Launch a token. Free. Open source. On Base or Robinhood Chain.

---

One transaction deploys a fixed-supply ERC-20, opens a Uniswap v4 pool at the market cap you pick and locks 100% of the supply as liquidity in an ownerless locker — forever. Nobody can pull it: not the creator, not us. There is no platform fee: the factory and the locker have no fee address at all. Creators choose a 0 / 1 / 3 % trading fee that is pushed in full to beneficiaries they name, or burned.

What you get

• Free by construction. No fee parameter exists in the contracts, so there is nothing to raise later.
• Rug-proof liquidity. The position NFT lives in a locker with no owner, no pause, no upgrade path and no transfer function. Proven with an adversarial fork suite against the live deployment.
• Two chains, one set of addresses. Base and Robinhood Chain, same contracts, same rules.
• Any quote asset. ETH, USDG, GITLAWB (Gitlawb's token, on Base and bridged 1:1 to Robinhood Chain; priced from its Base Uniswap v4 WETH pool; fees paid or burned in GITLAWB), or a tokenized stock: Coinbase's B20 stocks on Base (NVDAc, AAPLc, TSLAc, …, priced from Chainlink on-chain feeds) and Robinhood Stock Tokens on Robinhood Chain.
• Trade in-page. Buys and sells go straight to the Uniswap v4 pool through the Universal Router; the site never touches funds.
• Live everything. One poller feeds the list, the trending strip, the tape, toasts and totals.
• Holders & trust panel. Every transfer of every launched token is indexed: holder count, top-10 share, creator holdings and sells, launch-window snipers, locked-pool share. Facts, no score.
• Creator dashboard. Fees earned, collect in one click, signed metadata edits, per-token share cards.
• Posts. Wallet-signed comments on token pages and a human feed, with reports and creator mute.
• Agents welcome. Plain JSON APIs, llms.txt, and a launch flow that needs nothing but a wallet.

Deployments

chain	LaunchFactory	LaunchLocker
Base (8453)	0x8155…de72	0xcd16…842a
Robinhood Chain (4663)	0x8155…de72	0xcd16…842a

Full addresses: factory 0x815542E8b392389A1389E22E588E4B62A67Ade72, locker 0xcd1680D26922fcd9CabFbb8a56bA40C333fD842a — identical on both chains (same deployer, first transaction each). Source verified on Basescan, Blockscout (Base and Robinhood Chain) and Sourcify (exact match). Every launched token is verified too. No owner, no admin, no upgrade path.

How it works

launch(params)                       # one call, gas is the only cost
 ├─ LaunchToken   fixed supply, ERC-20 + permit, no mint / pause / blacklist / tax
 ├─ PoolManager   Uniswap v4 pool, single-sided from your start tick to max
 └─ LaunchLocker  holds the position NFT forever; collect() pushes fees to beneficiaries or burns them

Trading fees (if any) are ordinary Uniswap v4 LP fees. collect() is permissionless: anyone can trigger a payout, the recipients are fixed at launch, and a recipient that cannot receive is credited to claim later. Details, invariants and the deploy steps: contracts/docs/LAUNCHPAD.md.

Repository

contracts/	LaunchFactory, LaunchLocker, LaunchToken (Foundry). 47 tests: unit, live-fork on both chains, an adversarial "try to rug it" suite, and a tokenized-stock quote suite. Slither clean.
app/	The site: Next.js 16, React 19, wagmi 3 / viem 2, Postgres indexer for launches, swaps, fees, transfers and holders. 80+ unit tests plus a smoke suite that runs after every deploy.
brand/	Logo tile, OG image and social assets.

Contracts

cd contracts && git submodule update --init --recursive
forge test --match-path test/LaunchFactory.t.sol                       # unit
FORK_TESTS=true forge test --match-contract LaunchLockerRugFork         # rug attempts vs live Base
FORK_TESTS=true forge test --match-contract LaunchStockQuote            # AAPL-quoted launch on Robinhood Chain

App

cd app && npm install
cp .env.example .env.local        # RPCs, factory / locker addresses, DATABASE_URL (a local Postgres is enough)
npm run migrate                   # applies db/schema.sql; reads DATABASE_URL from .env.local
npm run dev                       # http://localhost:3000
npm test                          # unit tests (tsx + node --test)

app/README.md covers local development against anvil forks of both chains; app/LAUNCH.md is the production runbook (deploy, backups, restore). Deploying your own instance: change the app name in app/fly.toml, put production values in app/.env.production, run scripts/fly-secrets.sh, then fly deploy with the four NEXT_PUBLIC_LAUNCH_* build args (see the top of app/fly.toml).

Contributing and security

See CONTRIBUTING.md. Security issues: SECURITY.md — please report privately. CI runs lint, typecheck, unit tests and a production build for the app, and build + unit tests for the contracts, on every pull request.

Security

• No platform fee, no owner, no admin keys, no upgradeability — verified in the source and in the deployed bytecode.
• Liquidity cannot be withdrawn by anyone; see contracts/test/LaunchLocker.rug.fork.t.sol for what was tried.
• Wallet-signed, single-use-nonce authorization for every off-chain write (posts, edits); images are re-encoded server-side; the share-card renderer never fetches user-supplied URLs.
• Tokenized stocks are securities issued by third parties under Regulation S and are not offered to US persons; the site only recognizes them from the issuers' own registries, never from on-chain names.
