# 5-9. Secondary distribution

Regenerative NFTs are based on the Ethereum protocol's ERC721 standard, making them tradable on marketplaces like OpenSea. Additionally, we are considering a mechanism to distribute the profits from secondary sales to the guardians of natural resources. Our goal is to ensure that the circulation of environmental value contributes to the rejuvenation of natural resources and the revitalization of local economies.
