (SOL by default). - 02
Anyone can distribute
pump.fun’s distribution is permissionless; SER’s keeper calls it on a schedule. pump.fun pays the two recipients directly — the funds never pass through a SER contract. - 03
SER indexes each payout
Every distribution is recorded with its asset, the amount to the reward wallet and the amount to the buyback treasury, and its transaction. - 04
Rewards
Rewards are allocated to sers who saved a Solana address, but payouts are not live yet: an allocation is not a payment.
- Creator fees, and the rewards funded by them, are paid in the coin’s pair token — SOL by default. Amounts in different assets are never added together.
- The buyback from SER’s share is not live on Solana yet: the 10% accumulates in the buyback treasury wallet.
- pump.fun’s admin can reassign a coin’s creator or reset its fee split without notice. SER watches for it and pauses that coin’s rewards if it happens.

Each step in detail
- 01
Fees accrue on pons
Trades credit creator-side fees to the token’s SER fee router in the pons fee escrow. Credits land when pons sweeps fees, which can lag trading. - 02
Anyone can claim
The router’s harvest function is permissionless; SER’s operator calls it on a schedule. It claims ETH, the pair token and vested launch tokens. - 03
The router splits
Each asset is split by the router’s fixed policy. The SER share is rounded down, so any rounding remainder goes to the sers. - 04
Delivery
The sers’ share goes to the SER reward vault; the SER share goes to the buyback treasury. If the treasury can’t accept it, the router holds that amount and retries on the next distribution — it is never split twice. - 05
Every step is an event
CreatorFeesReceived, RewardAllocationCreated and ProtocolFeeAllocated are emitted per asset, so every amount reconciles onchain.
- 10% shareaccumulates
- Buys $SERonce $SER is live
- Burns itsame transaction
- Buybacks start once $SER is live
Not price support
Buybacks and burns reduce the supply of $SER. They are not a promise about its price, and nothing here is investment advice.
Where the 10% is on each chain, and how a buyback runs
On Solana (pump.fun)
SOLThe 10% share arrives at SER’s buyback treasury wallet on Solana, in each coin’s pair token. The buyback is not live on Solana yet: nothing moves that share, and it is accounted per asset from the indexed distributions.
On Robinhood Chain (pons)
ETHThe 10% share accumulates in the SER buyback treasury contract. Once $SER is live and the treasury holds enough to execute, SER’s keeper buys $SER through an approved swap router — and the treasury burns every $SER it bought in the same transaction.
- Buybacks start once $SER is live. Until then the treasury only accumulates, and on Robinhood Chain its funds can only ever leave through a buyback.
- Bought $SER goes to the burn address
0x000000000000000000000000000000000000dEaD. Each buyback emits BuybackExecuted (amount spent, $SER bought, price) and SERBurned. - $SER that reaches the treasury directly — for example $SER’s own creator fees — can be burned by anyone.
- Buybacks run when the treasury balance reaches a threshold and enough time has passed since the last one. Each trade has a maximum size and a minimum $SER output.
Treasury safeguards
These apply to the buyback treasury contract on Robinhood Chain. On Solana the treasury is a plain wallet until a buyback exists there.
- Fee assets can’t be withdrawn. The only way out is a buyback.
- Buybacks use approved swap routers only, with per-asset minimum and maximum trade sizes.
- Every buyback sets a minimum $SER output above zero and checks the amounts actually spent and received.
- A guardian can pause buybacks; only the admin multisig can unpause them.
- Tokens sent to the treasury by mistake can be rescued only if they were never received as fees and are not $SER.
Policy and governance
On Solana (pump.fun)
SOL- The split is written into pump.fun’s fee sharing once per coin, in the launch transaction, and locked. SER cannot change it for an existing coin.
- The split for new launches is SER’s published policy. You acknowledge the exact split before launching, and SER only sends a launch whose split still equals it.
On Robinhood Chain (pons)
ETH- The split is enforced onchain by the SER fee router factory. Each router copies the policy when it is created and keeps it for life, so a later change never touches existing routers.
- Changing the policy for new routers requires the factory’s admin role, held by a multisig behind a transfer delay. The change emits EconomicPolicyUpdated and is recorded in SER’s admin audit log.
- The two shares always add up to 100%, and the SER share can never exceed 50%.
- SER’s admin console can only record a governance request. It cannot change routing.
Launchpad override powers
Each launchpad keeps a power over a coin’s creator fees that SER cannot remove. SER indexes it, alerts its admins and says so on the coin’s page.
On Solana (pump.fun)
SOLpump.fun’s admin can reassign a coin’s creator or reset its fee split without notice. If that happens, SER pauses the coin’s rewards and shows a warning on its page. Funds that already reached the reward wallet are not affected.
On Robinhood Chain (pons)
ETHFor pons v2 tokens, the pons owner (a multisig) can override a token’s creator-fee recipient after a 3-day timelock. SER shows a notice on the token page while one is pending. Rewards already published can still be claimed.
Where to verify
- SER economics shows total creator fees, the amounts sent to the sers and to SER, $SER bought and burned, the treasury balance, and every buyback with its transaction — and, for Solana, the same books per asset.
- Each coin’s page shows its creator-fee routing: the locked split and its transactions on Solana, the Creator Fee Routing card and any pending override on Robinhood Chain.
- Every figure is a sum of indexed onchain events — never an estimate — and SOL and ETH amounts are shown in their own units, never converted or added.
- How the sers’ share is paid out: SER rewards.
