Fees and proceeds
The current curve separates trading fees from the quote reserve. Amounts are recorded in the launch's quote asset. Network transaction costs are separate.
On Base that quote is USDC, and gas is paid in ETH. On Stellar the quote is XLM or USDC, and network fees are paid in XLM.
Creator trading fee
creator_fee_bps is applied on each buy and sell. The creator chooses it at launch, up to 1,000 basis points, or 10%.
- A buy pays the gross curve cost plus the fee.
- A sell receives the gross curve proceeds minus the fee.
- Fees are rounded up to the smallest quote-asset unit.
For example, a 100 USDC gross buy with a 100 bps fee costs 101 USDC before network fees. A 100 USDC gross sell with the same fee returns 99 USDC.
The owner withdraws accrued fees with the vault's fee-claim method. This does not withdraw trading reserves, direct donations, or a graduation payout. Keeping fee withdrawals separate lets trading continue even when the owner's receiving account needs attention.
Graduation accounting
creator_payout_bps describes the share of recorded quote reserves earmarked for the creator at graduation. The factory's platform_fee_bps describes the platform share. The remaining recorded quote reserve is shown as the planned pool quote amount.
The platform fee is capped at 1,000 bps. Creator payout plus platform fee cannot exceed 10,000 bps. The creator cannot override the factory's platform fee for an individual launch.
On Stellar these amounts are exposed through graduation_preview(). The current Stellar contract does not pay them out or create a pool. A preview is not withdrawable proceeds. On Base, follow the live launch for settlement.
Basis points
100 bps = 1% and 10,000 bps = 100%. Allocation percentages and fee percentages are different parameters and should be reviewed separately.
Network fees
Base transactions consume ETH for gas. Stellar transactions consume XLM for network fees, and accounts also need sufficient reserves for entries such as trustlines. Resource costs depend on the transaction and network conditions; use simulation rather than a fixed fee promise.
Auction and presale fee schedules are published on the live Base launch. A Stellar sale must disclose fees and proceeds-release rules before accepting commitments.
