{% tab title="User Funds Manager " %}
To ensure accurate option prices and to maintain transaction orders on Arrow, our router manager submits orders on behalf of users. The router manager must redeem gas from users to place orders for this to work. Hence, users need to deposit gas in AVAX in the User Funds Manager before placing any orders so that the router manager can post the transactions on-chain. Users are also able to withdraw any unused deposited gas funds at any time.
