Fees
What traders pay
| Chain | Venue fee | Creator fee | Total |
|---|---|---|---|
| Solana | 0.95 % protocol | 0.30 % creator, fixed | 1.25 % |
| Robinhood Chain | 1 % curve fee | 0 to 10 %, Pons creator tax | 1 % to 11 % |
The Pons creator tax is set once at launch. The pump.fun creator fee is fixed by pump.fun.
Where creator fees go
On pump.fun. The creator fee goes to the coin's sharing config. Hinge sets it, once, to the creator's wallet and Hinge, 50 % each. After update_fee_shares_v2 the shares are locked by pump.fun itself, and each shareholder claims from pump.fun with their own wallet. The keeper cannot take the creator's share.
On Pons. The creator tax goes to the coin's HingeVault. split() is public:
| Share | Goes to |
|---|---|
creatorShareBps of the fees, at most 50 % | the creator's Robinhood address, if one was given |
| the rest | the Hinge address |
With no address given, all of it goes to Hinge.
How fees get collected on Pons
The Pons curve accumulates fees. sweepFees pushes them to the Pons fee escrow and the vault claims them with claim. collect() and split() do both and anyone can call them.
What a launch costs
| Amount | Paid by | |
|---|---|---|
| Pons launch fee | 0.0005 ETH | the creator's deposit, in ETH |
| Gas on Robinhood Chain | a few cents | the creator's deposit, in ETH |
| pump.fun creation | about 0.03 SOL | the keeper, repaid from the deposit at the current rate |
| Margin | 0.002 ETH | the creator's deposit |
Total: about 0.0045 ETH, a few ten dollars at most. Hinge charges no separate launch fee.
What Hinge earns
Only its share of the creator fees: half of the pump.fun creator fees and the part of the Pons creator tax that is not paid to the creator. $HINGE buybacks are not built yet.
