# PoolMode Overview

PoolMode allows traders to securely store their assets in a centralized pool account when placing orders, enabling automatic and precise asset transfer upon order fulfillment. 

1. **Order Placement and Asset Storage**:
   * Upon placing an order, a trader's token assets are first deposited into the pool account associated with the trade (Pool).
2. **Order Fulfillment and Asset Transfer**:
   * Once an order is fulfilled, assets are transferred from the trade pool account to the target trader's account.
   * This transfer ensures the smooth completion of the trade and the correct allocation of assets.
3. **Characteristics of the Trade Pool Account**:

   * The pool account is a fixed account.
   * The account structure is defined as: { owner = Pair\_CanisterId; subaccount = null }.
   * This means each trading pair has a uniquely designated owner, the Pair\_CanisterId, with the subaccount being null.
