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.

Prerequisites

• Acki Nacki Wallet app installed

• SHELL in your balance (minimum 100 SHELL for the smallest lot)

Step-by-Step Guide

1

Open Exchange

On the wallet's main screen, tap the Exchange button.

2

Select Buy & Sell SHELL

On the Exchange screen you'll see two options. Tap Buy & Sell SHELL (Trade SHELL with USDC).

3

Switch to Sell

On the "Buy & Sell SHELL for USDC" screen, two buttons are displayed at the bottom: Sell and Buy. Tap Sell.

4

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.

5

Confirm the Sale

A confirmation screen appears:

Tap Confirm to proceed or Cancel to go back.

6

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.

7

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.

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)
