# Purchase with Crypto or Card (Credit/Debit)

Shell Buyer is a web application for purchasing SHELL tokens using a credit/debit card or cryptocurrency. Available at [shellbuy.ackinax.com](https://shellbuy.ackinax.com/).

## How It Works

The purchase consists of three steps:

1. **Connect Wallet** — scan a QR code with your Acki Nacki Wallet to link it
2. **Choose Package** — select a token package and pay with a card or crypto
3. **Confirm & Receive** — SHELL tokens are delivered directly to your wallet

## Prerequisites

* A browser (Chrome, Firefox, Safari, or any modern browser)
* [Acki Nacki Wallet app](https://ackinacki.com/wallet) installed on your phone
* A credit/debit card (Visa, MasterCard) **or** cryptocurrency (USDC, USDT)

{% hint style="warning" %}
**Important:** send the exact amount shown. The payment must be sent before the timer expires. Payments below the minimum amount cannot be processed. Completed payments are non-refundable.
{% endhint %}

Once the payment is detected, the status changes to **Payment Processing**:

{% endtab %}
{% endtabs %}
{% endstep %}

{% step %}

#### Track Your Order

After payment, the **Order Status** page shows a progress bar with five stages:

1. **PENDING** — order created
2. **PAYMENT CREATED** — payment initiated
3. **PAYMENT CONFIRMED** — payment confirmed by the provider
4. **MINTING** — SHELL tokens are being minted on the Acki Nacki chain
5. **DELIVERED** — tokens have been sent to your wallet

The **Order Details** section displays: Order ID, Status, Amount, SHELL Tokens, Payment Method, Created timestamp, Delivery Transaction link, and Delivered At timestamp.

<figure><img src="/files/RhUaX4VMx4gmlDavUqph" alt="" width="375"><figcaption></figcaption></figure>
{% endstep %}

{% step %}

#### Order Delivered

When all stages are complete, the status shows **DELIVERED** with confirmation badges: **Minter** ✓ and **On-Chain** ✓. An **On-Chain Verified** timestamp confirms that the tokens have been verified on the Acki Nacki blockchain.
