Fees

Each curve or routed trade pays a protocol trading fee. The live rate is factory.protocolFeeBps(). The display default in this app is 2.00% (200 bps). Factory admin may set that rate from 0 to 5%. Creators cannot change it.

Fees fund protocol operations, a safety reserve, creator share, and referrals without putting a token tax in the standard launch path.

• The fee is taken in the quote asset and accrued to the Fee Vault. It is not paid as an inline token tax on the Standard template. Fee and Rewards templates can add a separate token-side tax after Ignition; that tax is set at launch and cannot change.
• Display default vault split of each received fee: Protocol 24%, Safety 16%, Creator 40%, Referrer 20%. Live split is vault.protocolShareBps() / safetyShareBps() / creatorShareBps() / referralShareBps().
• Vault admin may setFeeShares. The four shares must sum to 10,000 bps, each at most 50%, safety at least 10%. A change applies to later accruals only; existing credits stay.
• The terminal folds the safety reserve into Protocol so the three claimable shares sum to 100%.
• Unattributed referral share folds to Protocol.
• Creators and referrers self-claim per raise asset listed on the quote-asset registry.
• Arc network gas is paid in USDC.
• Do not grant the Fee Vault a persistent token allowance. Accrual uses exact ephemeral approvals from protocol contracts.

Admin can change the live trading fee within the factory cap; it applies to all launches. A higher fee changes your fill. Vault admin can change the fee-share split within vault caps (future accruals only) and can pause new accruals (claims stay available). Gas and routing costs sit on top of the trading fee.

Read the fee on the ticket from the live factory value when the app is wired. Treat the percentage in these docs as the display default unless the page says it read the chain.
