# Quickstart — buy a coin in 90 seconds

You need three things and nothing else:

1. A **web3 wallet** (MetaMask, Rabby, Trust, Rainbow — anything that speaks WalletConnect).
2. Some **USDT0** on the Stable chain (see [Getting USDT0](/for-users/get-usdt0.md)).
3. This page.

## 1. Open the app

Go to [**unstable.run**](https://unstable.run).

## 2. Connect

Top right → **Connect**. Pick your wallet from the picker.

* Desktop wallets show up in the "Popular" list automatically.
* Mobile wallets scan the WalletConnect QR code.

The wallet may ask you to add the Stable chain — approve. Chain ID `988`, gas token `USDT0`.

{% hint style="info" %}
If your wallet doesn't autoswitch to Stable after connecting, click the network chip in the header — it'll prompt.
{% endhint %}

## 3. Pick a coin from the board

The homepage lists every launched token, sorted by market cap. The one on top is **King of the Pool** — the biggest live market on Unstable right now.

Click any card to open its trade page.

## 4. Buy

On the right of the token page:

1. Panel defaults to **Buy**. Type any USDT amount — or click one of the quick buttons ($10 / $50 / $100 / $500), or **MAX** to spend your full USDT balance minus a small gas buffer.
2. The "You receive" row shows how many tokens the swap will hand back at current price + impact.
3. Click **Buy** → your wallet pops open twice:
   * First tx: approve the SwapRouter02 to spend your USDT0.
   * Second tx: the actual swap.

Both confirm in under a second. Your tokens land in the connected wallet immediately.

## 5. Watch it (or dump it)

The chart on the left updates within a few seconds of the swap landing. Recent trades on the right show your buy row, tagged BUY green.

To **sell**, flip the tab at the top of the trade panel to **Sell**. Quick-percent buttons appear (25 / 50 / 75 / 100%). Click 100% for a full close, or type an amount. Same two-tx flow.

## What's next?

* [Reading the chart](/for-users/reading-the-chart.md) — how to make sense of what you're looking at
* [Launch your own coin](/launching-a-coin/overview.md) — the $2 flow
* [Fees & creator rewards](/under-the-hood/fees-and-rewards.md) — how every 1% swap fee splits 80/20

## 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://docs.unstable.run/overview/quickstart.md?ask=<question>&goal=<endgoal>
```

`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.
