The simplest user scenario is when a user sells the `KUMA` bond NFT to the `KUMASwap` by calling `sellBond` while the `KIBT` yield is equal or lower that of the bond's coupon. In this case, the Bond is deposited to the `KUMASwap` contract and the user receives newly minted KIBT that can then either be held to earn real-time interest, swapped for other assets, or wrapped and used as collateral in DeFi protocols. This is useful for users who want to earn real-time interest or granulate the value of the bond.

{% hint style="info" %}
The `KUMASwap` contract won't allow users to sell bonds to the contract which have a lower coupon than that of the latest central bank rate.
