LaunchHouse

Contract behavior is the source of truth. If this page and a live factory disagree, treat the contract as current.

Overview

LaunchHouse is a launchpad. Native launches go through LaunchHouse factories (EVM) or the LaunchHouse Solana program and open into locked liquidity. The homepage also indexes external Pons, pump.fun, and stonk.fun markets. Those listings are discovery only — LaunchHouse taxes and protections do not apply.

How launches work

EVM launches mint 1,000,000,000 tokens, seed a one-sided Uniswap V3 position at a $5,000 tick, and lock the NFT. The creator does not deposit ETH. Solana launches use Raydium LaunchLab. Rules written at create — tax, Launch Protection, sell control, exemptions — are immutable.

Fees

Every LaunchHouse EVM token takes 0.50% house tax on pair-touching transfers. After a LaunchHouse buy or sell, that tax is sold into the pair and sent to the LaunchHouse wallet. Creators may add up to 10% extra token tax and split it across creator, house, holders, and auto-LP.

Launch Protection

Every EVM launch opens a 3-second window with a 99% tax that decays to 0. The deployer wallet is exempt, including a developer buy in the launch transaction. Collected tax is sold into the pair and sent to the LaunchHouse wallet — it is not split with the creator or holders. The window and exemptions cannot be changed after launch.

Sell Controls

Off by default. A creator may add a timed per-trade sell cap (0.25%–5% of supply) and an optional 0–60s cooldown. The window lasts at most 1 hour, then expires and cannot be extended. There is no blacklist, trading pause, or post-launch exemption list. Permanent / forever caps are rejected by new factory source and are not offered in the UI. Tokens already deployed with a permanent cap are labeled as a warning, not as a standard LaunchHouse launch. Live factories still accept a permanent duration if called directly until a new factory is deployed — see contracts/MIGRATION-SELL-CONTROL.md.

Exemptions

Launch Protection exemptions are set at create. The factory always inserts the deployer. Extra exemption slots exist on-chain but the UI only exempts the connected deployer. Sell control has no wallet exemptions. No exemptions can be added after launch.

Liquidity locking

EVM LP is a Uniswap V3 NFT held by the locker. The locker has no withdraw. Solana House LP locks on Raydium CPMM at graduation.

Graduation

EVM graduation is pool status once the pool holds 3 ETH — the NFT stays locked. Solana climbs until the curve has raised 25 SOL, then Raydium lists on CPMM with House LP locked.

Base

Uniswap V3 one-sided ETH pools. Tax lives on the token, so the house cut still applies after listing.

Robinhood Chain

Same factory shape against USDG / stock quotes. Launch Protection and optional timed sell control apply.

Arc

Live on testnet against native USDC. Same tax, 3s Launch Protection, optional sell control, locked NFT.

Solana

Token-2022 coins on Raydium LaunchLab. House takes 0.5% in the quote on the curve. There is no 3-second Launch Protection and no sell cap. Harvested Token-2022 fees go to qbjbLafSNGq27fYFiF1RKhb9BREk1zFWWS8H6Drj8co.

pump.fun launches

pump.fun is an optional create path and an indexed market. There is no House tax, Launch Protection, or sell control. Cards show the source as Pons, pump.fun, or stonk.fun.

Claims

Fees are pulled, not pushed. Creator share is one balance per chain and pair asset. Holder dividends and auto-LP sit on each token. The house 0.5% is sent to the LaunchHouse wallet and is not claimed.

Risks

New tokens may have no wallet price feed. Wallet simulations can disagree with LaunchHouse quotes. Indexed markets are not LaunchHouse contracts. Permanent sell caps on legacy tokens can look like honeypots and are labeled as warnings. Never ignore a wallet or security warning.

Contract addresses

House tax wallet 0x1CAd2652b6a3d71f28898B75A244B180B6559187. Factory addresses come from deployment env vars and may differ from repo defaults — check the live venue config before you send a transaction.

Security and audits

Tokens expose owner() = 0, paused() = false, and isBlacklisted() = false. There is no public audit report in this repository. Treat unaudited contracts as high risk. One-click trading keys are generated in your browser and never leave the device — LaunchHouse does not hold your keys or funds. Export a backup if you fund a session; anyone with the file can spend it.
