# How to Sell SHELL
Selling SHELL is done through the Acki Nacki Wallet. You choose a lot denomination, confirm — and your SHELL is locked until sold. When a buyer arrives, the lot is sold automatically on a first-come-first-served (FIFO) basis.
{% hint style="warning" %}
**Important:** once a sell order is confirmed, cancellation is not possible.\
Your SHELL will remain locked until sold.
{% endhint %}
## Prerequisites
* [Acki Nacki Wallet app](https://ackinacki.com/wallet) installed
* SHELL in your balance (minimum 100 SHELL for the smallest lot)
## Step-by-Step Guide
{% stepper %}
{% step %}
### Open Exchange
On the wallet's main screen, tap the **Exchange** button.
{% endstep %}
{% step %}
### Select Buy & Sell SHELL
On the Exchange screen you'll see two options. Tap **Buy & Sell SHELL** (Trade SHELL with USDC).
{% endstep %}
{% step %}
### Switch to Sell
On the "Buy & Sell SHELL for USDC" screen, two buttons are displayed at the bottom: **Sell** and **Buy**. Tap **Sell**.
{% endstep %}
{% step %}
### Choose a Lot Denomination
The **Sell SHELL** panel opens with the prompt "Choose how much USDC you want to receive." Four denominations are available:
| You Sell | You Receive |
| :-----------: | :---------: |
| 100 SHELL | 1 USDC |
| 1,000 SHELL | 10 USDC |
| 10,000 SHELL | 100 USDC |
| 100,000 SHELL | 1,000 USDC |
Denominations that exceed your SHELL balance are unavailable. Your current SHELL balance is displayed at the bottom of the screen.
Tap the desired denomination. In this example, the **1,000 SHELL → 10 USDC** lot is selected.
{% endstep %}
{% step %}
### Confirm the Sale
A confirmation screen appears:
Tap **Confirm** to proceed or **Cancel** to go back.
{% endstep %}
{% step %}
### Order Placed
After confirmation, you'll see a screen with the order details:
* **Sell:** 1,000 SHELL
* **Receive:** 10 USDC
* **Position in queue:** #1
The queue number shows how many lots of this denomination are ahead of you. The lower the number, the sooner your lot will be sold.
Tap **Close** to return.
{% endstep %}
{% step %}
### Check the Result
After placing the order:
* Your SHELL balance decreased (was 5,000, now 4,000 — 1,000 SHELL is locked)
* The SHELL token screen now shows a **My Orders** section with your lot and its queue position
Your SHELL balance on the main wallet screen updates automatically.
{% endstep %}
{% endstepper %}
## How to Sell a Larger Amount
Each transaction creates one lot of one denomination. To sell more SHELL, simply repeat the process multiple times, choosing the denominations you need.
**Example:** you want to sell 15,400 SHELL (= 154 USDC). Create lots:
1. 1 × 100,000 SHELL (= 1,000 USDC) — if you have enough balance, or skip
2. 1 × 10,000 SHELL (= 100 USDC)
3. 5 × 1,000 SHELL (= 5 × 10 USDC)
4. 4 × 100 SHELL (= 4 × 1 USDC)
Each lot joins its denomination's queue independently and is sold separately.
## Denominations Work Like Banknotes
The system uses four fixed denominations, similar to paper bills. A lot can only be sold in full — partial selling is not possible.
Choosing a denomination is a trade-off:
* **Smaller denominations** (1, 10 USDC) — sell faster, as even small purchases can fill them
* **Larger denominations** (100, 1,000 USDC) — fewer transactions needed, but may take longer to find a buyer
## Transaction History
On the SHELL token screen, the **Transaction history** section shows all operations:
* **Sent to Accumulator** — SHELL locked when the sell order was placed
* **Received from Accumulator** — SHELL received (from a purchase)
## What Happens Next
After placing your order, your lot waits in the queue. Learn more about status tracking: [Tracking Your Orders](broken://pages/31c5d607b90a0484f3f75aebbe9f54e770806288). About receiving USDC after the sale: [Receiving USDC (Claim)](broken://pages/4a68c01959125f6dcd554e0a91ed8733b8b21b6f).
