# Trade Yield

Here, you can convert your crypto, such as USDT, into Yield Tokens (YT), which encapsulate the right to the future yield of the corresponding interest-bearing token.

In the top area, you will find the essential details of the pool used for the exchange, including the YT's expiry date and current liquidity.

The tabs below, Buy / Sell, change the intent of the desired action.&#x20;

A YT purchase can be made by providing an underlying or interest-bearing token.

The bottom part of the drawer provides the following output details:

* The number of YT units received alongside their current USD market value
* Min Output - you will not receive less than the displayed amount of YT
* Notional Value Traded—Under the hood, when buying/selling one YT, one PT has to be bought/sold. The notional value encapsulates the total USD value of assets traded to execute the swap.&#x20;
* Implied APY - Current market prediction of an asset's future yield.&#x20;
* Fee - considers Notional Value Traded

To initiate the swap, token approval \[Approve] is required, followed by a swap confirmation \[Buy YT] or \[Sell YT].&#x20;
