# choose your tier

> the four tiers, what they cost, what they ship with

every launch on waifu.fun picks one of four tiers. the tier is fixed at
`createLaunch()` and cannot be changed. tier math lives in the contract
(`LaunchFactory.tierBudget`, delegating to the `TierMath` library) as a pure
function, not a config table.

## the tiers

| tier (display) | contract enum | presale cap | curve fill (`quoteAmt`) | PCS follow-up buy (`v2BuyBnb`) | vesting |
| -------------- | ------------- | ----------- | ----------------------- | ------------------------------ | ------- |
| SMOL           | TIER\_80      | 16 BNB      | 16 BNB                  | 0 BNB                          | off     |
| BASED          | TIER\_90      | 32 BNB      | calibrated (\~17 BNB)   | cap minus quoteAmt             | on      |
| WAGMI          | TIER\_95      | 64 BNB      | calibrated (\~17 BNB)   | cap minus quoteAmt             | on      |
| GIGACHAD       | TIER\_98      | 160 BNB     | calibrated (\~17 BNB)   | cap minus quoteAmt             | on      |

### what each column means

* **presale cap** is the maximum BNB the vault will accept before deposits get
  rejected. once the cap is hit, the window can close and the bundle bot can
  execute.
* **curve fill (`quoteAmt`)** is how much BNB the bundle pays to FLAP's
  `newTokenV6`. it is dynamically calibrated against the buy tax rate so the
  effective curve fill (after FLAP's 1% protocol fee and the configured buyTax)
  stays at or above 16 BNB plus a 1% safety margin. with default 3% buy tax
  this works out to \~16.84 BNB. SMOL is the exception, it spends exactly
  16 BNB on the curve and does not graduate.
* **PCS follow-up buy (`v2BuyBnb`)** is BNB the bundle spends on the
  freshly-deployed PCS pair in the same atomic transaction. it equals
  `presaleCap minus quoteAmt` so the full cap is spent and no BNB strands
  in the vault. zero for SMOL.
* **vesting** controls how claimers receive their tokens. see
  [vesting explained](/presalers/vesting-explained).

## SMOL: curve only

SMOL (TIER\_80) mints the token and fills the bonding curve. it does not graduate to
PCS v2. the token sits at FLAP's `Tradable` status until organic buyers push
it past the four-fifths threshold (which would auto-graduate it). presalers
get a flat 200M tokens (20% of supply) split pro-rata, same as every other tier.

choose this when:

* you want a lower-stakes launch
* you do not want to commit BNB to seeding v2 liquidity
* you trust organic demand to graduate the token

caveats:

* no PCS pair at launch, so no immediate price discovery on a public AMM
* vesting is off, all tokens unlock at claim
* the token may sit on the curve indefinitely if it never graduates

## BASED: standard

BASED (TIER\_90) is the typical mid-size launch. the bundle fills the curve, graduates
to PCS v2, and follow-up-buys 12 BNB worth of tokens for presalers. vesting
is on (50% at TGE, 50% linear over 24 hours).

choose this when:

* you have a community that can fill 32 BNB
* you want a PCS pair from day one
* you want vesting to dampen early dump pressure

## WAGMI: bigger raise, more buy pressure

WAGMI (TIER\_95) doubles the cap and quadruples the follow-up buy. same graduation
mechanics, same vesting, more buying pressure into the freshly-deployed pair.

choose this when:

* 64 BNB is in your community's reach
* you want a stronger price action moment at launch

## GIGACHAD: max tier

GIGACHAD (TIER\_98) is the big one. 160 BNB cap, 140 BNB into the PCS pair in the same
transaction. this produces the largest immediate buy pressure available on
the platform.

choose this when:

* you have a serious community and serious demand
* you can stomach an under-subscribed refund if the cap does not fill

## how to pick

set the tier where you are at least 80% confident the cap will fill before
the close window. an under-subscribed launch is not a disaster (presalers
get a bonus on refund), but it is a non-event for your token. better to ship
a BASED that fills than aim at GIGACHAD and refund.

## tier math is in the contract

```solidity theme={null}
// from TierMath.sol (called by LaunchFactory.tierBudget)
function tierBudget(uint8 tier, uint16 buyTaxBps)
    internal
    pure
    returns (uint256 presaleCapBnb, uint256 quoteAmt, uint256 v2BuyBnb, bool vestingEnabled)
{
    if (tier == 0) return (16 ether, 16 ether, 0, false); // TIER_80 (SMOL)
    if (tier == 1) presaleCapBnb = 32 ether;              // TIER_90 (BASED)
    else if (tier == 2) presaleCapBnb = 64 ether;         // TIER_95 (WAGMI)
    else if (tier == 3) presaleCapBnb = 160 ether;        // TIER_98 (GIGACHAD)
    vestingEnabled = true;
    quoteAmt = calibratedQuoteAmt(buyTaxBps);             // ~17 BNB at 3% buyTax
    v2BuyBnb = presaleCapBnb - quoteAmt;
}
```

there is no admin function to change these. if waifu.fun wants new tiers we
deploy a new factory.

## treasury LP ladder

every graduating tier also configures a four-step single-sided PCS V3 LP
ladder via `TreasuryLP5`. the 100M tokens (10% of supply) sent to the
treasury get progressively deployed as four overlapping infinity-range V3
positions as the token's TWAP market cap rises through tier targets:

| launch tier | tier 0 entry | tier 1 entry | tier 2 entry | tier 3 entry |
| ----------- | ------------ | ------------ | ------------ | ------------ |
| SMOL        | \$250k       | \$1M         | \$5M         | \$25M        |
| BASED       | \$1M         | \$5M         | \$10M        | \$25M        |
| WAGMI       | \$5M         | \$10M        | \$25M        | \$100M       |
| GIGACHAD    | \$10M        | \$25M        | \$100M       | \$1B         |

those MC values are USD targets; the contract uses a Chainlink BNB/USD feed
plus a TWAP from the FLAP V2 pair to gate tier deployment. see
[after launch](/creators/after-launch) for what happens to the BNB collected
by those LPs.
