Fling a coin. Curve → locked Uniswap v4. Ship the same flow via API.
Fling is a non-custodial memecoin launchpad on Robinhood Chain. Tokens launch on a bonding curve and graduate into a permanently locked Uniswap v4 pool. The protocol keeps the locked liquidity — the ongoing asset is the fee stream, not withdrawable LP — and earns a fee on every swap for the life of the token. Everything the site does is also an API, SDK, or MCP call.
Non-custodial. Permissionless graduation at the exact final curve price. Portable to chains with canonical Uniswap v4 — day one is Robinhood Chain.
Locked LP forever
At graduation, liquidity moves into a Uniswap v4 pool and stays locked. There is no remove-liquidity path on the locker. Traders are not asked to trust a withdrawable LP key.
Fees that pay creators and referrers
1% on every swap (curve and pool). Split: Creator 60% / Protocol 30% / Trade referrer 7% / Create referrer 3%. Launch fee: 0.0005 ETH. LP remint is Phase 2 only — not at launch.
API, SDK, MCP first
Indexers, REST, WebSockets, TypeScript and Python SDKs, MCP, webhooks, referrer bps, DexScreener adapter, example bots. Builders and agents use the same flows as the UI.
- Creators: Locked-LP graduation + 60% of the 1% swap fee for the life of the token.
- Traders: No withdrawable LP rug path after graduation; anti-snipe is buys-only and auto-expires.
- Builders / bots / agents: API-first with SDKs, MCP, webhooks, and referrer attribution.

King of the Hill
Highest market cap still on the curveFling a coin
One transaction, 0.0005 ETH launch fee. Your token trades on a bonding curve until the raise target is hit, then liquidity seeds a Uniswap v4 pool with no withdraw path — fee stream is the asset. Creators earn 60% of every 1% trade fee.
