noice is a permissionless smart contract system built on top of doppler's multicurve and uniswap v4. it enables anyone to launch tokens with built-in sniper protection, programmable liquidity, and milestone-based funding — all through a single launchpad contract.

below is how each component works under the hood.

launch mechanism (decay multicurve)

every token launches at a $69K market cap using a decay multicurve.

a multicurve handles price discovery from $69K to $100K, followed by a constant-product position to the max tick. this means liquidity is concentrated in the early price range where it matters most, then spreads evenly as the token grows.

sniper protection is built into the launch: swap fees start at 80% and decay to 2% over the first 30 seconds. this prevents bots from front-running your TGE while allowing normal trading immediately after.

contracts used: DecayMulticurveInitializer and DecayMulticurveInitializerHook.

creator vesting

40% of the token supply is vested linearly over 3 months via sablier. this ensures long-term alignment — your team tokens unlock gradually, not all at once.

vesting applies to all team allocations, so traders know founders are locked in.

contracts & security

all tokens are launched through the launchpad contract, with the fee recipient set to the creator. the smart contracts are pending an upgrade to be fully permissionless.

the codebase is built around a single entry point: bundleWithCreatorVesting — handling token creation, liquidity setup, vesting, and fee routing in one transaction.

public API

four endpoints are live for builders and integrators:

• /api/public/projects — list all projects with pagination, search, and filters

• /api/public/projectByAddress — look up a project by its token contract address

• /api/public/projectByUUID — look up a project by its UUID

• /api/public/stats — aggregate stats across all projects (volume, launches, etc.)
