Architecture

V2 splits the launch system into a UUPS proxy plus separate stateless modules. The proxy holds state and routes calls. The modules implement the logic.

InkyPumpHook (proxy, holds state)
  ├── delegates trading logic to LaunchTradingModule
  ├── delegates view / preview logic to LaunchViewModule
  └── state lives in LaunchSharedState

Helpers:
  SaleSplitCalculator (decides sale supply vs liquidity supply per launch)
  LaunchAccounting (computes fee splits)
  LinearBondingCurve (forward and inverse curve math)

Modules are stateless and swappable. An admin can deploy a new LaunchTradingModule and point the proxy at it through configureModules, without redeploying the hook itself.

Why modular

Bug fixes ship as a module redeploy without touching the proxy or its state
Each module can be audited independently
New features (like the referral variants of buy and sell) added by upgrading the trading module

Common integration entry points

What you want to do	What to call
Launch a token	`createLaunch` or `createLaunchWithReferral` on the hook
Buy on the curve	`buy` or `buyWithReferral` on the hook
Sell on the curve	`sell` or `sellWithReferral` on the hook
Preview a buy	`previewBuyLocal(...)` on `LaunchViewModule`, with state from `getLaunchState`
Preview a sell	`previewSellLocal(...)` on `LaunchViewModule`, with state from `getLaunchState`
Read launch state	`getLaunchState(launchId)` on the hook
Update creator fee split	`updateCreatorFeeSplit(launchId, newSplitBps)` on the hook
Withdraw accrued fees	`withdrawFees()` on the hook
Swap a bonded token	Uniswap Universal Router on the V4 pool

Constants

From LaunchSharedState.sol:

uint256 public constant TOTAL_SUPPLY      = 1_000_000_000 ether;
uint256 public constant MIN_RAISE         = 1 ether;
uint256 public constant MAX_RAISE         = 5 ether;
uint32  public constant MAX_GAIN_BPS      = 200_000;     // 21x ceiling
uint256 public constant MIN_BUY_ETH       = 0.00001 ether;
uint128 public constant MIN_SELL_TOKENS   = 1 ether;
uint256 public constant PROTOCOL_FEE_BPS  = 100;         // 1 percent
uint256 public constant VARIABLE_FEE_BPS  = 100;         // 1 percent
uint256 public constant BPS_DENOMINATOR   = 10_000;
uint24  public constant POOL_FEE          = 1_000;       // 0.1 percent on V4 pool

Legacy Contracts

V1 contract addresses.

Always verify contract addresses before calling. The proxy at 0x4cC8F6d5B7cE150CCC0A9B7664532B1283b96AC4 is the only V2 entry point. If you see a different address claiming to be the V2 hook, treat it as untrusted.
