Excellent question, RYU is an expansive ecosystem built on the Avalanche blockchain. RYU is a collection of economically incentivized products that consists of the $nRYU token which is deflationary, derivative tokens, and collections of NFTs.
RYU aims to provide utility to our NFT collections. When you hold two RYUs you can breed them using $nRYU and get an egg that will hatch into a Gen2 RYU. All the $nRYU used will be burned.
The Gen2 dragon is a mixture of characteristics of the parent Gen1 dragons.
These NFT RYUs come in two classes: Basic and Legendary. There are only 99 Legendary dragons and 3234 Basic dragons that exist for a maximum supply of 3333 Gen1 RYU NFTs.
