# KUMASwap

The `KUMASwap` allows users to sell KUMA NFTs in exchange for `KIBT` using `sellBond`, and buy KUMA NFTs with `KIBT` using `buyBond`. The `KUMASwap` contract is responsible for:

1. Ensuring KIBTokens backing by :
   * Minting `KIBToken` upon KUMA NFT sale
   * Burning `KIBToken` upon KUMA NFT sale purchase
2. Generating fee income for the `KUMADAO`.

There is one `KUMASwap` contract per existing risk category similar to the `KIBToken` .
