# How to Enroll a Challenge?

Buying a Challenge takes a couple of minutes: choose an account size and pay in USDT or USDC. Here's the full flow.

***

## Step 1. Open New Challenge

In the left-hand menu, click **New Challenge**. You'll see all the available plans side by side.

## Step 2. Choose a plan and click Buy

Compare the account sizes and fees, then click **Buy** on the plan you want.

## Step 3. Choose your options and apply a promo code

This is where you pick your payment method, turn on any optional add-ons, and enter a promo code — the **Total** updates automatically as you change them. Select **Cryptocurrency** and choose **USDT or USDC**.

You can enable two optional add-ons here:

* **+10% Profit Split** — raises your profit share by 10% at the Trader stage.
* **Daily Loss Protection** — a one-time safety net for your [daily loss limit](/hashhedge-user-guide/en/daily-loss-calculation.md). Normally, reaching the daily loss limit ends the Challenge. With it enabled, the first time you hit the limit the system instead closes all open positions and cancels your orders, applies the protection, resets your daily loss limit, and lets you keep going. It can only be added at purchase and works **once**.

To use a promo code, type it into the **promo code** field and click **Apply**. A promo code must be applied **before** you pay — it can't be added to an order you've already paid for. If it doesn't work, check the spelling and that it hasn't expired. Then continue to payment.

## Step 4. Choose your currency and network

Select the currency (USDT or USDC) and the network your wallet uses — ERC-20, TRC-20, BEP-20, Arbitrum, Optimism, or Solana — and click **Confirm**. Always send funds on the **same network** you select — sending on a different network can result in lost funds.

## Step 5. Send the exact amount

You'll see the payment amount, a deposit address, and a QR code. Send the **exact** amount of USDT or USDC to that address on the network you chose — scan the QR code or copy the address.

{% hint style="info" %}
You have **30 minutes** to complete the transfer. The page checks for your payment automatically and updates once it's received. USDT and USDC are stablecoins pegged to the US dollar (1 USDT ≈ 1 USDC ≈ 1 USD), so the price stays predictable.
{% endhint %}

## After payment

Your order appears in Orders and their statuses, and once the payment is confirmed, a new account shows up in Your accounts and stages. If a payment window expires, just start the order again from **Orders**. You're ready to start trading the Challenge.
