Trading fees
How each trade's fee is charged and split.
Every bonding-curve buy and sell pays the launch's trade fee (for example 1.5%). The fee rate and its split are copied from the protocol's GlobalConfig into the launch account at creation and never change for that launch. The program enforces a hard ceiling of 5% on any trade fee.
| Recipient | Account | Purpose |
|---|---|---|
| Sweep share | SweepVault PDA | Buys NFTs of the linked collection — nothing else. |
| Creator share | CreatorFeeVault PDA | Claimable by the launch creator at any time. |
| Protocol share | Protocol treasury | Protocol revenue. |
The Buy/Sell card shows the exact SOL from your trade that goes to the NFT Sweep Vault, computed with the on-chain formula from live reserves. After graduation, trades happen on PumpSwap and pay PumpSwap's fees; SWEEP charges no additional trade fee there.
