Token Creation

Launches happen through two entry points on the InkyPump V2 hook at 0x4cC8F6d5B7cE150CCC0A9B7664532B1283b96AC4. Use createLaunch for a plain launch. Use createLaunchWithReferral to record a referral code on chain at creation time.

createLaunch

function createLaunch(InkyPumpTypes.CreateLaunchParams calldata params)
    external payable returns (uint256 launchId);

msg.value is the optional creator prebuy. Send 0 for no prebuy. Send any positive amount to prebuy that much ETH at the curve’s starting price in the same transaction. Returns the new launchId. The launch’s token address is in the LaunchCreated event emitted by the same call.

createLaunchWithReferral

function createLaunchWithReferral(
    InkyPumpTypes.CreateLaunchParams calldata params,
    string calldata referralCode
) external payable returns (uint256 launchId);

Same behaviour as createLaunch, plus a Referral event recording the code:

event Referral(uint256 indexed launchId, address indexed trader, string referralCode);

If referralCode is empty, this still works but does not emit the Referral event. Use the plain createLaunch when you do not have a referral code.

CreateLaunchParams

struct CreateLaunchParams {
    string name;
    string ticker;
    string description;
    string imageUrl;
    string telegram;           // optional
    string twitter;            // optional
    string website;            // optional
    uint16 creatorFeeSplitBps; // 0 to 10_000
    uint32 gainBps;            // 0 to 200_000 (1x to 21x)
    uint96 targetRaise;        // 1 ether to 5 ether
    uint32 antiSnipeDuration;  // 0, 20, 40, or 60 seconds
    uint64 startTime;          // 0 for immediate, future unix timestamp for scheduled
}

Prebuy

There is no prebuyEth field. To prebuy at launch, send the prebuy amount as msg.value on the createLaunch call. The creator’s prebuy executes in the same transaction as the launch, at the curve’s starting price, and bypasses the anti-snipe captcha gate.

Field constraints

Field	Constraint	Reverts if violated
`targetRaise`	Between `MIN_RAISE` (1 ether) and `MAX_RAISE` (5 ether)	`RaiseOutOfRange`
`gainBps`	At most `MAX_GAIN_BPS` (200,000)	`GainTooHigh`
`creatorFeeSplitBps`	At most `BPS_DENOMINATOR` (10,000)	`SplitOutOfRange`
`msg.value`	0 (no prebuy) or any positive amount your wallet can cover	none directly
`startTime`	Either 0 or in the future	`LaunchInPast`

What happens during the call

The hook deploys a new ERC20 token with the supplied metadata
It computes the sale supply and liquidity supply for the curve through SaleSplitCalculator(targetRaise, gainBps)
It records the LaunchConfig in storage at the new launchId
It emits LaunchCreated and LaunchMetadata
If msg.value > 0, it executes the creator prebuy at the curve’s starting price
If called as createLaunchWithReferral with a non empty code, it emits Referral

Events emitted

event LaunchCreated(
    uint256 indexed launchId,
    address indexed creator,
    address token,
    uint96 targetRaise
);

event LaunchMetadata(
    uint256 indexed launchId,
    string name,
    string ticker,
    string description,
    string imageUrl,
    string telegram,
    string twitter,
    string website
);

event SalePortionResolved(
    uint256 indexed launchId,
    uint16 salePortionBps,
    uint256 marginalPrice,
    uint256 poolPrice
);

If msg.value > 0, a Trade event also fires for the prebuy.

Example: minimal launch

import { encodeFunctionData, parseEther } from "viem"

const params = {
  name: "My Token",
  ticker: "MINE",
  description: "Launching on InkyPump V2",
  imageUrl: "https://example.com/logo.png",
  telegram: "",
  twitter: "",
  website: "",
  creatorFeeSplitBps: 7000,     // 70 percent of variable fee to creator
  gainBps: 50_000,              // 6x gain
  targetRaise: parseEther("3"),
  antiSnipeDuration: 40,        // 40 second captcha gate
  startTime: 0n,
}
// To prebuy, send ETH with the transaction (set `value` on the tx call below).

const data = encodeFunctionData({
  abi: INKY_PUMP_HOOK_ABI,
  functionName: "createLaunch",
  args: [params],
})

const hash = await wallet.sendTransaction({
  to: "0x4cC8F6d5B7cE150CCC0A9B7664532B1283b96AC4",
  data,
  value: 0n,
})

Common errors

Revert	Cause
`RaiseOutOfRange`	`targetRaise` is below 1 ether or above 5 ether
`GainTooHigh`	`gainBps` exceeds 200,000
Tx out of funds	Wallet does not have enough ETH for gas plus `msg.value` prebuy
`LaunchInPast`	`startTime` is in the past and not zero
`SplitOutOfRange`	`creatorFeeSplitBps` is above 10,000
