# FAQ

> Frequently asked questions about hoodstar.fun.

## General

<AccordionGroup>
  <Accordion title="What is hoodstar.fun?">
    A meme coin launchpad on **Robinhood Chain** (an Arbitrum Orbit L2 that uses ETH for gas). Anyone can launch a token for free; every token trades on the same fair bonding curve; and successful tokens graduate automatically into a Uniswap v3 pool with permanently locked liquidity.
  </Accordion>

  <Accordion title="What chain is it on, and what do I pay gas in?">
    Robinhood Chain, chain ID **4663**. Gas is paid in **ETH**. It's an EVM chain, so standard Ethereum wallets like MetaMask work — see [Connect a Wallet](/guides/connect-wallet).
  </Accordion>

  <Accordion title="Is hoodstar.fun custodial?">
    No. You trade directly from your own wallet against on-chain smart contracts. The platform never holds your funds, and the contracts have no pause, mint, blacklist, or withdrawal backdoors. See [Security](/protocol/security).
  </Accordion>

  <Accordion title="How much does it cost to launch a token?">
    There is **no creation fee** — you only pay network gas. You can optionally attach ETH to your launch to make the first buy on your own curve.
  </Accordion>
</AccordionGroup>

## Trading

<AccordionGroup>
  <Accordion title="What fees do I pay when trading?">
    A **1% fee** on every bonding-curve buy and sell, taken in ETH: 0.7% to the protocol and 0.3% to the token's creator. After a token graduates, trades happen on Uniswap v3 in a 1% fee-tier pool instead. Details in [Fees](/protocol/fees).
  </Accordion>

  <Accordion title="How does the price move?">
    Deterministically. The bonding curve is a constant-product formula over virtual reserves — buys raise the price, sells lower it, and the exact quote is computable on-chain before you trade. See [Bonding Curve](/protocol/bonding-curve).
  </Accordion>

  <Accordion title="What is graduation?">
    When all 793.1 million curve tokens are sold, the curve closes forever and the raised ETH plus 206.9 million reserved tokens seed a Uniswap v3 pool at the final curve price. The LP is locked permanently. See [Graduation](/protocol/graduation).
  </Accordion>

  <Accordion title="Can the developer rug the liquidity?">
    Not through the contracts. Creators never receive free supply, the curve's ETH is held by the protocol until graduation, and graduated liquidity is locked in an ownerless vault with no withdrawal function. A creator *can* still buy early (visibly, on-chain) and sell later — always check the creator's activity before aping.
  </Accordion>
</AccordionGroup>

## Creators

<AccordionGroup>
  <Accordion title="How do creators earn?">
    Two streams, both claimable on-chain at any time: **0.3% of every bonding-curve trade** while the token is on the curve, and **50% of all Uniswap v3 swap fees** after graduation — forever. See [Creator Rewards](/guides/creator-rewards).
  </Accordion>

  <Accordion title="Do creators get free tokens?">
    No. The creator's only way to own their token is to buy it on the curve at the public price — including the optional "dev buy" at launch, which executes at the same starting price available to everyone.
  </Accordion>

  <Accordion title="Can I change my token after launch?">
    No. Name, ticker, supply, metadata URI, and curve parameters are immutable once launched.
  </Accordion>
</AccordionGroup>

## Platform token

<AccordionGroup>
  <Accordion title="Does hoodstar.fun have its own token?">
    Yes — \*\*$STAR**, which will launch on our own bonding curve with a 100% fair launch: no presale, no team allocation. It has not launched yet; the contract address will be announced on [the $STAR page]\(/introduction/star-token) and our official channels. Anything earlier is fake.

    Join our [Discord](https://discord.gg/q8VwC8ZGp). Remember: the team never DMs first and never asks for your seed phrase.
  </Accordion>

  <Accordion title="Is there an API or SDK?">
    Yes — everything is on-chain and open. Use the [TypeScript SDK](/developers/sdk) or integrate the [contracts](/developers/contracts) directly.
