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.
Important: once a sell order is confirmed, cancellation is not possible. Your SHELL will remain locked until sold.
Prerequisites
Acki Nacki Wallet app installed
SHELL in your balance (minimum 100 SHELL for the smallest lot)
Step-by-Step Guide
Choose a Lot Denomination
The Sell SHELL panel opens with the prompt "Choose how much USDC you want to receive." Four denominations are available:
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.

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 × 100,000 SHELL (= 1,000 USDC) — if you have enough balance, or skip
1 × 10,000 SHELL (= 100 USDC)
5 × 1,000 SHELL (= 5 × 10 USDC)
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. About receiving USDC after the sale: Receiving USDC (Claim).
