# Introducing Roost
Launch and trade tokens on Robinhood Chain.
### Introduction
Roost's mission is to give every builder on Robinhood Chain a direct path from idea to live market. Roost is a place to launch and trade tokens:
> ***A creator deploys a fixed-supply token, opens its market, and starts trading from a wallet in one flow.***
Every launch goes straight to a Uniswap V4 pool. There is no bonding curve, no graduation threshold, and no later migration. Trading starts the moment the launch transaction confirms.
**Roost is built on Uniswap V4 hooks.** Each market carries its own fee logic: a customizable trading tax that the token dev sets between 1% and 10%, captured entirely by the market's hook.
There is no separate LP fee. Creators choose how that tax works through two launch modes, creator mode and vault mode, described below.
Creators add the token details, choose the payment token, and sign the launch. Buyers and sellers approve their own trades. Roost never holds user funds.
Robinhood Stock Tokens make Roost markets different. Instead of pairing only with ETH, a creator can pair a new token with a supported onchain Stock Token, so a launch can trade directly against tokenized exposure to companies like SpaceX or NVIDIA.

### Key facts
The same basic terms apply to every launch, and they stay visible on the token page.
**Straight to Uniswap V4.** Every launch creates a live pool at launch time. No bonding curve, no migration.
**Fixed supply.** Every Roost token launches with a fixed supply.
**ETH or a Stock Token.** Each market uses one payment token: ETH or one supported Robinhood Stock Token.
**Customizable tax, 1% to 10%.** The token dev sets the trading tax. The market's V4 hook collects all of it; there is no separate LP fee.
**Two fee modes.** Creator mode routes the tax to creator-designated wallets. Vault mode routes every fee into the token's vault for buyback and burn or holder airdrops.
**Self-custody throughout.** Users approve every transaction in their own wallet. Roost never holds funds.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://roostlaunch.gitbook.io/roost-docs/welcome-to-roost/introducing-roost.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
