How it works
Penguin Pad has two permissionless tracks on Robinhood Chain: fair-launch bonding curves and community-funded presales. No KYC. Listings are not endorsements — read the Terms.
01
Connect a wallet
Penguin Pad runs on Robinhood Chain. Anyone with a wallet can launch, buy, sell, or contribute. No KYC and no application queue.
02
Buy or contribute
On a live curve, buy and sell until it graduates at 4.2 ETH. On a presale, contribute only during the start/end window, within the creator min/max and remaining hard-cap room. Withdraw stays open until close, or after a creator cancel. Opening a raise costs 0.1 ETH. Creators pick a start (at least 20 minutes from now) and end date and can cancel before start, or only with more than 24 hours left.
03
Watch progress
Price, raised ETH, and tokens left update as activity comes in. At 4.2 ETH net raised, the curve graduates into LP. Hitting the hard cap does not auto-launch. Click Finalize once sold out, or after the window if the soft cap was met, then claim tokens or refund ETH.
Launchpad
Tokens launch on a bonding curve. Launch fee 0.00025 ETH. Graduates at 4.2 ETH into LP. 1% trade fee, 75/25 creator/platform.
Browse launches →Presale
Opening a raise costs 0.1 ETH. Creators set token name, ticker, supply, ETH caps, and per-wallet min/max. Tokens per ETH and listing rate are derived from supply ÷ hard cap. Live now opens in 20 minutes (factory floor); Schedule a later start if you want. Cancel before start, or only with more than 24 hours left; contributors can still withdraw. Penguin Pad takes 3% of ETH raised. Remaining ETH splits 70–100% LP / 0–30% creator. Hitting the hard cap does not auto-launch. Click Finalize once sold out, or after the window if the soft cap was met, then claim tokens or refund.
Browse raises →Creator Rewards
Creator rewards on Penguin Pad are ongoing trading fees, not a token allocation. Both quick launches and presales list on a Uniswap v4 pool that uses PenguinHook. The pool\u2019s own swap fee is set to 0. The hook takes 1% of the ETH/WETH quote leg on each swap and splits it 75% to the creator and 25% to the platform fee wallet. The creator\u2019s cut is pushed to the creator wallet on that swap.
How the Uniswap v4 creator fee works
After a token graduates or a presale is finalized, trading moves to a Uniswap v4 pool on Robinhood Chain. The opening liquidity position is sent to the dead address (0x000…dEaD) and cannot be withdrawn. Fees are not earned by holding that LP NFT. PenguinHook is attached to the pool. On every swap it takes 1% (TRADE_FEE_BPS = 100) of the ETH or WETH side of the trade — buys and sells — and splits that fee: 75% to the creator wallet and 25% to the live platform fee wallet (penguinProtocol). Both shares are paid in the same transaction as the swap. The creator does not claim after each trade. If the creator wallet rejects the ETH or WETH transfer, that share accrues on the hook and the creator can pull it later by calling claimCreatorFees(token) from the creator address. The platform share is always paid out on the swap. The fee rate and the 75/25 split are fixed in the contracts. They are the same on the bonding curve and on the pool.
On the bonding curve (before graduation)
While a quick launch is still on the curve, the same 1% trade fee accrues (75% creator, 25% platform) and is paid in the graduation transaction when net ETH raised reaches 4.2 ETH. The first five seconds of buys also pay a decaying snipe tax that goes entirely to the fee wallet, not the creator. After graduation, curve trades revert and later fees come only from PenguinHook on the v4 pool.
Presale raise vs. ongoing creator fee
These are separate. On finalize, Penguin Pad takes 3% of ETH raised. Of what remains, the creator can take 0–30% (creatorPct). That ETH is paid once, at finalize. The creator receives no tokens. The rest of the ETH seeds locked LP. Unsold hard-cap tokens are burned. After the pool is live, the same 1% swap fee applies, split 75/25 and sent to the creator wallet automatically on each trade.
FAQ
What is a bonding curve launch?
Launchpad curves are a constant-product market with a phantom quote reserve, so the first buy is not free. Anyone can buy or sell until the curve graduates.
When does a curve graduate?
When net quote into the curve reaches 4.2 ETH. Curve buy/sell stop, remaining curve tokens plus 200M reserved supply seed LP. Create, buy, sell, and claim settle on Robinhood Chain.
How is a presale different?
Opening a presale costs 0.1 ETH. Creators set token name, ticker, supply, ETH soft/hard caps (hard cap ≤ 4× soft cap), and per-wallet min/max. Tokens per ETH and listing rate are derived from supply ÷ hard cap. Choose Live now (opens in 20 minutes, the factory floor) or Schedule a later start and end. Creators can cancel before start, or only with more than 24 hours left; contributors can still withdraw pledged ETH. Effective max is the smaller of that max and remaining room to the hard cap. Contribute is only open during the start/end window. Withdraw stays open until close, or after a creator cancel. Remaining room below minContribution can only fill the hard cap as an exact leftover. Penguin Pad takes 3% of ETH raised on successful raises. Remaining ETH splits 70–100% to LP and 0–30% to the creator. Hitting the hard cap does not auto-launch. Click Finalize once sold out, or after the window if the soft cap was met, then claim tokens at the sale rate; miss it and every wallet can refund 100%.
What fees apply on the curve?
Launch costs 0.00025 ETH from the connected wallet and never enters reserves. Buyers pay a 1% quote-leg trade fee, split 75% creator / 25% platform. That 75% creator share is sent straight to the creator wallet automatically as trades happen — there is no separate claim step. Buys in the first 5 seconds also pay a decaying anti-snipe tax. After graduation, remaining curve tokens seed LP.
