About Polypad
Polypad is a token launchpad on Robinhood Chain. It lets anyone create an ERC-20 token, sell it on a bonding curve, and move it to a Uniswap V4 pool with permanently locked liquidity once enough ETH has been raised. Creators can also launch NFT collections with a floor vault, a marketplace and token rewards for holders. Every step runs on smart contracts; the site reads launches directly from the chain.
How it works
Launch, trade, stake. In three steps.
- 01
Launch
Create a token in a few minutes: name, ticker, logo and a creator fee from 0% to 5%. The full supply is minted to its own launch contract. No owner, no mint, no tax.
Create a token - 02
Trade
Buy and sell on a bonding curve with a live quote at every step. At the graduation threshold, liquidity moves to Uniswap V4 and is locked permanently.

Stake
Stake tokens in on-chain reward pools created by projects and the community. Track your share, claim rewards and withdraw from the pool page.

How a launch works
- 1
Create
Anyone can launch a token from the Create page: name, ticker, logo, description and links, plus a creator fee between 0% and 5%. The fee is chosen before launch and stays the same after graduation. The full fixed supply is minted once to the token’s own launch contract. The token has no owner, mint, pause, blacklist or transfer tax.
- 2
Commitment window (optional)
The creator can open a commitment window of 24 hours, 3 days or 7 days before trading starts. During the window, users commit ETH and can withdraw it in full at any time. When the window ends, anyone can trigger the launch: the creator’s dev buy executes first, then commitments are filled in batches at curve prices.
- 3
Bonding curve
80% of the supply is sold on a constant-product bonding curve priced in ETH. The price rises as tokens are bought and falls as they are sold, so there is always a quote to buy or sell. The token page charts market cap over time from on-chain trades and shows progress toward graduation.

Graduation to Uniswap V4
When the ETH raised reaches the graduation threshold, the launch graduates automatically in the same transaction. The raised ETH and the reserved 20% of supply are added as full-range liquidity to a Uniswap V4 pool at the final curve price. That liquidity is held by the Polypad hook contract, which has no code path to remove it, so it is locked permanently.
NFT collections
Creators can launch PFP collections with one image and metadata file per NFT, sold in one of two ways.
Commitment-window collections
Fixed mint price. During a 24-hour, 3-day or 7-day window, buyers commit ETH. If more NFTs are committed than the supply, everyone receives the same share and the rest of their ETH is refunded when they claim. Leftover supply can be minted afterwards at the same price.
Bonding-curve collections
The price of each NFT rises by a fixed step for every NFT held and falls when one is sold back. Holders can sell back to the pool at the curve price until every NFT is in circulation. At that point the collection graduates: the creator’s chosen share of the pool (20% to 80%) becomes a floor vault and the rest goes to the creator.
Floor vault
Every collection keeps part of the ETH paid for its NFTs in the collection contract. Any holder can burn an NFT at any time to receive their share. Nobody, including the creator, can withdraw it otherwise.
Marketplace and royalties
Holders can list NFTs at a fixed price and buyers can make offers on a specific NFT or on any NFT in a collection. The creator royalty (0% to 10%, ERC-2981) is paid on every sale through the Polypad marketplace.
Token rewards
A creator can deposit an ERC-20 token amount for each NFT in a collection. Each holder claims the reward for the NFTs they hold, once per NFT, before the deadline the creator set.

FAQ
What fees do I pay?
Each token has a creator fee between 0% and 5%, chosen at launch and fixed for the life of the token. It is shown on the token page before you trade. Every transaction also pays a small network gas fee on Robinhood Chain.
What happens to liquidity?
When a launch reaches its graduation threshold, the raised ETH and the reserved 20% of supply are added as full-range liquidity to a Uniswap V4 pool. That liquidity is held by the Polypad hook contract, which has no code path to remove it, so it is locked permanently.
How does staking work?
Anyone can create a staking pool for a token and fund it with rewards. Rewards are paid per second to stakers in proportion to their share of the pool, so the APR is variable. Always check the token address before staking.
Is Polypad custodial? Is it safe?
Polypad is non-custodial: your funds stay in your wallet or in the on-chain contracts, and every action is a transaction you sign yourself. The launch contracts were audited by Bevour AI Security and their source is verified. Health scores and X-ray scans are automated signals, not audits. New tokens are high risk.
Risks
Tokens launched on Polypad are created by their users, not by Polypad. Prices on a bonding curve can move quickly and most new tokens lose value. The contracts have been audited by Bevour AI Security, but an audit does not remove all risk. Only commit or trade what you can afford to lose.
