MECHANICS / FEES

Fee schedule and caps

Two numbers matter for every fee: what the contract will never allow, and what it is currently set to. The first is a constant in the source. The second is an owner setting, which will be published when the launchpad opens.

Hard caps (constants in the source)

Constant	Value	Where	What it bounds
`MAX_CURVE_FEE_BPS`	1,000 bps = 10%	V2 factory	The base trade fee a launch config may charge on the curve
`MAX_CREATOR_TAX_CEILING_BPS`	1,000 bps = 10%	V2 factory	How high the owner may raise `maxCreatorTaxBps`
`MAX_TOTAL_TRADE_FEE_BPS`	2,000 bps = 20%	V2 factory, curve and hook	Curve fee + creator tax, and hook fee + creator tax. Checked in all three places
`MAX_HOOK_FEE_BPS`	1,000 bps = 10%	V2 hook	The ceiling on the per-swap fee in a graduated pool
`MAX_PROTOCOL_FEE_SHARE_BPS`	5,000 bps = 50%	V2 hook	The protocol's share of that fee. The protocol can never take more than half
`MAX_SNIPE_TAX_START_BPS`	9,900 bps = 99%	V2 factory	The launch-second snipe tax, held below 100% so a taxed buy still nets something
`MAX_SNIPE_TAX_SECONDS`	60 s	V2 factory	The snipe tax decay window
`MAX_SNIPE_TAX_EXEMPTIONS`	32	V2 factory	Addresses a creator may exempt at launch
`CREATOR_FEE_RECIPIENT_TIMELOCK`	3 days	V2 factory	Notice before an owner-proposed creator-recipient override can execute (plus a 3-day execution window)
`GRADUATION_RESCUE_DELAY`	7 days	V2 factory	How long a swept launch must sit before its reserves can be released manually
`MAX_PROTOCOL_FEE_SHARE`	50 (percent)	V1 locker	The protocol's share of collected LP fees

AGI settings (as read from the deployed contracts)

hookFeeBps = 100 — 1% per swap in a graduated pool, taken by the hook. The ceiling is 10 times that, so read this as a setting, not a promise.
curveFeeBps = 100 — 1% on every buy and sell on the curve. It lives in the launch config and each curve freezes it at launch, so a trade pays the same rate before and after graduation.
protocolFeeShareBps = 3000 — 30% of the base fee goes to the protocol wallet, 70% to the creator.
maxCreatorTaxBps = 200 — a creator may add up to 2% on top, paid 100% to the creator. Set after deploy; the contract's initial value is 1000 (10%), which is also its hard ceiling.
snipeTaxStartBps = 9900, snipeTaxSeconds = 5 — the launch-second snipe tax and its window, stored on the V2 factory. The window was set after deploy; the contract's initial value is 15 s. The curve trims the start rate so a buyer always keeps at least 1% after all fees: 98% with no creator tax, 96% at the 2% cap.
launchFee — 0.0005 ETH, paid to the protocol wallet in the launch transaction.

These are the settings intended for the AGI Launchpad, not published live values: the launchpad is not open yet. Every one of them is a starting value the owner may change afterwards, inside the ceilings above (the launch fee has no ceiling). A change only reaches launches created after it: a token keeps the terms it launched with. The values on chain take precedence over this page.

How a V2 trade is split

On the curve, a buy or sell pays the 1% base fee (curveFeeBps) plus the creator tax (creatorTaxBps, 0 to 2%) on its quote leg. A buy inside the snipe window pays the snipe tax as well.
In a graduated pool, the hook takes the same 1% (hookFeeBps) plus the same creator tax from the swap's unspecified currency, in one take from the pool manager's ledger, crediting the two cuts to separate ledgers.
At sweep time the base fee splits 30% to the protocol wallet and 70% to the creator (protocolFeeShareBps).
The creator tax goes 100% to the creator. It never enters the split.
The snipe tax joins the base fee and splits the same way: 30% protocol, 70% creator.
Every payout is credited to AgiV2FeeEscrow and waits there until its recipient claims it: the protocol wallet claims the protocol's 30%, the creator fee recipient claims the 70% plus the tax. The escrow pays the caller's own balance only; nobody can claim another's.

A fee change never reaches a token that already launched

Each curve receives the fee policy as constructor immutables, and each graduated pool is registered with the policy snapshotted at its launch. Retuning the hook governs launches from that moment on. This is also why expectedEconomics exists: it is the creator's protection in the window between reading the terms and their transaction landing.
