# Stablecoin Trading

UnicornX App now supports stablecoin trading (USDT, USDC, USD1). You can use stablecoins for deposits, withdrawals, trading, and copy trading.

## Supported Scope

Currently supports the following chains and stablecoins:

| Chain  | Native Token | Supported Stablecoins |
| ------ | ------------ | --------------------- |
| BSC    | BNB          | USDT, USD1            |
| Solana | SOL          | USDT, USDC            |

{% hint style="info" %}
**Important Notice:**

Stablecoins with the same name will be displayed independently on different chains, for example:

* USDT (BSC)
* USDT (Solana)

These are different assets, please pay attention to distinguish them.
{% endhint %}

***

## Depositing Stablecoins

### Navigation Path

Assets Page → Deposit → Select Chain → Select Token

### Steps

1. Click "Deposit" on the Assets page
2. Select chain (e.g., BSC / Solana)
3. Select token (e.g., USDT, USDC, USD1)
4. The system will display:
   * Deposit address QR code
   * Deposit address text (copyable/shareable)

{% hint style="danger" %}
**Security Warning:**

Do not send assets to the wrong chain, or they will be permanently lost.

For example: Do not deposit Solana USDT to a BSC USDT address.
{% endhint %}

***

## Withdrawing Stablecoins

### Navigation Path

Assets Page → Withdraw → Select Token → Enter Amount

### Withdrawal Instructions

* When withdrawing, the list will show all available tokens: BNB, SOL, USDT (BSC), USDT (Solana), USDC (Solana), USD1 (BSC)
* Select the corresponding chain and token, enter the amount, and submit

***

## Trading & Quick Trade Settings

### Regular Trading

* The trading page will display balances based on the token you selected in "Quick Trade Settings"
* Cost estimation (Est. Cost) is uniformly displayed in USDT

### Quick Trade Settings

#### Navigation Path

Home Page → Quick Trade Settings → Select Chain (e.g., BSC / Solana) → Start Setting

#### Setting Instructions

* You can independently set quick amounts for each token (e.g., 10U, 50U, 100U, 200U)
* Supported tokens: BNB / SOL / USDT / USDC / USD1
* Default initialization values:
  * USDT/USDC/USD1: 10, 50, 100, 200 U
  * Native tokens (BNB, SOL): System preset

{% hint style="success" %}
**Usage Suggestion:**

If you frequently use stablecoin trading, it's recommended to set up common amounts in advance for convenient one-click ordering.
{% endhint %}

***

## Signal Copy Trading

### Copy Trading Settings

* Copy trading uses the token selected in "Quick Trade Settings" by default
* Categorized by chain:
  * Solana chain → Can choose SOL / USDT / USDC
  * BSC chain → Can choose BNB / USDT / USD1

{% hint style="info" %}
**Copy Trading Mechanism:**

Your copy trading token is not affected by the group leader and depends entirely on your own settings.

For example: If the group leader sends a signal with USD1, but you have set USDT, the copy trade will automatically place orders with USDT.
{% endhint %}

***

## Assets Page

### Display Rules

Display method: Single token, multiple chains, fixed order:

1. BNB (native)
2. SOL (native)
3. USDT (BSC), USDT (Solana)
4. USDC (Solana), USD1 (BSC)
5. Other tokens sorted by recent trading time

### Record Display

In trading records & deposit/withdrawal records, it will show quantity + token, such as:

* 100 USDT
* 1.2 SOL

***

## Stablecoin Authorization (EVM Chains)

### Authorization Mechanism

* USDT, USD1, etc. are ERC20 tokens that require authorization (approve) before first trading
* The system will automatically detect authorization status:
  * If not authorized → Pop-up prompt → Click confirm → Wait for block confirmation
  * Trading can continue after authorization is complete

{% hint style="warning" %}
**Important Notes:**

When using USDT or USD1 for the first time, please be patient and wait for authorization on-chain confirmation.
{% endhint %}

***

## Referral Mechanism

### Referral Rules

Referrals will be settled according to the token used by the user for trading:

* If your friend trades with BNB/USDT/USD1 on BSC chain → You get referral rewards in the corresponding token
* If your friend trades with SOL/USDT/USDC on Solana chain → You get referral rewards in the corresponding token

### Viewing Referrals

On the referral page, you can view:

* Total referral amount (≈USD)
* Referral details by token (BNB, SOL, USDT, USDC, USD1)

***

## Frequently Asked Questions

### Q1: Why do I have two USDT records?

**A:** Because USDT on BSC and Solana chains are different assets and will be displayed independently.

### Q2: Why do I need to authorize before trading?

**A:** USDT and USD1 are ERC20 tokens that must be authorized to the contract before use.

### Q3: Will referrals be uniformly converted to USDT?

**A:** No, referrals are settled in the actual token used by your friend for trading.

***

## Security Reminders

{% hint style="danger" %}
**Important Security Matters:**

* Before depositing/withdrawing, make sure to confirm that the chain & token correspond
* Never reveal your private key/mnemonic phrase; officials will never ask for them in any form
* When using ERC20 stablecoins for the first time, please confirm that the authorization transaction is successfully on-chain
