BirdRalph has been created by Munich based artist Alexa Wagner. BirdRalph is a collection of 1.089 NFTs on Ethereum. They are based on the CryptoRalph art and attributes which are uniquely combined with the Moonbirds traits. So basically this is the first time a Moonbirds derivative is based on a real person life (just like CryptoRalph).
BirdRalph comes with a set of utilities, e.g. holders will collect CryptoRalph Token ($CRT) and level up their NFT over time for additional benefits.
