V1 vs V2 - InkySwap

V2 is the current launch system. V1 is deprecated. This page exists to help V1 token holders and integrators understand what changed.

Quick comparison

Topic	V1	V2
Launch contract	`TokenFactory` (single contract)	`InkyPumpHook` (UUPS proxy) with swappable modules
Launch contract address	`0x1D74317d760f2c72A94386f50E8D10f2C902b899`	`0x4cC8F6d5B7cE150CCC0A9B7664532B1283b96AC4`
Curve type	Exponential, `price = a * e^(b * x)`	Linear with configurable gain multiplier (1x to 21x)
Target raise	3 ETH (hardcoded)	Configurable per launch, 1 to 5 ETH
Creation fee	0.001 ETH	None
Base trade fee	5 percent	2 percent (1 percent protocol + 1 percent variable)
Anti-snipe	Fee decay 30 percent to 5 percent over 25 seconds	Captcha gate for 0 to 60 seconds (no fee penalty)
Creator earnings	Built into the 5 percent fee	Configurable share of the 1 percent variable fee
Finalization	Add to Uniswap V2 pair, burn LP	Bond to a Uniswap V4 pool with a 0.1 percent swap fee
Architecture	Monolithic	Modular: separate Hook, TradingModule, ViewModule, SaleSplitCalculator
Upgradeability	UUPS proxy on one contract	UUPS proxy with separately upgradeable modules
Referrals on chain	Event field on every trade	Separate `Referral` event emitted only when referral code is present

Fee math compared

V1 (after the 25 second anti-snipe window):

fee = ethIn * 0.05
netForCurve = ethIn - fee

V2 (constant for the full token lifetime, regardless of when you trade):

protocolFee = ethIn * 0.01
variableFee = ethIn * 0.01
netForCurve = ethIn - protocolFee - variableFee   // 98 percent
creatorShare = variableFee * (creatorFeeSplitBps / 10000)
buybackShare = variableFee - creatorShare

What stayed the same

Total supply is still 1,000,000,000 tokens
Tokens still bond from an initial sale pool to an automated market maker
The tokens_v2 table in the API still returns the same shape for V2 tokens that the tokens table did for V1, with extra V2 fields added
The leaderboard still counts trade volume across both versions, with separate formulas
The Emperor of the INK auction still works for any token, V1 or V2

What is new in V2

Per launch target raise (1 to 5 ETH)
Per launch curve steepness (1x to 21x gain multiplier)
Configurable creator vs buyback fee split, updatable after launch
Optional anti-snipe window with captcha gate
Scheduled launches (set a start time in the future)
Optional creator prebuy at launch
On chain referral attribution via a dedicated event

Should you migrate

There is no migration path. V1 tokens stay on V1 contracts and continue to trade. V2 is for new launches.
