Fees & payouts
What traders pay
Section titled “What traders pay”| Charge | Current setting |
|---|---|
| Curve buy fee | 1% of gross input |
| Curve sell fee | 1% of gross quote proceeds |
| Creator tax | Creator-selected, 0–10%; fixed per launch |
| Anti-snipe tax | Early buys only; decays over the launch’s selected window |
| Graduated pool | 1% current base hook fee, plus that launch’s creator tax; LP fee is zero |
| Network gas | Separate, paid in native USDC |
Base curve buy/sell fees have a 5% configuration cap. The regular base-fee-plus-creator-tax ceiling is 20%; the additional anti-snipe tax has its own cap. These hard limits are not the rates charged by every token. Read the launch and pool settings.
Where the base fee goes
Section titled “Where the base fee goes”The current split takes 30% of the base-fee bucket for the protocol. If buybacks are enabled, 50% of the remaining 70% is reserved for buybacks. The creator receives the remainder plus all creator tax.
For a 100-USDC curve buy, outside the anti-snipe window, with zero creator tax:
| Destination | Buybacks on | Buybacks off |
|---|---|---|
| Curve reserve | 99 USDC | 99 USDC |
| Protocol | 0.30 USDC | 0.30 USDC |
| Buyback funding | 0.35 USDC | 0 USDC |
| Creator fee balance | 0.35 USDC | 0.70 USDC |
If the creator tax is 2%, another 2 USDC goes to the creator and only 97 USDC enters the curve. Early-buy anti-snipe tax joins the shared fee bucket; it is not burned.
Accrual is not an instant payout
Section titled “Accrual is not an instant payout”Curve fees accumulate in the gauge. Anyone can call sweepFees() to credit the escrow and fund the buyback vault. The creator then calls withdrawCreator(token) on the launch’s escrow. Creator balances are tracked per launch token, while protocol balances are tracked per quote asset.
Only the launch’s current feeRecipient(token) may withdraw its creator balance. Use this live value; tokenToCreator(token) is the original creator and can differ after a recipient change or takeover.
After graduation, fees may accrue in either token. Authorized adapter collectors convert the token side to quote and distribute it with non-zero minimum output and an internal price-impact limit. Collection and buyback execution are separate operations; there is no guaranteed payout cadence.
Snapshot boundaries
Section titled “Snapshot boundaries”Curve fee rates and fee splits are copied at launch. Creator tax is fixed at creation. The v4 adapter snapshots its base hook fee at graduation, so integrators should not universally assume the curve and pool rates are identical forever. They match at the currently documented defaults.
