# KUMA NFTs

Each KUMA NFT is non-fungible and transferable. They follow the [ERC-721](https://eips.ethereum.org/EIPS/eip-721) standard, the NFT standard. Each token contains metadata that provide details about the underlying asset backing its value.

{% hint style="warning" %}
KUMA NFTs are minted unilaterally by [Mimo Capital AG](/kuma-protocol/kuma-protocol/regulated-nfts/mimo-capital-ag-a-regulated-entity.md). The KUMA DAO has no control over them.

* `country` Treasury issuer - example : US
