# KUMA Interest Bearing Token (KIBT)

KIBTokens are rebase tokens minted and burned by the `KUMASwap` contract upon sale and purchase of KUMA NFTs. KUMA NFTs back KIBT and determine the yield earned on them. Yield collected by the KUMA NFTs in the `KUMASwap` reserve is distributed to KIBTokens holders directly by increasing their wallet balance on a set interval, referred to as epoch.
